Kickback may occur when the moving chain at the nose
or tip of the guide bar touches an object, or when the wood closes
in and pinches the saw chain in the cut. Tip or bar nose contact
can, in some cases, cause a lightning-fast reverse reaction, kicking
the guide bar up and back toward the operator. Pinching the cutting
chain along the top of the guide bar may push the guide bar rapidly
toward the operator. Either of these reactions may cause you to
lose control of the saw, which could result in serious personal
injury to yourself or to bystanders.
The top of the tip of the chainsaw guide bar is known
as the KICKBACK DANGER ZONE. When contact is made with an object
such as a branch or a log, there is a danger of a sudden bar nose
kickback reaction.
Modern chainsaws are equipped with a
variety of devices intended to reduce the risk of injury from kickback
or from other causes. Among these are the chain brake, the front
(left) hand guard, the bar tip guard and low or reduced kickback
saw chain and guide bars. To assure the protection afforded by these
devices is maintained, it is important your chainsaw is properly
and fully assembled, and that all components are securely attached
and functional.
No matter how your saw is equipped, Oregon Cutting
Systems recommends that low-kickback chain be used on all saws unless
you have experience and special training for dealing with kickback.
Ask your chainsaw dealer for OREGONŽ low-kickback chain meeting
ANSI requirements of standard B175.1.
Before using any chainsaw, thoroughly
read the manufacturer's operating and safety instructions.
