It is a good habit to execute, before engine start, a series of simple checks that might represent a valid warranty to avoid
inconveniences, even serious, during engine running. Such checks are usually up to the operators and to the vehicle’s drivers.
- Level controls and checks of any eventual leakage from the fuel, cooling and lubricating circuits.
- Notify the maintenance if any inconvenience is detected of if any filling is necessary.
After engine start and while engine is running, proceed with the following checks and controls:
- check presence of any eventual leakage from the fuel, cooling and lubricating circuits.
- Verify absence of noise or unusual rattle during engine working.
- Verify, using the vehicle devices, the prescribed pressure temperature and other parameters.
- Visual check of fumes (colour of exhaust emissions)
- Checking the coolant level.
Checks not included in maintenance planning-daily checks
MAINTENANCE PROCEDURES
Checks and controls
Engine oil level check.
The check must be executed when the engine is disconnected
and possibly cool.
The check can be made using the specially provided flexible
rod (1).
Draw off the rod from its slot and check that the level is within
the etched tags of minimum and maximum level.
Whether it should be difficult to make the evaluation, proceed
cleaning the rod using a clean cloth with no rag grinding and
put it back in its slot. Draw it off again and check the level.
In case the level results being close to the tag showing
minimum level, provide filling lubrication of the engine’s
components.
To provide filling, operate through the upper top (1) or
through the lateral top (2). During filling operation, the tops
must be removed as well as the rod in order to make the oil
flow easier”.
Refill through upper tappet cover plug. During refill, remove
dipstick for easier oil drain.
The engine oil is highly polluting and harmful.
In case of contact with the skin, rinse well with water
and detergent.
Adequately protect the skin and the eyes, operate
in full compliance with safety regulations.
Disposal must be carried out properly, and in full
compliance with the law and regulations in force.
Check of fuel system
The check must be executed both when the engine
disconnected and when it is running.
The check is made by observing the fuel pipes from the tank
to the fuel pump and to the injectors.
Cooling system check
The check must be executed both when the engine
disconnected and when it is running.
Check the pipes from the engine to the radiator and vice versa;
note any seepage and the state of the pipes especially near the
coupling clamps.
Verify that the radiator is clean, the correct working of the fan
flywheels, the presence of any leakage from the connectors,
from the manifold and from the radiating unit.
Due to the high temperatures achieved by the
system, do not operate immediately after the engine’s
disconnection, but wait for the time deemed
necessary for the cooling.
Protect the eyes and the skin from any eventual high
pressure jet of cooling liquid.
The density of the cooling liquid must be checked any how
every year before winter season and be replaced in any case
every two year.
In case of new filling, proceed bleeding system,
through the bleeds on the engine.
If bleeding of the system is not carried out, serious
inconvenience might be caused to the engine due
to the presence of air pockets in the engine’s head.
NOTE
Lubricating system check
The check must be executed both when the engine
disconnected and when it is running.
Verify the presence of any oil leakage or blow-by from the
head, from the engine pan of from the heat exchanger.
The engine oil is highly polluting and harmful.
In case of contact with the skin, rinse well with water
and detergent.
Adequately protect the skin and the eyes, operate in
full compliance with safety regulations.
Disposal must be carried out properly, and in full
compliance with the law and regulations in force.
