causes and operator Prevention of

kickback:
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 mis-
•
aligned 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 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
a.
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 inter-
b.
rupting a cut for any reason, release
the trigger and hold the saw motion-
less 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 cor-
rective actions to eliminate the cause of
blade binding.
when restarting a saw in the work-
c.
piece, center the saw blade in the cut
and check that saw teeth are not en-
gaged 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
d.
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.
e.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and kickback.
blade depth and bevel adjusting lock-
f.
ing 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
g.
″plunge cut″ into existing walls or
other blind areas. The protruding blade
may cut objects that can cause kickback.
check Lower guard (a7) on circular
10.
saw 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.
check the operation of the Lower

guard (a7) spring on the circular
saw. if the guard and the spring are
not operating properly, they must
