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, center 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 making a "plunge cut" into existing walls or other
blind areas. The protruding blade may cut objects that can cause kickback.

LOWER GUARD SAFETY INSTRUCTIONS

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" 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 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

• Use clamps or another practical way to secure and support the workpiece to a
stable platform. Holding the work by hand or against your body leaves it unstable and
may lead to loss of control.
• Keep your body positioned to either side of the blade, but not in line with the
saw blade. KICKBACK could cause the saw to jump backwards (see Causes and
Operator Prevention of Kickback and KICKBACK).
• Avoid cutting nails. Inspect for and remove all nails from lumber before cutting.
• Always make sure nothing interferes with the movement of the lower blade guard.
• Accessories must be rated for at least the speed recommended on the tool
warning label. Wheels and other accessories running over rated speed can fly apart
and cause injury. Accessory ratings must always be above tool speed as shown on
tool nameplate.
• Always be sure all components are mounted properly and securely before using tool.
• Always handle the saw blade with care when mounting or removing it.
• Always wait until the motor has reached full speed before starting a cut.
• Always keep handles dry, clean and free of oil and grease. Hold the tool firmly with
both hands when in use.
