WARNING:
serious injury or death to the operator or
others. To decrease the risk you must know
the causes of kickback and how to prevent
them.
A kickback occurs when the kickback zone of the guide
bar touches an object. A kickback can occur suddenly
and with large force, which throws the product in the
direction of the operator.
Kickback always occurs in the cutting plane of the guide
bar. Usually, the product is thrown against the operator
but can also move in a different direction. It is how you
use the product when the kickback occurs that causes
the direction of the movement.
A smaller bar tip radius decreases the force of the
kickback.
Use a low kickback saw chain to decrease the effects of
kickback. Do not let the kickback zone touch an object.
WARNING:
prevents kickback. Always obey the
instructions.

brake is too sensitive, it can engage during rough
operation.

during a kickback?
No. The chain brake must operate correctly to give
protection. The chain brake must also be engaged
