Chain brake

Chain brake

This machine is equipped with an automatic brake to stop saw chain rotation upon occurrence of kickback while in saw cutting operation. The brake is automatically operated by inertial force which acts on the weight fitted inside the front gurd.

This brake can also be operated manually with the front guard turned down to the guide bar.

To release brake, pull up the front guard toward the front handle till “click” sound is heard.

[Caution]

Be sure to confirm brake operation on the daily inspection.

How to confirm:

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.

In case the brake is not effective, ask our dealer inspection and repairing.

The engine, if being kept rotated at high speed with the brake engaged, heats the clutch, causing a trouble. When the brake is operated while in operation, immediately release your fingers from the throttle lever and stop the engine.

Stopping engine

1.Release the throttle lever to allow the engine idling for a few minutes.

2.Move the switch lever downward.
