MAINTENANCE
Cooling system
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.
Maintenance schedule
Below follows some general maintenance instructions.
If you need further information please contact your service
workshop.
Daily maintenance
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.
A dirty or blocked cooling system leads to engine
overheating resulting in damage to the cylinder and
piston.
Loosen the locking nut for a more manoeuvrable ball joint.
WARNING!
The engine must not be running during
adjustment.
Adjustment of the 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.
Cleaning of the
shaft
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.
