General Power Tool Safety Warnings

WARNING
Read all safety warnings, instruc-tions, illustrations and specifications provided with this power tool. Failure to follow all in-structions 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 inattention while operating power tools may result in serious per-sonal 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 in-juries.
• 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 en-ergising power tools that have the switch on invites acci-dents.
• 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 in-jury.
• 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 jew-ellery. 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 ex-traction and collection facilities, ensure these are con-nected and properly used. Use of dust collection can re-duce 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 in-jury 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 de-signed.
• 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 re-move the battery pack, if detachable, from the power tool before making any adjustments, changing ac-cessories, 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 mis-alignment 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 main-tained 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 ac-count the working conditions and the work to be per-formed. 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.

Battery tool use and care

• Recharge only with the charger specified by the manu-facturer. A charger that is suitable for one type of bat-tery pack may create a risk of fire when used with another battery pack.
• Use power tools only with specifically designated bat-tery packs. Use of any other battery packs may create a risk of injury and fire.
• When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally oc-curs, flush with water. If liquid contacts eyes, addi-tionally seek medical help. Liquid ejected from the bat-tery may cause irritation or burns.
• Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
• Do not expose a battery pack or tool to fire or excess-ive temperature. Exposure to fire or temperature above 130°C may cause explosion.
• Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

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.
• Never service damaged battery packs. Service of bat-tery packs should only be performed by the manufacturer or authorized service providers.

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 pos-sible. 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 cut-ting 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 re-move 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 work-piece 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 work-pieces 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 con-tact 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 sur-face 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 in-terfere 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 be-ing 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 re-move 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 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 partic-ularly hazardous. Light metal dust may catch fire or ex-plode.
• 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 cut-ting 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.
• In case of damage and improper use of the battery, va-pours may be emitted. The battery can set alight or ex-plode. Ensure the area is well ventilated and seek medical attention should you experience any adverse effects. The vapours may irritate the respiratory system.
• Do not open the battery. There is a risk of short-circuit-ing.
• The battery can be damaged by pointed objects such as nails or screwdrivers or by force applied externally. An internal short circuit may occur, causing the battery to burn, smoke, explode or overheat.
• Only use the battery in the manufacturer’s products. This is the only way in which you can protect the battery against dangerous overload.
• Protect the battery against heat, e.g. against continuous intense sunlight, fire, dirt, water and moisture. There is a risk of explosion and short-circuiting.
• Never make warning signs on the machine unrecognis-able.
• The power tool is delivered with a laser warning sign (see table: “Symbols and their meaning”).
• Do not direct the laser beam at persons or animals and do not stare into the direct or reflected laser beam yourself. You could blind somebody, cause accidents or damage your eyes.
• Do not make any modifications to the laser equip-ment. The setting options described in these operating instructions can be used safely.
• Do not use the laser goggles (accessory) as protective goggles. The laser goggles make the laser beam easier to see; they do not protect you against laser radiation.
• Do not use the laser goggles (accessory) as sunglasses or while driving. The laser goggles do not provide full UV protection and impair your ability to see colours.
• Warning! If operating or adjustment devices other than those specified here are used or other proced-ures are carried out, this can lead to dangerous expos-ure to radiation.
• Do not replace the integrated laser with a laser of an-other type. A laser that is not compatible with this power tool could pose a risk to persons.
• Caution! When using the power tool with Bluetooth®, a fault may occur in other devices and systems, aero-planes and medical devices (e.g. pacemakers, hearing aids).

Noise Information
Noise emission values determined according to EN IEC 62841-3-9. Typically, the A-weighted noise level of the power tool is: Sound pressure level 93 dB(A); sound power level 106 dB(A). Uncertainty K = 3 dB.

Wear hearing protection!
The noise emission value given in these instructions has been measured in accordance with a standardised measur-ing procedure and may be used to compare power tools. It may also be used for a preliminary estimation of noise emis- sions.
The noise emission value given represents the main applica-tions of the power tool. However, if the power tool is used for other applications, with different application tools or is poorly maintained, the noise emission value may differ. This may significantly increase noise emissions over the total working period.

To estimate noise emissions accurately, the times when the tool is switched off, or when it is running but not actually be-ing used, should also be taken into account. This may signi-ficantly reduce noise emissions over the total working period.

Assembly

• Remove the battery from the power tool before carry-ing out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be re-moved for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.

• Assemble the saw stand properly before mounting the power tool. Correct assembly is important to prevent the risk of collapsing.
• Mount the power tool on the saw stand in the transport position.

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 remove the battery.
  • Wait until the saw blade has come to a complete stop.
  • Determine the cause of the blockage and eliminate it.

External Dust Extraction
You can also attach a dust extraction hose (35 mm diameter) to the extraction adapter (26) for extraction.

• Connect the dust extraction hose to the extraction adapter (26).

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.

Cleaning the dust extraction adapter
To ensure optimum extraction, the dust extraction adapter (26) must be cleaned regularly.

• Pull the dust extraction adapter (26) off the chip ejector (24) with a twisting motion.
• Remove workpiece fragments and chippings.
• Reattach the dust extraction adapter to the chip ejector with a twisting motion until it engages above the chip ejector holding ring.

Changing the Saw Blade

• Remove the battery from the power tool before carrying out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be removed for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.
• Wear protective gloves when fitting the saw blade. There is a risk of injury when touching the saw blade.

