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.
Unmodied plugs and 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
extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of electric
shock.
f) 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.
3) PERSONAL SAFETY
a) 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
inuence 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 a 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 o-position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your nger on the
switch or energising power tools that have the switch on
invites accidents.
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
jewellery. Keep your hair and clothing 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
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
h) Do not let familiarity gained from frequent use of

SAFETY
GENERAL POWER TOOL SAFETY WARNINGS
-WARNING Read all safety warnings, instructions,
illustrations and specications provided with this
power tool. Failure to follow all instructions listed below may
result in electric shock, re 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.
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks which

11
contact hidden wiring or its own cord (cutting blades
contacting a “live” wire may make exposed metal parts
of the power tool “live” and could give the operator an
electric shock)
f) When ripping always use a parallel guide or straight
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
g) 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.
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.
2) 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 towards operator
• Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
a) Maintain a rm 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 backwards while the
blade is in motion or kickback may occur. Investigate
and take corrective actions to eliminate the cause of
blade binding. Avoid cutting nails or screws.
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
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
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 o. 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 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.
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 and accessories. Check for
misalignment or binding of moving parts, breakage
of parts and any other condition that may aect 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
account the working conditions and the work to be
performed. Use of the power tool for operations dierent
from those intended could result in a hazardous situation.
h) 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.
5) SERVICE
a) Have your power tool serviced by a qualied repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
SAFETY WARNINGS FOR CIRCULAR SAWS
1) CUTTING PROCEDURES
a) 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 can not be cut by the blade.
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 the workpiece 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 the insulated gripping
surfaces only, because the cutting blades may

EXPLANATION OF SYMBOLS ON TOOL
3Read the instruction manual before use
4Double insulation (no earth wire required)
5Do not dispose of the tool together with household waste
material
WHEN CONNECTING NEW 3-PIN PLUG (U.K. ONLY):
• Do not connect the blue (= neutral) or brown (= live) wire
in the cord of this tool to the earth terminal of the plug
•If for any reason the old plug is cut o the cord of this tool,
it must be disposed of safely and not left unattended
that can cause kickback.
1) 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.
Disconnect the plug, 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 should 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 oor.
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
• Inrush currents cause short-time voltage drops; under
unfavourable power supply conditions, other equipment
may be aected (if the system impedance of the power
supply is lower than 0.468 Ohm, disturbances are
unlikely to occur); if you need further clarication, you
may contact your local power supply authority
GENERAL
