AIR FILTER INDICATOR
The air filter indicator shows when to clean or
replace the air filter element. Check the indicator
daily. The indicator’s red line will move as the air
filter element fills with dirt. Do not clean or replace
the air filter element until the red line reaches
5 kPa (20 in H
2
O) and the “SERVICE WHEN
RED” window is filled with red. The indicator’s red
line may return to a lower reading on the scale
when the engine shuts off. The red line will return
to a correct reading after the engine runs for a
while.
Reset the air filter indicator by pushing the reset
button on the end of the indicator after cleaning or
replacing the air filter element.
AIR FILTER
The engine air filter housing has a dust cap and a
dry cartridge-type air filter element. Empty the
dust cap daily. The air filter must be replaced
whenever the filter element is damaged or has
been cleaned three times.
Machines with the heavy duty air filter option have
a safety element. It is inside the standard
element. Replace this element, do not clean it,
after the regular element has been damaged or
cleaned three times.
Install the dust cap on the air filter housing with
the arrows pointing up.
Service the air filter element only when the air
filter indicator shows restriction in the air intake
system. Do not remove the air filter element from
the housing unless it is restricting air flow.
To clean the filter element, remove it from the filter
housing. Carefully clean the end cap and the
interior of the housing with a damp cloth. Clean
the housing sealing surfaces.
Using an air hose, direct clean dry air, maximum
205 kPa (30 psi), up and down the pleats on the
inside of the element. Do not rap, tap or pound
dust out of the element.
FOR SAFETY: When servicing machine,
wear eye and ear protection when using
pressurized air or water.
After cleaning the air filter element, inspect it for
damage by placing a bright light inside. The
slightest rupture requires replacement of the
element. Inspect the seals on the ends of the
element, they should be flexible and undamaged.
