[] 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°
I_ 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 workpiece. Less than a full tooth of the
blade teeth should be visible below the workpieceo
[] 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
[] Hold power tools by insulated gripping surfaces 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 tool "live" and shock the operator.
[] When ripping, always use a rip fence or straight edge guide. This improves the accuracy
of cut and reduces the chance of blade binding
[] Always use blades with the correct size and shape (diamond versus round) of arbor
holes. Blades that do not match the mounting hardware of the saw will run erratically, causing
loss of control°
[] 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.
[] If the power supply cord is damaged, it must be replaced only by the manufacturer or by an
authorized service center to avoid risk
CAUSES AND OPERATOR PREVENTION OFKICKBACK:
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 kerr 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 misuse and/
or incorrect operating procedures or conditions and can be avoided by taking proper precautions,
as given below:
[] 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, center the saw blade in the kerf and check that
saw teeth are not engaged into the material. If saw is binding, it may walk up or kickback
from the workpiece as the saw is restarted
m 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.
[] 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.
9

[] 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_
[] Check lower guard for proper closing before each use. Do not operate 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
blade guard with the retracting handle. Make sure it moves freely and does not touch the blade
or any other part, in alt 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 buildup of debris.
[] Lower guard should be retracted manually only for special cuts such as "plunge cuts"
and "compound cut." Raise lower blade guard by retracting handle. 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 the 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,,
[] Know your power tool. Read operator's manual carefully. Learn its applications and
limitations, as well as the specific potential hazards related to this tool. Following this
rule will reduce the risk of electric shock, fire or serious injury.
[] Always wear safety glasses with side shields. Everyday glasses have only impact resistant
lenses. They are NOT safety glasses. Following this rule wellreduce the risk of eye injury_
[] Protect your lungs. Wear a face or dust mask If the operation is dusty. Following this rule
will reduce the risk of serious personal injury_
[] Protect your hearing. Wear hearing protection during extended periods of operation.
