Safety instructions

General Power Tool Safety Warnings

WARNING

Read all safety warnings, instructions, illustrations and specifica-

tions provided with this power tool. Failure to follow all instructions listed below 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 or 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 inatten-

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 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 and clothing 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.
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.

Safety Warnings for Mitre Saws

• Mitre saws are intended to cut wood or wood-like products, they cannot be used with abrasive cut-off wheels for cutting ferrous material such as bars, rods, studs, etc. Abrasive dust causes moving parts such as the lower guard to jam. Sparks from abrasive cutting will burn the lower guard, the kerf insert and other plastic parts.
  ▶ Use clamps to support the workpiece whenever possible. If supporting the workpiece by hand, you must always keep your hand at least 100 mm from either side of the saw blade. Do not use this saw to cut pieces that are too small to be securely clamped or held by hand. If your hand is placed too close to the saw blade, there is an increased risk of injury from blade contact.
  The workpiece must be stationary and clamped or held against both the fence and the table. Do not feed the workpiece into the blade or cut "freehand" in any way. Unrestrained or moving workpieces could be thrown at high speeds, causing injury.
  ▶ Push the saw through the workpiece. Do not pull the saw through the workpiece. To make a cut, raise the saw head and pull it out over the workpiece without cutting, start the motor, press the saw head down and push the saw through the workpiece. Cutting on the pull stroke is likely to cause the saw blade to climb on top of the workpiece and violently throw the blade assembly towards the operator.
  ▶ Never cross your hand over the intended line of cutting either in front or behind the saw blade. Supporting the workpiece “cross handed” i.e. holding the workpiece to the right of the saw blade with your left hand or vice versa is very dangerous.
  ▶ Do not reach behind the fence with either hand closer than 100 mm from either side of the saw blade, to remove wood scraps, or for any other reason while the blade is spinning. The proximity of the spinning saw blade to your hand may not be obvious and you may be seriously injured.

Inspect your workpiece before cutting. If the workpiece is bowed or warped, clamp it with the outside bowed face toward the fence. Always make certain that there is no gap between the workpiece, fence and table along the line of the cut. Bent or warped workpieces can twist or shift and may cause binding on the spinning saw blade while cutting. There should be no nails or foreign objects in the workpiece.
Do not use the saw until the table is clear of all tools, wood scraps, etc., except for the workpiece. Small debris or loose pieces of wood or other objects that contact the revolving blade can be thrown with high speed.
▶ Cut only one workpiece at a time. Stacked multiple workpieces cannot be adequately clamped or braced and may bind on the blade or shift during cutting.
▶ Ensure the mitre saw is mounted or placed on a level, firm work surface before use. A level and firm work surface reduces the risk of the mitre saw becoming unstable.
Plan your work. Every time you change the bevel or mitre angle setting, make sure the adjustable fence is set correctly to support the workpiece and will not interfere with the blade or the guarding system. Without turning the tool "ON" and with no workpiece on the table, move the saw blade through a complete simulated cut to assure there will be no interference or danger of cutting the fence.
▶ Provide adequate support such as table extensions, saw horses, etc. for a workpiece that is wider or longer than the table top. Workpieces longer or wider than the mitre saw table can tip if not securely supported. If the cut-off piece or workpiece tips, it can lift the lower guard or be thrown by the spinning blade.
▶ Do not use another person as a substitute for a table extension or as additional support. Unstable support for the workpiece can cause the blade to bind or the workpiece to shift during the cutting operation pulling you and the helper into the spinning blade.
The cut-off piece must not be jammed or pressed by any means against the spinning saw blade. If confined, i.e. using length stops, the cut-off piece could get wedged against the blade and thrown violently.
▶ Always use a clamp or a fixture designed to properly support round material such as rods or tubing. Rods have a tendency to roll while being cut, causing the blade to "bite" and pull the work with your hand into the blade.
▶ Let the blade reach full speed before contacting the workpiece. This will reduce the risk of the workpiece being thrown.
If the workpiece or blade becomes jammed, turn the mitre saw off. Wait for all moving parts to stop and disconnect the plug from the power source and/or remove the battery pack. Then work to free the jammed material. Continued sawing with a jammed workpiece could cause loss of control or damage to the mitre saw.
▶ After finishing the cut, release the switch, hold the saw head down and wait for the blade to stop before

16 | English

removing the cut-off piece. Reaching with your hand near the coasting blade is dangerous.

▶ Hold the handle firmly when making an incomplete cut or when releasing the switch before the saw head is completely in the down position. The braking action of the saw may cause the saw head to be suddenly pulled downward, causing a risk of injury.
▶ Do not let go of the handle once the saw head has reached the lowest position. Always guide the saw head back to the top position by hand. There is a risk of injury if the saw head moves in an uncontrolled manner.
- Keep your work area clean. Material mixtures are particularly hazardous. Light metal dust may catch fire or explode.
▶ 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 kickback.
▶ Do not use saw blades made from high speed steel (HSS). Such saw blades can easily break.
▶ Always use saw blades with correct size and shape (diamond versus round) of arbour holes. Saw blades that do not match the mounting hardware of the saw will run off-centre, causing loss of control.
▶ Never remove cuttings, wood chips, etc. from the cutting area while the power tool is running. Always guide the tool arm back to the neutral position first and then switch the power tool off.
▶ Do not touch the saw blade after working before it has cooled. The saw blade becomes very hot while working.

