combination wrench

A combination wrench tool is provided for use when per- forming various maintenance procedures. On-board storage keeps the tool handy at all times.

front hand guard / CHAIN BRAKE

The chain brake is designed to quickly stop the chain from rotating. When the front hand guard/chain brake is pushed toward the bar, the chain should stop immediately. The chain brake does not prevent kickback.

GUIDE BAR

The factory-equipped guide bar has a small radius tip that offers a somewhat lower kickback potential.

LOW KICKBACK SAW CHAIN

The low kickback saw chain helps minimize the force of a kickback reaction by preventing the cutters from digging in too deeply at the kickback zone.

primER bulb

The primer bulb pumps fuel from the fuel tank to the car­ buretor.

SAFE-T-TIP ANTI-KICKBACK NOSE GUARD

The Safe-T-Tip Anti-Kickback Nose Guard is an attach- ment provided on the end of the guide bar to prevent the chain on the end of the guide bar from contacting the wood.

THROTTLE lock

The throttle lock feature allows you to start the chain saw without having to continuously hold the throttle trigger.

THROTTLE TRIGGER

The throttle trigger is used for starting the chain saw, and also for controlling chain rotation.
