MAINTENANCE

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 applied.

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.

Throttle lockout

•Make sure the throttle control is locked at the idle setting when the throttle lockout is released.

•Press the throttle lockout and make sure it returns to its original position when you release it.

•Check that the throttle control and throttle lockout move freely and that the return springs work properly.

•Start the chain saw and apply full throttle. Release the throttle control and check that the chain stops and remains stationary. If the chain rotates when the throttle control is in the idle position you should check the carburettor idle adjustment.
