General Power Tool Safety Warnings

WARNING

Read all safety warnings and all instructions. Failure to follow

the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1) Work area safety

a) Keep work area clean and well lit. Cluttered or dark areas invite accidents. b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes. c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2) Electrical safety

a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges and moving parts. Damaged or entangled cords increase the risk of electric shock.

e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

3) Personal safety

a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. c) Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents. d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

4) Power tool use and care

a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed. b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. c) Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally. d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users. e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

5) Service

a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Safety Warnings for Angle Grinder

Safety Warnings common for Grinding, Sanding, Wire Brushing or Abrasive Cutting Off Operations

This power tool is intended to function as a grinder, sander, wire brush, or cut-off tool. Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury. This power tool is not recommended for polishing. Operations for which the power tool was not designed may create a hazard and cause personal injury. Do not use accessories that are not specifically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool does not assure safe operation. The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fly apart. The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled. The arbor size of wheels, flanges, backing pads, or any other accessory must properly fit the spindle of the power tool. Accessories with arbor holes that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively, and may cause loss of control.

Do not use a damaged accessory. Before each use, inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If the power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time. Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss. Keep bystanders a safe distance away from the work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation. Hold power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and shock the operator. Position the cord clear of the spinning accessory. If you lose control of the power tool, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory. Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control.

Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body. Regularly clean the power tool's air vents. The motor's fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards. Do not operate the power tool near flammable materials. Sparks could ignite these materials. Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

Kickback and related warnings

• Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory's rotation at the point of the binding.

For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel's movement at the point of pinching. Abrasive wheels may also break under these conditions.

Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.

• Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during

start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken.

• Never place your hand near the rotating accessory. Accessory may kickback over your hand.
• Do not position your body in the area where power tool will move if kickback occurs. Kickback will propel the tool in direction opposite to the wheel's movement at the point of snagging.
• Use special care when working corners, sharp edges, etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback. Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control over the power tool.

Additional safety instructions for grinding and cutting off operations

• Use only wheel types that are recommended for your power tool and the specific guard designed for the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe. The guard must be securely attached to the power tool and positioned for maximum safety, so the least amount of wheel is exposed towards the operator. The guard helps to protect operator from broken wheel fragments and accidental contact with wheel.
• Wheels must be used only for recommended applications. For example: do not grind with the side of the cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding; side forces applied to these wheels may cause them to shatter. Always use undamaged wheel flanges that are of correct size and shape for your selected wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage. Flanges for cut-off wheels may be different from grinding wheel flanges.

Do not use worn down wheels from larger power tools. Wheels intended for larger power tools are not suitable for the higher speed of a smaller tool and may burst.

Additional safety warnings specific for abrasive cutting off operations

Do not "jam" the cut-off wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage. Do not position your body in line with and behind the rotating wheel. When the wheel, at the point of operation, is moving away from your body, the possible kickback may propel the spinning wheel and the power tool directly at you. When wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the cut-off wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate and take corrective action to eliminate the cause of wheel binding. Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully reenter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece. Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel. Use extra caution when making a "pocket cut" into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.

Safety warnings specific for sanding operations

Do not use excessively oversized sanding disc paper. Follow manufacturers recommendations, when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc, or kickback.

Safety warnings specific for wire brushing operations

• Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress the wires by applying excessive load to the brush. The wire bristles can easily penetrate light clothing and/or skin. If the use of a guard is recommended for wire brushing, do not allow any interference of the wire wheel or brush with the guard. Wire wheel or brush may expand in diameter due to work load and centrifugal forces.

Additional safety warnings

Wear safety goggles.

• Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property damage or may cause an electric shock. Release the On/Off switch and set it to the off position when the power supply is interrupted, e.g., in case of a power failure or when the mains plug is pulled. This prevents uncontrolled restarting.
• When working stone, use dust extraction. The vacuum cleaner must be approved for the extraction of stone dust. Using this equipment reduces dust-related hazards.

Use a cutting guide when cutting stone. Without sideward guidance, the cutting disc can jam and cause kickback. - When working with the machine, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more secure with both hands. - Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand. - Keep your workplace clean. Blends of materials are particularly dangerous. Dust from light alloys can burn or explode. - Never use the machine with a damaged cable. Do not touch the damaged cable and pull the mains plug when the cable is damaged while working. Damaged cables increase the risk of an electric shock.

