•Do not cut above shoulder height. It is difficult to maintain con- trol 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 gasoli- ne powered chain saws as set by ANSI B175.1 - 1991.

•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 kick- back performance requirements when tested on a representa- tive sample of chain saws below 3.8 cubic inch displacement specified in ANSI B175.1 - 1991.

•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.

 

(A)

 

 

 

 

 

 

 

 

 

 

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.
