2 Safety
2.1 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.
*2360868* 2360868 English 3
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.
4 English 2360868 *2360868*
▶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.
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 behaviour 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 (265 °F) 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.
2.2 Safety instructions for all saws
Cutting procedures
▶DANGER: Keep hands away from cutting area and 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. 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 off-centre, 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 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 operating procedures or conditions and can be avoided
by taking proper precautions as given below.
*2360868* 2360868 English 5
▶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.
Lower guard function
▶Check the lower guard for proper closing before each use. Do not operate the saw if the lower
guard does not move freely and close instantly. Never clamp or tie the lower guard into the open
position. If the saw is accidentally dropped, the 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
"compound cuts". Raise the lower guard by the retracting handle and as soon as the blade enters
the material, the lower guard must be released. For all other sawing, the lower guard should operate
automatically.
▶Always observe that the lower 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.
2.3 Additional safety instructions
Personal safety
▶Never tamper with or modify the product or accessories in any way.
▶Operate the power tool only together with the safety devices that belong to it.
▶Check that the clamping flange is securely and correctly installed each time before putting the product
into operation.
▶If you use the power tool without a dust extractor, always wear light respiratory protection when
undertaking work that creates dust.
▶Wear ear protectors. Exposure to noise can cause hearing loss.
▶Take breaks between working and do physical exercises to improve the blood circulation in your fingers.
Exposure to vibration during long periods of work can lead to disorders of the blood vessels and nervous
system in the fingers, hands and wrists.
▶The power tool is not intended for use by debilitated persons who have received no special training.
▶Do not switch the power tool on until it is at the workplace and has been brought to its working position.
▶Remove the battery if a problem occurs with the power tool, whenever you change accessory tools or
accessories and before storing or transporting the power tool.
▶Do not attempt to brake the power tool by applying lateral pressure to the saw blade.
▶Before inserting the battery, check that the saw is switched off and that the switch-on interlock is
activated. In this way you avoid injuries due to unintentional starting of the power tool.
▶While the power tool is running, do not touch the clamping flange or the clamping screw.
▶Before you lay down the power tool, wait until the power tool has come to a complete stop.
▶Before changing the accessory tool, wait until the power tool has cooled down.
▶Never press the drive spindle lock button while the saw blade is rotating.
6 English 2360868 *2360868*
▶Never direct the power tool toward persons.
▶The switch-on interlock must always be activated whenever you change accessories or the battery, for
transport and when you are going to stow the power tool away.
▶Always use a saw blade suitable for the material and the condition of the workpiece.
▶Bring the saw blade into contact with the workpiece only when the circular saw is switched on.
▶Adapt forward pressure to the saw blade and the material being cut. In this way you prevent the saw
blade from stalling and possibly causing kickback.
▶Avoid overheating the tips of the saw blade teeth.
▶Before beginning work, check all the teeth of the saw blade for damage or missing tips. Use only saw
blades with all teeth intact and complete.
▶The rated speed of the accessory tool must be at least equal to the maximum speed marked on the
power tool. Accessories running faster than their rated speed can disintegrate and fly apart.
▶Do not work in an environment heavily contaminated with dust.
▶Dust produced by grinding, sanding, cutting and drilling can contain dangerous chemicals. Some
examples are: lead or lead-based paints; brick, concrete and other masonry products, natural stone
and other products containing silicates; certain types of wood, such as oak, beech and chemically
treated wood; asbestos or materials that contain asbestos. Determine the exposure of the operator and
bystanders by means of the hazard classification of the materials to be worked. Implement the necessary
measures to restrict exposure to a safe level, for example by the use of a dust collection system or by
the wearing of suitable respiratory protection. The general measures for reducing exposure include:
▶working in an area that is well ventilated,
▶avoidance of prolonged contact with dust,
▶directing dust away from the face and body,
▶wearing protective clothing and washing exposed areas of the skin with water and soap.
▶Always wear a dust mask that meets the requirements of the application.
▶Before starting work, check the hazard class of the dust that will be produced when working. Use an
industrial vacuum cleaner with an officially approved protection classification in compliance with locally
applicable dust protection regulations.
▶Comply with national health and safety requirements.
▶Use clamps or some other practical means to secure the workpiece and keep it in a stable position.
Attempting to stabilize the workpiece by hand or with your body is inadequate and can result in loss of
control. Do not have the workpiece held in position by a helper.
▶Do not look directly into the light source (LEDs) incorporated in the power tool and do not direct the light
at other persons’ faces.
▶Risk of injury by falling tools and/or accessories. Before starting work, check that installed accessories
are secure.
▶Before beginning work, check the guard for damage. Use the product only when the guard is undamaged.
▶When sawing through the workpiece, ensure to protect persons and the work area on the other side.
While sawing is in progress, parts of the workpiece can fall and lead to injuries.
▶Never cut into unknown materials and keep the line of cut above and below the workpiece free of
obstacles. The product can kick back if the saw blade comes into contact with an obstructing object.
▶Metal cuttings are sharp and can lead to injuries. Keep your clothing closed so that cuttings cannot find
their way into your gloves, shoes or other parts of your clothing.
▶Pay attention to the direction in which the metal chips fly. The chips are hot and can lead to fire, burns
and cut injuries. Replace the saw blade when you notice that spark formation increases.
▶The chip collector can become very hot. Always wear protective gloves when emptying or removing the
chip collector.
Electrical safety
▶Before beginning work, check the working area (e.g. using a detector) to ensure that no concealed
electric cables or gas and water pipes are present. External metal parts of the power tool can become
live, for example if you accidentally damage electric wiring. This causes an increased risk of electric
shock.
2.4 Careful handling and use of batteries
▶Comply with the following safety instructions for the safe handling and use of Li-ion batteries.
Failure to comply can lead to skin irritation, severe corrosive injury, chemical burns, fire and/or explosion.
▶Use only batteries that are in perfect working order.
*2360868* 2360868 English 7
▶Treat batteries with care in order to avoid damage and prevent leakage of fluids that are extremely
harmful to health!
▶Do not under any circumstances modify or tamper with batteries!
▶Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C
(176 °F).
▶Never use or charge a battery that has suffered an impact or been damaged in any other way. Check
your batteries regularly for signs of damage.
▶Never use recycled or repaired batteries.
▶Never use the battery or a battery-operated power tool as a striking tool.
