Chain Brake Operation
The Shindaiwa 357 saw is equipped with an inertial chain brake that stops the saw chain whenever the brake lever is moved to the forward (engaged) position.
■Engaging the brake lever causes a brake band to tighten around the clutch drum, stopping the chain.
■The chain brake is designed to engage whenever the brake lever strikes the operatorÕs hand.
■The chain brake can also be activated by pushing the brake lever forward manually.
■To release (disengage) the chain brake, pull the brake lever toward you.
WARNING!
The chain brake is installed only to reduce
the risk of injury from kickback! The chain brake is not a substitute for careful operation!
IMPORTANT!
Release the throttle whenever the chain brake is activated!
