If anything looks wrong, write it on your DA Form 2404. Marine Corps users write it on your TM 4700-

15/1 E. If you find something seriously wrong, report it to Direct Support Maintenance RIGHT NOW.

When you do your PREVENTIVE MAINTENANCE, take along the tools you will need to make all the

checks. Take along a rag, you'll always need at least one.

WARNING

Clean all parts in a well ventilated area. Avoid inhaling solvent fumes and

prolonged exposure of the skin to cleaning solvent. Failure to do so can cause

severe injury or death. Do not use near flame or excessive heat. Flash point of

solvent is 100 to 138 (38 to 59 ).

(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 cleaning solvent (Item 6 App. E) on all

metal surfaces. Use soap and water when you clean rubber or plastic material.

(2)

Bolts, nuts and screws: Check them all for 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 can not 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, report it to maintenance supervisor.

CAUTION

Equipment operation is allowable with minor leakage (Class I or II). Of course,

consideration must be given to the fluid capacity in the item/system being

checked/inspected. When in doubt, NOTIFY YOUR SUPERVISOR!

When operating with Class I or II leaks, continue to check fluid levels as required

in your PMCS.

Class III leaks should be reported to your supervisor or Direct Support

Maintenance.
