RECOMMENDATIONS FOR USE
The engine is delivered by the factory in the running
order. However, during operation the following indications
should be observed:
1 -During running-in (first 50 working hours) and throu-
ghout the engine lifetime, carry out the maintenance in
compliance with the intervals established by the manufac-
turer (see "Engine maintenance"
2 -If the engine is not used regularly, start it after each
month of inactivity and run it at minimum speed until the
operating temperature (70÷80°C) is reached.
3 -Avoid using the engine at the highest speed for prolon-
ged periods during running- in.
4 -When starting the engine for the first time, run it at
no-load for a few minutes and make sure that the oil
pressure value matches the one stated in the table (see
"Specifications" - "Lubrication circuit").
OPERATING THE ENGINE UNDER SPECIFIC CONDITIONS
The engine performance is affected by fuel temperature,
the temperature and relative humidity of incoming air and
altitude.
When using the engine at high altitudes and high air and
fuel temperatures, the output is reduced.
For further information contact a VM MOTORI STELLAN-
TIS EUROPE assistance centre.

5 -Properly pre-heat the engine when using it at low tem-
peratures. When using the engine at low temperatures
(lower than -10°C), fill it with winter-type fuel.
6 -Use oils and lubricants with suitable features (viscosity
grade, specifications and operating temperature) (see
"Recommended lubricants").
7 -If the alarm signal, which can be acoustic and/or visible
on the control panel according to the type of installation,
is triggered while the engine is running, the electronic
management system may switch the engine to emergen-
cy operation, with automatic restriction of performance
levels..
Important
If the alarm signal is triggered, contact a service
centre.
