Safety Notes
General Power Tool Safety Warnings
WARNING When using electric tools basic safety precautions should always be followed
to reduce the risk of fire, electric shock and personal injury including the following. Read all these instructions before attempting to operate this product and save these instructions. The term “power tool” in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless) power tool.
Work area safety f Keep work area clean and well lit. Cluttered or dark areas
invite accidents. f 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. f Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical safety f 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. f 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.

32 | English
f Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
f Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges and moving parts. Damaged or entangled cords increase the risk of electric shock.
f 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.
f 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
f Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
f Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
f 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.
f 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.
f Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
f Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
f If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
Power tool use and care
f 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.
f 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.
f Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

f 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.
f Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
f Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
f Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
Service f Have your power tool serviced by a qualified repair per-
son using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
Safety Warnings for Sliding Mitre Saws
f The power tool is provided with a warning label in English (marked with number 3 in the representation of the power tool on the graphics page).
LASER RADIATION DO NOT STARE INTO THE BEAM
CLASS 2 LASER PRODUCT EN 60825-1: 2007 <1mW, 635 nm
f Never make warning signs on the machine unrecognisable.
f Never stand on the power tool. Serious injuries can occur when the power tool tips over or when inadvertently coming into contact with the saw blade.
f Make sure that the guard operates properly and that it can move freely. Never lock the guard in place when opened.
f Never remove cutting remainders, wood chips, etc. from the sawing area while the machine is running. Always guide the tool arm back to the neutral position first and then switch the machine off.
f Guide the saw blade against the workpiece only when the machine is switched on. Otherwise there is damage of kickback, when the saw blade becomes wedged in the workpiece.
f Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery causing loss of control.
f Operate the power tool only when the work area to the workpiece is clear of any adjusting tools, wood chips, etc. Small pieces of wood or other objects that come in contact with the rotating saw blade can strike the operator with high speed.

f Keep the floor free of wood chips and material remainders. You could slip or trip.
f Always firmly clamp the piece to be worked. Do not saw workpieces that are too small to clamp. Otherwise, the clearance of your hand to the rotating saw blade is too small.
f Use the machine only for cutting the materials listed under Intended Use. Otherwise, the machine can be subject to overload.
f If the saw blade should become jammed, switch the machine off and hold the workpiece until the saw blade comes to a complete stop. To prevent kickback, the workpiece may not be moved until after the machine has come to a complete stop. Correct the cause for the jamming of the saw blade before restarting the machine.
f Keep your fingers clear of the movable parts of the glide arm. Danger of fingers being crushed or contused and considerably injured.
f Before switching on and during the complete sawing, hold the handle firmly. While sawing, carry out a controlled motion with the glide arm. A moment of inattention while operating the extremely smooth-running glide arm can result in serious personal injury.
f Always saw through the workpiece from front to rear. Otherwise, there is danger of kickback when the saw blade becomes wedged in the workpiece.
f 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.
f Always use saw blades with correct size and shape (diamond versus round) of arbor holes. Saw blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.
f Do not use high speed steel (HSS) saw blades. Such saw blades can easily break.
f Do not touch the saw blade after working before it has cooled. The saw blade becomes very hot while working.
f Never operate the machine without the insert plate. Replace a defective insert plate. Without flawless insert plates, injuries are possible from the saw blade.
f Check the cable regularly and have a damaged cable repaired only through an authorised customer service agent for Bosch power tools. Replace damaged extension cables. This will ensure that the safety of the power tool is maintained.
f Store the machine in a safe manner when not being used. The storage location must be dry and lockable. This prevents the machine from storage damage, and from being operated by untrained persons.
f Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself, not even from a distance. This power tool produces laser class 2 laser radiation according to EN 60825-1. This can lead to persons being blinded.

English | 33
f Do not replace the installed laser with another laser type. A laser that does not fit to this power tool could pose dangers for other persons.
f Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
f Never leave the machine before it has come to a complete stop. Cutting tools that are still running can cause injuries.
f Never use the machine with a damaged cable. Do not touch the damaged cable and pull the mains plug when the cable is damaged while working. Damaged cables increase the risk of an electric shock.
Products sold in GB only: Your product is fitted with a BS 1363/A approved electric plug with internal fuse (ASTA approved to BS 1362). If the plug is not suitable for your socket outlets, it should be cut off and an appropriate plug fitted in its place by an authorised customer service agent. The replacement plug should have the same fuse rating as the original plug. The severed plug must be disposed of to avoid a possible shock hazard and should never be inserted into a mains socket elsewhere. Products sold in AUS and NZ only: Use a residual current device (RCD) with a rated residual current of 30 mA or less.