Products sold in GB only: Your product is fitted with a BS 1363/A approved electric plug with internal fuse (ASTA approved to BS 1362).

If the plug is not suitable for your socket outlets, it should be cut off and an appropriate plug fitted in its place by an authorized customer service agent. The replacement plug should have the same fuse rating as the original plug.

The severed plug must be disposed of to avoid a possible shock hazard and should never be inserted into a mains socket elsewhere.

The electronic reduced starting current limits the power consumption when switching the tool on and enables operation from a 13 ampere fuse.

Working Advice

Exercise caution when cutting slots in structural walls; see Section "Information on Structures". - Clamp the workpiece if it does not remain stationary due to its own weight. Do not strain the machine so heavily that it comes to a standstill.

After heavily straining the power tool, continue to run it at no-load for several minutes to cool down the cutting/grinding tool. Grinding and cutting discs become very hot while working; do not touch until they have cooled. Do not use the power tool with a cut-off stand.

Rough Grinding

Never use a cutting disc for roughing.

The best roughing results are achieved when setting the machine at an angle of 30° to 40°. Move the machine back and forth with moderate pressure. In this manner, the workpiece will not become too hot, does not discolour and no grooves are formed.

Flap Disc

With the flap disc (accessory), curved surfaces and profiles can be worked.

Flap discs have a considerably higher service life, lower noise levels and lower sanding temperatures than conventional sanding sheets.

Cutting Metal

For cutting metal, always work with the cutting guard for cutting 7.

When cutting, work with moderate feed, adapted to the material being cut. Do not exert pressure onto the cutting disc, tilt or oscillate the machine.

Do not reduce the speed of running down cutting discs by applying sideward pressure.

The machine must always work in an up-grinding motion. Otherwise, the danger exists of it being pushed uncontrolled out of the cut.

When cutting profiles and square bar, it is best to start at the smallest cross section.

Cutting Stone

For cutting stone, always work with the cutting guide with dust extraction protection guard 20. The machine may be used only for dry cutting/grinding.

For cutting stone, it is best to use a diamond cutting disc. As a safety measure against jamming, the cutting guide with dust extraction protection guard 20 must be used.

Operate the machine only with dust extraction and additionally wear a dust protection mask.

The vacuum cleaner must be approved for the extraction of masonry dust. Bosch provides suitable vacuum cleaners.

Switch on the machine and place the front part of the cutting guide on the workpiece. Slide the machine with moderate feed, adapted to the material to be worked.

For cutting especially hard material, e.g., concrete with high pebble content, the diamond cutting disc can overheat and become damaged as a result. This is clearly indicated by circular sparking, rotating with the diamond cutting disc. In this case, interrupt the cutting process and allow the diamond cutting disc to cool by running the machine for a short time at maximum speed with no load.

Noticeable decreasing work progress and circular sparking are indications of a diamond cutting disc that has become dull. Briefly cutting into abrasive material (e.g. lime-sand brick) can reshape the disc again.

Information on Structures

Slots in structural walls are subject to the Standard DIN 1053 Part 1, or country-specific regulations.

These regulations are to be observed under all circumstances. Before beginning work, consult the responsible structural engineer, architect or the construction supervisor.

Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull the mains plug. For safe and proper working, always keep the machine and ventilation slots clean. In extreme working conditions, conductive dust can accumulate in the interior of the machine when working with metal. The protective insulation of the machine can be degraded. The use of a stationary extraction system is recommended in such cases as well as frequently blowing out the ventilation slots and installing a residual current device (RCD).

Please store and handle the accessory(-ies) carefully.

If the machine should fail despite the care taken in manufacturing and testing procedures, repair should be carried out by an after-sales service centre for Bosch power tools.

In all correspondence and spare parts order, please always include the 10-digit article number given on the type plate of the machine.

Assembly

Power tools that cannot be switched on or off are dangerous and must be repaired.

B) Before adjusting or replacing accessories, or before storing the power tool, disconnect it from the power supply and/or remove the battery pack. This precautionary measure reduces the risk of accidental starting. C) Store power tools out of the reach of children. Do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users. D) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. E) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

F) Use the power tool, accessories and tool bits etc., in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

5) Service

a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Safety instructions for angle grinders

General safety warnings for grinding, sanding, wire brushing, and cutting-off operations

This power tool is intended to function as a grinder, sander, wire brush, or cut-off tool. Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow the instructions listed below may result in electric shock, fire, and/or serious injury. This power tool is not intended for polishing. Operations for which the power tool was not designed may create a hazard and cause personal injury. Do not use accessories not specifically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.

