GENERAL
The dolly set must be inspected systematically to ensure that it is ready for operation at all times.
Inspection will allow defects to be discovered and corrected before they result in serious damage or
failure. This section contains a tabulated list of preventive maintenance checks and services to be
performed by organizational maintenance personnel. All deficiencies and corrective actions taken
will be recorded on DA Form 2404.
1. Do your quarterly (Q) PMCS once every 3 months.
2. Do you semiannual (S) PMCS once every 6 months.
3. Do your annual (A) PMCS once every year.
If something doesn’t work, troubleshoot it with the instructions in this manual or notify your
supervisor.
Always do your preventive maintenance in the same order, so it gets to be a habit. Once you have
had some practice, you will quickly spot anything wrong.
SPECIAL INSTRUCTIONS
If anything looks wrong and you can’t fix it, describe it on your DA Form 2404. If you find something
seriously wrong, report the situation to direct support personnel promptly.
WARNING
Drycleaning solvent PD-680 is both toxic and flammable. Avoid prolonged breathing of
vapors and avoid skin contact. Use only in well ventilated areas and keep away from
open flame or excessive heat. Flash point of solvent is 138°F (58.8°C).
1. 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 PD-680 to clean metal
surfaces. Use soap and water when you clean rubber or plastic material.
2. Bolts, nuts, and screws: Check that they are not loose, missing, bent, or broken. You can't try
them all with a tool of course, but look for chipped paint, bare metal, or rust around boltheads.
Tighten any that you find loose.
3. Welds: Look for loose or chipped paints, rust, or gaps where parts are welded together. If you
find a bad weld, report it to direct support personnel.
