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 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 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 cord away from heat, oil, sharp edges, and 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 inattention while operating power tools may result in serious personal injury.
  • 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.
  • 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 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, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
  • If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

Power tool use and care

  • Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
  • Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
  • Disconnect the plug from the power source and/or 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.
  • 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. 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.

Service

  • Have your power tool serviced by a qualified repair per-son using only identical replacement parts. This will en-sure that the safety of the power tool is maintained.

Safety Warnings for Combination Saws

  • The power tool is provided with a laser warning label (marked with number 40 in the representation of the power tool on the graphics page).

  • If the text of the warning label is not in your national language, stick the provided warning label in your national language over it before operating for the first time.
  • Do not direct the laser beam at persons or animals and do not stare into the direct or reflected laser beam yourself, not even from a distance. You could blind somebody, cause accidents or damage your eyes.
  • If laser radiation strikes your eye, you must deliberately close your eyes and immediately turn your head away from the beam.
  • Do not use any optical instruments such as binoculars to view the radiation source. Doing so can damage your eye.
  • Do not direct the laser beam at persons who are looking through binoculars or similar instruments. Doing so can damage their eye.
  • Do not make any modifications to the laser equipment. The setting options described in these operating instructions can be used safely.
  • Do not replace the installed laser or LED with another type. Lasers or LEDs which are not suitable for this power tool could pose dangers to persons.
  • Repair or replacement must be performed by an authorized after-sales service centre in order to prevent safety risks.
  • Never make warning signs on the machine unrecognizable.
  • 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.
  • Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery causing loss of control.
  • 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.
  • Keep the floor free of wood chips and material remainders. You could slip or trip.
  • Use the machine only for cutting the materials listed under Intended Use. Otherwise, the machine can be subject to overload.
  • If the saw blade should become jammed, switch the ma-chine 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.
  • 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 kick-back.
  • Always use blades with correct size and shape (diamond versus round) of arbor holes. Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.
  • Do not use high speed steel (HSS) saw blades. Such saw blades can easily break.
  • Do not touch the saw blade after working before it has cooled. The saw blade becomes very hot while working.
  • 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.
  • Do not replace the installed laser or LED with another type. Lasers or LEDs which are not suitable for this power tool could pose dangers to persons.
  • Repair or replacement must be performed by an authorized after-sales service centre in order to prevent safety risks.
  • Check the cable regularly and have a damaged cable re-paired only through an authorized customer service agent for Bosch power tools. Replace damaged extension cables. This will ensure that the safety of the power tool is maintained.
  • 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.
  • Never leave the machine before it has come to a complete stop. Cutting tools that are still running can cause injuries.
  • 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.

Safety Warnings for Use as a Chop and Mitre Saw

  • Make sure that the guard operates properly and that it can move freely. Never lock the guard in place when opened.
  • 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.
  • Guide the saw blade against the workpiece only when the machine is switched on. Otherwise there is danger of kickback when the saw blade becomes wedged in the workpiece.
  • 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.
  • Never operate the machine without the insert plate. Replace a defective insert plate. Without flawless insert plates, injuries are possible from the saw blade.
  • Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.

Safety Warnings for Use as a Table Saw

  • Make sure that the guard operates properly and that it can move freely. It must face against the table before sawing and against the workpiece while sawing; never lock the guard in place when opened.
  • Never reach behind the saw blade in order to hold the workpiece, remove saw dust/wood chips or for any other reason. The clearance of your hand to the rotating saw blade is too small.
  • Guide the workpiece against the saw blade only when the machine is switched on. Otherwise there is damage of kickback, when the saw blade becomes wedged in the workpiece.
  • Only saw one workpiece at a time. Workpieces placed on top or aside of each other can cause the saw blade to jam or the workpieces to move against each other while saw-ing.
  • Always use the parallel guide or the angle guide. This improves the cutting accuracy and reduces the possibility of saw blade binding.
  • 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 authorized 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.

Technical Data

Permissible workpiece dimensions (maximal/minimal):
The values given are valid for a nominal voltage [U] of 230 V. For different voltages and models for specific countries, these values can vary.

Noise Information

  • Sound emission values are determined according to EN 61029-2-11.
  • Typically the A-weighted noise levels of the product are: Sound pressure level 91 dB(A); Sound power level 104 dB(A). Uncertainty K =3 dB.

