Equipment operation is allowable with minor leakage (Class I or II) of any fluid except
fuel. Of course, consideration must be given to the fluid capacity in the item being
checked/inspected. When in doubt, notify your supervisor.
When operating with Class I or II leaks, continue to check fluid level more often than
required in the PMCS. Parts without fluid will stop working and/or cause equipment
Class Ill leaks should be reported to your supervisor or unit maintenance.
If the equipment must be kept in continuous operation, check and service only those
items that can be checked and serviced without disturbing operation. Make the complete
checks and services when the equipment can be shut down.
Within designated interval, these checks are to be performed in the order listed.
Table 3-2. Operator/Crew Preventive Maintenance Checks and Services (PMCS).
