• 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's while the chain brake is locked.
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 chain saw 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 chain saws
ANSI Standard B175.1 stipulates that the brake shall stop the chain 0.12 seconds at an engine speed
of 13,500 r/min. It is the responsibility of the owner/operator to ensure that the brake is serviced,
adjusted and tested strictly in accordance with the instructions as detailed here in order to ensure
that the brake performance is maintained in compliance with the Standard B175.1.
Automatic Chain Brake
Kickback produced from the tip of the guide bar will trip the
automatic chain brake. To make sure that the automatic chain
brake operates properly, follow these steps:
1. Stop the engine.
2. Hold the saw with the guide bar approximately 35 cm (14
in.) above a wooden surface. Right hand should hold the
rear handle, and left hand should hold the front handle.
3. Release the front handle and drop the end of the guide bar
against the wooden surface.
4. The impact should lock the chain brake.
When checking the operation of the automatic chain brake, use
a soft surface substance like wood to absorb the impact so the
chain is not damaged.
Other Safety Precautions
1. Do not operate a chain saw with one hand! Serious injury to the operator, helpers, bystanders, or any
combination of these persons may result from one-handed operation. A chain saw is intended for
two-handed use.
2. Do not operate a chain saw when you are fatigued.
3. Use safety footwear, snug-fitting clothing and protective gloves. Wear eye, hearing, and head protection
devices.
