DISASSEMBLY. (Illus. 4-23).
It is recommended that the body and fixed element in the heavy-duty type air cleaner be serviced every 500 hours of
operation or as conditions justify.
The frequency of servicing may be varied to suit local dust conditions.

CLEANING.
Washing in water-detergent solution and blowing out with compressed air are two accepted methods for cleaning the
main elements of the air cleaner. If elements contain substantial amounts of soot or oil fumes, washing in water works
better than compressed air. If the contaminant is found to be mostly loose dust, either method works equally well. If
cleaned with compressed air, elements can be put back into service immediately; if cleaned by washing, elements must
be dried before returning them to service.
NOTE
SOME ELEMENTS ARE PARTIALLY COVERED BY A PLASTIC SLEEVE WITH FINS. THE
COVERED PORTION CAN BE CLEANED WITH WATER OR AIR WITHOUT REMOVING THE
SLEEVE. USE A STIFF FIBER (NOT WIRE) BRUSH TO REMOVE OIL AND GREASE DEPOSITS
FROM THE SLEEVE AND FINS. NEVER REMOVE SLEEVE AND FINS FROM THE ELEMENT.
CLEANING WITH COMPRESSED AIR.
1. Direct a jet of clean, dry air from the inside of the filter element, perpendicular to the pleats. Pressure at air nozzle
must not exceed 100 psi.
2. Move the air jet up and down along the pleats, slowly rotating the element, until no more dust is being removed. Be
certain that the element is not ruptured by the nozzle or the air jet.
