Recommendations For Use - VM Motori D703E2 Manual De Instrucciones

RECOMMENDATIONS FOR USE

During the running-in period (first 50
hours of operation), the engine must be
used with an absorbed load of between
50% and 70% of maximum power.
– Avoid using the engine at the highest
speed for prolonged periods during run-
ningin.
– During the running-in period, do not run
the engine with an absorbed load of less
than 50% or at low idle speed for long
periods. This type of run-in may be the
result of excessive oil consumption and/or
leakage from the exhaust.
– Component service life will be extended
and maintenance costs reduced even if
the engine is run-in for a period longer
than 50 hours with an absorbed load
of between 50% and 70% of maximum
power.
– The engine may function in ambient
temperatures of between -10°C and 45°C.
– When using the engine in ambient tem-
peratures of less than -10° it is possible
to use a preheating system equipped
with a control unit and glow plugs, or a
24V electrical system equipped with a
heater for the fuel filter. This equipment is
optional.
The engine is delivered by the factory
in the running order. However, during
operation the following indications should
be observed:
– During running-in (first 50 working
hours) and throughout the engine lifetime,
carry out the maintenance in compliance
with the intervals established by the ma-
nufacturer (See "Engine maintenance").

If the engine is not regularly used, it
is advisable to start and take it to the
working temperature (70÷80°C) at least
once a month.
If the engine is installed for use in
emergencies, for example in the case
of generators, it must be started at
least once per month.
– Avoid using the engine for long periods
at constant speeds when running in.
– 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
"Technical data" - "Lubrication circuit").
– Properly pre-heat the engine when
using it at low temperatures.
When using the engine at low temperatu-
res (lower than -10°C), fill it with winter-
type fuel.
– Use oils and lubricants with suitable
features (viscosity grade, specifications
and operating temperature) (See "Recom-
mended lubricants").
Only use coolants that comply with the
manufacturer's specifications.
As for the liquid quantity and type, see
"Technical data".