Dust/Chip Extraction

The dust from materials such as lead paint, some types of wood, 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 dusts, such as oak or beech dust, are classified as carcinogenic, especially in conjunction with wood treatment additives (chromate, wood preservative). Materials containing asbestos may only be machined by specialists.

- Use a dust extraction system that is suitable for the material wherever possible.

- Provide good ventilation at the workplace.

- It is advisable to wear a P2 filter class breathing mask.

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

- Avoid dust accumulation at the workplace. Dust can easily ignite.

The dust/chip extraction system can be blocked by dust, chips or fragments of the workpiece.

• Switch the power tool off and pull the mains plug out of the socket.
• Wait until the saw blade has come to a complete stop.
• Determine the cause of the blockage and eliminate it.

Self-generated dust extraction (see figure D)

For basic chip collection, use the dust bag (43) provided.

- Attach the dust bag (43) to the chip ejector (36).

During sawing, the dust bag must not come into contact with moving tool components.

Always empty the dust bag in good time.

▶ Check and clean the dust bag each time after using.
▶ When sawing aluminium, remove the dust bag to avoid the risk of fire.

External dust extraction (see figure E)

You can also attach a dust extraction hose (35 mm diameter) to the extraction adapter (42) for extraction.

• Attach the dust extraction adapter (42) to the chip ejector with a twisting motion until it engages above the chip ejector (36) holding ring.
• Connect the dust extraction hose to the extraction adapter (42).

The dust extractor must be suitable for the material being worked.

When extracting dry dust that is especially detrimental to health or carcinogenic, use a special dust extractor.

- Release the clamping wheel (38).

Standard bevel angle 0^ :

- Swivel the tool arm slightly to the left to the 0° position and then to the right until you feel it click into place in the 0° position.

- Retighten the clamping wheel (38).

Standard bevel angle 33.9° and 22.5°:

- Release the locking lever (21) upwards.

- Swivel the tool arm left or right until the angle indicator (52)/(50) shows the required bevel angle. The tool arm must engage securely in place.

- Retighten the clamping wheel (38).

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 power tool.

Switching on (see figure N)

- To start the power tool, first push in the lock-off button (5). Then press the on/off switch (34) all the way in and keep it pressed.

Note: For safety reasons, the on/off switch (34) cannot be locked; it must remain pressed during the entire operation.

Switching off

- To switch off, release the on/off switch (34).

Sawing

General sawing instructions

▶ Always tighten the locking knob (11) and the clamping wheel (38) firmly before sawing. Otherwise the saw blade can become wedged in the workpiece.

For all cuts, it must first be ensured that the saw blade at no time can come in contact with the fence, screw clamps or other machine parts. Remove any mounted auxiliary stops or adjust them accordingly.

Protect the saw blade against impact and shock. Do not subject the saw blade to lateral pressure. Only saw materials which are permitted within the scope of the intended use.

Do not saw warped/bent workpieces. The workpiece must always have a straight edge to face against the fence.

The free end of long and heavy workpieces must have something placed underneath it or be supported.

Make sure that the retracting blade guard operates properly and that it can move freely. The retracting blade guard must open when the tool arm is guided downwards. When the tool arm is guided upwards, the retracting blade guard must close again over the saw blade and lock in the uppermost position of the tool arm.

Position of the operator (see figure O)

▶ Do not stand in line with the saw blade in front of the power tool. Always stand to the side of the saw blade. This protects your body against possible kickback.

- Keep hands, fingers and arms away from the rotating saw blade.

- Do not reach one hand across the other when in front of the tool arm.

Sawing with slide movement

- For cuts made using the slide device (2) (wide workpieces), loosen the locking screw (1) if it is tightened.

- Set the required mitre and/or bevel angle as necessary.

- Press the workpiece firmly against the fences (17) and (18).

- Firmly clamp the workpiece as appropriate for its dimensions.

- Pull the tool arm away from the fence (17) until the saw blade is in front of the workpiece.

- Switch the power tool on.

- Slowly guide the tool arm downwards using the handle (4).

- Now push the tool arm towards the fences (17) and (18) and saw through the workpiece with uniform feed.

- Switch off the power tool and wait until the saw blade has come to a complete stop.

- Slowly guide the tool arm upwards.

Sawing without slide movement (cutting off) (see figure P)

- For cuts without slide movement (small workpieces), loosen the locking screw (1) if it is tightened. Push the tool arm all the way towards the fence (17) and retighten the locking screw (1).

- Set the required mitre and/or bevel angle as necessary.

- Press the workpiece firmly against the fences (17) and (18).

- Firmly clamp the workpiece as appropriate for its dimensions.

- Switch the power tool on.

- Slowly guide the tool arm downwards using the handle (4).

- Saw through the workpiece applying uniform feed.

