General Power Tool Safety Warnings

WARNING Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury. Save all warnings and instructions for future reference. The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work area safety

• Keep 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 personal 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 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 energising 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 jewellery. 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 extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce 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 injury within a fraction of a second.

Power tool use and care

• Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
• Do not use the power tool if the switch does not turn 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 remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
• Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

Service

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Safety instructions for circular saws

Cutting procedures

• DANGER: Keep hands away from cutting area and the blade. If both hands are holding the saw, they cannot be cut by the blade.
• Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece.
• Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth should be visible below the workpiece.
• Never hold the workpiece in your hands or across your leg while cutting. Secure the workpiece to a stable platform. It is important to support the work properly to minimise body exposure, blade binding, or loss of control.
• Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will also make exposed metal parts of the power tool “live” and could give the operator an electric shock.
• When ripping always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of blade binding.
• Always use blades with correct size and shape (diamond versus round) of arbour holes. Blades that do not match the mounting hardware of the saw will run offcentre, causing loss of control.
• Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation.

Kickback causes and related warnings

• kickback is a sudden reaction to a pinched, jammed or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece toward the operator;
• when the blade is pinched or jammed tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator;
• if the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surfaceof the wood causing the blade to climb out of the kerf and jump back toward the operator. Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.
• Maintain a firm grip on the saw and position your arms to resist kickback forces. Position your body to either side of the blade, but not in line with the blade. Kickback could cause the saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions are taken.
• When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion or kickback may occur. Investigate and take corrective actions to eliminate the cause of blade binding.
• When restarting a saw in the workpiece, centre the saw blade in the kerf so that the saw teeth are not engaged into the material. If a saw blade binds, it may walk up or kickback from the workpiece as the saw is restarted.
• Support large panels to minimise the risk of blade pinching and kickback. Large panels tend to sag under their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel.
• Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback.
• Blade depth and bevel adjusting locking levers must be tight and secure before making the cut. If blade adjustment shifts while cutting, it may cause binding and kickback.
• Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback. Guard function
• Check the guard for proper closing before each use. Do not operate the saw if the guard does not move freely and enclose the blade instantly. Never clamp or tie the guard so that the blade is exposed. If the saw is accidentally dropped, the guard may be bent. Check to make sure that the guard moves freely and does not touch the blade or any other part, in all angles and depths of cut.
• Check the operation and condition of the guard return spring. If the guard and the spring are not operating properly, they must be serviced before use.The guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
• Assure that the base plate of the saw will not shift while performing a “plunge cut”. Blade shifting sideways will cause binding and likely kick back.
• Always observe that the guard is covering the blade before placing the saw down on bench or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after switch is released

Cut-off machine safety warnings

• The guard provided with the tool must be securely attached to the power tool and positioned for maximum safety, so the least amount of wheel is exposed towards the operator. Position yourself and bystanders away from the plane of the rotating wheel. The guard helps to protect operator from broken wheel fragments and accidental contact with wheel.
• Use only bonded reinforced or diamond cut-off wheels for your power tool. Just because an accessory can be attached to your power tool, it does not assure safe operation.
• The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fly apart.
• Wheels must be used only for recommended applications. For example: do not grind with the side of cutoff wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter.
• Always use undamaged wheel flanges that are of correct diameter for your selected wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage.
• Do not use worn down reinforced wheels from larger power tools. Wheels intended for a larger power tool are not suitable for the higher speed of a smaller tool and may burst.
• The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
• The arbour size of wheels and flanges must properly fit the spindle of the power tool. Wheels and flanges with arbour holes that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
• Do not use damaged wheels. Before each use, inspect the wheels for chips and cracks. If power tool or wheel is dropped, inspect for damage or install an undamaged wheel. After inspecting and installing the wheel, position yourself and bystanders away from the plane of the rotating wheel and run the power tool at maximum no load speed for one minute. Damaged wheels will normally break apart during this test time.
• Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and shop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
• Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken wheel may fly away and cause injury beyond immediate area of operation.
• Hold the power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
• Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning wheel.
• Never lay the power tool down until the accessory has come to a complete stop. The spinning wheel may grab the surface and pull the power tool out of your control.
• Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body.
• Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and excessive  accumulation of powdered metal may cause electrical hazards.
• Do not operate the power tool near flammable materials. Sparks could ignite these materials.
• Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

Kickback and related warnings

Kickback is a sudden reaction to a pinched or snagged rotating wheel. Pinching or snagging causes rapid stalling of the rotating wheel which in turn causes the uncontrolled power tool to be forced in the direction opposite of the wheel’s rotation at the point of the binding. For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on directionof the wheel’s movement at the point of pinching. Abrasive wheels may also break under these conditions. Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.

• Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken.
• Never place your hand near the rotating accessory. Accessory may kickback over your hand.
• Do not position your body in line with the rotating wheel. Kickback will propel the tool in direction oppositeto the wheel’s movement at the point of snagging.
• Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback.
• Do not attach a saw chain, woodcarving blade, segmented diamond wheel with a peripheral gap greater than 10 mm or toothed saw blade. Such blades create frequent kickback and loss of control.
• Do not “jam” the wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage.
• When wheel is binding or when interrupting a cut forany reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate and take corrective action to eliminate the cause of wheel binding.
• Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece.
• Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel.
• Use extra caution when making a “pocket cut” into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.

Additional Safety Information

Wear safety goggles.

Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.

• Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property damage or may cause an electric shock.
• Do not touch the cutting disc after use before it has cooled. The cutting disc becomes very hot during use.
• Hold the power tool firmly with both hands and make sure you have a stable footing. The power tool can be more securely guided with both hands.

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 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.

• Use a dust extractor when working with stone. The dust extractor must be approved for extracting stone dust. Use of this equipment can reduce the risks posed by dust.
• Do not allow the chip ejector to come into contact with your hands. You may be injured by rotating parts.
• Do not use the saw above the level of your head. Doing so will mean you have inadequate control of the power tool.
• Do not operate the power tool when stationary . It is not suitable for operation with a saw table.
• Do not use HSS saw blades. Such saw blades can easily
• Do not saw any ferrous metals. Hot chips may ignite the dust extractor.

Technical Data

The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-specific models.

Noise/vibration information

Noise emission values determined according to Typically, the A-weighted noise level of the power tool is: Sound pressure level 83 dB(A); sound power level 94 dB(A). Uncertainty K = 5 dB.

Wear hearing protection!

Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 62841-2-5:

• Sawing wood: ah = 2.5 m/s2, K = 1.5 m/s2
• Sawing metal: ah = 2.5 m/s2, K = 1.5 m/s2

Noise emission values determined according to EN 60745-2-22. Typically, the A-weighted noise level of the power tool is: Sound pressure level 97 dB(A); sound power level 108 dB(A). Uncertainty K = 3 dB. Wear hearing protection! Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 60745-2-22:

• Cutting tiles: ah = 2.5 m/s2, K = 1.5 m/s2

The vibration level and noise emission value given in these instructions have been measured in accordance with a standardised measuring procedure and may be used to compare power tools. They may also be used for a preliminary estimation of vibration and noise emissions. The stated vibration level and noise emission value represent the main applications of the power tool. However, if the power tool is used for other applications, with different application tools or is poorly maintained, the vibration level and noise emission value may differ. This may significantly increase the vibration and noise emissions over the total working period. To estimate vibration and 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 vibration and noise emissions over the total working period. Implement additional safety measures to protect the operator from the effects of vibration, such as servicing the power tool and application tools, keeping their hands warm, and organising workflows correctly.

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.

External dust extraction (see figure E)

Push the dust extraction adapter (9) into the chip ejector (20) and turn the dust extraction adapter (9) in the direction of the arrow until you feel it click into place. Connect a dust extraction hose (17) (accessory) to the dust extraction adapter (9). Connect the dust extraction hose (17) to a dust extractor (accessory). You will find an overview of how to connect various dust extractors at the end of these operating instructions. The power tool can be directly connected to the socket of a
Bosch all-purpose dust extractor with remote starter. This dust extractor is started up automatically when the power tool is switched on. 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 designed for this purpose.

Operation

• Pull the plug out of the socket before carrying out any work on the power tool.

Operating modes

Setting the cutting depth (see figure B)

• Adapt the cutting depth to the thickness of the workpiece. A space of less than the height of one full tooth should be visible under the workpiece. Undo the screw for setting the cutting depth (8) in rotational direction ➊. Use the slider (5) to set the required cutting depth (material thickness + tooth height of the application tool) on the cutting depth scale ➋. Tighten the screw for setting the cutting depth (8) in rotational direction ❸.

Start-up

• 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. Power tools marked with 230 V can also be operated with 220 V.
• Products that are only sold in AUS and NZ: Use a residual current device (RCD) with a nominal residual current of 30 mA or less.

