4. Procedure
_________ (Ref. Fig. 301/TASK 49-90-00-991-003, 302/TASK 49-90-00-991-005) NOTE : There are two alternatives to replenish the APU. Both, the gravity or
____ pressure fill procedure are described in the subsequent procedure.
Subtask 49-90-00-612-056
A. Check Oil Level and Replenish (Gravity Fill Procedure)
WARNING : USE THE CORRECT PERSONAL PROTECTION.
_______ OIL CAN HAVE ADDITIVE CALLED TRICRESYL PHOSPHATE IN IT. THIS CHEMICAL IS AN ASPHYXIANT, IT IS POISONOUS AND CAN BE ABSORBED THROUGH THE SKIN. USE CARE WHEN ENGINE OIL IS DRAINED. HOT OIL CAN POSSIBLY CAUSE BAD BURNS.
CAUTION : MAKE SURE THAT ALL PLUMBING IS FREE FROM OBSTRUCTION.
_______
(1)
Do an oil level check on the oil sight glass. NOTE : If the oil level is at the FULL mark on the oil sight glass,
____
do not add oil to the APU oil reservoir.
(2)
Put the container in position below the APU gear box to collect oil leakage.
(3)
Make sure that the oil scupper and the oil filler cap are clean. Make them clean with a lint-free cloth, if they are dirty.
(4)
Open the oil filler cap. WARNING : BE CAREFUL WHEN YOU DRAIN THE ENGINE OIL AND/OR LOOSEN THE
_______ FILLER CAP. HOT OIL CAN SPILL PAST THE FILLER CAP WHEN THE OIL LEVEL IS ABOVE THE 'ADD' RANGE (MARKED ON THE SIGHT GLASS).
CAUTION : MAKE SURE THAT ALL PLUMBING IS FREE FROM OBSTRUCTION.
