FWILER? SffW CW^ CLEAN'M or CW M Except for you-the operator-just about lite nimol important thing on a piece of equipment is the - filter. "How come?" you ask. Look at it this way: That filter on our equip- -. ment is there like a policeman to protect -- your equipment from its worst einemn -Dirl. Dirt is the big, big equipment killer. It gets inside, on and around everything ..- and does its murderous work. A fe t ounces inside a big engine like on a tank or dozer, and that engine' AN dead, shot. Filters are put on your equipment to stop this. You have air filters to clean dirt from the air that goes into things like engines and electronic equipment. You have fuel filters to keep dirt, water and other goop out of the delicate parts of en- gines. And you have oil filters to trap dirt that gets in engine oils and hydraulic fluids. Your job is to make sure tIhe l filters do their job. It's real -ini- ple: Clean them or change them- ju-t like your tech manual says. The niore . loose dirt there is around your area. the more often you'll have to clean or change. Do it as often as need be to make i sure your equipment stays ill Ihe fight. sie PREVENTIVE MAINTENANCE MuNinrL issue Ilo 19b 1969 Series IN THIS ISSUE S FIREPOWER 2-19 1 MIO.MIscSPHom.ar 214 M16A1 15-11 AIR MOBILITY 37-47 Helmet Tape 37 XM64 4 UH I 30-42 C147 44-47 ML-IOBjrometer 43 O-013 47 COMMUNICATIONS 48-54 Eulpmenl Contral IL 13A Piler Fn 52 Irque e4M9 IPII.Erlier l ,.p 52 H 189,GR Hedsel 50 AN GRC-106 53 1Xn.)n Seichlhhl 51 Cable RHil 53 AN PRC-2i 52 AN PPS5 54 Now*., -i; ru
