THE
FUEL
SYSTEM
The fuel system is developed to eliminate air bubbles
penetrated inside the system,automatically. For
automatic bleeding, activate the fuel pump for few
minutes before starting the engine. To activate the fuel
pump turn on the engine module and then press and
keep pressed START (ref.3) until “pre-heating glow
plug” icon disappear from display.
If there are air bubbles in the fuel system, the engine will
not function regularly or will be unable to reach the rated
rpm. Air may penetrate the fuel circuit through a not
perfectly sealed joint (pipe, filters, tank) or when the fuel
in the tank is at minimum level.

AIR
FILTER
The
IS
series generators are fitted with a dry air filter
(
ref.4
), which prevents foreign bodies from entering
the combustion chamber. It is sufficient to clean the filter
mass with diesel fuel once a year to remove any
impurities.
Take the liquids used to wash the filter
to special waste collection centres for disposal.
