GENERAL PMCS PROCEDURES CONTINUED
Fluid Leakage. It is necessary for you to know how fluid leakage affects the status of your machine. The fol-
lowing are definitions of the types/classes of leakage you need to know to be able to determine the status of
your machine. Learn and be familiar with them and remember: when in doubt, notify your supervisor.
C AU T I O N
Operation is allowable with Class I and Class II leakage, except for fuel, where no leaks
are allowed. When in doubt, notify your supervisor. 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 components.
N OT E
Notify your supervisor of any leaks you cannot fix.
Leakage Definitions for Field PMCS
Class I
Leakage indicated by wetness or discoloration, but not great enough to
form drops.
Class II
Leakage great enough to form drops, but not enough to cause drops to
drip from the item being checked/inspected.
Class III
Leakage great enough to form drops that fall from the item being
checked/inspected.
GENERAL LUBRICATION PROCEDURES
0036
N OT E
Lubrication instructions contained in PMCS are MANDATORY.
Overall views of lubrication points are located at the end of this work package.
Localized views are provided following the overall views. Reference to these localized
views is provided from the overall views.
Recommended intervals are based on normal conditions of operation, temperature, and humidity. When oper-
ating under extreme conditions, such as high or low temperatures or exposure to sand or dust, lubricants
should always be changed more frequently. Lubricants that have become contaminated will be changed
regardless of interval. When in doubt, notify your supervisor.
Ensure all fluids drained as a result of lubrication or maintenance are collected in a suitable container and dis-
posed of IAW local policy and ordinances. Clean up any spills immediately.
Keep all lubricants in a closed container and store in a clean, dry place away from extreme heat or cold. Keep
container covers clean and do not allow dust, dirt, or other foreign material to mix with lubricants. Keep all lubri-
cation 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 750-8 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 lubrica-
tion fittings with a clean rag. After lubrication, wipe off excess oil or grease to prevent accumulation of foreign
matter.
Refer to FM 9-207, Operation and Maintenance of Ordnance Materiel in Cold Weather for lubrication instruc-
tions in cold weather.
Refer to AR 70-12, Fuels and Lubricants Standardization Policy for Equipment Design, Operation, and Logistic
Support, for use of standardized lubricants.
