Safety instructions

General Power Tool Safety Warnings
WARNING
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.
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 the 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 that may ignite 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 the 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 the 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.
  The 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.
  The 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 innate- 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 hats, 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.
  u If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of dust collection can reduce dust-related hazards.

• Do not let familiarity gained from the 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 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 toward 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 at 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 miter saw is mounted or placed on a level, firm work surface before use. A level and firm work surface reduce the risk of the miter saw becoming unstable.
• Plan your work. Every time you change the bevel or miter 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 tabletop. Workpieces longer or wider than the miter 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 miter 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 miter saw.
• After finishing the cut, release the switch, hold the saw head down, and wait for the blade to stop before 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.
• 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 kerfs 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 the correct size and shape (diamond versus round) of arbor holes. Saw blades that do not match the mounting hardware of the saw will run off-center, causing a 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.

For a quick and precise setting of commonly used miter angles, detents (14) are provided on the saw table:

• Loosen the locking knob (11) if it is tightened.
• Pull the lever (12) and rotate the saw table (33) left or right to the required detent.
• Release the lever again. The lever must be felt to engage in the detent.
• Retighten the locking knob (11).

Setting any miter angle (see figure I)
The miter angle can be set between 52° (left side) and 60° (right side).

• Loosen the locking knob (11) if it is tightened.

• Pull the lever (12) and at the same time push the miter detent override (10) downward at the front.
  This locks the lever (12) and the saw table can move freely.

• Turn the saw table (33) left or right by the locking knob until the angle indicator (51) shows the required miter angle.

• Retighten the locking knob (11).

• To loosen the lever (12) again (for setting standard miter angles), pull the lever upwards.
  The miter detent override (10) springs back into its original position and the lever (12) can click back into the detents (14).

Adjusting vertical miter angles
The bevel angle can be set between 47° (left side) and 47° (right side).
For a quick and precise setting of frequently used bevel angles, stops have been provided for the angles 0°, 22.5°, 45° and 47°.

Setting the left-hand bevel angle range (45° to 0°)

• Pull the left-hand adjustable fence (7) all the way out.
• Loosen the clamping handle (13).
• Use the handle (3) to swivel the gliding arm (23) to the left until the angle indicator (28) shows the required bevel angle.
• Hold the gliding arm (23) in this position and retighten the clamping handle (13).

The clamping force of the clamping handle must hold the gliding arm securely in place at any bevel angle.

Setting the Right-hand Bevel Angle Range (0° to 45°) (see figure J)

• Pull the right-hand adjustable fence (7) all the way out.
• Loosen the clamping handle (13).
• Use the handle (3) to tilt the gliding arm (23) slightly to the left from the 0° position and turn the rotary knob (32) until the required bevel angle range is shown.
• Use the handle (3) to swivel the gliding arm (23) to the right until the angle indicator (21) shows the required bevel angle.
• Hold the gliding arm (23) in this position and retighten the clamping handle (13).
  The clamping force of the clamping handle must hold the gliding arm securely in place at any bevel angle.

Setting the Standard 0° bevel angle
To enable the standard 0° bevel angle to be reset easily, the rotary knob (32) engages in the lefthand bevel angle range.

• Swivel the gliding arm (23) from the right to the 0° position.

Setting the entire bevel angle range (–47° to +47°)

• Pull both adjustable fences (7) all the way out.
• Loosen the clamping handle (13).
• Use the handle (3) to tilt the gliding arm (23) slightly to the left from the 0° position and turn the rotary knob (32) until the required bevel angle range is shown.
• Use the handle (3) to swivel the gliding arm (23) to the left or right until the angle indicator (28) or (21) shows the required bevel angle.
• Hold the gliding arm (23) in this position and retighten the clamping handle (13).

The clamping force of the clamping handle must hold the gliding arm securely in place at any bevel angle.

Setting the Standard 22.5° Bevel Angle (see figure K)
Pull the adjustment knob (29) all the way out and turn it 90°.
Then use the handle (3) to swivel the gliding arm (23) until you hear the gliding arm engage.

