Chain Catcher - Husqvarna 439 Bedienungsanweisung

Checking the inertia brake release
• Place the chain saw, with the engine switched off, on
a stump or other stable surface. Release the front
handle and let the saw fall by its own weight, rotating
around the rear handle towards the stump.
When the bar hits the stump the brake should be
activated.
Checking the brake trigger
• Place the chain saw on firm ground and start it. Make
sure the chain does not touch the ground or any other
object. See the instructions under the heading Start
and stop.
• Grasp the chain saw 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.
