MAINTENANCE WHEN THE ENGINE IS LEFT IDLE
If the boat where the engine is installed is left idle for a
GB
long time, it is necessary to carry out some maintenance
work to preserve the engine's maximum efficiency condi-
tions.
If the engine is not used for short periods of time, carry
out the following interventions:
1 -Make sure the electric contacts are working properly
and, if necessary, protect them with an anti-oxidant spray.
2 -Check the charge of the battery and the liquid level.
3 -If necessary, carry out the scheduled maintenance
work (see "Engine maintenance").
MAINTENANCE IN CASE OF ENGINE INACTIVITY
After a period of inactivity, it is necessary to carry out a
few maintenance interventions before starting the engine
again to ensure its maximum efficiency conditions.
– Check the charge of the battery and the liquid level.
– Make sure the electric contacts are intact and properly
working.
– Carry out the operation diagnosis of the engine (see
"Diagnosis of failures").
– Check the oil level, and, if necessary, top up or replace
it according to the established intervals see ("Routine
maintenance table after running-in").
– Replace the oil filter according to the established inter-
vals (see "Routine maintenance table after running-in").
– Check the coolant level, and if necessary, top up or
replace it according to the established intervals (see
"Routine maintenance table after running-in").
– Replace the fuel filter according to the established inter-
vals (see "Routine maintenance table after running-in").
– Replace the air filter according to the established inter-
vals (see "Routine maintenance table after running-in").
CHECKS AND CONTROLS
The information needed to carry out all maintenance,
check and control operations which do not require the
replacement of mechanical components are provided
below.
English
It is advisable to start the engine bringing it to the
operating temperature (70÷80°C) at least once per
month.
The engine must be started once per month if it is
installed for emergency purposes.
If the engine is left idle for prolonged periods, carry
out the engine protective treatment to guarantee its
efficiency for 6 months and to avoid continuous con-
trol and maintenance interventions. If the engine is
not used for a further period of time, check the need
to repeat the protective treatment for other 6 months
(see "Engine Storage").
– Tension again the transmission belt (see "Method for
tightening or loosening the belt").
– Check the tightening of the hydraulic unions (see "Con-
trol screw tightening and union sealing").
– Check the integrity of the impeller of the seawater pump
(see "Routine maintenance table after running-in)".
– Check the integrity of the electrolytic zinc (see "Routine
maintenance table after running-in")
– Use a cloth soaked in a degreasing product to remove
the external protective treatment.
– Start the engine and run it at minimum speed for a few
minutes (see "Engine ignition and turning off").
– If no anomalies are detected, bring the engine to its
operating temperature (70÷80°C).
– Turn off the engine and check again the engine oil and
coolant level.