Only use saw blades that have a maximum permitted speed higher than the no- load speed of the power tool.  Only use saw blades that match the specifications given in this operating manual and that have been tested and marked in accordance with EN 847-1. Only use saw blades that are recommended by the power tool manufacturer and are suitable for use on the material you want to saw. This will prevent the saw teeth overheating when sawing.

Start-up

Inserting the Battery

• Use only original Bosch lithium-ion batteries with the voltage stated on the type plate of your power tool. Using other batteries can lead to injuries and pose a fire hazard.
  • Push the charged battery (32) into the battery bay of the power tool until the battery is securely locked.

Switching on (see figure L)

• To switch on the power tool, first slide the lock-off button (2) to the middle and then press and hold the on/ off switch (65).
• Note: For safety reasons, the on/off switch (65) cannot be locked; it must remain pressed during the entire operation.

Switching off
To switch off, release the on/off switch (65).

ECO mode
If the power tool is operated in the energy-saving ECO mode, the battery life may be up to 20% longer. If the ECO mode is active, the symbol E is shown on the speed setting/mode indicator (49). In addition, the ECO mode indicator (47) lights up.

User interface
The user interface (3) is used to preselect the speed and to indicate the status of the power tool.

Speed preselection
An ECO mode and three speed settings are preset. You can use the button for speed preselection (48) to preselect the required speed, even during operation.

Connectivity functions
In conjunction with the Bluetooth® Low Energy Module GCY 42, the following connectivity functions are available for the power tool:

• Registration and personalisation
• Status check, output of warning messages
• General information and settings
• Management
• Setting the speed levels

Read the corresponding operating instructions for information about the Bluetooth® Low Energy Module GCY 42. Further information can be found under the Power tool status display on a mobile device if it is connected via Bluetooth® wireless technology.

Practical advice

General sawing instructions

• Always tighten the locking knob (12) and the clamping handle (14) firmly before sawing. Otherwise the saw blade can become wedged in the workpiece.
• Always tighten the locking knob (12) 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.
• With the Bluetooth® Low Energy Module GCY 42, the power tool is equipped with a radio interface. Local operating restrictions, e.g. in aircraft or hospitals, must be observed.
• In areas in which the Bluetooth® wireless technology must not be used, the Bluetooth® Low Energy Module GCY 42 and the coin cell must be removed.

The free end of long and heavy workpieces must have something placed underneath it or be supported. Do not saw warped/bent workpieces. The workpiece must always have a straight edge to face against the fence. Only saw materials which are permitted within the scope of the intended use.

Protect the saw blade against impact and shock. Do not subject the saw blade to lateral pressure. 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.

Marking the Cutting Line (see figure M)
Two laser beams indicate 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.

• To do this, switch on the laser beams by briefly pressing the on/off switch (65) without pressing the lock-off button (2).
• Position your mark on the workpiece between the two laser lines.

Note:
Before sawing, check if the cutting line is still indicated correctly (see “Adjusting the laser”, page 29). Vibrations during intensive use, for example, can cause the laser beams to become misaligned.

Position of the operator (see figure N)

• 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.

Replacing insert plates (see figure O)
The insert plates (10) can become worn after prolonged use of the power tool. Replace faulty insert plates.

• Bring the power tool into the work position.
• Loosen the screws (66) using the hex key (18) 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 (66) 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 new left-hand insert plate.

Permissible workpiece dimensions

• With horizontal spacer (height x width: 60 mm x 400 mm)
• With vertical spacer (height x width: 72 mm x 50 mm)

Minimum workpiece dimensions (= all workpieces that can be secured left or right of the saw blade using the supplied screw clamp (19)): 160 mm x 35 mm (length x width)

• Maximum cutting depth (0°/0°): 120 mm

Sawing

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

• Slide the glide arm (34) all the way back and secure it in this position. Make sure that the depth stop (28) is pressed all the way in and that the adjusting screw (27) fits through the recess without touching the depth stop when moving the glide arm.
• Firmly clamp the workpiece as appropriate for its dimensions.
• Set the required mitre and/or bevel angle as necessary.
• Switch on the power tool.
• Slowly guide the glide arm (34) downwards using the handle (1).
• 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 glide arm (34) upwards.

Sawing with Slide Movement (see figure Q)

• 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 glide 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 glide arm (34). Check if the complete glide mechanism is operative by sliding the glide arm (34) back and forth.
• Firmly clamp the workpiece as appropriate for its dimensions.
• Set the required mitre and/or bevel angle as necessary.
• Pull the glide arm (34) away from the fence (7) by the handle (1) until the saw blade is in front of the workpiece.
• Switch on the power tool.
• Slowly guide the glide arm (34) downwards using the handle (1).
• Now push the glide arm (34) towards the fence (7) 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 glide arm (34) upwards.

Sawing workpieces of the same length (see figure R)
The length stop (40) (accessory) can be used for easily sawing workpieces of the same length. The length stop can be mounted on either side of the saw table extension (8).

• Loosen the locking screw (39) and move the length stop (40) over the clamping screw (67).
• Re-tighten the locking screw (39).
• Set the saw table extension (8) to the required 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 or use a spacer.

• Swivel the depth stop (28) outwards.
• Use the handle (1) to swivel the glide arm (34) into the required position.
• Turn the adjusting screw (27) until the end of the screw touches the depth stop (28).
• Slowly guide the glide arm (34) 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.

Working on mouldings
Mouldings can be sawn in two different ways:

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.
