Keep all lubricants in a closed container and store in a clean, dry place away from extreme heat. Keep container
covers clean and do not allow dust, dirt, or other foreign material to mix with lubricants. Keep all lubrication equipment
clean and ready for use.
Maintain a good record of all lubrication performed and report any problem noted during lubrication. Refer to DA
Pam 738-750 for maintenance forms and procedures to record and report any findings.
Keep all external parts of equipment not requiring lubrication free of lubricants. Before lubrication, wipe
lubrication fittings with a clean rag (Item 34, Appendix C). After lubrication, wipe off excess oil or grease to prevent
accumulation of foreign matter.
Refer to FM 9-207 for lubrication instructions in cold weather.
Refer to AR 70-12 for use of standardized fuels and lubricants.
Oil filters will be changed when:
they are known to be contaminated or clogged,
service is directed by Army Oil Analysis Program (AOAP) laboratory analysis, or
at prescribed hardtime intervals.
Engine oil, transmission fluid, and hydraulic fluid must be sampled initially at 90 days of operation as prescribed
by DA Pam 738-750. Thereafter, engine oil and transmission fluid are sampled semiannually and hydraulic fluid is
sampled annually, unless AOAP results dictate otherwise.
For equipment under manufacturer's warranty, hardtime oil service intervals shall be followed. Intervals shall be
shortened if lubricants are known to be contaminated or if operation is under adverse conditions (i.e., longer than usual
operating hours, extended idling periods, or extreme dust).
Dashed leader lines on illustrations related to lubrication indicate that lubrication is required on both sides of the
GENERAL PMCS PROCEDURES
Always perform PMCS 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. If any deficiency is discovered, perform the appropriate troubleshooting task in Chapter 3 of
this manual. If any component or system is not serviceable, or if the given service does not correct the deficiency, notify
Before performing preventive maintenance, read all the checks required for the applicable interval and prepare all
tools needed to make all checks. Have several clean rags (Item 34, Appendix C) handy. Perform ALL inspections at the
Dry cleaning solvent, P-D-680, Is toxic and flammable. Always wear protective
goggles and gloves, and use only in a well-ventilated area. Avoid contact with
skin, eyes, and clothes, and DO NOT breathe vapors. DO NOT use near open flame
or excessive heat. The solvent's flash point Is 100°F-138°F (38°C-59°C). If you
become dizzy while using cleaning solvent, immediately get fresh air and medical
help. If solvent contacts eyes, immediately wash your eyes and seek medical
