Section IV. LUBRICATION INSTRUCTIONS

INTERVALS AND MAN-HOURS

Intervals (on-condition or hard time) and the related man-hour times are based on normal operation. The

man-hour time specified is the time you need to do the services prescribed for a particular interval. On-

condition (OC) oil sample intervals shall be applied unless changed by the Army Oil Analysis Program

(AOAP) laboratory. Change the hard time interval if your lubricants are contaminated or if you are operating

the equipment under adverse operating conditions, including longer-than-usual operating hours. The hard

time interval may be extended during periods of low activity. If extended, adequate preservation precautions

must be taken. Hard time intervals will be applied in the event AOAP laboratory support is not available.

flame or in excessive heat.

Clean fittings before lubricating. Clean parts with drycleaning solvent (SD) type II, or equivalent. Dry before
