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.
• Thesawisalsoequippedwithan“InertialChainBreak.”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 eld. 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 re-test.
If no audible click is heard, contact customer service for
further assistance.
With the saw’s engine shut o 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 re-test. If no audible
click is heard, contact customer service for further assistance.
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
S-Series Low Kickback saw chain by Oregon®. The features of
this bar and chain combination are design to reduce the risk
of kickback. To maintain adequate kickback prevention, only
use these components when replacing guide bar or saw chain.