Wear hearing protection

The noise emission value given in these instructions has been measured in accordance with a standardized measuring procedure and may be used to compare power tools. It may also be used for a preliminary estimation of noise emissions. The noise emission value given represents the main applications of the power tool. However, if the power tool is used for other applications, with different accessories 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 being used, should also be taken into account. This may significantly reduce noise emissions over the total working period.

Assembly and Transport

  • Avoid unintentional starting of the machine. During assembly and for all work on the machine, the power plug must not be connected to the mains supply.

Delivery Scope

The tilt-protector bar 6 is used for this purpose.

  • Never remove the tilt-protector bar. Without the use of the tilt-protector bar, the machine does not stand safely and can tip over, especially when sawing at maximum miter/bevel angles.
Dust/Chip Extraction

Dust 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 dust can cause allergic reactions and/or lead to respiratory infections of the user or bystanders. Certain dust, such as oak or beech dust, is considered 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.

Observe the relevant regulations in your country for the materials to be worked on

  • Prevent dust accumulation at the workplace. Dust can easily ignite.

The dust/chip extraction can be blocked by dust, chips, or workpiece fragments

  • Switch the machine off and pull the main 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.

Integrated Dust Extraction (see figure c)

For basic dust collection, use the dust bag 8 provided.

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

During sawing, the dust bag must never come into contact with the movable machine parts.

  • Press the clip of the dust bag 8 together and slide the dust bag over the sawdust ejector 9.
  • The clip must engage into the groove of the sawdust ejector.
  • Always empty the dust bag in good time.

External Dust Extraction

For dust extraction, a vacuum hose (size Ø 36 mm) can also be connected to the chip ejector 9.

  • Connect the vacuum hose with the chip ejector 9.
  • 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.

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

Illuminating the Work Area
Provide sufficient lighting for the direct working area.

  • For this, switch on the lighting unit 34 with the switch 35.

Marking the Cutting Line

A laser beam indicates the cutting line of the saw blade. This allows for the exact positioning of the workpiece for sawing, without having to open the retracting blade guard.

  • For this, switch the laser beam on with switch 36.
  • Align the cutting mark on your workpiece with reference to the right-hand edge of the laser line.
  • Before sawing, check if the cutting line is still indicated correctly. The laser beam, as an example, can misadjust due to vibrations after intensive use.

Position of the Operator

  • 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 cross your arms when operating the tool arm.

Permissible Workpiece Dimensions
Maximum workpiece sizes:

Minimum workpiece sizes (= all workpieces that can be clamped left or right from the saw blade with a screw clamp): 200 x 40 mm (length x width)

Cutting depth, max. (0°/0°): 95 mm
Replacing the Insert Plate

The red insert plate 24 can become worn after long use of the power tool.
Replace defective insert plates.

  • Bring the power tool into the chop and mitre saw working position.
  • Unscrew screw s49 using a cross-head screwdriver and remove the old insert plate.
  • Insert the new insert plate and screw all screws 49 in again.
  • Set the vertical bevel angle to 0° and saw through the insert plate.
  • Afterward, set the vertical bevel angle to 45° and saw into the cut again.

This procedure achieves that the insert plate is as close as possible to the teeth of the saw blade without touching it.

Sawing

Cutting Off

  • Firmly clamp the workpiece as appropriate for its dimensions.
  • Adjust the requested miter and/or bevel angle.
  • Switch on the machine.
  • Push button 17 and slowly guide the tool arm downward with the handle 18.
  • Saw through the workpiece applying uniform feed.
  • Switch off the machine and wait until the saw blade has come to a complete stop.
  • Guide the tool arm slowly 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 the workpiece, fence and saw table. Provide for special fixtures, if required.

Sawing Profile Strips/Mouldings (Floor and Ceiling Strips)

Profile strips/moldings can be sawn in two different ways:

  • Placed against the fence
  • Lying flat on the saw table.
  • Always make trial cuts with the miter angle setting first on scrap wood.

Floor Strips/Mouldings
The following table contains instructions for sawing floor strips/mouldings.

Ceiling Strips/Mouldings (According to US Standard)
When the ceiling strips/moldings are to be sawn lying flat on the saw table, the standard miter angles of 31.6° (horizontal) and 33.9° (vertical) must be set.
The following table contains instructions for sawing ceiling strips/moldings.

