Hoses and fluid lines -Look for wear, damage, and leaks and ensure clamps and fittings are tight. Wet spots
show leaks, of course. But a stain around a fitting or connector can mean a leak. If a leak comes from a
loose fitting or connector, tighten it. If something is broken or worn out, report it to unit maintenance.
f.
Classification of Fluid Leaks. It is necessary for you to know how fluid leakage affects the status of your
vehicle. The following definitions of the types or classes of leaks you need to know to be able to determine the
status of your vehicle. Learn, then be familiar with them and remember-when in doubt, notify your supervisor!
CAUTION
· Equipment operation is allowable with minor leakages (class I or II). Of course,
consideration must be given to the fluid capacity in the item or system being
checked or inspected. When In doubt, notify your supervisor.
· When operating with class I or II leaks, continue to check fluid levels as required
in PMCS.
· Class III leaks should be reported to your supervisor or to unit maintenance for
corrective action.
Class I
Seepage of fluid (as indicted 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 or inspected.
Class III
Leakage of fluid great enough to form drops that fall from the item being checked or
inspected.
