Air Cleaner Service Indicator-Inspect”.
NOTICE
Never run the engine without an air cleaner element
installed. Never run the engine with a damaged air
cleaner element. Do not use air cleaner elements with
damaged pleats, gaskets or seals. Dirt entering the
engine causes premature wear and damage to engine
components. Air cleaner elements help to prevent air-
borne debris from entering the air inlet.
NOTICE
Never service
the air cleaner element with the engine
running since this will allow dirt to enter the engine.
A wide variet
y of air cleaners may be installed for use
with this engine. Consult the OEM information for the
correct procedure to replace the air cleaner.

Engine Air Cleaner Service
Indicator - Inspect
Some engi
nes may be equipped with a different
service indicator.
Some eng
ines are equipped with a differential gauge
for inlet air pressure. The differential gauge for inlet
air pressure displays the difference in the pressure
that is m
easured before the air cleaner element and
the pressure that is measured after the air cleaner
element. As the air cleaner element becomes dirty,
the pre
ssure differential rises. If your engine is
equipped with a different type of service indicator,
follow the OEM recommendations in order to service
the air
cleaner service indicator.
The service indicator may be mounted on the air
clean
er element or in a remote location.
