Understanding
Kickback
Preventing Kickback
Kickback is a sudden and unexpected
expulsion of the saw from the workpiece,
which can violently propel the saw back
toward the operator, resulting in accidental
blade contact or impact injury.
Kickback is caused when the saw blade
becomes misaligned, pinched, bound, or
comes in contact with a material it is
unable to cut. When kickback occurs, the
saw blade becomes immediately immo-
bile. The force produced by the motor is
diverted from the blade and transferred
to the saw, pushing it up and away from
the workpiece and potentially toward the
operator.
The lack of warning and high risk of injury
from kickback makes it extremely impor-
tant to: (1) reduce the risk of kickback, and
(2) protect yourself in case it does occur.
Take these precautions to help prevent
the most common causes of kickback:
• Hold saw firmly with both hands and
position arms to help resist kickback
forces. Always stand to one side of saw
when operating—never directly behind
it. When kickback does occur, it will
eject the saw back toward the operator.
• Support large panels, making sure sup-
ports are positioned under both sides of
the cutting line.
• Allow blade to reach full speed before
starting the cut.
• To help prevent the blade from bind-
ing in the workpiece: (1) keep cuts
straight, (2) maintain a consistent depth
and angle throughout cut, (3) provide
proper workpiece support on both sides
of the cut.
• Follow cuts through to completion
whenever possible. If a cut must be
stopped before completion or the
blade begins to bind, release the ON/
OFF trigger and hold the saw motion-
less while the blade comes to a com-
plete stop before removing it from
the workpiece. When resuming the
cut, center your blade in the kerf and
ensure that the teeth are not touching
the workpiece.
• Only use sharp, clean, undamaged
blades. Dull blades create much more
friction and resistance while cutting,
which greatly increases the risk of kick-
back.
