7. Operation
• When the brake worked, immediately release
the throttle lever and slow down the engine
speed. Running the engine at high speed while
braking the saw chain can cause clutch failures.
• Before starting the day's job, check the condition
of the brake system as follows:
1) Start the engine and grasp the handles
securely with both hands.
2) While pulling the throttle lever, slowly push
the brake lever (front hand guard) forward
with the back of your left hand.
3) Check that the brake works normally, then
release the throttle lever.
4) Pull the brake lever back to the OFF position.
