4.1 Product preservation

Important
• If the engines are not to be used for 6 months, they must be protected by carrying out the
operations described in Engine storage (up to 6 months)
•
If the engine is still not in use after the first 6 months, it is necessary to carry out a further procedure
to extend the protection period (more than 6 months)
• 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.

4.2 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.

•
Avoid storing the engine in direct contact with the ground.
