BLEEDING
The presence of air bubbles in the fuel system is the
cause of irregular functioning of the engine or the incapacity
to reach the nominal rpm. Air might enter inside the fuel
circuit through a not perfectly tight seal (pipes, filters,
tank) or when the fuel in the tank is at minimum level. To
remove the air bubbles from the fuel circuit, the cause
which has allowed air to enter the circuit must first be
removed.
The generator engine is self-bleeding, therefore, once the
cause of the air intake into the fuel system has been
removed, it automatically expels it.
Nevertheless, the self-bleeding operation may take several
minutes.

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 replace the air filter, carry out the following operations:
- Remove the cover (ref. 1) from the filter holder by acting
on the crooks (ref.2).
- Remove the cartridge (ref.3), clean it, and, if necessary,
replace the filter.
- Remount the cover (ref.1) and fix it with the external
crooks (ref.2) to the filter holder, taking care to fix it with
the breather pipe facing downward (ref.4).
During the cleaning operation, pay attention to the following:
- Never beat the cartridge to remove the dirt, but use dry
compressed air, from the inside to the outside, at a MAX
pressure of 2 bar;
- Light up the inside of the cartridge to check its state and
if there are any splits or holes, replace it.
On average replace the filter cartridge every 3 cleaning
operations.
