can result from one-handed operation.

• When bucking, secure the work piece
prior to cutting. When felling or pruning,
identify and secure hazardous branches.
• Aggressive or abusive cutting or misuse
of the chainsaw can cause premature
bar, chain, and/or sprocket wear, as
well as broken chain or bar, leading to
kickback, chain throw or the ejection of
material.
• Never use the guide bar as a lever. A
bent guide bar can cause premature
bar, chain, and/or sprocket wear, as
well as broken chain or bar, leading to
kickback, chain throw or the ejection of
material.
• Use extreme caution when cutting small
brush and saplings because slender
material can catch the saw chain and be
whipped toward you or can cause the
chain to be thrown from the guide bar.
• Cut only one work piece at a time.

cHain Brake

The chainsaw comes equipped with
a chain brake, which stops both the
motor and the motion of the chain
when kickback occurs (Fig. 3). The chain
brake can be activated by the forward
motion of the hand guard as the saw
rotates backward during kickback; it can
also be activated by the inertial forces
generated during rapid pushback.
