4 MAINTENANCE
4.1
ALTERNATOR
The alternator does not require any maintenance. Periodic
inspection and cleaning is recommended, depending on
environmental conditions.
However when the alternator has been idle for a long
period attention to winding condition is recommended.
The
condition
of
windings
measurement of insulation resistance to earth.
The CAPACITOR should be disconnected during this test.
A 500V 'megger' or similar instrument should be used. The
insulation resistance to earth of all windings should be in
excess of 1.0 MOhm. Should the insulation resistance be
less than this value, drying out the generator windings is
essential. Drying out can be carried out by direct warm air
from a fan heater or similar apparatus into the generator
air inlets or outlets.
All bearings are greased for life and not regreasable.

ENGINE
4.2.1
Preliminary instructions
All regular maintenance can be carried out when the
enclosure is open. When oil and dirt has gathered in the
enclosure measures have to be taken to avoid spilling oil
and polluting the environment.
The first service on the engine should be carried out after
50 hours of its life and after a major overhaul. In the first
50 hours the engine should receive special attention:
Long periods of light or no load running in the first 50
hours may lead to cylinder glazing and high oil
consumption.
For the same reason it is of the greatest
importance to use the right oil specification
The first time starting up or after running out of fuel it could
be necessary to prime the fuel system.

Bleeding fuel lines
1
Ensure there is sufficient fuel in the fueltank.
2
Loosen the air bleeding screw (1) 1,5 turns . See Fig
16.
3
Unlock liftpump plunger (2) (See fig 16) by turning it to
the left.
4
Operate the liftpump by hand moving the liftpump
plunger up and down, till fuel flows out free of air
bubbles.
5
Lock liftpump plunger (2) (See fig 16) by pushing it full
down and turning it to the right.
6
Tighten the air bleeding screw (1)

4.2.3
Valve clearance
When the engine is in cold condition both valves (inlet and
outlet) should have a clearance between 0.25 mm. The
adjustment has to be done at TDC (refer to § 5.4.2).
