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 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

Canada: CSA Standard Z62.1, Z62.3 

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.

35 cm

(14 in.)
