ENGINE PRE-HEATING (optional)
(220 V, single phase electrical device)
The engines for which low temperature start-up and immediate
delivery of power are required may be fitted with a 220 V single
phase electrical heating device, which allows the temperature of the
coolant to be raised to or maintained at suitable values. The device
is fitted with a thermostat to cut the power supply when the
required temperature is reached.
FOR PROPER USE OF THE ENGINE
(with the exception of power generator engines)
Do not leave the key turned to the start position
1C, when the
engine has started.
It is not efficient to leave the engine running at minimum speed
while waiting for it to reach the proper working temperature; it
is preferable that, after approximately one minute from start-up,
you gradually increase the engine load.
Do not leave the engine running at minimum speed for long, as
this increases the production of harmful emissions and does not
guarantee the best performance.
The engine speed must be increased and decreased gradually, to
allow regular combustion and proper operation of all engine
components.
The running speed and power values must comply with the
specifications on the technical and commercial documentation.
During use, periodically check that:
1. The engine coolant temperature does not reach the alarm
threshold.
2. The oil pressure remains within normal values.
If the temperature is considered too high, reduce speed and stop to
check the state of the cooling system circuits; also check and have
checked:
a) the tension of the auxiliary member drive belt;
b) operation of the thermostat valve;
c) whether or not the heat exchanger is clean.
