Safety instructions

General Power Tool Safety Warnings
WARNING
Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all in-structions listed below may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cord-less) 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 sur-faces, 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 suit-able for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is un-avoidable, 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 in-juries.
• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or 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 in-jury.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing 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 ex-traction and collection facilities, ensure these are connected and properly used. Use of dust collection can re-duce dust-related hazards.
• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe in-jury within a fraction of a second.

Power tool use and care

• Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was de-signed.
• Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/or re-move the battery pack, if detachable, from the power tool before making any adjustments, changing 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 ac-count the working conditions and the work to be per-formed. Use of the power tool for operations different from those intended could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

Battery tool use and care

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

Service

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
• Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

Safety Warnings for Circular Saws
Cutting procedures

• DANGER: Keep hands away from cutting area and the blade. Keep your second hand on auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade.

• Do not reach underneath the workpiece. The guard can-not protect you from the blade below the workpiece.

• Adjust the cutting depth to the thickness of the work-piece. Less than a full tooth of the blade teeth should be visible below the workpiece.

• Never hold piece being cut in your hands or across your leg. Secure the workpiece to a stable platform. It is im-portant to support the work properly to minimize body ex-posure, blade binding, or loss of control.

• Hold the power tool by insulated gripping surfaces on-ly, 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 (dia-mond versus round) of arbour holes. Blades that do not match the mounting hardware of the saw will run eccentri-cally, 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, bound 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 bound 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 surface of 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 oper-ating procedures or conditions and can be avoided by tak-ing proper precautions as given below.

• Maintain a firm grip with both hands on the saw and po- sition 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 back-wards, but kickback forces can be controlled by the opera-tor, if proper precautions are taken.

• When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the saw mo-tionless in the material until the blade comes to a com-plete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in mo-tion or kickback may occur. Investigate and take correc-tive actions to eliminate the cause of blade binding.

• When restarting a saw in the workpiece, center the saw blade in the kerf and check that saw teeth are not en-gaged into the material. If saw blade is binding, it may walk up or kickback from the workpiece as the saw is re-started.

• Support large panels to minimize the risk of blade pinching and kickback. Large panels tend to sag under their own weight. Supports must be placed under the pan-el on both sides, near the line of cut and near the edge of the panel.

• Do not use dull or damaged blades. Unsharpened or im-properly 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 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.

Lower guard function

• Check lower guard for proper closing before each use. Do not operate the saw if lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If saw is accidentally dropped, lower guard may be bent. Raise the lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut.
• Check the operation of the lower guard spring. If the guard and the spring are not operating properly, they must be serviced before use. Lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
• The lower guard may be retracted manually only for special cuts such as “plunge cuts and angle cuts”. Raise  the lower guard by retracting the handle and as soon as the blade enters the material, release the lower guard. For all other sawing operations, the lower guard should operate automatically.
• Always observe that the lower guard is covering the blade before placing saw down on bench or floor. An un-protected, coasting blade will cause the saw to walk back-wards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after switch is released.

Additional safety warnings

• Do not reach into the chip ejector with your hands. They could be injured by rotating parts.
• Do not work overhead with the saw. In this manner you do not have sufficient control over the power tool.
• 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 explo-sion. Penetrating a water line causes property damage or may cause an electric shock.
• Do not operate the power tool stationary. It is not de-signed for operation with a saw table.
• Do not use high speed steel (HSS) saw blades. Such saw blades can easily break.
• Do not saw ferrous metals. Red hot chips can ignite the dust extraction.
• When working with the machine, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more secure with both hands.
• Secure the workpiece. A workpiece clamped with clamp-ing devices or in a vice is held more secure than by hand.
• Always wait until the machine has come to a complete stop before placing it down. The tool insert can jam and lead to loss of control over the power tool.

Noise/Vibration Information
Sound emission values determined according to EN 60745-2-5.
Typically the A-weighted noise levels of the product are: Sound pressure level 92 dB(A); Sound power level 103 dB(A). Uncertainty K =3 dB.

Wear hearing protection!

Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 60745:

• Cutting wood: ah=4.0 m/s2, K=1.5 m/s2,
• Cutting metal: ah=3.0 m/s2, K=1.5 m/s2.

The vibration level given in this information sheet has been measured in accordance with a standardised test given in EN 60745 and may be used to compare one tool with anoth-er. It may be used for a preliminary assessment of exposure. The declared vibration emission level represents the main ap- plications of the tool. However if the tool is used for different applications, with different accessories or insertion tools or is 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 sig-nificantly 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 pat-terns.

