(c)
Welds: Look for loose or chipped paint, rust or gaps where parts are welded
together. If you find a bad weld, report it to you supervisor.
(d)
Electric wires and connectors: Look for cracked or broken insulation, bare
wires and loose or broken connectors. Tighten loose connections and make sure
the wires are in good condition.
(e)
Hoses and fluid lines: Look for wear, damage, and leaks. Make sure
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, either correct it or report
it to your supervisor
(f)
Leakage: It is necessary for you to know how fluid leaks affect the status of
your equipment. 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 IN DOUBT, NOTIFY YOUR
SUPERVISOR.
CAUTION
. Equipment operation is allowable with minor leakages (Class I or
II). Of course, you must consider the fluid capacity in the
item/system being checked/inspected.
. When operating with Class I or Class II leaks, continue to check
fluid levels as required in your PMCS.
. Class III leaks should be reported to your supervisor.
CLASS I
CLASS II
CLASS III