The permissible speed of the working tool must be at least the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fly apart. The outside diameter and thickness of the working tool must be within the capacity rating of your power tool. Incorrectly sized workpieces cannot be adequately guarded or controlled. Grinding wheels, flanges, backing pads, or any other accessories must fit the spindle of your power tool. Workpieces that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively, and may cause loss of control. Do not use damaged working tools. Before each use, inspect working tools such as grinding wheels for chips and cracks, grinding discs for cracks, tears, or excess wear, and wire brushes for loose or broken wires. After inspection, place the working tool and all persons in the area at a safe distance from the plane of rotation of the working tool, then run the power tool at maximum no-load speed for one minute. Damaged working tools will normally break apart during this test time. Use personal protective equipment depending on the work you are performing. Use safety glasses, a dust mask, or safety goggles. As appropriate, use a dust mask, hearing protection, protective gloves, or a workshop apron capable of stopping small abrasive or workpiece fragments.

Russian | 237

Always wear protective equipment. Dust masks must be used when performing various works. Respiratory protective masks must filter out dust generated during work. Prolonged exposure to strong noise can lead to hearing loss.

Make sure that all people are at a safe distance from the work area. Every person within the work area must have personal protective equipment. Fragments of workpieces or broken tools may fly away and cause injury beyond the immediate work area. Hold the power tool only by insulated gripping surfaces when performing work where the cutting tool may contact hidden wiring or its own cord. Contact with a live wire may energize metal parts of the power tool and lead to electric shock. Keep the power cord away from the rotating accessory. If you lose control of the tool, the cord may be cut or caught by the rotating accessory and your hand or arm may be pulled into the rotating accessory. Never release the power tool from your hands until the accessory has completely stopped. A rotating accessory may catch on a surface and cause you to lose control of the power tool. Switch off the power tool when transporting it. Loose clothing may be accidentally caught by the rotating accessory and cause injury.

Regularly clean the ventilation slots of your power tool. The motor fan draws dust into the housing, and excessive accumulation of metal dust can lead to electrical hazards. Do not use the power tool near flammable materials. Sparks may ignite these materials. Do not use accessories that require liquid coolants. Using water or other liquid coolants may lead to electric shock.

Reverse and corresponding precautionary instructions

Kickback is a sudden reaction resulting from a pinched or jammed rotating accessory, such as a grinding wheel, grinding disc, wire brush, etc., causing a sudden stop of the rotating accessory. In this case, the uncontrolled power tool accelerates at the point of jamming in the direction opposite to the rotation of the accessory. If a grinding wheel snags or jams in the workpiece, the edge of the wheel that is immersed in the workpiece may catch and cause the wheel to jump out or kickback. The wheel then moves toward or away from the operator, depending on the direction of rotation at the point of jamming. The grinding wheel may also break.

Kickback is a result of improper use of the power tool and can be prevented by the precautions described below.

Hold the power tool firmly with both hands and position your body and arms to resist kickback forces. If a auxiliary handle is available, always use it to have maximum control over kickback or reaction torque at start-up. The operator can control kickback forces with appropriate precautions. Your hand should never be near the rotating accessory. In case of kickback, the tool may jump toward your hand. Position yourself away from the area where the power tool will be moved during kickback. Kickback moves the power tool in the direction opposite to the movement of the grinding disc at the point of binding.

Work particularly carefully on corners, sharp edges, etc. Prevent the tool from bouncing and jamming. The rotating accessory tends to jam on corners, sharp edges, or when it bounces. This causes loss of control or kickback. Do not use toothed saw blades or other toothed accessories. Such accessories often cause kickback or loss of control over the power tool.

Special safety instructions for grinding and cutting

Use only the abrasive accessories specified for your power tool and the protective guard provided for them. Abrasive accessories not intended for this power tool cannot be adequately guarded and are unsafe.