mm 1.72.6

Measured sound values determined according to EN 61029.
Typically the A-weighted noise levels of the product are: Sound pressure level 93 dB(A); Sound power level 106 dB(A). Uncertainty K =3 dB. Wear hearing protection!
Vibration total values (triax vector sum) determined according to EN 61029: Vibration emission value ah <2.5 m/s2, Uncertainty K =1.5 m/s2.
The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 61029 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure. The declared vibration emission level represents the main applications of the tool. However if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period. An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

f Always tighten the locking knob 15 firmly before sawing. Otherwise the saw blade can become wedged in the workpiece.
Stationary or Flexible Mounting
f To ensure safe handling, the machine must be mounted on a level and stable surface (e. g., workbench) prior to using.
Mounting to a Working Surface (see figure b1)
Fasten the power tool with suitable screw fasteners to the working surface. The mounting holes 12 serve for this purpose.
Mounting to a Bosch Saw Stand (GTA 2500 W, GTA 3700, GTA 3800) (see figure b2)
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 underlaying long workpieces. f Read all safety warnings and instructions included with
the worktable. Failure of observing safety warnings and instructions can lead to electrical shock, fire and/or cause serious injuries. f Assemble the worktable properly before mounting the power tool. Perfect assembly is important in order to prevent the risk of collapsing.
Mount the power tool in transport position on the saw stand.
Dust/Chip Extraction
Dusts from materials such as lead-containing coatings, some wood types, minerals and metal can be harmful to one’s health. Touching or breathing-in the dusts can cause allergic reactions and/or lead to respiratory infections of the user or bystanders. Certain dusts, such as oak or beech dust, are considered as carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.
Always use dust extraction. Provide for good ventilation of the working place. It is recommended to wear a P2 filter-class respirator.

English | 37
Observe the relevant regulations in your country for the materials to be worked.
The dust/chip extraction can be blocked by dust, chips or workpiece fragments.
Switch the machine off and pull the mains plug from the socket outlet.
Wait until the saw blade has come to a complete stop. Determine the cause of the blockage and correct it. f Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Integrated Dust Extraction (see figure c) For basic dust collection, use the dust bag 1 provided. f Check and clean the dust bag each time after using. f When sawing aluminium, remove the dust bag to avoid
the risk of fire. Insert and turn dust bag 1 onto the extraction adapter 2 in
such a manner that the pin of the extraction adapter engages in the recess of the dust bag.
During sawing, the dust bag and the extraction adapter may never come in contact with moving tool components.
Always empty the dust bag in good time.
External Dust Extraction
For dust extraction, you can also connect the extraction adapter 2 to a vacuum hose (Ø 35 mm). Insert the vacuum hose into the extraction adapter 2.
The vacuum cleaner must be suitable for the material being worked.
When vacuuming dry dust that is especially detrimental to health or carcinogenic, use a special vacuum cleaner.
Cleaning the Extraction Adapter To ensure optimum extraction, the extraction adapter 2 must be cleaned regularly. Pull off extraction adapter 2 from sawdust ejector 41 with
a twisting motion. Remove workpiece fragments and chippings. Mount the extraction adapter onto the sawdust ejector
again with a twisting motion until it engages over the holding ring of the sawdust ejector.
Changing the Saw Blade (see figures d1d4)
f Before any work on the machine itself, pull the mains plug.
f When mounting the saw blade, wear protective gloves. Danger of injury when touching the saw blade.
Use only saw blades whose maximum permitted speed is higher than the no-load speed of the power tool.
Use only saw blades that correspond with the characteristic data given in these operation instructions and that are tested and marked in accordance with EN 847-1.
Use only saw blades recommended by the tool manufacturer, and suitable for sawing the materials to be cut.
Removing the Saw Blade
Bring the power tool into the working position.

Starting Operation
f Observe the mains voltage! The voltage of the power source must correspond with the data on the type plate of the machine.
Switching On (see figure L) For starting operation, pull the On/Off switch 60 in the di-
rection of the handle 4. Note: For safety reasons, the On/Off switch 60 cannot be locked; it must remain pressed during the entire operation.
The glide arm can only be guided downward by pressing locking lever 5. For sawing, the locking lever 5 must be pushed in addition
to pressing the On/Off switch.
Switching Off To switch off the machine, release the On/Off switch 60.
Reduced starting current The electronic reduced starting current limits the power consumption when switching the tool on and enables operation from a 13 ampere fuse. Note: When the machine runs at full speed immediately after switching on, the reduced starting current has failed. The power tool should be sent immediately to an after-sales service (for addresses, see section “After-sales Service and Customer Assistance”, page 45).
Working Advice
General Sawing Instructions f Always firmly tighten locking knob 15 and lock lever 17
before sawing. Otherwise the saw blade could become jammed in the workpiece.
Permissible Workpiece Dimensions Maximal workpiece sizes:

