Break-In Procedure - Vittorazi Motors COSMOS 300 User Manual

4.5 Break-in procedure

A carefully executed break-in phase, following the next instructions, improves the life of the
engine and its performance. The presence of experienced personnel during the running-in phase
is recommended, also to carry out the necessary checks at the end of the period.
The engine must be used carefully in the first hours of break-in (15 litres) and fuel mixture must
be prepared as indicated in the table. The first time the engine is started, it must be warmed up
on the ground for a few minutes, paying utmost attention to noises or abnormal behaviour. We
recommend to complete the break-in on the same day.
