GENERAL POWER TOOL SAFETY WARNINGS

WARNING

Read all safety warnings and all instructions. Failure

to follow the warnings and instructions 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

Ŷ Keep work area clean and well lit. Cluttered or dark

areas invite accidents.

Ŷ 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.

Ŷ Keep children and bystanders away while operating

a power tool. Distractions can cause you to lose

control.

ELECTRICAL SAFETY

Ŷ 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.

Ŷ 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.

Ŷ Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of
electric shock.

Ŷ 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.

Ŷ 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.

Ŷ 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

Ŷ 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.

Ŷ Use personal protective equipment. Always wear

eye protection. Protective equipment such as dust

mask, non-skid safety shoes, hard hat or hearing
protection used for appropriate conditions will reduce
personal injuries.

Ŷ 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.

Ŷ 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.

Ŷ Do not overreach. Keep proper footing and balance

at all times. This enables better control of the power

tool in unexpected situations.

Ŷ Dress properly. Do not wear loose clothing or

jewellery. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewellery or long

hair can be caught in moving parts.

Ŷ 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.

POWER TOOL USE AND CARE

Ŷ 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.

Ŷ 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.

Ŷ Disconnect the plug from the power source and/or

the battery pack 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.

Ŷ Store idle power tools out of the reach of children

1

Safety

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.

Ŷ Maintain power tools. 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.

Ŷ Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.

Ŷ 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.

BATTERY TOOL USE AND CARE

Ŷ 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.

Ŷ Use power tools only with specifically designated

battery packs. Use of any other battery packs may

create a risk of injury and fire.

Ŷ 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.

Ŷ 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.

SERVICE

Ŷ 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.

CIRCULAR SAW SAFETY WARNINGS

CUTTING PROCEDURES

Ŷ

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.

Ŷ Do not reach underneath the workpiece. The guard

cannot protect you from the blade below the workpiece.

Ŷ 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.

Ŷ Never hold piece being cut in your hands or across

your leg. Secure the workpiece to a stable platform.

It is important to support the work properly to minimize
body exposure, blade binding, or loss of control.

Ŷ Hold power tool by insulated gripping surfaces only

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.

Ŷ When ripping, always use a rip fence or straight

edge guide. This improves the accuracy of cut and

reduces the chance of blade binding.

Ŷ 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
eccentrically, causing loss of control.

Ŷ 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:

Ŷ 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;

Ŷ 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;

Ŷ 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.

Ŷ 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.

Ŷ 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.

Ŷ When restarting a saw in the workpiece, centre the

saw blade in the kerf and check that saw teeth are
not engaged into the material. If saw blade is binding,

it may walk up or kickback from the workpiece as the
saw is restarted.

Ŷ 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.

Ŷ Do not use dull or damaged blades. Unsharpened

or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.

Ŷ Blade depth and bevel adjusting locking levers

must be tight and secure before making cut. If blade

2

Safety

adjustment shifts while cutting, it may cause binding
and kickback.

Ŷ 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

Ŷ 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.

Ŷ 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.

Ŷ Lower guard may be retracted manually only for

special cuts such as “plunge cuts” and “compound
cuts”. Raise lower guard by retracting handle and as

soon as blade enters the material, the lower guard
must be released. For all other sawing, the lower guard
should operate automatically.

Ŷ Always observe that the lower guard is covering the

blade before placing 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.

ADDITIONAL SAFETY WARNINGS

Ŷ The dust produced when using the product may be

harmful to your health, inflammable, or explosive. Do
not inhale the dust. Use a dust extraction system,
and wear a suitable dust protection mask. Remove
deposited dust thoroughly, e.g., with a brush and
vacuum cleaner.

Ŷ Do not use any abrasive wheels.
Ŷ Use only blades specified in this manual, complying

with EN 847-1.

Ŷ Avoid overheating the blade tips. Do not use dull or

damaged blades. Do not force the tool.

Ŷ Do not use blades of larger or smaller diameter than

recommended.

Ŷ Wear ear protection.
Ŷ Clamp workpiece with a clamping device. Unclamped

workpieces can cause severe injury and damage.

Ŷ Thoroughly check the material to be cut, particularly

when using recycled wood, for foreign objects such as
nails, screws, and staples. If nails, screws, staples or
similar items contact the blade whilst cutting, the saw
will be damaged and severe injury to the operator or
others may occur.

Ŷ Do not touch the saw blade immediately after sawing.

The saw blade gets hot during sawing.

ADDITIONAL BATTERY SAFETY WARNINGS

WARNING

To reduce the risk of fire, personal injury, and product
damage due to a short circuit, never immerse your
tool, battery pack or charger in fluid or allow a fluid to
flow inside them. Corrosive or conductive fluids, such
as seawater, certain industrial chemicals, and bleach
or bleach-containing products, etc., can cause a short
circuit.

TRANSPORTING LITHIUM BATTERIES

Transport the battery in accordance with local and national
provisions and regulations.

Follow all special requirements on packaging and labelling
when transporting batteries by a third party. Ensure that
no batteries can come in contact with other batteries
or conductive materials while in transport by protecting
exposed connectors with insulating, non-conductive caps
or tape. Do not transport batteries that are cracked or
leaking. Check with the forwarding company for further
advice.

RESIDUAL RISKS

Even when the product is used as prescribed, it is still
impossible to completely eliminate certain residual risk
factors. The following hazards may arise and the operator
should pay special attention to avoid the following:

Ŷ Injury caused by kickback

– Read and understand the information in this manual.

Ŷ Injury caused by vibration

– Limit exposure. See Risk Reduction.

Ŷ Injury caused by dust

– Wear eye protection at all times. Wear appropriate

dust mask with suitable filters that can protect
against particles from the material being worked on.
Do not eat, drink, or smoke in the work area. Ensure
adequate ventilation.

Ŷ Electric shock

– The blade may contact hidden wiring causing

parts of the product to become live. Always hold
the product by the designated handles and take
care when blind-cutting into walls and floors where
cables may be hidden.

NOTE: When working on walls, ceilings, or floors, take
care to avoid electric cables and gas or water pipes.

Ŷ Injury from contact with the cutting blade

– The blades are sharp and will become hot during

use. Wear gloves when changing blades. Keep
hands away from the cutting area at all times. Never
hold workpiece being cut in your hands or across
your leg. Clamp the work piece whenever possible.

RISK REDUCTION

It has been reported that vibrations from handheld tools
may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling,
numbness, and blanching of the fingers, usually apparent
upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking, and work practices

3

Safety

are all thought to contribute to the development of these
symptoms. There are measures that can be taken by the
operator to possibly reduce the effects of vibration:

Ŷ Keep your body warm in cold weather. When operating

the product, wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major factor
contributing to Raynaud’s Syndrome.

Ŷ After each period of operation, exercise to increase

blood circulation.

Ŷ Take frequent work breaks. Limit the amount of

exposure per day.

If you experience any of the symptoms of this condition,
immediately discontinue use and see your doctor about
these symptoms.

WARNING

Injuries may be caused or aggravated by prolonged use
of a tool. When using any tool for prolonged periods,
ensure you take regular breaks.
