GENERAL PMCS PROCEDURES
00011
1. Intervals (on-condition or hardtime) and the related manhour times are based on normal operation. The man-
hour time specified is the time you need to do all the services prescribed for a particular interval. Change the
hardtime interval if your lubricants are contaminated or if you are operating the equipment under adverse oper-
ating conditions, including longer-than-usual operating hours. The hardtime interval may be extended during
periods of low activity. If extended, adequate preservation precautions must be taken.
WARN I N G
Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and
low-toxicity material. However, it may be irritating to the eyes and skin. Use protective
gloves and goggles. Use in well-ventilated areas. Keep away from open flames and other
sources of ignition. Failure to follow this warning may cause injury or death to personnel.
2. The lowest level of maintenance authorized to lubricate a point is indicated by one of the following symbols as
appropriate: Operator/Crew (C).
3. The time specified is the time required to perform all services at the particular interval (on-condition or hard-
time).
N OT E
When equipment is scheduled for PMCS other than daily services, you must also perform
all earlier PMCS procedures. For example, if you are performing the 1,000-hour interval,
you would also perform all steps included in the daily, 50-hour, 250-hour, and 500-hour
maintenance intervals.