Start-up

▶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.
Switching on (see figure L)

• To switch on the power tool, first, slide the lock-off button (4) to the middle and then press and hold the on/ off switch (52).
  Note: For safety reasons, the on/off switch (52) cannot be locked; it must remain pressed during the entire operation.

Switching off

• To switch off, release the on/off switch (52).

Starting current limitation
The electronic starting current limitation feature restricts the power of the power tool when it is switched on and enables operation using a 16 A fuse.
Note: If the power tool runs at full speed immediately after being switched on, this means that the starting current limitation has failed. The power tool must be sent to the after-sales service without delay. For addresses, see: After-sales service and advice on using products.

Practical advice

General sewing instructions
▶ Always tighten the locking knob (11) and the clamping handle (13) firmly before sawing. Otherwise, the saw blade can become wedged in the workpiece.
▶ Always tighten the locking knob (11) and the clamping lever 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 that are permitted within the scope of the intended use.
Do not see 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 M)
▶ 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 kickbacks.

• 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.

Replacing the Insert Plates (see figure P)
The red insert plates (9) can become worn after prolonged use of the power tool.
Replace defective insert plates.

• Bring the power tool into the work position.
• Loosen the screws (53) using the hex key (4 mm) (30) and remove the old insert plates.
• Insert the new right-hand insert plate.
• Screw the insert plate as far as possible to the right with the screws (53) so that the saw blade does not come into contact with the insert plate over the entire length of the possible slide motion.
• Repeat the work steps in the same manner for the lefthand insert plate.

Permissible workpiece dimensions
Maximum workpiece dimensions:

Minimum workpiece dimensions (= all workpieces that can be secured left or right of the saw blade using the supplied screw clamps (19)): 145 x 306 mm (length x width) Maximum cutting depth (0°/0°): 100 mm

Sawing

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

• Slide the gliding arm (23) all the way back and secure it in this position.
  Make sure that the depth stop (25) is pressed all the way in and that the adjusting screw (24) fits through the recess without touching the depth stop when moving the gliding arm.

• Firmly clamp the workpiece as appropriate for its dimensions.

• Set the required miter and/or bevel angle as necessary.

• Switch on the power tool.

• Slowly guide the gliding arm (23) downwards using the handle (3).

• Saw through the workpiece applying uniform feed.

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

• Slowly guide the gliding arm (23) upwards.

Sawing with Slide Movement (see figure O)
▶ Maintain a firm grip on the handle before switching the power tool on and during the entire sawing process. Ensure that the movement of the gliding arm is controlled during sawing. The glide arm is very easy to move and a moment of inattention could result in serious injury.

• Unlock the gliding arm (23).
  Check if the complete glide mechanism is operative by sliding the gliding arm (23) back and forth.

• Firmly clamp the workpiece as appropriate for its dimensions.

• Set the required miter and/or bevel angle as necessary.

• Pull the gliding arm (23) away from the fence (8) by the handle (3) until the saw blade is in front of the workpiece.

• Switch on the power tool.

• Slowly guide the gliding arm (23) downwards using the handle (3).

• Now push the gliding arm (23) towards the fence (8) 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 gliding arm (23) upwards.

Adjusting the Depth Stop (Sawing the Groove) (see figure Q)
The depth stop needs to be adjusted if you wish to saw a groove or use a spacer.
– Swivel the depth stop (25) outwards.
– Use the handle (3) to swivel the gliding arm (23) into the required position.
– Turn the adjusting screw (24) until the end of the screw touches the depth stop (25).
– Slowly guide the gliding arm (23) upwards.
Special workpieces
When sawing curved or round workpieces, these must be specially 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.

Working on moldings

Moldings can be sawn in two different ways:

Furthermore, you can cut with or without the slide movement depending on the width of the molding.
Always check the set miter 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.

• Wind up the mains cable and tie it together with the hook-and-loop strap (62).
• 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 holding it by the recessed handles (17) on the sides of the saw table.
  ▶ Use only the transport fixtures to transport the power tool. Never carry the power tool by the protective devices, the gliding arm (23), or the handle (3).

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 center that is authorized to repair Bosch power tools.
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.
Always remove dust and chips after working by blowing out with compressed air or using a brush.

• Clean the guide roller (20) and the gliding arm (23) regularly.
