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
s
rdous
saw, they cannot be cut by the blade.
- Do not reach underneath the workpiece. The guard

cannot protect you from the blade below the workpiece.
- Adjust the cutting depth to the thickness of the
m
workpiece. Less than a full tooth of the blade teeth should
be visible below the workpiece.
es
- 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
them
exposure, blade binding, or loss of control.
- Hold the power tool by insulated gripping surfaces
only, when performing an operation where the cutting
cing
tool may contact hidden wiring or its own cord.
Contact with a "live" wire will also make exposed metal
use
parts of the power tool "live" and could give the operator
an electric shock.
- When ripping, always use a rip fence or straight edge
hat
guide. This improves the accuracy of cut and reduces the
chance of blade binding.
- 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.

Kickback causes and related warnings
ews, - kickback is a sudden reaction to a pinched, bound or

ained.
or use
ability
- 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.
- 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.
- 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.
- 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.
- Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
- 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.
- 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
- 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.
- 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.
- 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.
- 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.
