Section II. OPERATOR'S PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)

2-3. GENERAL

a. Before you operate. Always keep in mind the CAUTIONS and WARNINGS. Perform your before PMCS.

b. While you operate. Always keep in mind the CAUTIONS and WARNINGS. Perform your during PMCS.

c. On a weekly basis. Be sure to perform your weekly PMCS.

d. If your equipment fails to operate. Troubleshoot with proper equipment. Report any deficiencies using the

proper forms. See DA PAM 738-750. Marine Corps users see TM 4700-15/1 E.

2-4. OPERATOR PMCS TABLE (Table 2-2.)

a. Always do your PREVENTIVE MAINTENANCE in the same order so that it gets to be a habit. Once you've had

some practice, you'll spot anything wrong in a hurry.

b. If anything looks wrong and you can't fix it, write it on your DA Form 2404. If you find something seriously wrong,

report it to unit maintenance RIGHT NOW.

c. When you do your PREVENTIVE MAINTENANCE, take along the tools you need to make all the checks. You

always need a rag or two.

d. Bolts, nuts and screws: Check them all for obvious looseness, missing, bent or broken condition. You can't try

them all with a tool, of course, but look for chipped paint, bare metal, or rust around bolt heads. If you find one

you think is loose, tighten it, or report it to unit maintenance if you can't tighten it.

e. Welds: Look for loose or chipped paint, rust, or gaps where parts are welded together. If you find a bad weld,

report it to unit maintenance.

f. Electric wires and connectors: Look for cracked or broken insulation, bare wires, and loose or broken connectors.

Tighten loose connectors and make sure the wires are in good shape.

g. Hoses and fluid lines: Look for wear, damage, and leaks, and make sure clamps and fittings are tight. Wet spots

show leaks, of course. But a stain around a fitting or connector can mean a leak. If a leak comes from a loose

fitting or connector, tighten it. If something is broken or worn out, report it to unit maintenance.