The protective guard must be securely attached to the power tool and adjusted to achieve the maximum degree of safety, i.e., the smallest possible part of the abrasive accessory should be exposed towards the operator. The protective guard must protect the operator from fragments and accidental contact with the abrasive accessory. Abrasive accessories may only be used for the recommended applications. For example: never grind with the side surface of a cutting disc. Cutting discs are intended for cutting material with the edge. Lateral forces on these abrasive accessories can break them. Always use undamaged flanges with the correct dimensions and shape for the selected cutting disc. Correct flanges support the cutting disc and reduce the risk of breakage. Flanges for cutting discs may differ from flanges for grinding discs. Do not use worn-out flanges for larger power tools. Flanges for larger power tools are not designed for the high speeds of smaller power tools and may break.

Additional special safety instructions for cutting with a cutting disc

Prevent jamming and overloading of the cut-off wheel. Do not make excessively deep cuts. Overloading the cut-off wheel increases its load and susceptibility to twisting or jamming, and thus the possibility of kickback or wheel breakage.

Do not position your body in line with the rotating cut-off wheel. If the cut-off wheel kicks back, the power tool may jump directly toward you. When the cut-off wheel is jammed or when you interrupt a cut, switch off the power tool and hold it steady until the wheel has come to a complete stop. Never attempt to pull the rotating cut-off wheel out of the cut while it is still moving, as this may cause kickback. Investigate and take corrective action to eliminate the cause of wheel jamming. Do not restart the power tool while the abrasive wheel is still in the workpiece. Allow the cut-off wheel to reach full speed before carefully continuing the cut. Otherwise, the wheel may bind, jump out of the workpiece, or cause kickback. Support large workpieces to minimize the risk of kickback from a jammed wheel. Large workpieces may sag under their own weight. The workpiece must be supported on both sides, near the cut and at the edges. Be especially careful when making cuts in walls or other areas where you cannot see what is behind. The protruding cut-off wheel may cut into gas or water pipes, electrical wiring, or other objects and cause kickback.

Special safety instructions for sanding with sanding sheets

Do not use sanding sheets larger than the sanding pad; follow the manufacturer's recommendations regarding sanding sheet sizes. Sanding sheets that extend beyond the sanding pad can cause injury, snagging, tearing, or kickback.

Special safety instructions for working with wire brushes

Be aware that wire brushes lose bristles even during normal operation. Do not overload the wire brush by applying excessive pressure. The wire bristles can easily penetrate thin clothing and/or skin. If protective gloves are recommended for the work, avoid contact between the wire brush and the gloves. Disc and cup brushes may increase in diameter under the influence of centrifugal force.

Additional safety instructions

Wear protective goggles.

WARNING: Read the corresponding safety instructions for locating pipes and cables in walls. Contact the local utility company for information. Contact with electrical wires can lead to electric shock. Damage to gas pipes can lead to explosion. Damage to water pipes leads to property damage and can cause electric shock. Remove the lock-off switch and set it to the locked position if there is a power failure, for example, if the electricity goes out or the plug is pulled from the outlet. This prevents accidental restarting. When cutting, use a vacuum cleaner. The vacuum cleaner must be approved for collecting stone dust. Using such devices reduces the risk from dust.

For cutting, use guide rails. Without side guide, the cutting disc may jam and cause kickback. Always hold the power tool with both hands and maintain a stable stance. With both hands you work more reliably with the power tool. Clamping the workpiece. A workpiece clamped in a clamping device or in a vise is held more securely than in your hand. Keep your work area clean. Mixtures of materials are especially dangerous. Dust from colored metals can ignite or explode. Do not work with a power tool with a damaged cord or plug. Do not touch a damaged cord; disconnect the plug from the outlet if the cord was damaged during work. A damaged cord increases the risk of electric shock.

The protective hood is installed in the same way as the protective hood for sanding.

Additional handle

Use the power tool only with the additional handle 3.

Screw the additional handle 3 on the right or left of the gearbox head depending on the method of work.

Vibration handle

Vibration Control

The vibration handle reduces the vibration level and provides more comfortable work. Never work without the additional handle.

Do not use a damaged additional handle.

Protective guard for sanding

For work with a sanding plate, or with a cup-shaped wire brush, or with a flap disc, install the protective guard 14.

Secure the protective guard 14 with the additional handle 3.

Mounting the sanding tools

Before any work on the power tool, pull the plug out of the socket. During work, the sanding and cutting discs become very hot; do not touch them until they have cooled down.

