CAUTION: IF YOU THINK THERE ARE FUEL FUMES WHEN YOU REMOVE THE OIL
_______ FILLER CAP, IMMEDIATELY DO THE FAULT ISOLATION PROCEDURE "OIL QUANTITY INDICATION HIGHER THAN EXPECTED OR RISING" (FIM 79-31-00/101). USE ONE OF THESE METHODS TO FIND IF FUEL HAS CONTAMINATED THE OIL SYSTEM.
METHOD 1: USE A DRAEGER HAND PUMP (RR 1013832), WITH A HYDROCARBON 2 TUBE (RR 1013833) TO DO A CHECK FOR THE FUEL FUMES. USE THE MANUFACTURER'S INSTRUCTIONS TO DO THIS CHECK.
METHOD 2: USE A COMBUSTIBLE GAS DETECTOR (RR 1018157) TO DO A CHECK FOR THE FUEL FUMES. DO THE PROCEDURE THAT FOLLOWS TO DO THIS CHECK.
(1) Remove the gravity filler cap.
(a) If you smell fuel in the oil when the oil filler is opened or the oil quantity is abnormally high, then you must do this procedure: 'Use the Combustable Gas Detector to Detect the Fuel Vapor in the Oil'.
S 613-016
(2) Pour the oil into the oil filler opening.
(a) Add the oil until the oil level in the oil quantity sight glass shows FULL.
S 413-017
(3) Install the gravity filler cap.
