Be careful to ensure that the fuel in the 
lter does not drain completely out. 
If it does, remove it (see “Fuel lter

throw away any polluting material in 
the environment. Carry out their di-
sposal in compliance with the relevant 
legislation in force.
9 - When an alarm signal (visual and/or 
acoustic) is triggered by the control panel 
this indicates that there is a malfunction of 
some kind.
In the presence of anomalies, the 
electronic engine management system 
activates protective strategies and also 
the limitation of the engine performan-
ces if necessary.
In these conditions it is possible to 
check the ignition of the indicator light 
(MIL) for the engines R750EU5 or of the 
system indicator light (SYS) for the en-
gines R750TE3-IE3, R750TE4-IE4-ISE4.
Do not continue to use the engine with 
the MIL indicator light on, instead con-
tact an authorized VM Motori assistan-
ce centre.
Do not attempt to disconnect the MIL 
indicator light sensor in order to clear 
the signal. VM Motori does not assume 
any liability for economic damages 
or risks to personal safety. For more 
information, refer to the documentation 
provided by the manufacturer of the 
vehicle/device in which the engine is 
installed.
To solve the problem, proceed as indica-
ted.
– Turn off the engine.
–Consult chapter “INFORMATION ABOUT 
FAILURES” for the action to be taken and 
details of how to deal with the causes that 
triggered the state of emergency.
– In case of doubts, never operate 
directly, but contact a VM authorised 
workshop.
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.
