INLET FILTER MAINTENANCE
Refer to Figure 6-2. Inlet filter maintenance should
be performed under any of the following conditions,
whichever occurs first.
1. As indicated by the filter maintenance gauges.
2. Every six (6) months.
Following, you will find procedures on how to
replace and clean the air filter element.
INLET FILTER ELEMENT REPLACEMENT
1. Clean exterior of air filter housing.
2. Remove the inlet filter cover by loosening the
wing nuts securing the cover.
3. Remove element and clean the base and interior
of cover using a damp cloth. DO NOT blow dirt
out with compressed air.
4. At this time, clean or replace the element.
5. Replace cover.
INLET FILTER ELEMENT CLEANING
The inlet filter element may be cleaned by com-
pressed air. When cleaning the element with com-
pressed air, never let the air pressure exceed 30 psi
(207kPa). Reverse flush the element by directing
the compressed air up and down the pleats in the
filter media from the "clean side" of the element.
Continue reverse flushing until all dust is removed.
Should any fluid or greasy dirt remain on the filter
surface, the element should then be replaced.
When the element is sufficiently cleaned, inspect it
thoroughly prior to installation (see Element
Inspection).
ELEMENT INSPECTION
1. Place a bright light inside the element to inspect
for damage or leak holes. Concentrated light will
shine through the element and disclose any
faulty areas.
2. Inspect all gaskets and gasket contact surfaces
of the housing. Should faulty gaskets be evident,
correct the condition immediately.
3. If the clean element is to be stored for later use,
it must be stored in a clean container.
4. After the element has been installed, inspect and
tighten all air inlet connections prior to resuming
operation.
