SPECIAL WARNINGS
Coolant circuit
When the engine is running, regularly check that the engine coolant
temperature does not reach the alarm threshold.
In case the temperature detected is excessive, disconnect the load and
stop the engine to check the cooling circuit status.
If the temperature is considered too high, reduce speed and stop to
check the state of the cooling system circuits.
Check the following:
a) the tension of the auxiliary member drive belt;
b) the thermostatic valve’s efficiency;
c) the conditions of the heat exchanger (to be cleaned if necessary).
Lubrication circuit
Regularly check that the oil pressure keeps within normal values. In
case the value detected is too low, check the oil level and refill if
necessary following the instructions reported in the CHECKS AND
MAINTENANCE section.
If the condition persists, contact the Authorised Service Centre.
Fuel circuit
Avoid using the engine with small reserve of fuel in the fuel tank. Thus
the vapour condensation is encouraged and makes the engine more
likely to inhale dirt or air, resulting in engine stoppage.
Air intake and exhaust gas circuits
Inspect the cleanliness of the air intake circuit on a regular basis. The
maintenance intervals indicated in this manual vary according to the
conditions in which the engine is operated.
In particular dusty environments it is necessary to carry out
maintenance within more frequent intervals than indicated in the
CHECKS AND MAINTENANCE section.
CAUTION!
When the engine is hot, pressure builds up in the
cooling circuits which may eject hot liquid violently,
resulting in a risk of burns. Open the filler cap of the
coolant tank only when the engine is cold.
CAUTION!
While refuelling, always pay attention to ensure that no
solid or liquid pollutants enter the fuel tank; remember
that smoking and live flames are prohibited during
refuelling.
CAUTION!
Never loose the high pressure fuel circuit connectors in
any way.
