Tighten looseclamps and connectors.Equipment operation is allow-able with minor leakages (classI or 11). Of course, you mustconsider the fluid capacity inthe item/system being checked/inspected. When in doubt, noti-fy unit maintenance personnel,When operating with class I orclass II leaks, continue to checkfluid levels as required in yourPMCS.Class Ill leaks should bereported to unit maintenancepersonnel.NOTEFluid leakage classificationsapply only to hull components.(4) Fluid leakage. Leaks are divided intothree classifications. Compare leak with thefollowing definitions:Class ISeepage of fluid (as in-dicated by wetness ordiscoloration) not greatenough to form drops.Class IILeakage of fluid greatenough to form drops butnot enough to causedrops to drip from itembeing checked/inspected.Class IllLeakage of fluid greatenough to form drops thatfall from the item beingchecked/inspected.d. If your equipment does not perform asrequired, refer to troubleshooting proceduresin chapter 3 for possible problems.
