2-9. CLASS LEAKAGE DEFINITIONS

Wetness around seals, gaskets, fittings, or connections indicates leakage. A stain

also denotes leakage. If a fitting or connector is loose, tighten it. If broken or defec-

tive, report it. Use the following as a guide:

a. Class I. Leakage indicated by wetness or discoloration not great enough to

form drops.

b. Class II. Leakage great enough to form drops but not enough to cause drip

from item being checked/inspected.

c. Class III. Leakage great enough to form drops that fall from the item being

checked/inspected.

CAUTION

Operation is allowable with Class I or II leakage except for brake

and fuel system. Any brake fluid or fuel leakage must be report-

ed. WHEN IN DOUBT, NOTIFY YOUR SUPERVISOR. When

operating with Class I or II leaks, check fluid levels more fre-

quently. Class III leaks must be reported to your supervisor or to

unit maintenance. Failure to do this may result in damage to

vehicle and/or components.
