Lubrication Introduction.

Intervals (on-condition or hardtime) and the related man-hour times are based on

normal operation. The man-hour time specified is the time needed to do all 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 hardtime interval if lubricants are contaminated or if

operating the equipment under adverse operating conditions, including longer-than-

usual operating hours. The calendar interval may be extended during periods of low

activity. If extended, adequate preservation precautions must be taken. Hardtime

intervals must be applied during the warranty period.

WARNING

protective goggles, face shield, and gloves; use only in a

well-ventilated area; avoid contact with skin, eyes, and

clothes; and do not breathe vapors. Keep away from heat or

flame. Never smoke when using solvent. The flash point for

Type II Dry-cleaning Solvent is 140F (60C) and Type III

Dry-cleaning Solvent is 200F (93C). Failure to do so may

result in injury or death to personnel.

Cleaning fittings before lubrication. Clean parts with dry-cleaning solvent

(SD P-D-680) or equivalent. Dry before lubricating.

grease fittings and oil can points outside and underneath vehicle.