Mount the sanding tool 4 and all parts to be mounted.

The power tool is locked by pressing the spindle lock button only when the spindle is at a standstill! Otherwise, the power tool may be damaged.

Diamond cutting discs

Observe the dimensions of the diamond tools. The hole diameter must correspond to the mounting flange. Do not use adapters or reducers.

When using diamond cutting discs, ensure that the direction of rotation arrow on the diamond cutting disc matches the direction of rotation of the power tool (see arrow on the gear head).

The assembly sequence is shown on the illustration page.

Observe the applicable regulations in your country for the materials being processed.

Working with the machine

Switching the power tool on

Pay attention to the mains voltage! The voltage of the power source must match the data on the rating plate of the power tool. Power tools rated for 230 V can also operate at 220 V.

When operating the power tool from mobile generators that do not have sufficient power reserve or are not equipped with a suitable voltage regulator with starting current boost, power loss or unusual behavior of the power tool may occur upon switching on. Please observe the suitability of the generator you are using, especially with regard to voltage and mains frequency.

Switching on/off

To switch on the power tool, push the on/off switch 2 forward and then press it.

To switch off the power tool, release the on/off switch 2.

Check the diamond tool before use. The diamond tool must be mounted faultlessly and rotate freely. Perform a trial run for at least 1 minute without load. Do not use damaged, out-of-round or vibrating diamond tools. Damaged diamond tools can burst and cause injury.

Starting current limiting (PWS 20-230 J)

The soft-start system limits the power when switching on the power tool and allows operation from a 16 A socket.

Application instructions

Be careful when working in walls with concealed cables, see section "Instructions for installation". Secure the workpiece if its own weight does not ensure a stable position. Do not overload the power tool until it has stopped. The power tool can be cooled after high load by letting it run at idle for a few minutes. When working, the inserted tools and cutting discs heat up, do not touch them until they have cooled down. Do not use the power tool on an abrasive cutting station.

Surface sanding

Never use cutting discs for sanding!

With the disc at an angle of 30° to 40° to the workpiece, you will get the best results when surface sanding. Guide the power tool with moderate pressure back and forth. The workpiece does not heat up strongly, does not change its color, and no grooves remain.

Flap disc

With a flap disc (accessory), you can also work on curved surfaces and profiles (contour sanding).

Flap discs have a significantly longer service life, produce less noise and lower grinding temperature than conventional sanding discs.

Cutting metal materials

For cutting work on metal, only use the protective guard for cutting.

When cutting with a cutting disc, work with moderate feed, appropriate to the material being processed. Do not exert pressure on the cutting disc, do not tilt or rock it.

Do not brake the cutting disc with lateral pressure.

Always guide the power tool against the direction of rotation. Otherwise, there is a risk of uncontrolled kickback from the cut.

When cutting profiles and square tubes, start the cut at the smallest cross-section.

Cutting stones

Use the cutting machine only with protective goggles and a guide rail 20. The power tool is intended only for dry cutting and dry grinding.

For cutting stone, a diamond cutting disc is best. To prevent overheating, allow the disc to run at no load for a short time before starting the cutting work with guide rail 20.

Work only with a dust extraction system and additionally wear a protective respirator.

The dust extraction connection is designed for stone dust. Bosch offers suitable dust extraction hoses.

Russian | 247

Switch on the power tool and set the guide rail on the workpiece. Guide the power tool with moderate feed, appropriate to the material being processed.

When processing very hard materials, e.g., concrete with a high content of gravel, the diamond cutting disc may overheat and be damaged. A rotating spark ring clearly indicates this.

In such a case, interrupt the process and let the diamond cutting disc run at no load at maximum speed for a short time.

A significant decrease in performance and a rotating spark ring indicate that the diamond cutting disc is worn.

You can sharpen the diamond cutting disc with short cuts in an abrasive material (e.g., in sand-lime brick).

Instructions for static

In Germany, the standard DIN 1053 part 1 and the specific regulations of the respective country apply.

These regulations must be observed. Before starting work, consult the responsible structural engineer, architect, or site manager.

Thanks to the round shape, you can also process the inner surfaces and profiles.

Thanks to the movable round knives, the service life is mutually extended, they are significantly less worn and have a lower temperature of their transmission than movable knives.

