 – English

To maintain as low an
operating temperature as
possible the engine is
equipped with a cooling
system.

The cooling system consits
of:

1. An air intake on the

starter unit.

2. Fins on the flywheel.

Below follows some general maintenance instructions.

If you need further information please contact your service
workshop.

1. Clean the outside of the

machine.

2. Check that the harness is

undamaged.

3. Make sure the throttle

trigger lock and the
throttle function correctly
from a safety point of
view.

4. Check that the stop

switch functions.

5. Check that the chain does

not move at idling speed.

6. Clean the air filter.

Replace if necessary.

7. Check hoses and hose

connections for damage
and wear.

8. Check the cutting

equipment regarding
damage, wear and oil
leakage.

9. Check that all nuts and

screws are tightened.

3. Cooling fins on the cylinder.

4. Cylinder cover (leads cold air onto the cylinder).
Clean the cooling system using a brush at least once a week,
in difficult conditions more often.

Loosen the locking nut for a more manoeuvrable ball joint.

The fixture for the cutting
tool is provided with a ball
joint so that it is easy to
change the cutting angle
during work.

It is important the joint
round the ball joint is
correctly adjusted.

Tighten the locking nut for a
more rigid ball joint.

Clean the shaft every time it
is used.

Dirt which penetrates into
cracks in the shaft can
conduct electricity and result
in personal injury in the
event of contact with an
electric cable.
