MAINTENANCE

Correctly adjusted carburetor

When the carburetor is correctly adjusted the machine

accelerates without hesitation and the machine 4-cycles a

little at max. speed. It is also important that the chain does not

rotate at idle. If the L-jet is set too lean it may cause starting

difﬁculties and poor acceleration. If the H-jet is set too lean the

machine will have less power, poor acceleration and could

suffer damage to the engine.

Checking, maintaining and servicing

chain saw safety equipment

Chain brake and front hand guard

Checking brake band wear

Brush off any wood dust, resin and dirt from the chain brake

and clutch drum. Dirt and wear can impair operation of the

brake.

Regularly check that the brake band is at least 0.6 mm (0,024

inch) thick at its thinnest point.

Checking the front hand guard

Make sure the front hand guard is not damaged and that there

are no visible defects such as cracks.

Move the front hand guard forwards and back to make sure it

moves freely and that it is securely anchored to the clutch

cover.

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 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.

Note! All servicing and repair work on the machine requires

special training. This is especially true of the machine′s

safety equipment. If your machine fails any of the checks

described below we recommend you to contact our

servicing dealer.
