Chain brake
The chain brake is a device which stops the chain in-
stantaneously if the chain saw recoils due to kickback.
Normally, the brake is activated automatically by inertial
force. It can also be activated manually by pushing the
brake lever (left-hand guard) down toward the front.
When the brake operates, a white cone pops up from the
base of the brake lever.
Releasing the Brake
Pull the brake lever up toward the left-hand handle until
it clicks into place.
WARNING
• When the brake operates, release the throttle
lever to slow down the engine speed. Continuous
operation with the brake engaged will generate
heat from the clutch and may cause trouble.
• At machine inspection prior to each job, check
the operating condition of the brake following the
steps below.
1. Start the engine and grasp the handle securely with
both hands.
2. Pulling the throttle lever to maintain the chain op-
eration, push the brake lever (left-hand guard) down
toward the front using the back of your left hand.

release the throttle lever.
