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.
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.

CUTTing PROCEDUREs


DANGER:
a ) 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 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 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.

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.
ʵ 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.
ʵ 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 minimize 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 should be retracted manually
only for special cuts such as "plunge cuts"
