Keep It Clean. Dirt, grease, oil, and debris get in the way and may cover up a serious problem. Clean as you work
and as needed. Use Cleaning compound, solvent, type III (Item 7, WP 0233 00) on all metal surfaces. Use Deter-

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 fur-

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.
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.
Electric Wires and Connectors. Look for cracked or broken insulation, bare wires, and loose or broken connec-
tors. Reconnect loose connectors. Ensure wires are in good condition.
Hoses and Fluid Lines. Look for wear, damage, and signs of leaks. Check for loose clamps and fittings. Wet spots

connector, tighten it. If something is broken or worn out, correct it if authorized by the Maintenance Allocation
