AIR FILTER RESTRICTION INDICATOR
The air filter restriction indicator signals when to
clean or replace the air filter element. Check the
restriction indicator daily. The yellow indicator
gradually becomes visible as the air filter element
loads with dirt.
Do not clean or replace the air filter element until the
yellow indicator reaches the top of the service
indicator and reads 20 in (500 mm). The indicator
may return to the “no restriction” position when the
engine is shut off. It will return to the “visible”
position when the engine is started.
Clean or replace the filter element when the yellow
indicator reads 20 in (500 mm). After cleaning or
replacing the air filter element, reset the service
indicator by pushing the “reset” button on the end of
the indicator.

AIR FILTER
The engine air filter housing includes a dust cap and
two dry cartridge-type air filter elements.
The dust cap must be emptied of dirt daily.
The air filter element must be cleaned and inspected
or replaced whenever the yellow indicator of the air
filter restriction indicator reads 20 in (500 mm). The
filter element must be replaced if it is damaged or
has been cleaned three times.
Inside the air filter element is the air filter safety
element. This element should be replaced, not
cleaned after the regular element has been damaged
or has been serviced three times.
Service the air filter element only when the restriction
indicator indicates excessive restriction in the
system. Do not remove the air filter element unless it
is restricting air flow.
