This circular saw should not be mounted to
a table and converted to a table saw.
Circular saws are not designed or intended to
be used as table saws.
This tool is not designed for use with metal
or masonry cut-off wheels.
Do not use abrasive wheels with circular
saws. Abrasive dust may cause lower
guard to fail.
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.
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 tool 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 action 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 blade is binding, it may walk
up or kickback from the workpiece as the saw
is restarted.
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.
Use extra caution when sawing into
existing walls or other blind areas. The
protruding blade may cut objects that can
cause kickback.
The blade washers and the bolt on your
saw have been designed to work as a
clutch to reduce the intensity of a kickback.
Understand the operation and settings of
the VARI-TORQUE CLUTCH.
setting of the clutch, combined with firm
handling of the saw will allow you to control
kickback.
Never place your hand behind the saw
blade. Kickback could cause the saw to jump
backwards over your hand.
Do not use the saw with an excessive
depth of cut setting. Too much blade
exposure increases the likelihood of the blade
twisting in the kerf and increases the surface
area of the blade available for pinching that
leads to kickback.
