Presence of water in the fuel filter
It is advisable to drain the water from the filters before the relevant
warning light comes on.
Do not use the engine if the tank only contains the quantity of fuel kept
as reserve; this condition promotes the formation of condensate and
the intake of sludge or air, causing the engine to stop.
Intake and exhaust circuit inefficiencies
Regularly inspect the cleanliness of the air intake circuit. The
maintenance intervals indicated in this manual change with the
conditions of use.
Maintenance checks must be performed more frequently in
particularly dusty environments with regard to that stated in the
chapter CHECKS AND MAINTENANCE.
Electrical start-up system irregularities
Periodically check the cleanliness and efficiency of the batteries,
particularly during winter, by performing the checks and top-ups as
described in the chapter CHECKS AND MAINTENANCE.
In the event of battery replacement, please observe the characteristics
contained in the section ENGINE TECHNICAL DATA.
Refuelling from drums or jerry cans may contaminate
the diesel, resulting in problems with the fuel supply
system; in these cases it is necessary to carry out
adequate filtration or sedimentation of any impurities
present.
ATTENTION!
The couplings of the fuel circuit under high pressure
must not be loosened under any circumstances
ATTENTION!
Visually check that the exhaust circuit is not obstructed
or damaged to prevent noxious and dangerous fumes.
If the voltmeter indicates a voltage value lower than 11
V (for nominal 12 V systems), or 22 V (for nominal 24
V systems), contact a specialised workshop and have
the efficiency of the batteries and charging system
diagnosed.
