tion while operating power tools may result in serious personal injury.

Use personal protective equipment. Always wear eye protection. Protective equipment such as a 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 a power source and/or battery pack, picking up, or carrying the tool. Carrying power tools with your finger on the switch or energizing 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 jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry, 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. Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

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 remove the battery pack, if detachable, 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 and accessories. 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.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

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.

Cut-off machine safety warnings

Position yourself and bystanders away from the plane of the rotating wheel. The guard helps to protect the operator from broken wheel fragments and accidental contact with wheel. Use only bonded reinforced cut-off wheels for your power tool. Just because an accessory can be attached to your power tool, it 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. Wheels must be used only for recommended applications. For example: do not grind with the side of a cutoff 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 diameter for your selected wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage. 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 and flanges must properly fit the spindle of the power tool. Wheels and flanges with arbour 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 damaged wheels. Before each use, inspect the wheels for chips and cracks. If the power tool or wheel is dropped, inspect for damage or install an undamaged wheel. After inspecting and installing the wheel, position yourself and bystanders away from the plane of the rotating wheel and run the power tool at maximum no load speed for one minute. Damaged wheels will normally break apart during this test time.

Wear personal protective equipment. Depending on the application, use a face shield, safety goggles, or safety glasses. As appropriate, wear a dust mask, hearing protectors, gloves, and a 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 filtering 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 the workpiece or of a broken wheel may fly away and cause injury beyond the immediate area of operation. Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning wheel. Regularly clean the power tool's air vents. The motor's fan can draw dust inside the housing, and excessive accumulation of powdered metal may cause electrical hazards. Do not operate the power tool near flammable materials. Do not operate the power tool while it is placed on a combustible surface such as wood. 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. Pinching or snagging causes rapid stalling of the rotating wheel, which in turn causes the uncontrolled cutting unit to be forced upwards toward the operator.

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. 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 upward kickback forces if proper precautions are taken. Do not position your body in line with the rotating wheel. If kickback occurs, it will propel the cutting unit upwards toward the operator. Do not attach a saw chain, woodcarving blade, segmented diamond wheel with a peripheral gap greater than 10 mm, or toothed saw blade. Such blades create frequent kickback and loss of control. Do not "jam" the wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and sus

ceptibility to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage.

When the wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold the cutting unit motionless until the wheel comes to a complete stop. Never attempt to remove the 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 re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece. Support 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.

Additional safety information

Store the power tool safely when it is not in use. The storage location must be dry and lockable. This prevents the power tool from storage damage, and from being operated by untrained persons. Always firmly clamp the workpiece into place. Do not carry out work on workpieces that are too small to be clamped. Otherwise, the distance between your hand and the rotating cutting disc will be too small. Check the cable regularly and have a damaged cable repaired only by an authorised customer service agent for Bosch power tools. Replace damaged extension cables. This will ensure that the safety of the power tool is maintained. Never stand on the power tool. Serious injuries may occur if the power tool tips over or if you inadvertently come into contact with the saw blade. Always use the protective guard. The protective guard protects users from any parts that break off from the cutting disc and prevents unintentional contact with the cutting disc. Do not brake the cutting disc to a stop by applying side pressure after switching the power tool off. The cutting disc can be damaged, break or cause kickback. Never leave the tool unattended before it has come to a complete stop. Cutting tools that are still running can cause injuries.

Start-up

Pay attention to the mains voltage. The voltage of the power source must match the voltage specified on the rating plate of the charger. Chargers marked 230 V can also be operated at 220 V. ▶ Products that are only sold in AUS and NZ: Use a residual current device (RCD) with a nominal residual current of 30 mA or less. - Check the cutting disc before using it. The cutting disc must be fitted properly and be able to rotate freely. Carry out a test run for at least 30 seconds with no load. Do not use cutting discs that are damaged, run untrue or vibrate during use. Damaged cutting discs can shatter and cause injuries.

