GENERAL PMCS PROCEDURES (Con’t).
(6)
Hoses and Fluid Lines. Look for wear, damage, and signs of leaks. Ensure that clamps
and fittings are tight. Wet spots indicate leaks, of course, but a stain around a fitting or connector can also 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 your
supervisor.
(7)
Fluid Leakage. It is necessary for you to know how fluid leakage affects the status of your
dump truck. The following are definitions of the types/classes of leakage you need to know to be able to determine
the status of your equipment. Learn and be familiar with them, and remember - when it doubt, notify your superv-
sor.
Leakage Definitions for PMCS
Class I
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
Leakage great enough to form drops that fall from the item being checked/
inspected.
Operation is allowable with Class I and Class II leakage. WHEN IN DOUBT, NOTIFY YOUR
SUPERVISOR. When operating with Class I or Class II leaks, check fluid levels more fre-
quently. Class Ill leaks must be reported immediately to your supervisor. Failure to do this
will result in damage to vehicle and/or components.
