PREVENTIVE MAINTENANCE CHECKS AND SERVICES (CONT)

WARNING

Dry cleaning solvent (P-D-680), used to clean parts is toxic and flammable. Wear

protective goggles and gloves and use only in a well ventilated area. Avoid

contact with skin, eyes, and clothes and don't breathe vapors. Do not use near

open flame or excessive heat and don't smoke when using it. Failure to do so

could cause serious injury. If you become dizzy while using cleaning solvent, get

fresh air and medical attention immediately. If contact with skin or clothes is

made, flush with large amounts of water. If contact with eyes is made, wash eyes

with water and seek medical aid immediately.

Compressed air used for cleaning purposes will not exceed 30 psi. Use only with

effective chip guarding and personal protective equipment (goggles/shield,

gloves, etc).

(1) Keep it clean: Dirt, grease, oil, and debris only get in the way and may cover up a serious problem. Clean as

you work and as needed. Use dry cleaning solvent P-D-680 on all metal surfaces. Use soap and water when you clean

rubber or plastic material.

(2) Bolts, nuts, and screws: Check them 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 direct support maintenance if you cannot tighten it.

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

report it to direct support maintenance.

(4) 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.

(5) 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, either correct it or report it to direct support

maintenance (refer to maintenance allocation chart).

It is necessary for you to know how fluid leakage affects the status of your vehicle. The following are

definitions of the types/classes of leakage you need to know to be able to determine the status of your vehicle. Learn, then

be familiar with them and REMEMBER - WHEN IN DOUBT, NOTIFY YOUR SUPERVISOR!
