English Safety instructions General Power Tool Safety Warnings WARNING Read all safety warnings, instruc- tions, illustrations and specifica- tions 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 (cord- less) power tool. Work area safety u Keep work area clean and well lit. Cluttered or dark areas invite accidents. u 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. u Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control. Electrical safety u 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. u Avoid body contact with earthed or grounded sur- faces, such as pipes, radiators, ranges and refrigerat- ors. There is an increased risk of electric shock if your body is earthed or grounded. u Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of elec- tric shock. u Do not abuse the cord. Never use the cord for carry- ing, 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. 1 609 92A 8HX | (23.03.2023) Bosch Power ToolsEnglish | 27 u When operating a power tool outdoors, use an exten- sion cord suitable for outdoor use. Use of a cord suit- able for outdoor use reduces the risk of electric shock. u If operating a power tool in a damp location is un- avoidable, use a residual current device (RCD) protec- ted supply. Use of an RCD reduces the risk of electric shock. Personal safety u 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 per- sonal injury. u 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. u 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. u 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. u Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. u 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. u 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. u 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 u 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. u 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. u 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. u 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. u 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. u 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. u 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. u 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 u 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 u 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. u 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. u 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. u 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 Bosch Power Tools 1 609 92A 8HX | (23.03.2023)28 | English of the workpiece and violently throw the blade assembly towards the operator. u 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. u 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. u 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. u 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. u 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. u 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. u 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. u 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. u 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. u 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. u 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. u Let the blade reach full speed before contacting the workpiece. This will reduce the risk of the workpiece be- ing thrown. u 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. u 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. u 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. u 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. u Keep your work area clean. Material mixtures are partic- ularly hazardous. Light metal dust may catch fire or ex- plode. u 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. u Do not use saw blades made from high speed steel (HSS). Such saw blades can easily break. u 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. u 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. u Do not touch the saw blade after working before it has cooled. The saw blade becomes very hot while working. Products sold in GB only: Your product is fitted with an 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 au- thorised 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. u The power tool is delivered with a laser warning sign (see table: "Symbols and their meaning"). 1 609 92A 8HX | (23.03.2023) Bosch Power ToolsEnglish | 29 u If the text of the laser warning label is not in your na- tional language, stick the provided warning label in your national language over it before operating for the first time. u Never make warning signs on the machine unrecognis- able. 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. u If laser radiation hits your eye, you must close your eyes and immediately turn your head away from the beam. u Do not make any modifications to the laser equip- ment. The setting options described in these operating instructions can be used safely. u Do not let children use the power tool unsupervised.

Permitted workpiece dimensions (maximum/minimum):(see "Permissible workpiece dimensions", page35) Noise Information Noise emission values determined according to ENIEC62841-3-9. Typically, the A-weighted noise level of the power tool is: Sound pressure level 88dB(A); sound power level 101dB(A). Uncertainty K = 3dB. 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 u Avoid starting the power tool unintentionally. The mains plug must not be connected to the power supply during assembly or when carrying out any kind of work on the power tool.

The flexible connector system en- ables a multitude of extension or expansion variants (see figureG). – Insert the workpiece support(26) into the openings(47) on the power tool or into the openings(48) of the second workpiece support as required. u Never carry the power tool using the workpiece sup- ports. Only use the transport devices to transport the power tool. Fitting the Clamping Wheel (see figureA2) The clamping wheel(45) fixes the selected bevel angle and is required for safe operation. – Unscrew the hex nut from the threaded bolts(49). – Screw the clamping wheel(45) clockwise onto the threaded bolts(49) and tighten it. Fitting the Adjustable Fence (see figureA3) The adjustable fence(28) must be fitted before sawing. – Slide the fence(28) on the right of the saw blade into the corresponding groove and tighten the locking screw(44). The levelled side of the fence must face inwards towards the saw blade. Stationary or flexible mounting u To ensure safe handling, the power tool must be mounted on a flat, stable work surface (e.g. work bench) before use. Mounting on a work surface (see figure B1−B2) – Use suitable screw fasteners to secure the power tool to the work surface. The holes (15) are used for this pur- pose.

