Kickback Safety
35703
This saw is equipped with the following
safety equipment:
■ Operator activated and Inertial
type chain brake. In the event of
kickback, kickback energy either
forces the brake lever against the
operator's hand when the saw is
held as illustrated above activating
the chain brake and/or inertia
causes chain brake activation.When
the brake is activated, a spring-
loaded brake band is applied against
the chain drive mechanism, stop-
ping the chain rotation.
WARNING!
To reduce the risk of kickback, all
of the above devices must be
properly installed and in good
repair. Use of other than ANSI
B175.1-2000 bar and chain
combinations may result in
reduced kickback protection!
WARNING!
Kickback can
happen lightning-
fast!
■ "Low kick" chain. When used in
combination with the appropriate
guide bar, low kick chain signifi-
cantly reduces the effects of
kickback.
WARNING!
Brake engagement and
operation depends upon proper
inspection and maintenance
procedures! For correct proce-
dures, see page 21.
WARNING!
Never operate this or any
other chain saw with only one
hand! One-handed operation
could cause serious injury to the
operator, helper, or any nearby
observers! A chain saw is in-
tended for two-handed operation!
