8. If anything looks wrong and you can't fix it, write it on your DA Form 2404. If you find something seriously wrong,

report it to organizational maintenance RIGHT NOW.

9. When you do your PREVENTIVE MAINTENANCE, take along the tools you will need to make all the checks. Take

along a rag, you'll always need at least one.

A - 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 dry cleaning solvent (SD-2) on all metal surfaces. Use soap and water when you clean rubber

or plastic material.

B - Bolts, nuts, and screws: Check them all for obvious looseness, missing, bent or broken condition. 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, or report it to organizational maintenance if you can not tighten it.

C - 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.
