When a check/service procedure is required for both weekly and before intervals, it is not necessary to
perform the procedure twice if the equipment is operated during the weekly period.
COMMON CHECKS AND CLEANING
Always keep the equipment clean. Remove dirt, sand, and debris from all controls and hose connections.
Bolts, nuts, and screws
Check them for obvious looseness, missing, bent, or broken condition on equipment. If you find a bolt, nut,
or screw you think is loose, tighten it or report it to your supervisor.
Look for wear, damage, and leaks. Ensure clamps are tight. Wet spots show leaks, but a stain around a
fitting or connector can also mean a leak. If a leak comes from a loose fitting or coupling, tighten it. If
something is broken or worn out, report it to your supervisor.
LEAKAGE DEFINITION FOR PERFORMING PMCS
It is necessary for you to know how fluid leakage affects the status of the equipment. The following are the
types/classes of leakage an operator needs to know to be able to determine the status of the water
system. Learn these leakage definitions and remember - when in doubt, notify your supervisor.
Equipment operation is allowable with minor leakages (Class I or II). Of
course, consideration must be given to fluid capacity in the system.
When in doubt, notify your supervisor.
When operating with Class I, or II leaks, continue to check fluid levels as
required in your PMCS.
Class III leaks, cease all operations and report immediately to your
Class I - Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops.
Class II - Leakage of fluid great enough to form drops but not enough to cause drops to drip from item
Class III - Leakage of fluid great enough to form drops that fall from items being checked/inspected.