f 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 possibly mounted auxiliary stops or adjust them accordingly.
Protect the saw blade against impact and shock. Do not subject the saw blade to lateral pressure.
Do not saw warped/bent workpieces. The workpiece must always have a straight edge to face against the fence.
Long workpieces must be underlaid or supported at their free end.
Marking the Cutting Line (see figure M)
Two laser beams indicate the cutting width of the saw blade. This allows for exact positioning of the workpiece for sawing, without having to open the retracting blade guard. Switch on the laser beams with switch 61. Align your mark on the workpiece between both laser lines. Note: Before sawing, check if the cutting width is still indicated correctly (see “Adjusting the Laser”, page 43). The laser beams, as an example, can misadjust through vibrations from intensive use.
Position of the Operator (see figure N) f Do not stand in a line with the saw blade in front of the
machine. Always stand aside of the saw blade. This protects your body against possible kickback.
Keep hands, fingers and arms away from the rotating saw blade.
Do not stand in front of the glide arm with your arms crossed.
Replacing Insert Plates (see figure O) The red insert plates 13 can become worn after long use of the machine.
Replace defective insert plates.
Bring the power tool into the working position. Unscrew screws 62 with the provided Allen key (4 mm) 20
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 62 so that the saw blade does not come into contact with the insert plate over the complete length of the possible slide motion. Repeat the work steps in the same manner for the left-hand insert plate.

Sawing
Sawing without Slide Movement (Cutting Off) (see figure P) Slide glide arm 28 completely to the rear and secure it in
this position (see “Securing the Glide Arm”, page 38). Make sure that the depth stop 30 is pushed completely inward and that adjusting screw 29 fits through the recess without touching the depth stop when moving the glide arm. Firmly clamp the workpiece as appropriate for its dimensions. Adjust the desired mitre and/or bevel angle. Switch on the machine. Press locking lever 5 and slowly guide the glide arm downward with handle 4. Saw through the workpiece applying uniform feed. Switch off the machine and wait until the saw blade has come to a complete stop. Slowly guide the glide arm upward.
Sawing with Slide Movement (see figure Q) f Before switching on and during the complete sawing,
hold the handle firmly. While sawing, carry out a controlled motion with the glide arm. A moment of inattention while operating the extremely smooth-running glide arm can result in serious personal injury.
Release glide arm 28 (see “Releasing the Glide Arm”, page 38). Check if the complete glide mechanism is operative by sliding the glide arm 28 back and forth.
Firmly clamp the workpiece as appropriate for its dimensions.
Adjust the desired mitre and/or bevel angle. Pull the glide arm away from the fence 10 until the saw
blade is in front of the workpiece. Switch on the machine. Press locking lever 5 and slowly guide the glide arm down-
ward with handle 4. Now, push the glide arm toward the fence 10 and saw
through the workpiece with uniform feed. Switch off the machine and wait until the saw blade has
come to a complete stop. Slowly guide the glide arm upward.

English | 41
Sawing Workpieces of the Same Length (see figure R) The material stop 36 can be used for easily sawing workpieces to the same length.
The material stop can be mounted on either side of the saw table extension 11. Loosen lock screw 35 and swing the material stop 36 over
clamping screw 63. Retighten lock screw 35. Adjust the saw table extension 11 to the desired length
(see “Extending the Saw Table”, page 38).
Adjusting the Depth Stop (Sawing Grooves) (see figure S)
The depth stop must be adjusted when sawing a groove or using a spacer (e.g.: Bosch MSF 110). Swivel the depth stop 30 outward. Press locking lever 5 and tilt the glide arm to the desired
position. Turn adjusting screw 29, until the screw end touches
depth stop 30. Slowly guide the glide arm upward.
Special Workpieces
When sawing curved or round workpieces, these must be especially secured against slipping. At the cutting line, no gap may exist between workpiece, fence and saw table.
Provide for special fixtures, if required.
Sawing Profile Strips/Mouldings (Floor and Ceiling Strips)
Profile strips/mouldings can be sawn in two different ways:
Placed against the fence Lying flat on the saw table.
In addition, the cut can be perfomed with or without slide movement depending on the width of the profile strip/moulding.
Always make trial cuts with the mitre angle setting first on scrap wood.

