Safety Notes
General Power Tool Safety Warnings
WARNING
When using electric tools basic safety precautions should always be followed to reduce the risk of fire, electric shock and personal injury including the following.
Read all these instructions before attempting to operate this product and save these instructions.
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.
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 Mitre Saws
▶ Never stand on the power tool. Serious injuries can occur when the power tool tips over or when inadvertently coming into contact with the saw blade.
▶ Make sure that the guard operates properly and that it can move freely. Never lock the guard in place when opened.
▶ Never remove cutting remainders, wood chips, etc. from the sawing area while the machine is running. Always guide the tool arm back to the neutral position first and then switch the machine off.
▶ Guide the saw blade against the workpiece only when the machine is switched on. Otherwise there is danger of kickback when the saw blade becomes wedged in the workpiece.
▶ Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery causing loss of control.
▶ Operate the power tool only when the work area to the workpiece is clear of any adjusting tools, wood chips, etc. Small pieces of wood or other objects that come in contact with the rotating saw blade can strike the operator with high speed.
- Keep the floor free of wood chips and material remainders. You could slip or trip.
▶ Always firmly clamp the piece to be worked. Do not saw workpieces that are too small to clamp. Otherwise, the clearance of your hand to the rotating saw blade is too small.
▶ Use the machine only for cutting the materials listed under Intended Use. Otherwise, the machine can be subject to overload.
If the saw blade should become jammed, switch the machine off and hold the workpiece until the saw blade comes to a complete stop. To prevent kickback, the workpiece may not be moved until after the machine has come to a complete stop. Correct the cause for the jamming of the saw blade before restarting the machine.
▶ Do not use dull, cracked, bent or damaged saw blades. Unsharpened or improperly set saw blades produce narrow kerf causing excessive friction, blade binding and kick-back.
▶ Always use blades with correct size and shape (diamond versus round) of arbour holes. Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.
▶ Do not use high speed steel (HSS) saw blades. Such saw blades can easily break.
▶ Do not touch the saw blade after working before it has cooled. The saw blade becomes very hot while working.
▶ Never operate the machine without the insert plate. Replace a defective insert plate. Without flawless insert plates, injuries are possible from the saw blade.
▶ Check the cable regularly and have a damaged cable repaired only through an authorised customer service agent for Bosch power tools. Replace damaged exten-
sion cables. This will ensure that the safety of the power tool is maintained.
▶ Store the machine in a safe manner when not being used. The storage location must be dry and lockable.
This prevents the machine from storage damage, and from being operated by untrained persons.
▶ Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
▶ Never leave the machine before it has come to a complete stop. Cutting tools that are still running can cause injuries.
▶ 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 authorised 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.
Products sold in AUS and NZ only: Use a residual current device (RCD) with a rated residual current of 30 mA or less.
Symbols
The following symbols can be important for the operation of your power tool. Please memorise the symbols and their meanings. The correct interpretation of the symbols helps you operate the power tool better and more safely.
Symbols and their meaning
▶ Keep hands away from the cutting area while the machine is running. Danger of injury when coming in contact with the saw blade.
▶ Wear a dust respirator.
▶ Wear safety goggles.
▶ Wear ear protectors. Exposure to noise can cause hearing loss.
14 | English
Symbols and their meaning

Profile strips/mouldings can be sawn in two different ways:
- Placed against the fence
- Lying flat on the saw table.
Always make trial cuts with the mitre angle setting first on scrap wood.

