GENERAL PMCS PROCEDURES CONTINUED
WARNING
When servicing this machine, performing maintenance or disposing of materials such as
engine coolant, hydraulic fluid, lubricants, battery acids or batteries, windshield cleaning
compound, and CARC paint, consult your unit/local hazardous waste disposal center or
safety office for local regulatory guidance. If further information is needed, please contact
The Army Environmental Hotline at 1-800-327-3845. Failure to follow this warning may
result in injury or death to personnel.
b. Hazardous Waste Disposal. Ensure all spills are cleaned up and disposed of IAW local policy and
ordinances.
c.
Rust and Corrosion. Check metal parts for rust and corrosion. If any bare metal or corrosion exists, clean
and apply a light coat of OE/HDO-30 lubricating oil. Report it to your supervisor.
d.
Bolts, Nuts, and Screws. Check bolts, nuts, and screws for obvious looseness, missing, bent, or broken
condition. You cannot try them all with a tool, but look for chipped paint, bare metal, or rust around bolt
heads. If you find one is loose, tighten it.
e.
Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If you find a bad
weld, report it to your supervisor.
f.
Electric Wires and Connectors. Look for cracked or broken insulation, bare wires, and loose or broken
connectors. Reconnect loose connectors. Ensure wires are in good condition.
g.
Hoses and Fluid Lines. Look for wear, damage, and signs of leaks. Check for loose clamps and fittings.
Wet spots indicate leaks, 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, correct it if authorized by the
Maintenance Allocation Chart (WP 0376). If not authorized, notify your supervisor.
h.
Fluid Leakage. It is necessary for you to know how fluid leakage affects the status of your machine. The
following are definitions of the types/classes of leakage you need to know to be able to determine the
status of your machine. Learn and be familiar with them and remember: when in doubt, notify your
supervisor.
CAUTION
Operation is allowable with Class I and Class II leakage, EXCEPT for fuel, where NO
leaks are allowed. WHEN IN DOUBT, NOTIFY YOUR SUPERVISOR. When operating
with Class I or Class II leaks, check fluid levels more frequently. Class III leaks must be
reported immediately to your supervisor. Failure to do this will result in damage to
machine and/or components.
NOTE
Notify your supervisor of any leaks you cannot fix.
