ANSI Standard B175.1 and CSA
Z62.1.3 stipulate 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 Standards B175.1 and CSA
Z62.1.3
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 inches) 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.
