(3) Bolts, Nuts, and Screws. Check them all for obvious looseness, missing, bent, or broken
condition. You can’t try them all with a tool, but look for chipped paint, bare metal, or rust around bolt heads.
If you find a bolt, nut, or screw you think is loose, tighten it or report it to your supervisor.
(4) 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.
(5) Electric Wires and Connectors, Look for cracked, frayed, or broken insulation, bare wires, and
loose or broken connectors. Tighten loose connectors. Report any damaged wires to your supervisor.
(6) Hoses and Fluid Lines. Look for wear, damage, and leaks, and make sure clamps and fittings
are tight. Wet spots show 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, report it to your supervisor.
4-6.1 CLEANING AGENTS
WARNING
• DO NOT use diesel fuel, gasoline, or benzene (benzol) for cleaning.
• DO NOT SMOKE when using cleaning solvent. NEVER USE IT NEAR AN OPEN
FLAME. Be sure there is a fire extinguisher nearby and use cleaning solvent only in well-
ventilated places. Flash point of solvent is 138°F (60°C).
• USE CAUTION when using cleaning solvents. Cleaning solvents evaporate quickly and
can irritate exposed skin if solvents contact skin. In cold weather, contact of exposed skin
with cleaning solvents can cause frostbite.
a. Treating Mildewed Areas. Canvas that has mildewed can be cleaned by scrubbing with a dry
brush. If it is necessary to use water to remove dirt, it should not be used until mildew has been removed.
After removing mildew, examine fabric. Look for evidence of deterioration. If canvas has deteriorated, it
should be replaced.
WARNING
Use only those authorized cleaning solvents or agents listed in Appendix E.
b. Cleaning Rust or Grease. When cleaning grease buildup or rusty places, use a cleaning solvent.
Then apply a thin coat of light oil to affected area.
