Position the chainsaw in such a way that
your body is clear of the cutting attach-
ment whenever the engine is running.
Stand to the left of cut while bucking.
powerful force used to cut wood can be
reversed (and work against the opera-
tor). If the rotating chain is suddenly
stopped by contact with any solid object
like a log or branch or is pinched, the
reactive forces may occur instantly.
These reactive forces may result in loss
of control which may, in turn, cause
serious or fatal injury. An understanding
of the causes of these reactive forces
may helpyou avoid loss of control.
Don’t put pressure on the saw when
reaching the end of a cut. The pressure
may cause the bar and rotating chain to
pop out of the cut or kerf, go out of
control and strike the operator or some
other object. If the rotating chain strikes
some other object, a reactive force may
cause the moving chain to strike the
operator.
The reaction of the cutting force of the
chain causes a rotational force on the
chainsaw in the direction opposite to the
chain movement. This may fling the bar
up and back in an uncontrolled arc
mainly in the plane of the bar. Under
some cutting circumstances the bar
moves towards the operator, who may
suffer severe or fatal injury.
The most common reactive forces are
– kickback,
–
–
pushback,
pull-in.
Reactive forces including kickback
!
Kickback:
Warning!
Kickback may occur when
the moving saw chain
Reactives forces may occur any time the
chain is rotating. Reactives forces can
be dangerous! In any chainsaw, the
near the upper quadrant of
the bar nose contacts a
solid object or is pinched.
Kickback may occur when the nose of
the guide bar is pinched unexpectedly,
unintentionally contacts solid material in
the wood or is incorrectly used to begin
a plunge or boring cut.
