GENERAL PMCS PROCEDURES - CONTINUED
CAUTION
Operation is allowable with Class I and Class II leakage. WHEN IN DOUBT, NOTIFY YOUR SUPERVI-
SOR. When operating with Class I or Class II leaks, check fluid levels more frequently. Class III leaks must
be reported immediately to your supervisor. Failure to do this will result in damage to machine and/or com-
ponents.
NOTE
Notify Organizational Maintenance of any leaks the operator cannot fix.
Leakage Definitions for PMCS
Class I
Leakage indicated by wetness or discoloration, but not great enough to form
drops.
Class II

GENERAL LUBRICATION PROCEDURES
007 00
NOTE
Lubrication instructions contained in this PMCS are mandatory.
Overall views of lubrication points are located at the end of this work package.
Refer to FM 9-207 for lubrication in arctic operation.
1.
Included in this PMCS are lubrication services to be performed by the operator.
2.
Lubrication intervals are based on normal operation. Lubricate more during constant use and less during inactive peri-
ods. Use correct grade of lubricant for seasonal temperature expected (Refer to KEY on pages 0011 00-4 and 0011 00-5).
3.
For equipment under manufacturer's warranty, hardtime intervals shall be followed. Shorten intervals if lubricants are
known to be contaminated or if operation is under adverse conditions (e.g., longer than usual operating hours, extended
idling periods, extreme dust, etc.).
4.
Keep all lubricants in an environmental storage 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 lubrication
equipment clean and ready for use. Clean top of container before opening.
WARNING
Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and low toxic 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 do so may cause injury or death
to personnel.
5.
Clean area around lubrication points with solvent cleaning compound (Item 2, WP 0016 00) or equivalent before lubri-
cating equipment. Keep all external parts of equipment not requiring lubrication free of lubricants. After lubrication,
wipe off excess lubricant to prevent accumulation of foreign matter.
6.
Maintain a record of lubrication performed and report any problems noted during lubrication. Refer to DA PAM 750-8
for forms and procedures to record and report any findings.
