CLEANING AND INSPECTION
WARN I N G
Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and low-toxic
material. However, it may be irritating to the eyes and skin. Use protective gloves and goggles. Use in
well-ventilated areas. Keep away from open flames and other sources of ignition. Failure to do so may
result in injury or death to personnel.
Particles blown by compressed air are hazardous. DO NOT exceed 15 psi (103 kPa) nozzle pressure
when drying parts with compressed air. DO NOT direct compressed air against human skin. Make
sure air stream is directed away from user and other personnel in the area. To prevent injury, user
must wear protective goggles or face shield. Failure to follow this warning may result in injury to per-
sonnel.
CAU T I ON
Observe the following guidelines to clean and inspect the primary filter element:
DO NOT tap or strike the filter element in order to remove dust.
DO NOT wash the filter element.
Use low pressure compressed, filtered, and dry airto remove dust from filter element. Air pressure
must not exceed 30 psi (207 kPa). Direct the air flow along the length of the pleats, never directly at the
filter element, from the inside of the filter element toward the outside. Take care not to damage the
pleats. The primary filter element can be vacuum cleaned for those that require daily service in a dry,
dusty environment. Neither method will remove carbon or oil deposits.
Inspect primary filter element for any signs of deterioration or damage.
The primary air filter element can be used up tosix times if the element is properly cleaned and
inspected. Compressed air can be used on primary elements that have not been cleaned more than two
times. DO NOT use air filters with damaged pleats, gaskets, or seals. Dirt entering the engine will cause
damage to engine components. Discard damaged primary filter elements. The primary filter element
should be replaced at least once per year, regardless of the number of cleanings.
1.
Clean all parts (except filter elements) and surfaces with solvent cleaning compound.
2.
Dry parts with compressed air.
3.
Inspect all parts for damage, wear, pitting, cracks, or corrosion and replace if necessary.