Bosch Power Tools 1 609 92A 8HX | (23.03.2023)32 | English – Firmly clamp the base of the power tool to the work sur- face with commercially available screw clamps. Mounting on a Bosch saw stand With the height-adjustable legs, Bosch GTA saw stands provide firm support for the power tool on any surface. The workpiece supports of the saw stand are used for underlay- ing long workpieces. u Read all the warnings and instructions included with the saw stand. Failure to observe the warnings and fol- low instructions may result in electric shock, fire and/or serious injury. u 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. Flexible installation (not recommended) (see figure B3) If, in exceptional circumstances, it is not possible to mount the power tool on a flat and stable work surface, you can im- provise by setting it up with the tilt protector. u Without the tilt protector, the power tool will not be stable and can tip over especially when sawing max- imum mitre and/or bevel angles. – Rotate the tilt protector (20) inwards or outwards until the power tool is positioned straight on the work surface. 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 reac- tions 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 contain- ing asbestos may only be machined by specialists. – Use a dust extraction system that is suitable for the ma- terial 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. u 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 (seefigureC) For basic chip collection, use the dust bag(37) provided. – Turn the transport handle(3) so that it is vertical. – Place the dust bag(37) onto the extraction adapter(50) and turn so that the pin of the dust bag locks in place in the recess of the extraction adapter. During sawing, the dust bag must not come into contact with moving tool components. Always empty the dust bag in good time. u Check and clean the dust bag each time after using. u When sawing aluminium, remove the dust bag to avoid the risk of fire. External Dust Extraction You can also attach a dust extraction hose (35mm dia- meter) to the extraction adapter(50) for extraction. – Connect the dust extraction hose to the extraction adapter(50). 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. Changing the saw blade (see figures D1−D4) u Pull the plug out of the socket before carrying out any work on the power tool. u 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 EN847-1. 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. Removing the Saw Blade – Bring the power tool into the work position. – Swivel the retracting blade guard(12) to the back and hold it in this position. – Turn the hex socket screw(51) with the hex key (6mm)(43) and at the same time push the spindle lock(33) until it engages. – Keep holding the spindle lock(33) and loosen the hex socket screw(51) by turning it clockwise (left-hand thread). – Remove the clamping flange(52). – Remove the saw blade(32). – Slowly push the retracting blade guard back down. Fitting the saw blade u When fitting the saw blade, make sure that the cutting direction of the teeth (arrow direction on the saw blade) matches the direction of the arrow on the pro- tective guard. If required, clean all the parts you want to fit before installing them. 1 609 92A 8HX | (23.03.2023) Bosch Power ToolsEnglish | 33 – Swivel the retracting blade guard(12) to the back and hold it in this position. – Place the new saw blade on the inner clamping flange(53). – Fit the clamping flange(52) and the hex socket screw(51).

For quick and precise setting of frequently used bevel angles, fixed positions have been provided for the angles 0°, 22.5° and 45°. – Make sure that the clamping wheel(45) is fitted (see "Fit- ting the Clamping Wheel (see figureA2)", page31). Setting Standard Bevel Angles (see figureL) – Pull the adjustable fences(28) all the way out or remove them completely. – Release the clamping wheel(45). – Pull the locking lever(46) out and engage it in the free running position. This enables you to use the complete bevel angle range (left and right). – Swivel the tool arm left or right by the handle(9) until the angle indicator(30) shows the required standard bevel angle. – Turn the locking lever(46). The locking lever must be felt to engage in the position of the required standard bevel angle. – Retighten the clamping wheel(45). Setting any bevel angle – Pull the adjustable fences(28) all the way out or remove them completely. – Release the clamping wheel(45). – Pull the locking lever(46) out and engage it in the free running position. This enables you to use the complete bevel angle range (left and right). – Swivel the tool arm left or right by the handle(9) until the angle indicator(30) shows the required bevel angle. – Retighten the clamping wheel(45). Start-up u Products that are only sold in AUS and NZ: Use a resid- ual current device (RCD) with a nominal residual current of 30 mA or less. u 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. u Always tighten the locking knob(18) and the clamp- ing wheel(45)firmly before sawing. Otherwise the saw blade can become wedged in the workpiece. Switching On the worklight The worklight improves visibility in the immediate work area. You can achieve particularly good sawing results by using the worklight together with the cutting line that is marked by the laser beams. – Switch on the worklight with the switch(6). u Do not look directly into the worklight; it can blind you. Switching on (see figureM) – To switch on the power tool, first slide the lock-off button(7) to the middle and then press and hold the on/ off switch(8). Note: For safety reasons, the on/off switch (8) cannot be locked; it must remain pressed during the entire operation. Switching off – To switch off, release the on/off switch (8). Soft Start The Soft Start restricts the power consumption when the power tool is switched on and enables operation with a 16A fuse. Note: If the power tool runs at full speed immediately after being switched on, this means that the Soft Start has failed. The power tool must be sent to the after-sales service without delay. Sawing General sawing instructions u Always tighten the locking knob(18) and the clamp- ing wheel(45)firmly before sawing. Otherwise the saw blade can become wedged in the workpiece. u 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 sub- ject 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. 1 609 92A 8HX | (23.03.2023) Bosch Power ToolsEnglish | 35 The free end of long and heavy workpieces must have some- thing 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 po- sition of the tool arm. Position of the operator (see figure N) u 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 work- pieces), 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 (27) and (28). – Firmly clamp the workpiece as appropriate for its dimen- sions. – Pull the tool arm away from the fence (27) until the saw blade is in front of the workpiece. – Switch the power tool on. – Slowly guide the tool arm downwards using the handle (9). – Now push the tool arm towards the fences (27) and (28) 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
