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.
Work area safety
- Keep work area clean and well lit. Cluttered or dark areas invite accidents.
▶ 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.
▶ Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical safety
▶ 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.
▶ 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.
▶ Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
▶ 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.
- 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.








English | 25
▶ 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.
Personal safety
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.
▶ 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.
▶ 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.
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.
▶ Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
▶ 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.
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.
Power tool use and care
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.
▶ 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.
▶ 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.
▶ 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.
- 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.
▶ Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
▶ 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.
Service
▶ 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 Straight Grinders
Safety Warnings Common for Grinding
This power tool is intended to function as a grinder. 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 sandpaper grinding, wire brushing, polishing and abrasive cut-off operations. Operations for which the power tool was not designed may create a hazard and cause personal injury.
Do not use accessories which are 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 rated speed of the grinding accessory must be at least equal to the maximum speed marked on the power tool. Grinding accessories rotating faster than their permitted speed can break and fly around.
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 arbour size of wheels, sanding drums or any other accessory must properly fit the spindle or collet of the power tool. Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
▶ Mandrel-mounted wheels, grinding cylinders, cutting tools or other accessories must be inserted fully into the collet or chuck. The "protrusion" or exposed part of the mandrel between grinding accessory and collet or chuck must be minimal. If the mandrel is not sufficiently clamped or the grinding accessory is too far forward, the accessory may become loose and be ejected at great speed.
Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, sanding drum for cracks, tear or excess wear, wire brush for loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders





26 | English
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 shop 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 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 the power tool only by the insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own connecting cable. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
▶ Always hold the tool firmly in your hand(s) during the start-up. The reaction torque of the motor, as it accelerates to full speed, can cause the tool to twist.
▶ If possible, use clamps to fix the workpiece. Never hold a small workpiece in one hand whilst operating the power tool in the other. Clamping small workpieces gives you both hands free to better control the power tool. Round workpieces such as wooden dowels, bars or pipes tend to roll away when being cut, which can cause the accessory to jam and be hurled towards you.
▶ Position the connecting cable clear of the spinning accessory. If you lose control of the power tool, the connecting cable 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 wheel may grab the surface and pull the power tool out of your control.
▶ After changing the bits or making any adjustments, make sure the collet nut, chuck or any other adjustment devices are securely tightened. Loose adjustment devices can unexpectedly shift, causing loss of control, loose rotating components will be violently thrown.
▶ 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, belt, 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.
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. The operator can control kickback forces, if proper precautions are taken.
▶ Especial 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 use a toothed saw blade. Such blades create frequent kickback and loss of control over the power tool.
▶ Always feed the accessory into the material in the same direction in which the cutting edge exits the material (the same direction in which the chips are ejected). Feeding the power tool in the wrong direction causes the cutting edge of the accessory to run out of the workpiece, which causes the power tool to be pulled in this feed direction.
▶ Always clamp the workpiece securely when using rotating files, high-speed routing bits or carbide routing bits. These accessories snag in the groove even upon slight tilting and can cause kickback. If rotating files, high-speed routing bits or carbide routing bits snag, the accessory can jump out of the groove and lead to loss of control over the power tool.
Additional safety instructions for grinding
▶ Use only wheel types that are recommended for your power tool and only for recommended applications. For example: do not grind with the side of a cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter.
For threaded abrasive cones and plugs use only undamaged wheel mandrels with an unrelieved shoulder flange that are of correct size and length. Proper mandrels will reduce the possibility of breakage.






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.
Do not touch abrasive wheels until they have cooled down. The discs can become very hot while working.
▶ Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
Connect the machine to a mains supply with proper earthing connection. Socket outlet and extension cable must be equipped with an operative protective conductor.
Products sold in AUS and NZ only: Use a residual current device (RCD) with a rated residual current of 30 mA or less.
Safety Warnings for the Power Supply of High-frequency Tools
The safety warnings and working instructions of the frequency converter are to be strictly observed! For detailed information, contact the manufacturer of the frequency converter.
The frequency converter must be secured with a residual current protection device when working in an environment where special protection for persons is necessary. The special protection of persons is required, for example, when working in damp rooms or with materials that can produce current-conducting dust. Not using a residual current protection device can lead to electrical shock, risk of fire, or serious injuries.
The residual current protection device should be installed in the power supply network only by a qualified electrician. Only in this manner can proper functioning be ensured.
The output voltage and frequency of the frequency converter must correspond with the data on the type plate of the high-frequency tool.
▶ Operate the power tool exclusively with a fitting plug. The CEE plug must be dimensioned for the nominal current that the power tool requires (see "Technical Data").
▶ Plug mounting and connection to the power supply is to be carried out by a qualified electrician trained in handling high-frequency tool systems.
▶ Use only original cables! Before each use, check the power tool, cable and plug for possible damage. Cables and plugs may not be repaired, but must be exchanged in order to avoid danger.

