be protected by carrying out the operations described in
Engine storage (up to 6 months) (Par. 4.13) .
• If the engine is still not in use after the first 6 months, it is
necessary to carry out a further operation to extend the
protection period (more than 6 months) (Par. 4.14) .
• If the engine is not to be used for an extended period, the
protective treatment procedure must be repeated within 24
months of the previous one.
4.13 Engine storage up to 6 months
Before storing the engine check that:
• The environments are not humid or exposed to bad weather.
Cover the engine with a proper protective sheet against
dampness and atmospheric contaminants.

When cleaning the engine, if using a pressure washer
or steam cleaning device, avoid directing the nozzle on
electrical components, cable connections and sealed
rings (oil seals etc).
If cleaning engine with a pressure washer or steam
cleaner, it is important to maintain a minimum distance of
at least 200mm between the surface to be washed and the
nozzle - avoiding absolutely electrical components such
as alternators, starter motors and engine control units
(ECU).
12 - Treat non-painted parts with protective products.
13 - Loosen the alternator belt Par. 4.9 .
If the engine protection is performed according to the
suggestions indicated no corrosion damage should occur.
