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.
•
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.
To minimize the risk of blade pinching and kickback.
When cutting operation requires the resting of the
saw on the workpiece, the saw should be rested on
the larger portion and the smaller piece cut off.
To avoid kickback, do support
board or panel near the cut.

Do not support board or
panel away from the cut.

•
Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive friction,
blade binding and kickback. Keep blade sharp
and clean. Gum and wood pitch hardened on
blades slows saw and increases potential for
kickback. Keep blade clean by first removing it
from tool, then cleaning it with gum and pitch
remover, hot water or kerosene. Never use
gasoline.
•
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 making a "plunge
cut" into existing walls or other blind areas.
The protruding blade may cut objects that can
cause kickback. For plunge cuts, retract lower
guard using retracting handle.
•
ALWAYS hold the tool firmly with both
hands. NEVER place your hand or fingers
behind the saw.
If kickback occurs, the saw
could easily jump backwards over your hand,
leading to serious personal injury.

•
Never force the saw. Forcing the saw can
cause uneven cuts, loss of accuracy, and
possible kickback.
Push the saw forward at
a speed so that the blade cuts without slowing.
