fifth wheel towing device. The following are definitions of the types/classes of leakage you
need to know to be able to determine the status of your equipment. Be familiar with them, and
remember - when in doubt, notify your supervisor.
Leakage Definitions of PMCS

Leakage indicated by wetness or discoloration, but not great
enough to form drops.
Class II
Leakage great enough to form drops, but not enough to cause
drops to drip from the item being checked/inspected.
Class III

CAUTION
Operation is allowable with Class I and Class II leakage. WHEN IN

must be reported immediately to your supervisor. Failure to do this
will result in damage to vehicle and/or components.
