Caution! :
Stop the generating set and the cut the
battery supply before working on the electrical circuit.
Alternator belt
Make this check after running the generating set when
the belt is hot.
I
Caution! :
Some parts of the generating set can be
extremely hot.
Check the belt tension by pushing down at midpoint be-
tween the drive pulley and the alternator pulley.
If the belt is too slack, untighten the alternator fixing
bolts
A
and move the alternator to adjust the belt ten-
sion.
Visually check the belt: Check that it is not overly worn
and that the belt strip is not frayed. Replace it if even the
most minor defect is noted.
Check the electrolyte level
The generating set starter battery must remain clean
and dry. Oxidation or the deposit of impurities on the
battery and on its terminals may lead to short circuits,
voltage drops and premature discharging, notably in
wet weather.
The battery terminals and the cables must be cleaned
with a brass brush in order to remove any oxidation.
Tighten the cable terminals and lubricate them with ap-
propriate grease.
If the battery is replaced, use a battery with similar
specifications to the previous one.
If starting with an emergency battery and connection
cables, proceed as follows:
- Connect the emergency battery to the main battery
by connecting the + to the + and the – to the -. When
the engine has started, remove the connection cables.
You should disconnect the 2 battery cables when:
- You use a battery charger
- Before carrying out any work on the electrical equip-
ment
- Before carrying out any welding work

Generating set storage procedure
A set of operations will protect the engine during long
periods of non-use. For prolonged storage before or af-
ter the commissioning, a specific set of measures must
be performed. Contact your Nanni Diesel dealer.
Refer to the Silverwake warranty booklet for more infor-
mations about these operations.
We recommend that you have all these operations
carried out by a Nanni Diesel authorised workshop.
If the engine is likely to be subjected to freezing tem-
peratures, the coolant must be drained.
Restarting the generating set
After operations of winterization, a list of opration lust be
performed before restarting the generating set. Contact
your Nanni Diesel dealer.
