Checking the inertia brake release
• With the engine turned off, hold the chain saw over a
stump or other firm object. Let go of the front handle
so that the bar drops towards the stump as the chain
saw rotates around the rear handle.
When the bar hits the stump the brake should be
activated.
Checking the brake trigger
• Place the chainsaw on firm ground and start it. Make
sure the chain does not touch the ground or any other
object. See instructions under the heading Starting
and stopping.
• Grasp the chainsaw firmly, wrapping your fingers and
thumbs around the handles.
• Apply full throttle and activate the chain brake by tilting
your left wrist forward onto the front hand guard. Do
not let go of the front handle. The chain should stop
immediately.
