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.
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.

4 English 2264109 *2264109*
▶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.
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. 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 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.

*2264109* 2264109 English 5
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.
▶Maintain a firm grip with both hands 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.
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 the switch is released.

6 English 2264109 *2264109*
Riving knife function
▶Use the appropriate saw blade for the riving knife. For the riving knife to function, the body of the
blade must be thinner than the riving knife and the cutting width of the blade must be wider than the
thickness of the riving knife.
▶Adjust the riving knife as described in this instruction manual. Incorrect spacing, positioning and
alignment can make the riving knife ineffective in preventing kickback.
▶Always use the riving knife except when plunge cutting. The riving knife must be replaced after
plunge cutting. The riving knife causes interference during plunge cutting and can create kickback.
▶For the riving knife to work, it must be engaged in the workpiece. The riving knife is ineffective in
preventing kickback during short cuts.
▶Do not operate the saw if the riving knife is bent. Even a light interference can slow the closing rate of
a guard.
2.3 Additional safety instructions
Personal safety
▶Never tamper with or modify the product or accessories in any way.
▶Always hold the power tool with both hands on the grips provided. Keep the grips dry, clean and
free from oil and grease.
▶Wear ear protectors. Exposure to noise can cause hearing loss.
▶Respiratory protection must be worn if the power tool is used without a dust removal system for
work that creates dust.
▶Operate the power tool only together with the safety devices that belong to it.
▶Improve the blood circulation in your fingers by relaxing your hands and exercising your fingers
during breaks between working.
▶The power tool is not intended for use by inexperienced persons who have received no special
training.
▶Keep the power tool out of reach of children.
▶Do not switch the product on before it is at the workplace.
▶Remove the battery before storing or transporting the power tool.

▶Never press the drive spindle lock button while the saw blade is rotating.
▶Never direct the power tool toward persons.
▶Adjust the pressure applied to the saw blade and the material being cut so that the blade does not
stall, possibly causing kickback.
▶Avoid overheating the tips of the saw blade teeth.
▶When cutting plastic, melting of the plastic should be avoided.
▶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.
▶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.

*2264109* 2264109 English 7
▶Do not look directly into the light source (LED) of the product and do not aim the beam at other
persons’ faces. Risk of dazzling or eye damage.
▶Always engage the switch-on interlock before storing or transporting the saw. This prevents unintentional
starting of the product.
▶Risk of injury by falling tools and/or accessories. Before starting work, check that installed accessories
are secure.
Electrical safety
▶Before beginning work, check the working area (e.g. using a metal detector) to ensure that no
concealed electric cables or gas and water pipes are present. External metal parts of the power
tool may become live, for example, when an electric cable is damaged accidentally. This constitutes a
serious risk of electric shock.

4.2 Noise information and vibration values in accordance with EN 62841
The sound pressure and vibration values given in these instructions were measured in accordance with a
standardized test and can be used to compare one power tool with another. They can also be used for a
preliminary assessment of exposure.
The data given represent the main applications of the power tool. However, if the power tool is used for
different applications, with different accessory tools, or is poorly maintained, the data can vary. This can
significantly increase exposure over the total working period.
An accurate estimation of exposure should also take into account the times when the tool is switched off, or
when it is running but not actually being used for a job. This can significantly reduce exposure over the total
working period.
Identify additional safety measures to protect the operator from the effects of noise and/or vibration, for
example: maintaining the power tool and accessory tools, keeping the hands warm, organization of work
patterns.
