Correct Use Of Chain Brake
Chain Brake Operation
• Set the lever in the unlocked position before starting to cut.
• If the brake is tripped by kickback
reaction, the chain will stop
immediately. Release the throttle
to avoid possible damage to the
engine or clutch.
• Do not attempt to operate the
engine with the brake locked.
Testing The Brake
• Start the engine on a solid level
surface and run at a fast idle until
warm.
• Hold the saw firmly by the
handles and accelerate the
engine to a fast idle.
• Slowly operate the chain brake
lever while holding the saw firmly on the ground. When the brake lever
trips, the chain should stop. Immediately release the throttle trigger.
Do not allow the saw to tip forward in order to avoid damage to the
chain.
If the chain does not stop immediately, return the saw to your
authorized dealer for repair.
Note:
• For practice, while cutting a small tree, push the lever forward to lock
the brake.
• Confirm that the brake works properly before each use.
• If the chain brake is clogged with wood chips, function of the brake may
deteriorate. Always keep the device clean.
• Do not increase engine RPM while the chain brake is locked.
Do not use a bar and chain combination other than those specified in this
manual.
