Dry cleaning solvent is flammable. Do not use near open flame or high
temperatures. Flash point temperature is 138o F (58oC). Injury to per-
sonnel and damage to equipment may result.
Keep it clean. Dirt, grease, oil and debris get in the way and may cover up a serious
problem. Clean while working as needed. Use dry cleaning solvent (Item 21, Appendix
D) to clean metal surfaces. Use soap (Item 2, Appendix D) and water when you clean
rubber or plastic material.
Bolts, nuts, and screws. Check them all for obvious looseness, missing, bent, or broken
condition. Do not try them all with a tool, but look for chipped paint, bare metal, or
rust around bolt head. If You find one loose, report it to organizational maintenance.
Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together.
If a bad weld is found, report it to organizational maintenance.
Electrical 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.
Hoses and fluid lines. Look for wear, damage, leaks, and make sure clamps and fittings
are tight. Wet spots show leaks, 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, report it to organizational maintenance.
