The term “power tool” in the warnings refers to your mains-
operated (corded) power tool or battery-operated (cordless)
powertool.
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 flammable
liquids, gases or 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.
Electrical safety
d ) 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.
e ) 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.
f ) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electricshock.
g ) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool. Keep

h ) 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.
i ) 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
j ) 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.
k ) 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.
l ) 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.
m ) 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.
n ) Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power tool
in unexpectedsituations.
o ) 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.
p ) 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
q ) 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.
r ) 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.
s ) 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.
t ) 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.
u ) 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.
v ) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are less
likely to bind and are easier tocontrol.
w ) 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
x ) 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.
y ) Use power tools only with specifically designated
battery packs. Use of any other battery packs may create
a risk of injury andfire.
z ) 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.
aa )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
ab )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.
Additional Specific Safety Rules
Safety Instructions for All Saws
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 cannot 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 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 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
shock the operator.
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 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.
Causes and Operator Prevention
of Kickback
• 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 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 making a “plunge cut” into
existing walls or other blind areas. The protruding
blade may cut objects that can cause kickback.
Safety Instructions for Plunge-Type Saws
a ) Check guard for proper closing before each use. Do
not operate the saw if guard does not move freely
and enclose the blade instantly. Never clamp or tie
the guard with the blade exposed. If saw is accidentally
dropped, guard may be bent. Check to make sure that
guard moves freely and does not touch the blade or any
other part, in all angles and depths of cut.
b ) 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. Guard may operate sluggishly due to damaged parts,
gummy deposits, or a build-up of debris.
c ) Assure that the guide plate of the saw will not shift
while performing the “plunge cut” when the blade
bevel setting is not at 90°. Blade shifting sideways will
cause binding and likely kickback.
d ) Always observe that the 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 Instructions for All Saws
with Riving Knife
a ) Use the appropriate riving knife for the blade being
used. For the riving knife to work, it must be thicker than
the body of the blade but thinner than the tooth set of the
blade.
b ) Adjust the riving knife as described in this
instruction manual. Incorrect spacing, positioning
and alignment can make the riving knife ineffective in
preventingkickback.
c ) Always use the riving knife except when plunge
cutting. Riving knife must be replaced after plunge
cutting. Riving knife causes interference during plunge
cutting and can create kickback.
d ) For the riving knife to work, it must be engaged in
the workpiece. The riving knife is ineffective in preventing
kickback during short cuts.
e ) Do not operate the saw if riving knife is bent. Even a
light interference can slow the closing rate of a guard.
