(c)
Place light inside of filter element and check for ruptured material. Inspect
from outside.
(d)
If inspection reveals any defects, replace filter element.
(e)
If filter is contaminated with dust, clean with compressed air or by washing
(para. (2)(b) below).
(f)
If filter is contaminated with carbon, or oil deposits, replace filter element.
(g)
If filter element in the right air cleaner is contaminated with fuel:
1.
Replace filter element.
2.
Check for proper installation of fuel tank vent valve (para. 3-5).
(2) Cleaning
(a) Compressed air cleaning (Fig. 6-13).
CAUTION
When shaking filter element, keep dust from inside pockets
of element.
Ensure that all creases and seams are free of
dust, and never hit element against any surface.
1.
Grasp filter element at sealing end and shake vigorously to shake out
excessive dust.
2.
Compressed air used for cleaning purposes must not exceed 90 psi. Use
only with effective chip guarding and personal protective equipment
(goggles/shield, gloves, etc.).
3.
Using V-pack cleaner (12326132) (view A), direct stream of compressed
air against inside of filter element (view B).
4.
Move air stream up and down inside length of pleats or pocket until no
dust invisibly being blown out.
5.
Inspect element before installing.
(b) Washing
Do not hit the element
occur to the element.

against a solid
object. Damage may
dust before wetting filter element.
Filter can be immersed in a solution-of warm water (80°F to 110°F) and
detergent (item 6, appendix C).
Soak filter element in cleaning solution for 15 to 20 minutes, then gently
agitate it back and forth for 2 to 3 minutes to free dust deposits.
If a hose is used to wash or rinse filter element, care must be taken not
to rupture filter material with water jet. A maximum line pressure of 40
psi is recommended with cool water (35°F to 80°F). Rinse from inside to
outside.
Rinse dust filter element until all traces of dust and detergent are
removed. Thorough rinsing is very important to service life of dust filter
element.
Thoroughly dry dust filter element before further use. If circulating air
is used; temperature must not exceed 160°F. If circulating air is not
used,
air dry for approximately 6 hours at 70° to 90° ambient
temperature.
(3)
Emergency cleaning. If necessary to clean filter element and neither compressor
not washing facilities are available, filter can be partially cleaned by gently tap-
ping it with the palm of hand.
Care must be taken to avoid damage to filter
element.
Banging, hitting, or tapping my cause deformation and permanent
damage to filter element.
