iauses and Operator Prevention of Kickback:
rickback is a sudden reaction to a pinched, bound or misaligned saw blade,
ausing an uncontrolled saw to lift up and
out
of the workpiece toward the
Iperator.
Vhen the blade is pinched or bound tightly by the kerf closing down, the blade
tails and the motor reaction drives the unit rapidly back toward the operator.
f
the blade becomes twisted or misaligned in the cut, the teeth at the back
tdge of the blade can dig into the top surface of the wood causing the blade
D
climb out of the kerf and jump back toward operator.
rickback is the result of tool misuse and/or incorrect operating procedures
Y
conditions and can be avoided by taking proper precautions as given below.
naintain a firm grip with both hands o n the saw and position your body and
r m t o allow you t o resist KICKBACK forces. KICKBACK forces can be
ontrolled by the operator, if proper precautions are taken.
Vhen blade is binding, or when interrupting a cut for any reason, release
he trigger and hold the saw motionless in the material until the blade comes
D
a complete stop. Never attempt t o remove the saw from the work or pull
he saw backward while the blade is in motion or KICKBACK may occur.
ivestigate and take corrective actions to eliminate the cause of blade binding.
Vhen restarting a saw in the workpiece, center the saw blade in th& kerf
nd check that saw teeth are not engaged into the material. If saw blade
;
binding,
it
may walk up or KICKBACK from the workpiece as the saw is
?started.
;upport large panels t o minimize the risk of blade pinching and KICKBACK.
arge panels tend t o sag under their own weight. Supports must be placed
nder the panel on both sides, near the line of cut and near the edge of the
anel as shown in Fig. 1 .
o minimize the risk of blade pinching and kickback. When cutting operation
?quires the resting of the saw on the work piece, the saw shall be rested
n the larger portion and the smaller piece cut off.