CUTTING METAL

riangleright When cutting metal, always use the protective cover for cutting.

When cutting, work with a gentle pushing of the tool in accordance with the material being processed. Do not press on the cutting wheel, do not tilt it or bend it.

After finishing work, do not stop the cutting wheel by pressing it from the side.

Cutting must always be done against the direction of rotation. Otherwise, there is a risk of uncontrolled

movement.

Removing the electric plug from the socket.

When cutting profiles and

square tubes, it is better to start from the smallest cross-section.

CUTTING STONE

riangleright When cutting stone, always use the dust guard for cutting with a diamond cutting disc. The electric tool can also be used for dry cutting/dry grinding.

For cutting stone, it is best to use a diamond cutting wheel. For safety reasons, it is necessary to use the dust guard for cutting with a diamond cutting disc.

Pull the electric tool away from the cut only when it is running and slowly tilt the cut open.

Please make sure to use only original accessories. Bosch will be liable for damages caused by the use of non-original accessories.

Remove the power tool and the accessory from the workpiece only after it has come to a complete stop. Slowly move the power tool

according to the material being processed.

When cutting materials with hard components, e.g., concrete with high pebble content, the diamond cutting disc may become blocked, which leads to its jamming. This is indicated by a noticeable sparking around the diamond cutting disc.

In this case, stop cutting and let the diamond cutting disc run at no load for a short time at maximum speed until it is free again.

Very slow feed and visible sparking are signs that the diamond cutting disc has become dull. You can sharpen it again by making short cuts in an abrasive material, e.g., in sandstone or lime sandstone.

Disposal

Power tools, accessories and packaging must be disposed of at an ecological recycling station.

1) Safety at the workplace

a) Keep your work area clean and well lit. Cluttered or dark areas can lead to accidents. b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes. c) Keep children and bystanders at a safe distance while operating a power tool. Distractions can cause you to lose control.

2) Electrical safety

a) The power tool plug must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

3) Safe work practices

a) Be concentrated, follow carefully the instructions and act reasonably. Do not use the power tool when you are tired or under the influence of drugs, alcohol, or medication. A moment of inattention while working with the power tool may lead to serious personal injury.

b) Work with protective equipment and always wear safety glasses. Wearing personal protective equipment, such as a dust mask, non-slip safety shoes, a hard hat, or hearing protection (earplugs), depending on the type of work, reduces the risk of injury. c) Avoid accidental starting. Before connecting the tool to the power source and/or battery pack, make sure the switch is in the off position. Carrying the power tool with your finger on the switch or connecting it to the power source with the switch on can lead to accidents. d) Remove any adjusting key or wrench before turning the power tool on. A wrench or key left attached to a rotating part of the power tool may result in personal injury. e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.

g) If dust extraction and collection equipment is available, make sure it is connected and properly used. Use of dust collection can reduce dust-related hazards.

h) This applies to power tools.

a) Do not use the power tool. Use the power tool only for its intended purpose. You will work better and more safely when you use the power tool within the range specified by the manufacturer. b) Do not use the power tool if the switch is damaged. A power tool that cannot be turned on and off with the switch is dangerous and must be repaired. c) Unplug the power tool and/or remove the battery pack before making adjustments, changing accessories, or storing the power tool. Such preventive safety measures reduce the risk of starting the power tool accidentally. d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.

a) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. b) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. c) Use the power tool, accessories and tool bits etc., in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

5) Maintenance

a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Safety instructions for all operations

General power tool safety warnings for grinding, sanding, wire brushing, polishing or abrasive cutting-off operations

This power tool is intended to function as a grinder, sander, wire brush, polisher or cut-off tool. Read all safety warnings, instructions, illustrations and specifications provided with this power tool.

Warnings common for grinding, sanding, wire brushing, polishing or abrasive cutting-off operations: This power tool is intended to function as a grinder, sander, wire brush, polisher or cut-off tool. Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

Electrical power tool safety warnings. Pulling the tool, for which the electrical tool is not intended, may be dangerous and may lead to injury. Do not use accessories that are not specifically recommended by the manufacturer for this electrical tool. The fact that you can attach a certain accessory to the machine or work with the tool does not guarantee safe operation with it. The rated speed of the working tool must be at least equal to the maximum speed marked on the electrical tool. Working tools that rotate at a higher speed than the rated one may break and fly apart. The diameter and thickness of the working tool must correspond to the data given in the technical characteristics of your electrical tool. Working tools with incorrect dimensions cannot be adequately shielded or controlled. Discs, flanges, backing pads or other accessories must fit exactly on the spindle of your electrical tool. Working tools that do not fit exactly on the spindle of the electrical tool rotate unevenly, vibrate strongly and may lead to loss of control.

