Fig. 5
Correct Blade Depth Blade is Set Too
Deep
1 Kickback is a sudden reaction to a pinched,
bound or misaligned saw blade, which
causes an uncontrolled saw to lift up and
out of the workpiece and toward
the operator.
2 When the blade is pinched or bound tightly by the
kerr closing down, the blade stalls and the motor
reaction drives the unit rapidly back towards the
operator
3 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 This causes the
blade to climb out of the kerr and
jump back towards the operator
4 Sawing into knots or nails in the workpiece
can cause Kickback
5 Sawing into wet or warped lumber can
cause Kickback, (see Fig. 6a)
6 Forcing a cut, or not supporting the workpiece
correctly can cause Kickback (see Fig 6a)
7 Kickback is a result of tool misuse and!or incorrect
operating procedures or conditions
It can be avoided by taldng the proper
precautions, on page 19,
