OPERATOR/ CREW PREVENTIVE MAINTENANCE CHECKS AND SERVICES - Continued
It is necessary for you to know how fluid leaks affect the status of the trailer. The following are definitions of the
types/classes of leakage needed to determine the status of the trailer. Become familiar with them. When in
doubt, notify your supervisor.
Class I Seepage of fluid (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 fall.
Class Ill Leakage of fluid great enough to form drops that fall.
When operating with class I or II leaks, check fluid levels more often than that required in the PMCS.
Equipment operation is allowable with minor leaks (class I or II). Notify your supervisor when in doubt.
Class Ill leaks must be reported to your supervisor or Organizational maintenance.