The dust from materials such as lead paint, minerals and metal can be harmful to human health. Touching or breathing in this dust can trigger allergic reactions and/or cause respiratory illnesses in the user or in people in the near vicinity.

Certain kinds of metal dust are hazardous, especially in combination with alloys such as zinc, aluminium or chrome. Materials containing asbestos may only be machined by specialists.

• Provide good ventilation at the workplace.
• It is advisable to wear a P2 filter class breathing mask.

The regulations on the materials being machined that apply in the country of use must be observed.

Practical advice

General advice on using cutting discs

Do not touch the cutting disc after use until it has cooled. The cutting disc becomes very hot during use. Make sure that the spark guard plate (19) is fitted properly. Flying sparks are created when sanding metals.

Protect the cutting disc against impact, shock and grease. Do not subject the cutting disc to lateral pressure.

Do not load the power tool so heavily that it comes to a stop. Excessive feed significantly reduces the performance of the power tool and the service life of the cutting disc.

Only use cutting discs that are suitable for the material being machined.

Maintenance and Service

Maintenance and Cleaning

Pull the plug out of the socket before carrying out any work on the power tool. To ensure safe and efficient operation, always keep the power tool and the ventilation slots clean.

In order to avoid safety hazards, if the power supply cord needs to be replaced, this must be done by Bosch or by an after-sales service centre that is authorised to repair Bosch power tools.

Clean the air vents on your power tool regularly. The motor's fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards. In extreme conditions, always use a dust extractor if possible. Blow out ventilation slots frequently and install a residual current device (RCD) upstream. When machining metals, conductive dust can settle inside the power tool, which can affect its protective insulation. Have maintenance and repair work performed exclusively by a qualified specialist. This will ensure that the safety of the power tool is maintained.

The retracting blade guard must always be able to move freely and retract automatically. It is therefore important to keep the area around the retracting blade guard clean at all times.

Additional warning symbols

Store the machine safely when not in use. Store the machine in a dry place and it can be locked. This prevents the machine from being damaged during storage and prevents untrained persons from operating it. Do not cut workpieces that are too small to be clamped. Do not cut workpieces that cannot be clamped. Otherwise, the distance between your hand and the rotating cutting disc is too small. Check the power cord regularly and have a damaged power cord repaired only by an authorized Bosch power tool service center. Replace a damaged extension cord. This ensures that the safety of the machine is maintained. Serious injury can occur if the power tool is tilted or if you accidentally touch the blade. Ensure that the blade guard works properly and can move freely. Always use the protective cover. The blade guard protects the user from fragments of the cutting disc or accidental contact with the cutting disc. Do not brake the cutting disc to a stop by applying pressure to the side of the blade after switching off. The cutting disc can be damaged, break, or lead to kickback. Never leave the machine before it has come to a complete stop. Cutting tools that are still running can cause injury.

Symbols

The following symbols may convey the meaning of how to use your cordless power tool. Please note the symbols and their meanings. Understanding the symbols will help you use the machine better and more safely.

-Angle grinder with mounted cutting disc

• Hex key (12)

Note: Check the power tool for any damage.

Before using the machine, carefully check that all protective devices or slightly damaged parts function properly and in accordance with the regulations. All slightly damaged parts must be carefully checked to ensure perfect operation of the tool. All parts must be correctly installed and all conditions must be met correctly and sufficiently to ensure perfect operation.

Damaged protective devices and parts must be replaced immediately through an authorized warranty and maintenance center.

Fixed or flexible mounting

To ensure safe control, the machine must be mounted on a flat and stable surface (e.g., workbench) before use.

Mounting on a work surface (see Figure A)

-Secure the power tool with suitable mounting screws onto the work surface. The holes for this purpose are provided (11).

Unlocking the Machine (Operating Position)

• Press the tool down slightly at the handle position (3) to release the transport lock (15). -Pull the transport lock (15) completely outwards. -Lift the machine head slowly.

