Important
After a year of engine inactivity, the coolant loses its
properties and must be replaced
After a period of inactivity and before installing and running
the engine, it is necessary to carry out a few measures in
order to ensure that it runs at maximum efficiency.
1 - Remove the protective treatment.
2 - Remove any blockages from the exhaust and intake
ducts.
3 - Use a cloth soaked in degreasing product to remove
the external protective treatment.
4 - Remove the intake manifold.
5 - Inject lubrication oil (no more than 2 cm
3
) into the
valves and replace the intake manifold.
6 - Adjust the alternator-fan belt tension.
7 - Turn the flywheel manually to check the movement of
the mechanical parts.
8 - Start the engine and run at ¾ of the maximum speed
for 5-10 minutes.
9 - Switch off the engine.
10 - Remove the protective oil to replace with engine oil.
11 - Introduce new oil (see “Table of lubricants”) up to the
correct level marked on the dipstick.
12 - Check the filters for aging (air, oil, fuel) and, if
necessary, replace them with original spares.
Important
Over time, a number of engine components and
lubricants lose their properties, even when the engine
is not in use, and so it is important to consider whether
they need replacing, based not only on the number
of hours of use, but also on age and wear.
13 - Install the engine onto the machine and make the
necessary connections and unions.
14 - Make sure that electrical contacts are intact and
efficient.
15 - Check that the engine oil and coolant are up to level.
16 - Start the engine and keep at minimum speed for a few
minutes.
17 - Check for leaks and, if necessary, find and eliminate
the cause.
