8.4 Saw Chain Brake.
8.4.1 This machine is equipped with an automatic chain brake to stop saw chain rotation in
the event of kickback whilst the chainsaw is in operation.
The brake is automatically operated by inertial force which acts on a weight inside
the front guard.
This brake can also be operated manually with the front guard pushed forward
towards the saw chain.
