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 instruc-
tions 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.

4 English 2264106 *2264106*
▶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.

*2264106* 2264106 English 5
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.
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

6 English 2264106 *2264106*
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.

*2264106* 2264106 English 7
▶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.
▶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.

8 English 2264106 *2264106*
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.
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

*2264106* 2264106 English 9
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.

▶Do not touch the clamping flange or the clamping screw while the power
tool is running.
▶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.

10 English 2264106 *2264106*
▶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.
▶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 transport lock 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.
