- Check calibration of the injectors (consult Service Centre).
The engine runs irregularly
- Check the fuel filters (replace).
- Bleed the air bubbles from the fuel circuit (see par. 5.2).
The alternator voltage is too low
- Check the engine rpm:
1560 rpm without utilities connected at 50Hz
- Excitation capacitors damaged (replace).
Starter battery flat
- Check the electrolyte level in the battery (restore the
level).
- Check functioning of the DC alternator.
- Check integrity of the battery.
The generator does not deliver power
- Check that the magnetothermal switch [Fig. 4, Ref. 2] is
in the ON position. If not, contact an authorised Service
Centre.
8 TRANSPORT AND HANDLING
For transport, all the generators are fixed to a pallet by
means of screws.
For handling on the boat use the engine lifting hooks
located under the top access door [Fig.3, Ref.2]. Hook the
generator carefully and lift it slowly without sudden
movements.
- Hooking the generator at points different from that
indicated may cause damage to the generator or be
dangerous to the operators.
- During lifting all personnel must keep a safe distance
and the operators must wear protective helmets.
9 SCRAPPING
At the end of its lifetime the generator must be taken to
official scrapyards.
Do not dispose of the generator at
household refuse disposal sites, as many of its parts are
polluting.