Do not use damaged working tools. Before each use, check the working tools, e.g. abrasive discs for cracks or tears, backing pads for cracks or excessive wear, wire brushes for loose or broken wires. If you drop the electrical tool or the working tool, check carefully for damage or use a new undamaged working tool. After you have checked and mounted the working tool, let the electrical tool run at maximum speed for one minute; hold it and keep your face away from the plane of rotation. Damaged working tools usually break during this test period. Work with personal protective equipment. Depending on the application, use a face shield, eye protection or safety glasses. If necessary, use a dust mask, hearing protection (anti-noise), work gloves and a special apron that protects against small abrasive particles. Your eyes must be protected from flying particles in the work area. The anti-dust and protective mask filters the dust generated during work. If you are exposed to loud noise for a long time, this may lead to hearing loss. Keep other people at a safe distance from the work area. Anyone who is in the work area must wear personal protective equipment. Fragments of the workpiece or of a broken working tool may fly off at high speed and cause injury beyond the work area.

Keep the power tool away from hidden electrical wiring. Contact with a live wire can make the metal parts of the power tool live and can cause an electric shock. Keep a safe distance from rotating power tools. If you lose control of the power tool, the cable may be cut or caught by the rotating tool, which can cause injury, e.g., to the hand. Never leave the power tool running unattended. The rotating tool may catch on an object, causing you to lose control of the power tool. When you are not using the power tool, do not leave it switched on. If you are distracted or stumble, the rotating tool may catch on your clothing, and as a result, the tool may cut into your body. Regularly clean the ventilation openings of your power tool. The fan of the motor draws dust into the housing, and excessive accumulation of metal dust increases the risk of electric shock. Do not use the power tool near flammable materials. Sparks can ignite such materials. Do not use power tools that require liquid coolants. Using water or other liquid coolants can cause an electric shock.

Disposal and recycling information

Kickback is a sudden reaction of the power tool to a jammed or blocked rotating accessory, e.g. grinding disc, sanding disc, wire brush, etc. Jamming or blocking leads to a sudden stop of the rotating accessory. As a result, the power tool is accelerated uncontrollably in the direction opposite to the direction of rotation of the accessory at the point of blocking, and becomes uncontrollable. If, for example, a grinding disc jams or blocks in the workpiece, the edge of the disc that dips into the material can catch and tear the disc out or cause a kickback. In such a case, the disc accelerates towards the operator or in the opposite direction, depending on the direction of rotation of the disc and the point of jamming. In such cases, grinding discs can also break. Kickback results from improper or incorrect use of the power tool. It can be prevented by taking suitable precautionary measures, as described below. Hold the power tool firmly with both hands and position your arms so that you can withstand any kickback forces. Always use the auxiliary handle, if provided, to have maximum control over kickback or reaction torque during start-up. If precautionary measures are taken, you can control the machine in the event of kickback or reaction torque. Never place your hands near rotating accessories. If kickback occurs, the tool may cut your hand. Avoid positioning your body in the area where the power tool would move in case of kickback. Kickback will propel the tool in the direction opposite to the movement of the accessory at the point of blocking.

Workpieces, edges, and sharp objects. Avoid searching for or jamming rotating accessories in the workpiece. When working on edges or sharp objects or when abruptly pulling the rotating accessory out, there is an increased risk of jamming. This leads to loss of control over the machine or kickback. Do not use blunt or damaged discs. Such accessories tend to cause kickback or loss of control over the power tool.

Special safety instructions for grinding and cutting with grinding discs.

The guard provided with the tool must be securely attached to the power tool and positioned for maximum safety, so that the least amount of the abrasive disc is exposed towards the operator. The guard helps to protect the operator from broken wheel fragments and accidental contact with the grinding wheel. Use the abrasive discs only for the intended purposes. For example: never grind with the side surface of the disc. Cutting discs are intended for removing material with the edge of the disc. Side grinding with these discs can cause them to break.