• Before any work on the machine itself, pull the mains plug.
• When mounting the saw blade, wear protective gloves. Danger of injury when touching the saw blade.
• Only use saw blades that correspond with the characteristic data given in the operating instructions.
• Do not under any circumstances use grinding discs as the cutting tool.

Selecting a Saw Blade
An overview of recommended saw blades can be found at the end of this manual.

Removal of the Saw Blade (see figure A)
For changing the cutting tool, it is best to place the machine on the face side of the motor housing.

• Press the spindle lock button 4 and keep it pressed.
• The spindle lock button 4 may be actuated only when the saw spindle is at a standstill. Otherwise, the power tool can be damaged.
• With the Hex key 6, unscrew the clamping bolt 18 turning in rotation direction .
• Tilt back the retracting blade guard 11 and hold firmly.
• Remove the clamping flange 19 and the saw blade 20 from the saw spindle 22.

Mounting the Saw Blade (see figure A)
For changing the cutting tool, it is best to place the machine on the face side of the motor housing.

• Clean the saw blade 20 and all clamping parts to be assembled.
• Tilt back the retracting blade guard 11 and hold firmly.
• Place the saw blade 20 on to the mounting flange 21. The cutting direction of the teeth (direction or arrow on saw blade) and the direction-of-rotation arrow on the blade guard 15 must correspond.
• Mount the clamping flange 19 and screw in the clamping bolt 18 turning in rotation direction . Observe correct mounting position of mounting flange 21 and clamping flange 19.
• Press the spindle lock button 4 and keep it pressed.
• With the Hex key 6, tighten the clamping bolt 18 turning in rotation direction . The tightening torque is between 6–9 Nm, which corresponds to hand tight plus ¼ turn.

Dust/Chip Extraction (see figures B–E)

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

• 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-treat-ment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.

  • As far as possible, use a dust extraction system suitable for the material.
  • 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.

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

Note: While sawing, always use the deflection tube 24 or the dust/chip box 25 so that you will not be hit by thrown about chips.
The deflection tube 24 can be used with or without dust/chip extraction. Depending on the application, turn the deflection tube 24 in such a manner that you are not hit by chips and insert it firmly into the sawdust ejector 16.

External Dust Extraction (see figure B)
Mount the vacuum hose 23 (accessory) on to the chip ejector 16. Connect the vacuum hose 23 to a vacuum cleaner (acces-sory). An overview for connecting to various vacuum cleaners can be found at the end of this manual.
The machine can be plugged directly into the receptacle of a Bosch all-purpose vacuum cleaner with remote starting con-trol. The vacuum cleaner starts automatically when the ma-chine is switched on.
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.

Integrated Dust Extraction (see figures C–E)
For smaller jobs, the dust/chip box 25 can be used with the slider 26 shut. For larger jobs, the slider 26 should be open so that the chips can fall out.
Insert the dust/chip box 25 firmly into the chip ejector 16.
Empty the dust/chip box 25 in time to maintain optimum effi-ciency.
To empty the dust/chip box 25, pull it off of the chip ejector 16. Press the slider 26 upward, turn the dust/chip box 25 aside and empty it.
Before reattaching, clean the connection sleeve of the dust/chip box 25.

Operation

Operating Modes

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

Adjusting the Cutting Depth (see figure F)

• Adjust the cutting depth to the thickness of the work-piece. Less than a full tooth of the blade teeth should be visible below the workpiece.

Loosen the clamping lever 27. For a smaller cutting depth, pull the saw away from the base plate 12; for a larger cutting depth, push the saw toward the base plate 12. Adjust the de-sired cutting depth at the cutting-depth scale. Tighten the clamping lever 27 again.

Adjusting the Cutting Angle
Loosen the wing bolts 7 and 14. Tilt the saw sidewards. Ad-just the desired measure on the scale 5. Tighten the wing bolts 7 and 14 again.
Note: For bevel cuts, the cutting depth is smaller than the set-ting indicated on the cutting-depth scale 28.

Cutting Marks (see figure G)
(PKS 55 A/PKS 55-2 A/PKS 66 A/PKS 66 AF/
PKS 66-2 AF)
The “CutControl” 9 viewing window, which folds out to the front, is used for precise guiding of the circular saw alongside the cutting line on the workpiece. The “CutControl” 9 viewing window has a mark each for right-angled cuts and for 45° cuts.
The 0° cutting mark 30 indicates the position of the saw blade for right- angled cuts. The 45° cutting mark 29 indicates the position of the saw blade for 45° cuts.

