thoroughly. Let the filter cartridge dry out
completely, then dip it in clean engine oil.
Squeeze out carefully any excess oil.
Replace the cartridge only if visibly worn out.

7.4.3 Spark plug maintenance

For both models of generating sets, use spark
plug models BP6ES, BPR6ES (NGK), W20EP-U,
W20EPR-U (ND) or else spark plugs made by
other manufacturers but compatible with the
above.
Never use spark
temperature degree from those listed above.
•
Take the cap off the spark plug (Fig.36 Ref.2)
and using the special wrench take out the
plug.
•
Perform a visual inspection. Replace in case
of obvious wear or if the insulator is broken or
cracked.
•
Use a steel brush to clean the spark plug, if it
can be used again.
•
Use a thickness gauge to measure the
distance between the electrodes. The right
distance should be between 0.7 and 0.8 mm
(Fig. 37).
• Correct the distance if necessary, bending the
side electrode.
•
Make sure that the spark plug washer is in
good condition and then screw back on by
hand to make sure that it is correctly put back
in place. Finally, tighten to the right torque

tightened firmly. A badly positioned spark
plug may become very hot and damage the
engine.

Voltage adjustment

Adjust the voltage when the engine is hot without
any applied load and the generating set is
running.
Check the voltage of the generating set using a
voltmeter via a 230 V vehicle socket. The voltage
must be between 230 V and 245 V without any
connected user.
If different values are measured, it will be
necessary to set the right values by working on
the engine rpm adjustment screw (Fig.38 Ref.1).
Turn the screw clockwise to increase the engine
rpm and consequently, the voltage.
Turn the screw counter-clockwise to decrease
the engine rpm and consequently, the voltage.
