General Power Tool Safety Warnings
WARNING! Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in elec-
Save all warnings and instructions for future reference.
The term ″power tool″ in the warnings refers to your mains-operat-
ed (corded) power tool or battery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark ar-
eas invite accidents.
b) Do not operate power tools in explosive atmospheres,
dust. Power tools create sparks which may ignite the dust
or fumes.
c) Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
2) Electrical safety
a) 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.
matching outlets will reduce risk of electric shock.
b) 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.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric
shock.
d) 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.
e) When operating a power tool outdoors, use an exten-
sion cord suitable for outdoor use. Use of a cord suit-
able for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location isunavoid-
able, use a residual current device (RCD) protected
supply. Use of an RCD reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not use a
of drugs, alcohol or medication. A moment of inattention
while operating power tools may result in serious personal
injury.
b) 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.
c) Prevent unintentional starting. Ensure the switch is
in the off-position before connecting to power source
.lootehtgniyrracropugnikcip,kcapyrettabro/dna
Carrying power tools with your finger on the switch or
energising power tools that have the switch on invites ac-
cidents.
d) 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.
e) Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
f) Dress properly. Do not wear loose clothing or jewel-
lery. Keep your hair, clothing and gloves away from
moving parts. Loose clothes, jewellery or long hair can be
caught in moving parts.
g) If devices are provided for the connection of dust ex-
traction and collection facilities, ensure these are con-
nected and properly used. Use of dust collectioncan
reduce dust-related hazards.
4) Power tool use and care
a) 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.
b) 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.
c) 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.
d) 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.
e) Maintain power tools. Check for misalignment or bind-
ing 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.
f) Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to bind
and are easier to control.
g) 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.
5) Service
a) 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.

b) Do not reach underneath the workpiece. The guard cannot
protect you from the blade below the workpiece.
c) 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.
d) 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.
e) Hold the power tool by insulated gripping surfaces only,
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.
f) When ripping, always use a rip fence or straight edge
guide. This improves the accuracy of cut and reduces the
chance of blade binding.
g) Always to use only blade diameter(s) in accordance with
the markings.
h) 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.
i) Do not use any abrasive wheels for this saw.
j) With provided blade, users can use it to cut wood and
plastic materials. Please note to avoid overheating the
blade tips and avoid melting the plastic.
k) Dust collection system
A dust extraction outlet has been supplied with the tool.
Connect it to user’s dust collector.When used correctly it can
help remove dust, chips and cutting debris away from the
cutting area.
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 operating
procedures or conditions and can be avoided by taking proper
precautions as given below.
a) 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.
b) 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
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.

motion or kickback may occur. Investigate and take corrective
actions to eliminate the cause of blade binding.
c) 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.
d) 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.
e) Do not use dull or damaged blades. Unsharpened or
improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
f) 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.
g) 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
a) 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.
b) 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.
c) 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.
d) 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.
