Cyclonic Dry Air Cleaner
The cyclonic dry air cleaner is a dry element air
cleaner used on units manufactured after
11/15/02. It filters all of the air entering the
engine. Replace the dry air cleaner element when
the air restriction indicator reads 25 in. of vacuum,
or at 2 years, whichever comes first.
NOTE: The dust ejector must point down when
installed.
Air Restriction Indicator
An air restriction indicator is installed in the air
intake manifold on units with a dry air cleaner.
Excessive restriction of the air intake system
reduces the flow of air to the engine. This affects
horsepower output, fuel consumption and engine
life.
Periodically inspect the restriction indicator to
assure the air filter is not restricted. Service the air
filter when the yellow diaphragm indicates 25 in.
of vacuum. Press the reset button on the bottom of
the restriction indicator after servicing the air
filter.
