SAFETY RULES
• Do not cut above shoulder height. It is difficult to maintain
control of saw above shoulder height.
Kickback Safety Features
WARNING: The following features are included on
your saw to help reduce the hazard of kickback;
however, such features will not totally eliminate this
dangerous reaction. As a chain saw user, do not rely
only on safety devices. You must follow all safety
precautions, instructions, and maintenance in this
manual to help avoid kickback and other forces
which can result in serious injury.
• Reduced-Kickback Guide Bar, designed with a small radius tip
which reduces the size of the kickback danger zone on the bar
tip. A Reduced-Kickback Guide Bar has been demonstrated to
significantly reduce the number and seriousness of kick-backs
when tested in accordance with safety requirements for
gasoline powered chain saws as set by ANSI B175.1- 2000.
• Low-Kickback Chain, designed with a contoured depth gauge
and guard link that deflect kickback force and allow wood to
gradually ride into the cutter. Low-Kickback Chain has met
kickback performance requirements when tested on a
representative sample of chain saws below 3.8 cubic inch
displacement specified in ANSI B175.1 - 2000.
• Front Hand Guard, designed to reduce the chance of your
hand contacting the chain as your hand slips off the front
handlebar.
• Position of front and rear handlebars, designed with distance
between handles and "in-line" with each other. The spread and
"in-line" position of the hands provided by this design work
together to give balance and resistance in controlling the pivot
of the saw back toward the operator if kick-back occurs.
Chain Brake
Chain brakes are designed to rapidly stop the chain from
rotating. When the chain brake lever / hand guard is pushed
toward the bar, the chain should stop immediately. A chain
brake does not prevent kickback.
The chain brake Run Position (A) and Brake Position (B) are
illustrated on Fig. 19.
Chain brake should be cleaned and tested daily. Clean the
chain brake per the Maintenance-Chain Brake Section and test
per the Operation-Chain Brake Operation Section.
WARNING: Even with proper maintenance, the
correct operation at the chain brake under field
conditions can not be certified.
