TB 9-2300-378-14 (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. 1. 2. 3. 4. 5. 6. Shake or blow off CAUTION 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. 6-40
