practice, you'll spot anything wrong in a hurry.
8. If anything looks wrong and you can't fix it, write it on your DA Form 2404 (Equipment Inspection and Maintenance
Worksheet). If you find some- thing seriously wrong, report it to organizational maintenance RIGHT NOW.
9. When you do your PREVENTIVE MAINTENANCE, take along the tools you need to make all the checks. You always
need a rag or two.
10. 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.

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, and report it to organizational maintenance.
12. Welds: Look for loose or chipped paint, rust or gaps where parts are welded together. If you find a bad weld, report it