Always use undamaged flanges that are the correct size and shape for the abrasive disc you have selected. Proper flanges support the disc and reduce the risk of disc breakage. Flanges for cutting discs may differ from those for grinding discs. Do not use worn-down abrasive discs from larger power tools. Discs intended for larger power tools are not suitable for the higher speeds of smaller tools and may burst.

Safety warnings for cutting-off operations

Avoid jamming the cutting disc or applying excessive pressure. Do not attempt to make excessively deep cuts. Overstressing the disc increases the load and susceptibility to twisting or jamming, which can lead to kickback or disc breakage. When the disc is pinched or jammed, the power tool may kick back violently towards you. If the disc becomes jammed or if you interrupt a cut, switch off the power tool and hold it steady until the disc has come to a complete stop. Never attempt to remove a still-moving disc from the cut, as this could cause kickback. Investigate and correct the cause of the jamming. Do not restart the power tool while the disc is in the workpiece. Allow the disc to reach full speed before carefully continuing the cut.

Otherwise, the disc may jam, jump out of the workpiece, or cause kickback.

Support the working position. Mixing different materials can be especially dangerous. Thin parts made of sheet metal can cut themselves. Do not use electric tools when the cable is damaged. If the cable is damaged during work, do not touch it; immediately disconnect the plug from the contact.

Damaged or tangled cables increase the risk of electric shock.

You can find the impact on the catalog number on the nameplate of the electric tool. The trade names of some electric tools may be changed.

Safety for electric tools without restriction on starting current: When switching on, a short-term voltage drop in the supply network may occur. Under unfavorable mains conditions, other electric devices may be affected. If the supply network impedance is less than 0.25 ohms, no disturbances are expected.

Information about use and selection

The measurements are carried out according to EN 60745.

The noise level of the device is typically: sound pressure level 92 dB(A); sound power level 103 dB(A). Uncertainty K=3 dB.

Wear hearing protection!

The vibration total value (vector sum of three directions) is determined according to EN 60745:

Surface grinding (rough grinding, cutting): vibration emission

a_h=8 m / s² , uncertainty K=1.5 m/s². Grinding with sandpaper: vibration emission a_h=3.5 m / s² , uncertainty K=1.5 m/s².

The vibration emission level given in this operating manual has been measured in accordance with the procedure defined in EN 60745 and can be used for comparison with other electric tools. It is also suitable for a preliminary assessment of the vibration load.

The stated vibration emission level is representative for the main applications of the electric tool. However, if the electric tool is used for other purposes, with different accessories or if it is not maintained properly, the vibration emission level may differ. This could significantly increase the total vibration load during the working process.

For an accurate assessment of the vibration load, the periods when the electric tool is switched off or running but not actually in use should also be taken into account. This could significantly reduce the total vibration load.

Take additional safety measures to protect the operator from the effects of vibration, such as: servicing the electric tool and the working tools, keeping the hands warm, and organizing the work processes appropriately.

Sample processing of material. Add.

When cutting materials, e.g. concrete with high reinforcement, diamond discs can overheat and be damaged. Indication of this is discoloration.

In such a case, reduce the feed rate and let the diamond disc cool down by running it idle for some time at maximum speed.

High cutting speed and overheating of the disc are indicated for the diamond disc. You can avoid this with short cutting intervals in abrasive material, e.g. sand-lime brick.

Instructions for stationary use

Cutting of channels in masonry must comply with the requirements of standard DIN 1053 Part 1 or the corresponding national regulations.

These instructions must be strictly followed. Before starting work, consult with the responsible structural engineer, architect, or construction manager.

Maintenance and service

Maintenance and cleaning

● Performing maintenance and cleaning activities on electrical tools must be done with the mains disconnected. For quality and safe work, keep the electrical tool and ventilation openings clean. ● Electrical tools can produce sparks when cutting metal, which may deposit on the inside of the housing. This can damage the insulation of the electrical tool. In such a case, use a stationary extraction system, ensure adequate ventilation of the openings, and connect the electrical tool through a residual current device (RCD).

Store and handle

Accessories carefully.

If, despite careful production and testing, damage occurs, the electrical tool must be sent for repair to an authorized service center for electrical tools.

When contacting the representatives, please always specify the 10-digit identification number on the rating plate of the electrical tool.
