Air Cleaner Restriction Indicator
The air cleaner is equipped with a restriction indicator
(Figure 80). As the air cleaner element becomes clogged,
air intake restriction increases and the indicator signal
shows RED, indicating that the element needs to be
replaced. After replacing the air filter element, press the
restriction indicator button to reset the indicator.

the indicator displays RED. Dispose of the old element.
It cannot be cleaned or reused.
FUEL FILTER
DANGER
Fuel spillage on a hot engine can cause
a fire or explosion. If fuel spillage occurs,
wipe up the spilled fuel completely to
prevent fire hazards. NEVER smoke
around or near the generator. ALWAYS
shut down the engine prior to cleaning up any spilled fuel.
Inspect the engine fuel filter daily. If the fuel filter has
collected a significant amount of water and sediment at
the bottom of the cup, it should be drained off immediately.
