Safety Features
This saw is equipped with certain safety features and devices to protect the user from harm in the event the saw reacts unexpectedly to external forces:
1.Chain Brake: The saw is equipped with a chain brake designed to stop the chain instantaneously upon activation. The chain brake can be activated in one of two ways:
•The forward hand guard doubles as an activation lever for the hand brake. It can be activated manually, or it may be activated by the user’s arm if a kickback occurs.
•The saw is also equipped with an “Inertial Chain Break.” The same mechanism as above is activated by the inertial force created when a counterweight under the forward hand guard accelerates toward the bar nose during a kickback.
•Proper cleaning and care of the chain brake system are required to ensure reliable operation in the field. You should also check your chain brake for proper operation regularly. To check your chain brake:
Manually activate the chain brake by pushing the forward hand guard toward the bar nose. There will be an audible click when the chain brake engages. If there is no audible click, the brake may already be engaged. Pull back on the forward hand guard to deactivate the brake. An audible click should be heard when the brake disengages. If there is still no audible click, the brake is not functioning properly. Remove the clutch cover, clean and reassemble, and
With the saw’s engine shut off and the brake disengaged, firmly grasp both handles and hold the saw over a log or low stump. Swing the bar nose sharply down until it makes contact. This should create enough inertial force to automatically activate the chain brake. When the brake engages, an audible click should be heard. If no audible click is heard, the brake is not functioning properly. Remove the clutch cover, clean and reassemble, and
2.Throttle Interlock: This saw is equipped with a throttle interlock designed to prevent accidental engagement of the throttle control. The throttle interlock is disengaged by depressing the red tab on top of the rear handle. This is usually accomplished when the user grasps the rear handle to operate the saw.
3.Chain Catcher: Each saw is equipped with a chain catcher beneath the clutch cover. If the chain is ever thrown from the guide bar, or if the chain breaks, the chain catcher is designed to capture the chain and prevent it from whipping back toward the operator.
NOTE: Inspect the chain catcher before each use. Replace if missing or badly damaged.
4.Kickback Reduction Guide Bar and Saw Chain: This saw has been equipped with a Double Guard® 91 guide bar and 91VG