Noise/Vibration Information
Sound emission values determined according to EN 60745-2-23.
The vibration level given in this information sheet has been measured in accordance with a standardised test given in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure. The declared vibration emission level represents the main applications of the tool. However if the tool is used for different applications, with different accessories or insertion tools or is poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

Assembly
▶ Disconnect the power supply before making any adjustments, changing accessories, or placing the machine aside. This safety measure prevents accidental starting of the power tool.
Mounting of the Extension (see figure A) (Type 0 602 238 ...)
Depending on the application, the grinder spindle can be extended up to 450 mm. For this purpose, extension with 150 mm (article number 3 606 120 031) and 300 mm (article number 3 606 120 032) are available as an accessory.
▶ When working with an extension, the effective force on the grinder spindle must not exceed 15 N (max.)! This corresponds with a grinding-point load of 1.5 kg. Otherwise, the grinder spindle can break.
Loosening the Grinder Spindle
- Heat up the spindle housing 5 in the area of the threaded sleeve 8 to approx. 100 °C, e.g., using a hot air blower/heat gun with temperature control. Unscrew the spindle housing together with the grinder spindle using open-end spanner 12 by turning in anticlockwise direction, while counter-holding the spanner surfaces of the threaded sleeve 8 with open-end spanner 10.
Inserting an Extension
- Apply a drop of the provided Loctite 241 to the thread of the extension 9. Screw the thread of the extension into grinder spindle 4 and tighten with 20Nm .
- Pay attention that the toothing of the spindle is mounted tension-free.
- When mounting an additional extension, also apply a drop of Loctite 241 to the second extension and screw it onto the first one.
- Afterwards, apply a drop of the provided Loctite 241 to the thread of the threaded sleeve 8, screw on the extension and tighten with 20Nm .

Dust/Chip Extraction
Dusts from materials such as lead-containing coatings, some wood types, minerals and metal can be harmful to one's health. Touching or breathing-in the dusts can cause allergic reactions and/or lead to respiratory infections of the user or bystanders.
Certain dusts, such as oak or beech dust, are considered as carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.
- Provide for good ventilation of the working place.
- It is recommended to wear a P2 filter-class respirator. Observe the relevant regulations in your country for the materials to be worked.
▶ Prevent dust accumulation at the workplace. Dusts can easily ignite.
Connection to the Power Supply
For operation of the power tools, a frequency converter is required that generates three-phase current with a frequency according to that listed on the type plate.
Frequency converters are available in various sizes, with different frequencies, secondary voltages and rated outputs. The choice of the frequency converter depends on the power tools to be connected. When selecting a frequency converter, contact your Bosch-specialist shop for advice.
The machine is provided with a four meter long specialty cable without plug. To put it into operation, the specialty cable must be equipped with a four-pole CEE plug (identification colour green).
Additionally, the machine can be equipped with a commercially available motor protection switch for protection against overload. The adjustment range of the motor protection switch must cover the nominal current of the power tool (see "Technical Data"). The motor protection switch must react in less than one second.
Please observe the safety warnings and assembly instructions in the operating instructions of the motor protection switch!

