General Maintenance Procedures.
a. Cleanliness - Dirt, grease, oil, and debris only get in the way and may cover up a serious problem. Clean as you
work and as needed. Use dry cleaning solvent (SD-2) on all metal surfaces.
WARNING
Dry cleaning solvent, SD-2, used to clean parts is potentially dangerous to personnel and property. Do not
use near open flame or excessive heat. Flash point of solvent is 138F.
b.
Bolts, nuts, and screws - Check them all for obvious looseness, missing, bent, or broken condition. You can’t try
them all with a tool, of course, but look for chipped paint, bare metal, or rust around bolt heads. If you find one you think is
loose, tighten it, or report it to Organizational Maintenance.
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 Organizational Maintenance.
d.
Electric wires and connectors - Look for cracked or broken insulation, bare wires, and loose or broken connectors.
Tighten loose connectors and make sure the wires are in good shape.
e.
Hydraulic lines and fittings - Look for wear, damage, leaks, and make sure clamps and fittings are tight. Wet
spots 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 Organizational Maintenance.

Fluid Leakage.
It is necessary for you to know how fluid leakage affects the status of the hydraulic system. The following are definitions of
the types/classes of leakage you need to know to be able to determine the status of the dump body. Learn, then be
familiar with them and REMEMBER - WHEN IN DOUBT, NOTIFY YOUR SUPERVISOR!
Leakage Definitions for Crew/Operator PMCS
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/sistem being checked/inspected. When in doubt, notify your
supervisor.
When operating with Class I or II leaks, continue to check fluid levels as required in your PMCS.
Class III leaks should be reported to your supervisor or to Organizational Maintenance.
