i. When you do your PREVENTIVE MAINTENANCE, take along the tools you need
to make all the checks. You always need a rag or two.
Keep it clean - Dirt, grease, oil, and debris only get in the way and may cover up
a serious problem. Clean as you work and as needed. Use drycleaning solvent (SD-2)
on all metal surfaces. Use soap and water when you clean rubber or plastic materials.
Bolts, nuts and screws - Check them all for obvious looseness; missing, bent or broken
condition. You cant 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,
or report it to organizational maintenance.
Welds - Look for loose or chipped paint, rust, or gaps where parts are welded together.
If you find a bad weld, report it to organizational maintenance.
Electric 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, and leaks, and make sure clamps
and fittings are tight. Wet spots show leaks, of course. 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.
Fluid leakage - It is necessary for you to know how fluid leakage affects the status
of your vehicle. The following are definitions of the types/classes of leakage an operator
or crew member needs to know to be able to determine the status of his/her vehicle.
Learn, then be familiar with them and REMEMBER - WHEN IN DOUBT, NOTIFY
