such filters may have inadequate or questionable
working pressure ratings.
AIR FILTER MAINTENANCE

be performed when the maintenance gauge shows

(electro---mechanical models only).
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
holes.
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.

be changed when the maintenance gauge shows
