Section 8
Chain Brake
INERTIAL CHAIN BRAKE
The inertial chain brake ensures maximum safety when using the chain saw. It protects the operator from dangerous kickback which can occur during working phases.
The chain brake can be actuated in two ways. First, when the operator presses the lever (Fig. 25) (manual operation) the chain consequently and instantly locks.
The chain brake is also actuated automatically. This occurs by inertia, when the protective brake is pushed forward (Fig. 26) due to sudden kickback (inertial operation).
The chain brake is released by pulling the lever towards the operator (Fig. 27).
CHECKING BRAKE OPERATION
When you inspect the machine before each job, check the operating condition of the brake following the steps:
1.Start the engine and grasp the handle securely with both hands.
2.Pull the throttle lever to maintain the chain operation, push the brake lever down toward the front using the back of your left hand (Fig. 25).
3.When the brake operates and the chain is stopped, release the throttle lever.
4.Release the brake (Fig. 27).
BRAKE MAINTENANCE
Always keep the chain brake mechanism clean and lubricate the lever with a small amount of oil (Fig. 28). Check wear on the brake band often. Its minimum thickness must be 0.60 mm (0.02”).
