CLEANING AND INSPECTION
1.
Check sealing surfaces on filter elements for dirt on the "clean" side. If this is evident, problem may be a damaged filter
element, incorrect element fit or the need for cleaning and/or repair of gasketed surfaces.
WARNING

air against human skin. Make sure air stream is directed away from user and other personnel in the area.
Wear protective goggles or face shield. Failure to follow this warning may cause injury to personnel.

ment of secondary filter after three cleanings.
