GENERAL PMCS PROCEDURES
1. Always perform PMCS in the same order so it gets to be a habit. Once you've had some practice,
you'll spot anything wrong in a hurry. If any deficiency is discovered, perform the appropriate
troubleshooting task in Chapter 4. If any component or system is not serviceable, or if the given service
does not correct the deficiency, notify your supervisor.
2. Before performing preventive maintenance, read all the checks required for the applicable interval
and prepare all tools needed to make all checks. Have several clean rags (Item 10, WP 0085)
handy. Perform ALL inspections at the applicable interval.
a. Keep It Clean. Dirt, grease, oil, and debris get in the way and may cover up a serious
problem. Clean as you work and as needed. Use dry cleaning solvent (Item 14, WP 0085)
on all metal surfaces. Use detergent (Item 4, WP 0085) and water when you clean rubber,
plastic, and painted surfaces.
(1) Be alert for deterioration of plastic and rubber materials. Report it to your
(2) Check metal parts for rust and corrosion. If any bare metal or corrosion exists, clean
and apply a light coat of lubricating oil (Item 9, WP 0085). Report it to your
Bolts, Nuts, and Screws. Check bolts, nuts, and screws for obvious looseness, missing,
bent, or broken condition. You can't try them all with a tool, but look for chipped paint, bare
metal, or rust around bolt heads. If you find one you think is loose, tighten it.
d. Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If you
find a bad weld, report it to your supervisor.
e. Electric Wires and Connectors. Look for cracked or broken insulation, break wires, and
loose or broken connectors. Tighten loose connectors and ensure that the wires are in good
Fluid Leakage. It is necessary for you to know how fluid leakage affects the status of your
towing device. The following are definitions of the types/classes of leakage you need to know
to be able to determine the status of your equipment. Learn and be familiar with them, and
remember - when in doubt, notify your supervisor.