Checking and Adjusting the Basic Adjustment
To ensure precise cuts, the basic adjustment of the machine must be checked and adjusted as necessary after intensive use. A certain level of experience and appropriate specialty tools are required for this.
A Bosch after-sales service station will handle this maintenance task quickly and reliably.
Adjusting the Laser Note: To test the laser function, the machine must be connected to power.
f While adjusting the laser (e.g. when moving the glide arm), never actuate the On/Off switch. Accidental starting of the power tool can lead to injuries.
Bring the power tool into the working position. Turn the saw table 38 to the 0° detent 18. The lever 16
must be felt to engage in the detent. Switch on the laser beams with switch 61.
Checking: (see figure T1)
Draw a straight cutting line on the workpiece. Press locking lever 5 and slowly guide the glide arm down-
ward with handle 4. Align the workpiece in such a manner that the teeth of the
saw blade are in alignment with the cutting line. Hold the workpiece in this position and slowly guide the
glide arm upward. Clamp the workpiece. Switch on the laser beams with switch 61.
Throughout the complete length, the laser beams must have the same clearance to the drawn cutting line on the workpiece, even when lowering the glide arm.
Adjusting the Flush Levelling: (see figure T2) Using the Allen key (2 mm) 21, turn the respective adjust-
ment screw 64 until the laser beam has the same clearance to the drawn cutting line on the workpiece over the complete length.
One rotation in anticlockwise direction moves the laser beam from left to right; one rotation in clockwise direction moves the laser beam from right to left.
Adjusting the Parallelism: (see figure T3) Loosen the two screws 65 of laser protection cap 27 with
the Allen key (4 mm) 20. Note: To access the front screw of the laser protection cap, the glide arm must be tilted down a little until the Allen key can be inserted through one of the slots of the retracting blade guard. Loosen fastening screw 66 (approx. 12 turns) with the Allen key (2 mm) 21. Do not completely unscrew the screw. Move the mounting plate of the laser right or left until the laser beams are parallel to the drawn cutting line on the workpiece over the complete length. Hold the mounting plate in this position and tighten fastening screw 66 again. After adjusting, check the flush alignment with the cutting line once more. If required, align the laser beams with the set screws 64 one more time.

Retighten the lock lever 17 again. When the angle indicators 33 and 24 are not in line with the 45° marks of scale 32 after adjusting, firstly once more check the 0° setting for the bevel angle and the angle indicators. Then repeat the adjustment of the 45° bevel angle.
Aligning the Scale for Mitre Angles
Bring the power tool into the working position. Turn the saw table 38 to the 0° detent 18. The lever 16
must be felt to engage in the detent. Checking: (see figure X1) Adjust an angle gauge to 90° and position it between the
fence 10 and the saw blade 40 on the saw table 38. The leg of the angle gauge must be flush with the saw blade 40 over the complete length. Adjusting: (see figure X2) Loosen all four set screws 73 with the Allen key (4 mm) 20
and turn the saw table 38 together with the scale 37 until the leg of the angle gauge is flush with the saw blade over the complete length. Retighten the screws again.

When the angle indicator 59 is not in line with the 0° mark of scale 37 after adjusting, loosen screw 74 with a Phillips screwdriver and align the angle indicator alongside the 0 ° mark.
Adjusting the Clamping Force of Lock Lever 17 (see figure Y) The clamping force of lock lever 17 can be readjusted.
Checking:
The clamping force of the lock lever must securely hold the position of the glide arm at any bevel angle.
Adjusting: Loosen the lock lever 17. Turn set screw 75 in anticlockwise direction with a socket
spanner (size 17 mm) to reduce the clamping force, or increase the clamping force by turning in clockwise direction. Adjust a vertical bevel angle, retighten lock lever 17 and check if the desired clamping force has been reached.
Transport (see figure Z)
Before transporting the power tool, the following steps must be carried out: Slide glide arm 28 completely to the rear and secure it in
this position (see “Securing the Glide Arm”, page 38). Make sure that the depth stop 30 is pushed completely in-
ward and that adjusting screw 29 fits through the recess without touching the depth stop when moving the glide arm. Guide the glide arm downward until transport safety-lock 31 can be pushed completely inward. Slide the table extensions 11 completely inward. Set the vertical bevel angle to 0° and tighten the lock lever 17. Turn saw table 38 leftward to the stop and tighten locking knob 15. Wind up the mains cable and tie it together with Velcro strap 76. Remove all accessories that cannot be mounted firmly to the power tool. If possible, place unused saw blades in an enclosed container for transport. Carry the machine by the transport handle 7 or hold it by the recessed handles 19 on the sides of the saw table.
