To service the air cleaners on all units proceed as fol-
lows:
1.
Loosen outer wing nut and remove with cover.
Remove Element.
2.
Inspect air cleaner housing for any condition
that might cause a leak and correct as
necessary.
3.
Wipe inside of air cleaner housing with a clean,
damp cloth to remove any dirt accumulation,
especially in the area where the element seals
against the housing.
4.
Inspect element by placing a bright light inside
and rotating slowly. If any holes or tears are
found in the paper, discard this element. If no
ruptures are found, the element can be
cleaned.
5.
If a new air filter element is to be used check it
closely for shipping damage.
6.
Install cleaned or new elements in the reverse
order to the above. Tighten wing nut firmly.
7.
Inspect to ensure that the end cap seals tightly
360 degrees around the air cleaner body.
In the event that the filter element must be reused
immediately, compressed air cleaning (as follows) is
recommended since the element must be thoroughly
dry. Direct compressed air through the element in the
direction opposite to the normal air flow through the
element.
Move the nozzle up and down while rotating the
element. Be sure to keep the nozzle at least one inch
(25.4 mm) from the pleated paper.
NOTE: To prevent damage to the element, never
exceed a maximum air pressure of 100 psi (700
kPa).
In the event the element is contaminated with dry dirt,
oil or greasy dirt deposits, and a new element is not
available, cleaning can be accomplished by washing,
using the air cleaner element manufacturer’s recom-
mendations.
NOTE: It is recommended that replacement ele-
ments be installed in the unit. The elements just
removed for cleaning can be washed and stored
as future replacement elements.
In addition, the air cleaner system (housing and
piping) should be inspected every month for any
leakage paths or inlet obstructions. Make sure the air
cleaner mounting bolts and clamps are tight. Check
the air cleaner housing for dents or damage which
could lead to a leak. Inspect the air transfer tubing from
the air cleaner to the compressor and the engine for
leaks.
Make sure that all clamps and flange joints are tight.
GAUGES
The instruments or gauges are essential for safety,
maximum productivity and long service life of the
machine. Inspect the gauges and test any diagnostic
lamps prior to start--up. During operation observe the
gauges and any lamps for proper functioning. Refer to
Operating Controls, for the normal readings.
