For detailed operations, see pA-4 and pA-5.
DANGER: To avoid physical injury, stop the
engine, allow it to cool, and open the breaker prior to
any intervention.
Observe the rules relative to safety and protection of the
environment.
-These
recommendations
are
mandatory.
Complying with these recommendations will extend the
service life of your engine and will ensure normal
application of the warranty provided with your engine.
-Do not make any unauthorized changes to your
engine.
-Damages produced by use of unauthorized spare parts
are not covered by the warranty.
-Servicing interventions and operations must be
performed in a workshop approved by NANNI
DIESEL.
If the engine is used for a number of hours which is less
than the number of hours indicated, servicing should be
performed on a yearly basis.
In this case, we recommend that the servicing operations
be performed prior to wintering. The engine will thus be
protected by a new and clean lubrication oil. This does
not dispense with the requirement to perform the
wintering operations detailed in the SILVERWAKE
warranty.

Fuel prefilter: draining of water
Absolute cleanliness is required when working on
the fuel circuit since the injection pump and the
injectors have very low tolerances. Even minute
particles of dust or dirt, or very small quantities of
water, can interfere with operation of the fuel
supply.
Perform this operation with the engine cold and
stopped.
The fuel prefilter is an optional equipment
Check that the fuel prefilter does not contain any water.
If it contains water, place a tray under the fuel prefilter.
Drain the water and impurities using the plug/valve at
the bottom of the filter bowl.
Purge the fuel circuit.
This should also be performed when the fuel circuit has
dried or when a portion has been drained.
Loosen the purge screw on the fuel filter bracket.
Actuate the priming pump
13
(
if equipped). Unlock the
hand pump
12
and press the button repeatedly until
bubble-free fuel flows out at the purge screw. Tighten
the purge screw and lock the hand pump.
Oil level (engine, transmission and
power steering).
See page A-4.
The oil checks must always be performed with the
engine stopped and cold. Be careful, these fluids are
flammable. Do not smoke in the vicinity of these fluids
and do not allow for any sparks or flame in the
vicinity.
Engine casing oil: remove the gauge
26
, wipe off the
gauge and reinstall it in the gauge tube.
Pull out the gauge again and check the oil level. It
should be located between the min. and max. positions
on the gauge. If necessary, top up the oil level: open the
air filler port
24
, pour the recommended oil (see
technical characteristics in appendices) to reach the
max. level indicated on the gauge without exceeding the
max. level. Close the oil filler port.
Transmission oil: refer to the documentation relative to
the transmission for this check.
Power steering
(Z transmission only): This check must
be performed with the engine stopped and cold, and
with the base in the horizontal position. Open the
hydraulic oil tank and check the oil level using the
gauge. It should be located between the min. and max.
indicators. If this is not the case, top up with the
recommended fluid (see technical characteristics in
appendices).
If the oil is not visible in the tank, contact your
NANNI INDUSTRIES-
approved dealer
.
