5.5 Air filter cleaning/replacement
For proper functioning and a long life of the engine it is important to periodically clean and replace the air filter. An
inefficient filter may cause loss of engine power and excessive smoke at the exhaust.
To clean or replace the air filter, carry out the following operations.
• Remove the filter holder cover (Fig.
1
, Ref.
F
), undoing the butterfly retaining nut.
• Extract the filter complete with the two elements: the sponge element and the paper element
• The sponge element is simply washed with a domestic detergent or with a low-flammable solvent.
• Leave to dry well and soak the clean element in engine oil, then wring it out to remove the excess oil, since too
much oil in the element causes excessive smoke at the exhaust.
• The paper element is cleaned with a blast of dry air, from the inside to the outside, with a pressure not exceeding
2 bar
. Should it be very dirty or have holes, replace it.
Clean the air filter every 50 hours of operation. Reduce the intervals if the generator operates in particularly
dusty environments.
On average replace the complete air filter every three cleaning operations.
Never clean the air filter with highly-flammable petrol or solvents. This may cause fire or explosions.
Never turn on the engine without the air filter, since this would cause serious damage to the engine.
5.6 Period of inactivity
If the generator is not to be used for a long period of time, the following operations must be carried out.
• Remove the spark plug, pour
3
-
5 cm
3
of oil in the spark plug hole on the cylinder head and make a few starting
attempts without running the generator, in such a way that the engine turns a few times so that the oil can spread
and lubricate the cylinder and the piston; this prevents the formation of rust on the cylinder and the valve. When
the operation has been completed, remount the spark plug.
• Completely empty out the fuel tank.
• Change the engine oil.
• Clean the air filter.
• Clean the outside of the generator, removing all dust and impurities.
• Cover the generator with a nylon sheet and store it in horizontal position in a dry and ventilated place.
