CHAIN BRAKE
This machine is equipped with an automatic brake to
stop saw chain rotation upon occurrence of kickback
during saw cutting. The brake is automatically operated
by inertial force, which acts on the weight fitted inside
the front guard.
This brake can also be operated manually with the
front guard turned down to the guide bar.
To release the brake, pull up the front guard toward the
front handle till a “click” sound is heard. (F15)
[Caution]
Be sure to confirm brake operation during daily
inspection.
How to cofirm:
1) Turn off the engine.
2) Holding the chain saw horizontally, release your
hand from the front handle, hit the tip of the guide
bar to a stump or a piece of wood, and confirm
brake operation. Operating level varies by bar size.
(F16)
In case the brake is not effective, ask our dealer for
inspection and repairs.
If the engine keeps rotating at high speed with the
brake engaged, the clutch will overheat causing
trouble.
When the brake engages during operation,
immediately release the throttle lever to stop the
engine.
