•  When engine starts, keep idling for a few minutes. 
•  Set the brake lever in the unlocked position before 

starting to cut.

•  Pull throttle trigger gradually and increase revolution 

of the engine. 

•  The chain starts running when the engine reaches 

4000 r/min approximately. 

•  Confirm proper acceleration and lubrication of chain 

and bar.

the throttle to half speed for 30 seconds.