English | 37
▶ Check grinding tools before using. The grinding tool must be mounted properly and be able to move freely. Carry out a test run for at least one minute with no load. Do not use damaged, out-of-centre or vibrating grinding tools. Damaged grinding tools can burst and cause injuries.
If the machine should unexpectedly stop operating even though the On/Off switch 6 is in the "On" position, set the On/Off switch to "Off". This will prevent uncontrolled restarting of the machine. Before restarting the machine, check the power supply (see "Connection to the Power Supply", page 36).
To save energy, only switch the power tool on when using it.
▶ Always connect the power tool to the frequency converter first, before connecting the frequency converter to the mains supply.
Switching the Frequency Converter On/Off
The frequency converter must be put into operation first before actuating the power tool.
For this, observe the operating instructions of the frequency converter.
Switching the Power Tool On/Off (Type 0 602 207 ..., 0 602 208 ..., 0 602 209 ..., 0 602 210 ..., 0 602 211 ..., 0 602 245 ...)
- To start the power tool, press the On/Off switch 6 forward and then down.
- To lock-on the pressed On/Off switch 6, push the On/Off switch 6 further forward.
- To switch off the power tool, release the On/Off switch 6, or when it is locked, briefly press the On/Off switch 6 and then release it.
Switching the Power Tool On/Off (Type0 602 238 ...)
- To switch on the power tool, press the On/Off switch 6 and keep it pressed during the working procedure.
- To lock the On/Off switch 6, press and hold the On/Off switch and push the locking lever 7 toward the front until it engages.

- When the On/Off switch 6 is locked-on, press it first and then release it. The locking lever 7 automatically disengages.
Switching the Power Tool On/Off
(Type 0 602 226 ..., 0 602 227 ..., 0 602 228 ..., 0 602 229 ..., 0 602 233 ...)
To switch on the machine, flip the On/Off switch 6 to position I.
To save energy, only switch the power tool on when using it. To switch off the machine, flip the On/Off switch 6 to position 0.
Working Advice
▶ Disconnect the power supply before making any adjustments, changing accessories, or placing the machine aside. This safety measure prevents accidental starting of the power tool.
▶ 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 accessory.
▶ Application tools can become very hot while working. Do not touch them before they have cooled down.
▶ Protect the abrasive wheels from impacts.
Working with the Straight Grinder
The choice of the application tools, such as grinding points or flap discs, depends on the application case and area. For support on choosing the appropriate grinding accessory, please contact your Bosch specialist shop.
Optimum grinding results are achieved when the grinding tool is moved uniformly back and forth with light pressure. Pressure that is too strong reduces the performance capability of the machine and causes the grinding tool to wear more quickly.
Grinding with Grinding Point
For grinding points, the grinding medium, e.g. corundum or silicone carbide, is formed and bond with suitable bonding agents and possibly with reinforcement inlays, thus representing a grinding and load-carrying unit. During operation, both the grinding and bonding agent are "used up" evenly, whereby the size of the grinding point gradually becomes smaller.
Grinding points are particularly suitable for precision mechanical work, mould making and for deburring metal. Due to the high circumferential speed, the workpiece is subject to high heat development.
Grinding with Grinding Discs
When grinding, the best working results are achieved when the grinding disc is applied as flat as possible. Move the machine back and forth applying moderate pressure. This ensures that the workpiece does not become too hot, and is not subject to discolouration and grooves.
Maintenance and Service
Maintenance and Cleaning
▶ Disconnect the power supply before making any adjustments, changing accessories, or placing the machine aside. This safety measure prevents accidental starting of the power tool.
For safe and proper working, always keep the machine and ventilation slots clean.
In extreme conditions, always use dust extraction as far as possible. Blow out ventilation slots frequently and install a portable residual current device (PRCD).
When working metals, conductive dust can settle in the interior of the power tool. The total insulation of the power tool can be impaired.
38 | English
▶ Regularly measure the no-load speed of the grinder spindle. When the measured value is more than 10 % above or below the specified no-load speed (see "Technical Data"), have the machine checked by an authorised service agent for Bosch power tools. When the no-load speed is too high, the application tool can break; when the no-load speed is too low, the working performance is reduced.
▶ Use only original cables! Before each use, check the power tool, cable and plug for possible damage. Cables and plugs may not be repaired, but must be exchanged in order to avoid danger.
▶ Have maintenance and repair work performed only by qualified specialists. In this manner, it can be ensured that the safety of the power tool is maintained.
Clean the connection sockets, couplers and plugs of the tool, after it has been disconnected from the mains supply, using a dry, lint-free cloth and remove dust and dirt particles.
Clean the gearbox after the first 150 running hours using a mild solvent. Follow the solvent manufacturers directions for use and disposal. Lubricate the gearbox using Bosch gearbox lube. Repeat the lubrication procedure every 300 hours after the initial gearbox service.
An authorized Bosch after-sales service agent will carry out this work quickly and reliably.
If the replacement of the supply cord is necessary, this has to be done by Bosch or an authorized Bosch service agent in order to avoid a safety hazard.
Please store and handle the accessory(-ies) carefully.
