services listed in the PMCS table. Covering unused receptacles, stowing unused accessories, and other
routine procedures such as equipment inventory, cleaning components, and touch-up painting are not listed
in the table. These are things you should do any time you see that they need to be done. If a routine check
is listed in the PMCS table, it is because experience has shown that problems may occur with this item. Take
along the tools and cleaning cloths needed to perform the required checks and services. Use the information
in the following paragraphs to help you identify problems at any time. Use the following information to help
identify potential problems before and during checks and services.
a. Keep it clean. Dirt, grease, and oil get in the way and may cover up a serious problem. Use dry
cleaning solvent to clean metal surfaces.
b. Use soap and water to clean rubber or plastic parts and material.
c. Check all bolts, nuts, and screws to make sure they are not loose, missing, bent, or broken. Do not
try to check them with a tool, but look for chipped paint, bare metal, or rust around bolt heads. If
you find one loose, report it to the next higher level of maintenance.
d. Inspect welds for loose or chipped paint, rust, or gaps where parts are welded together. If a broken
weld is found, report it to the next higher level of maintenance.
e. Inspect electrical wires, connectors, terminals, and receptacles for cracked or broken insulation,
bare wires, and loose or broken connectors. Tighten loose connectors. Examine terminals and
receptacles for serviceability. If deficiencies are found, report them to the next higher level of
maintenance.
WARNING
Dry cleaning solvent used to clean parts is potentially
dangerous to personnel and property. Clean parts in a
well-ventilated area. Avoid inhalation of solvent
fumes. Wear goggles and rubber gloves to protect
eyes and skin. Wash exposed skin thoroughly. Do
not smoke or use near open flame or excessive heat.
Failure to observe this warning can cause severe
injury to personnel or DEATH.
CAUTION
Keep cleaning solvents, gasoline and lubricants away
from rubber or soft plastic parts. They will deteriorate
material.