Switching on/off (see figure C)

To start the power tool, first press the lock-off switch (1), then press and hold the on/off switch (2). Pressing the lock-off switch (1) also unlocks the plunge function and allows the power tool to be pushed down. This causes the application tool to plunge into the workpiece. Raising the power tool causes it to spring back into the starting position and the plunge function locks again. To switch off the power tool, release the on/off switch (2).
Note: For safety reasons, the on/off switch (2) cannot be locked; it must remain pressed during the entire operation. Practical advice

• Pull the plug out of the socket before carrying out any work on the power tool. The width of cut varies depending on the saw blade used. Protect saw blades against shock and impact. Guide the power tool evenly, pushing it gently in the cutting direction. Applying too much pressure to the power tool when moving it in the cutting direction significantly reduces the service life of the application tools and can damage the power tool. The sawing performance and the quality of the cut essentially depend on the condition and the tooth shape of the saw blade. This is why you should only use sharp saw blades that are suitable for the material being machined.

Sawing wood

Choosing the right saw blade depends on the wood type, wood quality and whether cuts with or against the grain are required. Making cuts in spruce with the grain produces long, spiralshaped chips. This can lead to the chip ejector (20) becoming clogged. Beech and oak dust is especially detrimental to health. Therefore, work only with dust extraction.

Sawing Plastic

Note: Sawing plastic, in particular PVC, produces long, spiral-shaped chips that can be electrostatically charged. This can lead to the chip ejector (20) becoming clogged. Therefore, you should not work without dust extraction. Switch on the power tool and bring it into contact with the workpiece, sawing it carefully. Then continue working quickly and without interruption so that the saw teeth do not become stuck as quickly.

Sawing non-ferrous metal

Note: Only use a sharp saw blade that is suitable for non-ferrous metal. This guarantees a clean cut and will prevent the saw blade from jamming. Switch on the power tool and bring it into contact with the workpiece, sawing it carefully. Then continue working with less feed and without interruption. For profiles, always begin the cut on the narrow side; for Ushaped profiles, never begin the cut on the open side. Support long profiles to prevent the saw blade jamming and the power tool kicking back.

Cutting Tiles

• When cutting tiles, take into account the statutory provisions and recommendations of the material manufacturer. The diamond cutting disc must be approved for cutting tiles. Suitable diamond cutting discs are available from Bosch.
• Diamond cutting discs become very hot while working; do not touch them until they have cooled. The power tool can become very hot near the diamond cutting disc. For this reason, allow it to cool down between two cuts.
• Tiles may only be cut dry and with dust extraction. The dust extractor must be approved for extracting stone dust. Suitable dust extractors are available from Bosch.

Plunge cuts (see figure D)

The marks on the base plate indicate the cutting edges on the workpiece at the maximum cutting depth. Place the base plate (3) on the work surface. Make sure that the rear mark on the base plate is in line with the start of the cutting line.

• Switch on the power tool and wait for the saw blade (14) to reach its operating speed.
• Slowly plunge the saw blade (14) into the workpiece. Plunging the saw blade in too quickly can result in kickback. Guide the power tool along the cutting line. Do not pull the power tool backwards!
• When you reach the end of the cutting line, lift the power tool off the workpiece and leave it switched on for a few more seconds.

Sawing with an auxiliary guide (see figure E)

For working on large workpieces or for cutting straight edges, you can securely fasten a board or rail to the workpiece as an auxiliary guide. The circular saw can be guided along the path of this auxiliary guide with the base plate.

Cut marks (see figure E)

The viewing window for “CutControl” (7), which folds out to the front, allows the power tool to be guided precisely along the cutting line that is applied to the workpiece. The cut mark (19) indicates the position of the application tool when making a right-angled cut.For a precise cut, place the power tool against the workpiece as shown in the figure. We recommend making a test cut.

Maintenance and Service

Maintenance and cleaning

• Pull the plug out of the socket before carrying out any work on the power tool.
• To ensure safe and efficient operation, always keep the power tool and the ventilation slots clean.

In order to avoid safety hazards, if the power supply cord needs to be replaced, this must be done by Bosch or by an after-sales service centre that is authorised to repair Bosch power tools. The protective guard (6) must always be able to move freely and be shut. It is therefore important to keep the area around the protective guard clean at all times. Remove dust and chips by blowing out with compressed air or using a brush. Non-coated saw blades can be protected against corrosion using a thin layer of acid-free oil. Remove the oil again before sawing as failure to do so will stain the wood. Resin or glue residue on the saw blade has a detrimental effect on the quality of the cut. You should therefore clean saw blades straight after use. Remove the clamping devices after completing the work and clean all clamping elements as well as the protective guard. Store and handle the accessories carefully.
