The Causes of Kickback
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 towaYd the operator_.
2. When the blade is pinched
or bound tightly by the kerf
closing down, the blade stalls
and the motor reaction drives
the uni_,apidly back towards
the operator.
If the blade becomes twisted
misaligned in the cut, the_ .
-_ _teeth at.the back edgeof the
blade can dig into the top
surface .of the wood. This
cause s the blade to climb
_,- out of!he_kerf and jump baok
towards the operator.