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

  • Bring the power tool into the table saw working position.
  • Turn the saw table 22 to the 0° detent 27. The lever 26 must be felt to engage in the detent.

Checking:

  • Draw a straight cutting line on the workpiece.
  • Push-button 17 and slowly guide the tool arm downward with the handle 18.
  • 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 tool arm upward again.
  • Clamp the workpiece.
  • Switch the laser beam on with switch 36.

The laser beam must be in alignment with the cutting line on the workpiece over the complete length, also when the tool arm is lowered.

Adjusting the Parallelism:

  • Undo the rubber cap 50.
  • Screw the adjustment screw 51 in or out using a suitable screwdriver until the laser beam is parallel with the cutting line on the workpiece over the complete length.

Adjusting the Flush Levelling:
An adjustment screw 52, which is located below the opening marked with “R/L”, is used for adjustment of the flush leveling.

  • Screw the adjustment screw 52 in or out with the slotted screwdriver provided until the parallel laser beam is flush with the 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 Lateral Deviation while Moving the Tool Arm:

  • Open the side rubber cap 53.
  • If the laser beam moves towards the left when lowering the tool arm, turn adjustment screw 54 clockwise using a suitable screwdriver.
  • If the laser beam moves towards the right, turn adjustment screw 54 anticlockwise.
  • After adjusting, check the flushness with the cutting line again. If required, align the laser beam with the adjustment screw 52 again.

Aligning the Fine Scale

  • Bring the power tool into the chop and miter saw working position.
  • Turn the saw table 22 to the 0° detent 27. The lever 26 must be felt to engage in the detent.

Checking:
The 0° mark of the fine-scale 46 must be in alignment with the 0° mark of the scale 23.

Adjusting:

  • Remove the insert plate 24.
  • Loosen the screw 55 with the slotted screwdriver provided and align the fine-scale alongside the 0° marks.
  • Retighten the screw again.

Aligning the Angle Indicator (Vertically)

  • Bring the power tool into the chop and miter saw working position.
  • Turn the saw table 22 to the 0° detent 27. The lever 26 must be felt to engage in the detent.

Checking:
The angle indicator 47 must be in alignment with the 0° mark of scale 48.

Adjusting:

  • Loosen the screw 56 with the slotted screwdriver provided and align the angle indicator alongside the 0° mark.
  • Afterward, check to ensure that the adjustment made is correct for the 45° mark.
  • Retighten the screw again.

Aligning the Fence

  • Bring the power tool into the table saw working position.
  • Turn the saw table 22 to the 0° detent 27. The lever 26 must be felt to engage in the detent.

Operation as Table Saw

  • Before any work on the machine itself, pull the mains plug.

Working Position

If the power tool was used as a chop and mitre saw, then the following steps must be carried out before using as a table saw:

  • Bring the power tool into the chop and miter saw working position.
  • Loosen locking screw 44.
  • Pull the adjustable fence 31 completely outward.
  • Retighten the locking screw 44.
  • Pull the lower saw blade cover 66 out of the groove of the parallel guide 61.
  • Insert the lower saw blade cover 66 into the saw table 22. During operation as a table saw, the lower saw blade cover 66 must cover the bottom part of the saw blade.
  • Set the vertical bevel angle to 0° and tighten the lock lever 37.
  • Press release button 17 and slowly guide the tool arm by handle 18 downward until the transport safety-lock 38 can be pushed completely inward.

Preparing for Operation

Adjusting the Saw Blade Height
For safe operation, the correct working position of the saw blade 7 to the workpiece must be adjusted. The maximum workpiece height is 51 mm.

  • Loosen both clamping levers 68 below the saw table 59.
  • Tilt the protection guard 63 toward the rear to the stop and position your workpiece next to the saw blade.
  • Push the saw table down or pull it upward until the upper saw teeth of the saw blade project approx. 1 mm above the workpiece surface.
  • Hold the saw table in this position and retighten the clamping levers again.

Adjusting the Parallel Guide
The parallel guide 61 can be positioned to the right of the saw blade. The clearance indicator 69 indicates the clearance of the parallel guide to the saw blade on the scale 65.

