PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS), INCLUDING
LUBRICATION INSTRUCTIONS Continued
Name, caution, and instruction plates should be easy to read. If they are dirty or corroded, clean them, and coat them with
lacquer. See TM 43-0319 for instructions.
If something doesnt work, troubleshoot it using the troubleshooting procedures (WP 0005 00).
Do the Semi-annual PMCS every 1500 miles (2414 km) of operation or 150 hours, whichever comes first, after the last
Semi-annual PMCS. Complete forms DA Form 2404 and DD Form 314.
Always do your PMCS in the same order so it gets to be a habit. With practice, youll spot anything that is wrong.
Keep your carrier clean. Dirt, grease, oil, and debris only get in the way, and may cover up a serious problem. Clean your
vehicle as you work and as needed.
After operation in water, mud, or loose sand, clean and lube carrier as soon as possible. Do not wait for next scheduled PMCS.
Use cleaning compound (WP 0542 00, Item 9) on metal surfaces. Use general purpose detergent (WP 0542 00, Item 16) and
water when you clean rubber or plastic parts.
You need to know how fluid leaks affect your vehicle. Definitions of the types and classes of leaks are given in General
Maintenance Instructions below. You need to know them to determine the condition of your vehicle. Learn them.
REMEMBER: WHEN IN DOUBT, NOTIFY YOUR SUPERVISOR!
The carrier may continue to operate with minor water or oil leaks (Class I or II). You must
consider how much fluid the item or system being checked or inspected can hold. When in
doubt, notify your supervisor. Any Class III leaks or any fuel leaks will make the carrier NOT
CLASS I Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops.
CLASS II Leakage of fluid great enough to form drops, but not enough to cause drops to drip from item being checked/
CLASS III Leakage of fluid great enough to form drops that fall from the item being checked/inspected.
