8) CLEANING OF AIR CLEANER
(1) Primary element
Open the cover and remove the element.

housing body.
Do not clean the filter element by striking or
hitting the filter against any object to shake the
debris from the filter element.
Clean the filter element with compressed air.

b.
Use 3 kg/cm (40 psi) maximum air pressure
and hold the compressed air nozzle at least
2.5 cm (1") away from the pleats while clean-
ing. Make sure to keep the clean side of air
filter free of debris.
Visually inspect for damage to the filter ele-
ments and components. Use a light source to
help identify any defects in the media. If any
defects are observed discard the filter element
and replace with a new primary filter element.
a.
Before any type of cleaning, a visual inspec-
tion of the filter is needed. If there is any dam-
age to the filter body, gaskets or endplates, do
not clean or reuse; the filter should be discard-
ed. Always clean filters in a clean environment,
observe strict inspection procedures and
repackage filters immediately after the clean-
ing process with appropriate materials.
b.
Use observe proper safety precautions and
dispose of waste materials in an environmen-
tally compliant manner.
Re-install filter element into the air housing.
Replace the primary element at the fourth
cleaning.
(2) Safety element
The safety filter element should never be
cleaned since the safety filter is the last barri-
er to contaminant before it reaches engine.
The useful life of the safety filter is equivalent
to that of the primary air filter only if the pri-
mary filter element is being regularly cleaned.
If the primary filter element is not cleaned, the
safety filter should be changed at every third
primary air filter change or after one year of
continuous service, whichever occurs first.
