SAFETY
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.
For your own safety, do not remove the chain brake system.
The installation of a chain brake may be mandatory by law or as stipulated
by insurance regulations in your area of operation. You should inquire
through local government offices, your employer or your local dealer to
ensure that your chainsaw conforms to the required safety standard.
Chain brakes have been designed and tested to comply with international
safety standards as follows:
USA: ANSI Standard B175.1 Safety Requirement for chainsaws
Canada: CSA Standard Z62.1, Z62.3