Checking and Adjusting the Basic Adjustment
To ensure precise cuts, the basic adjustment of the machine must be checked and adjusted as necessary after intensive use.
A certain level of experience and appropriate specialty tools are required for this.
A Bosch after-sales service station will handle this maintenance task quickly and reliably.
Setting the Standard Bevel Angle 0° (Vertical)
- Bring the power tool into the working position.
- Turn the saw table 30 to the 0^ detent 29. The lever 10 must be felt to engage in the detent.
Checking: (see figure Q1)
- Adjust an angle gauge to 90^ and position it on the saw table 30.
The leg of the angle gauge must be flush with the saw blade 34 over the complete length.
Adjusting: (see figure Q2)
- Loosen clamping lever 23.
- Push the stop 26 completely to the rear.
- Loosen the lock nut of the stop screw 53 using a commercial box-end or open-end spanner (size 13 mm).
- Screw the stop screw in or out until the leg of the angle gauge is flush with the saw blade over the complete length.
- Tighten clamping lever 23 again.
- Afterwards, retighten the lock nut of the stop screw 53 again. In case the angle indicator 25 is not in a line with the 0° mark of the scale 24 after the adjustment, loosen the screw 52 using a commercial cross-head screwdriver and align the angle indicator along the 0° mark.
Setting the Standard Bevel Angle 45° (Vertical)
- Bring the power tool into the working position.
- Turn the saw table 30 to the 0^ detent 29. The lever 10 must be felt to engage in the detent.
- Turn the stop 19 completely to the rear.
- Loosen clamping lever 23 and tilt the tool arm by handle 4 leftward to the stop (45°).
Checking: (see figure R1)
- Adjust an angle gauge to 45^ and position it on the saw table 30.
The leg of the angle gauge must be flush with the saw blade 34 over the complete length.
Adjusting: (see figure R2)
- Loosen the lock nut of the stop screw 54 using a commercial box-end or open-end spanner (size 13 mm).
- Screw the stop screw in or out until the leg of the angle gauge is flush with the saw blade over the complete length.
- Tightenclamajn.inglever 23ag

English | 21
In case the angle indicator 25 is not in a line with the 45^ mark of the scale 24, firstly check the 0^ setting for the bevel angle and the angle indicator again. Then repeat the adjustment of the 45^ bevel angle.
Aligning the Scale for Mitre Angles
- Bring the power tool into the working position.
- Turn the saw table 30 to the 0^ detent 29. The lever 10 must be felt to engage in the detent.
Checking: (see figure S1)
- Adjust an angle gauge to 90^ and position it between the fence 6 and the saw blade 34 on the saw table 30.
The leg of the angle gauge must be flush with the saw blade 34 over the complete length.
Adjusting: (see figure S2)
- Loosen all four set screws 55 with the hex key (4 mm) 17 and turn the saw table 30 together with the scale 13 until the leg of the angle gauge is flush with the saw blade over the complete length.
- Retighten the screws again.
When the angle indicator 12 is not in line with the 0° mark of scale 13 after adjusting, loosen screw 56 with a cross-head screwdriver and align the angle indicator alongside the 0° mark.
Transport (see figure T)
Before transporting the power tool, the following steps must be carried out:
- Guide the tool arm downward until the transport safety-lock 20 can be pushed completely inward.
- Slide the saw-table extensions 15 completely in and lock them in place (by pushing clamping lever 14 down).
- Adjust a 0^ bevel angle and tighten clamping lever 23.
- Turn saw table 30 rightward to the stop and tighten locking knob 9.
- Wind up the mains cable and tie it together with Velcro strap 57.
- Remove all accessories that cannot be mounted firmly to the power tool. If possible, place unused saw blades in an enclosed container for transport.
- Carry the machine by the transport handle 3 or hold it by the recessed handles 16 on the sides of the saw table.
▶ When transporting the power tool, use only the transport devices and never use the protective devices.
Maintenance and Service
Maintenance and Cleaning
▶ Before any work on the machine itself, pull the mains plug.
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.
Cleaning
For safe and proper working, always keep the power tool and its ventilation slots clean.
The retracting blade guard must always be able to move freely and retract automatically. Therefore, always keep the area around the retracting blade guard clean.
Remove dust and chips after each working procedure by blowing out with compressed air or with a brush.
Clean the roller 35 regularly.
