GENERAL
This section contains instructions for performing Operator/Crew PMCS on the M146 semitrailer shop

operation. Perform all checks and services at the specified intervals, keeping in mind the following
guidelines:
Before (B) PMCS is done before you operate the vehicle.
During (D) PMCS is done while the equipment and/or its component systems are in operation.
After (A) PMCS is done right after operating the vehicle.

SPECIAL INSTRUCTIONS
If something doesn't work, troubleshoot it with the instructions in this manual.
Always do your preventive maintenance in the same order so it gets to be a habit. Once you've had
some practice, you'll spot anything wrong in a hurry. When you do your preventive maintenance,
take along a rag or two.
While performing PMCS, observe WARNING and CAUTION paragraphs preceding those operations
which could endanger your safety or result in damage to the equipment.
If anything looks wrong and you can't fix it, write it on your DA Form 2404 and report it to Organizational
Maintenance RIGHT AWAY.
WARNING
Drycleaning solvent PD-680 is both toxic and flammable. Avoid prolonged breathing of
vapors, and avoid skin contact. Use only in well-ventilated area, and keep away from
open flame or excessive heat. Injury to personnel could occur.
Keep the equipment 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.
