Preventative Maintenance (PMCS) of Tactical vehicle (HMMVEE)

PMCS (Preventative Maintenance Check and Services)- Thorough inspection of any tactical vehicle prior and

after operating any tactical vehicles. - Failure to conduct PMCS of vehicles can lead to dire

consequences.

1.) Leaks

HUMVEE1.) Leaks - Check both front and side exterior for any leaks. Any leaks detected must be further investigated before further continuation of PMCS. Check underneath for any evidence as well.

Examples

Types of leaks

The amount of leakage is designated by three categories of leaks.Class 1 – Leakage indicated by wetness or discoloration, not great enough to form drops.Class 2 – Leakage great enough to form drops, but not enough to cause drip from item being checked/inspected.Class 3 – Leakage great enough to form drops that fall from the item being checked/inspected

CAUTION

Operating the HUMVEE is allowable only with class 1 or 2 leakage except for the brake system. However, more frequent checks must be made!