For precise cuts, position the circular saw against the work-piece as shown in the figure. It is best to carry out a trial cut.

Cutting Marks (PKS 55)
The 0° cutting mark 30 indicates the position of the saw blade for right- angled cuts. The 45° cutting mark 29 indicates the position of the saw blade for 45° cuts.

For precise cuts, position the circular saw against the work-piece as shown in the figure. It is best to carry out a trial cut.

Starting Operation

• Observe correct mains voltage! The voltage of the pow-er source must agree with the voltage specified on the nameplate of the machine. Power tools marked with 230 V can also be operated with 220 V.

Switching On and Off
To start the machine, first push the lock-off button for the On/Off switch 1 and then press the On/Off switch 2 and keep it pressed.
To switch off the machine, 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.
To save energy, only switch the power tool on when using it.

Working Advice

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

Protect saw blades against impact and shock.
Guide the machine evenly and with light feed in the cutting direction. Excessive feed significantly reduces the service life of the saw blade and can cause damage to the power tool.
Sawing performance and cutting quality depend essentially on the condition and the tooth form of the saw blade. There-fore, use only sharp saw blades that are suited for the material to be worked.

Sawing Wood
The correct selection of the saw blade depends on the type and quality of the wood and whether lengthway or crossway cuts are required.
When cutting spruce lengthways, long spiral chips are formed.
Beech and oak dusts are especially detrimental to health. Therefore, work only with dust extraction.

Sawing Non-ferrous Metals
Note: Use only a sharp saw blade that is suitable for non-ferrous metals. This ensures a clean cut and prevents blade binding.
Guide the switched on power tool against the workpiece and carefully start the cut. Continue the cut with low feed and without interruption.
When sawing profiles, always begin the cut from the narrow side; when sawing U-profiles, never start the cut from the open side. Support long profiles in order to avoid blade bind-ing and kickback of the power tool.

Sawing with Parallel Guide (see figure H)
The parallel guide 10 enables exact cuts along a workpiece edge and cutting strips of the same dimension.
Loosen wing bolt 8 and slide the scale of the parallel guide 10 through the guide in the base plate 12. Adjust the desired cut-ting width as the scale setting at the respective cutting mark 30 or 29; see Section “Cutting Marks”. Tighten wing bolt 8 again.

Sawing with Guide Rail (see figures I–K)
The guide rail 31 is used to carry out straight cuts.
The adhesive coating prevents the guide rail from slipping and protects the surface of the workpiece.
The guide rail 31 can be extended. For this, turn around both guide rails 31 by 180° and connect both guide rails 31 by in-serting them. Press button 32 to lock the guide rails. To disas-semble the guide rails, press the opposite button 32 and pull the guide rails 31 apart.
The guide rail 31 has two marks on the top side. The side with the “90°” mark is used for right-angled cuts, and the side with the “45°” mark is used for all other mitre cuts.
The rubber lip on the guide rail acts as a splinter guard for 90° and 45° cuts; it prevents fraying of the surface while sawing wooden materials.

Upon initial sawing, the rubber lip is adapted to your circular saw, and slightly cut off in this process.
Note: On the workpiece side where the cut is being started, the guide rail 31 must always face flush against the work-piece, and may not project beyond it.
Should the guide rail 31 project beyond the workpiece end, do not rest the circular saw on the guide rail 31 without hold-ing the circular saw. The guide rail 31 is made of plastic and cannot hold the circular saw.
Fasten the guide rail 31 to the workpiece using the special screw clamps 33. Take care that the cam on the inside of the screw clamp 33 is seated in the corresponding recess of the guide rail 31.
Switch the machine on and guide it in the cutting direction ap-plying moderate and steady feed.

Maintenance and Service

Maintenance and Cleaning

• Before any work on the machine itself, pull the mains plug.
• For safe and proper working, always keep the machine and 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 by blowing out with compressed air or with a brush.
Saw blades that are not coated can be protected against cor-rosion with a thin coat of acid-free oil. Before use, the oil must be removed again, otherwise the wood will become soiled.
Resin and glue residue on the saw blade produces poor cuts. Therefore, clean the saw blade immediately after use.
If the replacement of the supply cord is necessary, this has to be done by Bosch or an authorized Bosch service agent in or-der to avoid a safety hazard.
