problem. Clean as you work and as needed. Use dry cleaning solvent (Item 7, Appendix D) on all metal
surfaces. Use soap and water when you clean rubber or plastic material.

Perform the following inspections as described below:
(1) Bolts, nuts, and screws. Check for obvious looseness and missing, bent, or broken items. 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. If you can't tighten it, report itto unit maintenance.
(2) Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If you find a bad
weld, report it to unit maintenance.

connectors. Tighten loose connectors and ensure that the wires are in good condition.
(4) Hoses and fluid lines. Look for wear, damage, and leaks, and ensure that clamps and fittings are tight.