  • Loosen the clamping knob 64.
  • This relieves guide 71 at the rear of the parallel guide.
  • Firstly, insert the parallel guide into the rear guide groove of the saw table.
  • Then position the parallel guide into the front guide groove of the saw table.
  • The parallel guide can be moved variably now.
  • Move the parallel guide until the clearance indicator 69 indicates the requested clearance to the saw blade.
  • To lock the parallel guide, push the clamping knob 64 downward again.

Make sure that the parallel guide is always parallel to the saw blade or that the sawblade/parallel guide clear-ance increases toward the rear. Otherwise, the danger is given that the workpiece is jammed between the saw blade and the parallel guide.

Starting Operation

Switching On

  • For starting the operation, press the green ON pushbutton 2 (I).

Switching Off

  • Press the red OFF pushbutton 1 (O).
  • To save energy, only switch the power tool on when using it.

Power Failure

The ON/OFF switch is a so-called non-voltage switch, which prevents the power tool from restarting after a power failure (e. g., when the mains plug is pulled during operation).

  • To restart the power tool, press the green ON pushbutton 2 again.

Working Advice

General Sawing Instructions

  • For all cuts, it must first be ensured that the saw blade at no time can come in contact with the stops or other machine parts.

Protect the saw blade against impact and shock. Do not subject the saw blade to lateral pressure.
Pay attention that the riving knife is in line with the saw blade. Do not saw warped/bent workpieces. The workpiece must always have a straight edge to face against the parallel guide. Always keep/store the push stick with the power tool.
Do not use the power tool for joining, grooving, or cutting slots. Long workpieces must be underlaid or supported at their free end. (see figure E)

Position of the Operator

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.

Observe the following instructions:

  • Hold the workpiece securely with both hands and press it firmly against the saw table, expecially when working without the guide.
  • When sawing small workpieces, use the hold-down stick provided.

Sawing

Sawing Straight Cuts

  • Adjust the parallel guide 61 to the requested cutting width.
  • Position the workpiece on the saw table in front of the blade guard 63.
  • Adjust the correct saw blade height
  • Make sure that the blade guard is positioned properly.
  • It must always face against the workpiece while sawing.
  • Switch on the machine.
  • Saw through the workpiece applying uniform feed.
  • Switch off the machine and wait until the saw blade has come to a complete stop.
Checking and Adjusting the Basic Adjustment
  • Before any work on the machine itself, pull the mains plug.

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 Clearance Indicator of the Parallel Guide

  • Use a workpiece or an object with an exactly defined width x. The length of the object should approximately correspond with the diameter of the saw blade.
  • Slide the object under the blade guard 63 and position it flushes to the saw blade.
  • Move the parallel guide 61 from the right side until it touches the object, and then lock the parallel guide in this position.

Checking:
The clearance indicator 69 must indicate the width x of the object on the scale 65.
Adjusting:

  • Loosen screw 70 with the slotted screwdriver provided and align the clearance indicator exactly to the width x.

Adjusting the Tension Force of the Parallel Guide
The tension force of the guide 71 on the parallel guide can decrease after frequent use.

  • Tighten the adjustment screw 72 until the parallel guide can be firmly affixed on the saw table again.

Aligning the Parallel Guide Parallel to the Saw Blade

  • Use a workpiece or an appropriate object with parallel edges. The length of the object should approximately corre-spond with the diameter of the saw blade.
  • Slide the object under the blade guard 63 and position it flushes to the saw blade.
  • Move the parallel guide 61 from right to left until it touches the object.
  • Checking: The parallel guide must be flush with the object over the complete length.
  • Adjusting: Remove the parallel guide from the saw table 59 and loosen the three screws 73 inside the glide pad of the parallel guide using a Phillips screwdriver.

Maintenance and Service

Maintenance and Cleaning

  • Before any work on the machine itself, pull the mains plug.
  • If the replacement of the supply cord is necessary, this has to be done by Bosch or an authorized Bosch service agent in order to avoid a safety hazard.

Cleaning
For safe and proper working, always keep the power tool and its ventilation slots clean. The retracting blade guard must always be able to move freely and retract automatically. Therefore, always keep the area around the retracting blade guard clean. Remove dust and chips after each working procedure by blowing out with compressed air or with a brush. Clean the lighting and laser unit (34, 19) regularly. To clean the laser lens cover 16, completely unscrew the screw. Afterward, pull the cover out of the casing alongside the retracting blade guard 20. (see figure h)