22 | English

• Switch off the power tool and wait until the saw blade has come to a complete stop.
• Slowly guide the tool arm upwards.

Practical advice

Marking the Cutting Line (see figure Q)

The worklight improves visibility in the immediate work area and also indicates the cutting line of the saw blade. This allows for exact positioning of the workpiece for sawing, without having to open the retracting blade guard.

• Mark the required cutting line on the workpiece.
• Switch on the worklight with the switch (35).
• Guide the tool arm down in front of the workpiece. The saw blade's shadow will appear on the workpiece. This shadow line indicates the material that will be removed by the saw blade during cutting.
• Align your mark on the workpiece with the shadow line.

Permissible workpiece dimensions

Maximum workpiece dimensions:

Mitre angle Bevel angle Height x width [mm]

0° 0° 105 x 340

45° 0° 105 x 245

0° 45° (left) 70 x 340

45° 45° (left) 70 x 245

0° 45° (right) 48 x 340

45° 45° (right) 48 x 245

Maximum cutting depth (0°/0°): 105 mm

Sawing workpieces of the same length (see figure R)

The left or right length stop (29) can be used for easily sawing workpieces of the same length.

• Turn the length stop (29) upwards.
• Set the saw table extension (15) to the required workpiece length.

Adjusting the depth stop (sawing the groove) (see figure S)

The depth stop needs to be adjusted if you wish to saw a groove.

• Swivel the depth stop (25) outwards.
• Swivel the tool arm by the handle (4) into the required position.
• Turn the adjusting screw (26) until the end of the screw touches the depth stop (25).
• Slowly guide the tool arm upwards.

Special workpieces

When sawing curved or round workpieces, these must be especially secured against slipping. At the cutting line, there should be no gap between the workpiece, fence and saw table.

If necessary, you will need to manufacture special fixtures.

Replacing insert plates (see figure T)

The insert plate (9) can become worn after long use of the power tool.

Replace a defective insert plate.

• Bring the power tool into the work position.
• Unscrew the screws (54) using a commercially available cross-headed screwdriver and remove the old insert plate (9).
• Insert the new insert plate and screw the screws (54) in tight again.

Working on mouldings

Mouldings can be sawn in two different ways:

Positioning of workpiece	Base moulding Crown moulding
- Placed against the fence
- Lying flat on the saw table

Furthermore, you can cut with or without the slide movement depending on the width of the moulding.

Always check the set mitre and/or bevel angle first by making trial cuts in scrap wood.

Checking and Adjusting the Basic Settings

To ensure precise cuts, the basic settings of the power tool must be checked and adjusted as necessary after intensive use.

Experience and suitable special tools are required for this.

A Bosch after-sales service point will handle this work quickly and reliably.

Aligning the fence

• Bring the power tool into the transport position.
• Loosen the locking knob (11) if it is tightened.
• Push the lock button (10) down and turn the saw table (32) to the 0° detent (14).
• Release the lock button (10) again. The saw table must be heard to click into the detent.
• Remove the adjustable fences (18).

Checking (see figure U1)

- Position the set square (55) with the 90^ angle flush with the saw blade (46) between the fence (17) and the saw blade on the saw table (32).

The leg of the set square must be flush with the fence along its entire length.

Setting (see figure U2)

• Loosen all hex socket screws (56) with the hex key (27) provided.
• Rotate the fence (17) until the set square is flush along its entire length.

- Retighten the screws.

Aligning the Angle Indicator (Vertical) (see figure V)

- Swivel the tool arm slightly to the left to the 0^ position and then to the right until you feel it click into place in the 0^ position.

Checking

The angle indicators (50) and (52) must be in line with the 0^ marks on the scale (51).

Setting

• Undo the screws (57) with a cross-headed screwdriver and align the angle indicators along the respective 0^ mark.
• Retighten the screws.

Aligning the mitre angle indicator (see figure W)

• Bring the power tool into the work position.
• Turn the saw table (32) to the 0^ detent (14). The lever must be felt to engage in the detent.

Checking

The angle indicator(13) must be in line with the 0^ mark of the scale (33).

Setting

• Loosen the screw (58) using a cross-headed screwdriver and align the angle indicator along the 0^ mark.
• Retighten the screw.

Transporting the Power Tool (see figure X)

Before transporting the power tool, the following steps must be carried out:

• Loosen the locking screw (1) if it is tightened. Pull the tool arm fully forwards and retighten the locking screw.
• Make sure that the depth stop (25) is pressed all the way in and that the adjusting screw (26) fits through the recess without touching the depth stop when moving the tool arm.
• Bring the power tool into the transport position.
• Remove all accessories that cannot be securely fitted to the power tool. If possible, transport unused saw blades in an enclosed container.
• Carry the power tool by the transport handle (3) or hold it by the recessed handles (30) on the sides of the saw table.

▶ Only use the transport devices to transport the power tool and never the protective devices or workpiece supports.

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.

The retracting blade guard (7) 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.

Always remove dust and chips after working by blowing out with compressed air or using a brush.

Clean the guide roller (22) regularly.
