■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)
IMPORTANT
Be sure to confirm brake operation during 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