Caution: When working, be aware that the safety transport device must not be pressed in, otherwise the saw head may not be able to be swiveled to the desired depth.

Machine Safety Lock (Transport Position)

-Pull the saw head down until the safety lock for transport (15) is fully engaged.

Other transport instructions (see, Transport Page 60).

Adjusting the miter angle (see Figure D)

The miter angle can be adjusted within a range from 0° to 45°.

Important adjustment values are marked with corresponding symbols on the angle stop (7). The 0° and 45° positions can be ensured through the corresponding end stop.

• Loosen the locking screws (14) of the angle stop using the supplied hex key (12) (8 mm). -Set the desired angle and tighten both locking screws (14).

Moving the angle stop (see Figure D-E)

You can move the angle stop (7) backwards if you want to cut workpieces wider than 140 mm.

Loosen the locking screws (14) using the supplied hex key (12) (8 mm). -Move the angle stop (7) to the desired distance by one or two holes. -Set the desired angle and tighten both locking screws (14).

Securing the workpiece (see Figure E)

To ensure maximum work safety, the workpiece must always be clamped securely.

Otherwise, the distance from your hand to the rotating saw blade is too small.

Long workpieces must be supported or padded at the free end.

Place the workpiece (7) on the base plate. Place the clamping lever (8) on the workpiece and secure the workpiece by tightening the clamping lever (10).

Removing the Workpiece

Loosen the clamping lever (10). Fold down the quick-release lever (9) and remove the clamping lever (8) from the workpiece.

Starting Operation

Observe the correct voltage! The voltage of the power source must match the specifications on the nameplate of the battery charger. Charging devices rated 230 V can also be operated at 220 V. Check the cutting disc before use. The cutting disc must be installed correctly and move freely. Run the machine without load for at least 30 seconds. Do not use damaged, eccentric, or loose cutting discs. A damaged cutting disc may shatter and cause injury.

Dust from materials such as lead-containing paint, minerals (e.g., stone) or metals can be hazardous to human health. Touching or inhaling this dust can cause allergic reactions and/or respiratory infections in the user or bystanders.

Certain types of dust are considered hazardous, especially those related to alloys such as zinc, aluminum, or chromium. Only professionals should machine materials containing asbestos.

Ensure good ventilation of the work area. It is recommended to wear a respirator with a P2 filter.

Comply with the national regulations of your country regarding the type of material being machined.

The cutting disc may become clogged with dust, debris, or product fragments at the opening of the base plate (13).

Switch off the machine and unplug the power cord from the outlet. Wait until the cutting disc has completely stopped rotating. Tilt the machine backward so that any debris from the workpiece can fall out through the opening designed for this purpose.

If necessary, use a suitable tool to remove all debris from the workpiece.

Avoid accumulation of debris at the work area. Debris can easily catch fire.

Operator's stance (see Figure F)

Do not stand directly in front of the cutting disc, but always stand to the side of it. This measure provides better protection for your body and prevents the risk of debris flying out if the cutting disc breaks.

Press (see Figure G)

• To turn on the tool, press the On/Off switch (2) and hold it.
• To lock the On/Off switch (2), press the lock button (1).
• To turn off the tool, release the On/Off switch (2). When the switch is locked, press it fully until the switch lock is released, then release the switch.

Operating Instructions

General Safety Instructions for Cutting

Do not touch the cutting disc immediately after operation, until it has cooled down. The cutting disc becomes very hot during operation. Ensure that the spark guard (19) is correctly installed. When cutting metal, sparks will fly out.

Protect the cutting disc from impacts, drops, and shocks. Do not subject the cutting disc to lateral pressure.

Do not overload the power tool beyond its intended capacity.

Overloading significantly reduces the machine's performance and shortens the cutting disc's lifespan.

Only use cutting discs suitable for the material being cut.
