PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
Maintenance Forms and Records
Every mission begins and ends with paperwork. There isn't much of it, but you have to keep it up. The forms
and records you fill out have several uses. They are a permanent record of the services, repairs, and
modifications made on your vehicle. They are reports to organizational maintenance and to your commander.
And they are a checklist for you when you want to know what is wrong with the vehicle after its last use, and
whether those faults have been fixed. For the information you need on forms and records, refer to TM 38-750.

Always do your PREVENTIVE MAINTENANCE 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 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 organizational maintenance RIGHT NOW.
When you do your PREVENTIVE MAINTENANCE, take along the tools you need to make all the
checks. You always need a rag or two.
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 SD-2 on all metal
surfaces. Use soap and water when you clean rubber or plastic material.
Dry-cleaning solvent, used to clean parts, is potentially dangerous to personnel and
property. Do not use near open flame or excessive heat. Flash point of solvent is
100 - 1380F.
Bolts, nuts, and screws: Check them all for obvious looseness, and 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 boltheads. If you find one you think is loose, tighten it, or report it to organiza-
tional maintenance if you can't tighten it.
