prior to adding more oil.
Oil replenishment is accomplished as follows:
1. Note the oil quantity on the oil replenishment tank gauge.
2. The system power switch is selected ON, illuminating the green ON light.
3. The ENG OIL PRESS TO TEST switch/light is activated to illuminate (test) the
green LH (RH)-FULL indications.
4. The selector valve is rotated to the L or R position as required to pump oil from the
oil replenishment tank to the associated engine oil tank
5. The selector valve is released when the pump automatically shuts off and the LH
(RH)- FULL legend illuminates. A full level is indicated by the illumination of the
respective side green light (LH FULL or RH FULL).
6. The system power switch is selected OFF.
7. Oil quantity used for each engine is noted.

Note:
Engine oil level should be checked within 15 minutes to two hours after engine shutdown
The engines must be dry-motored if the replenishment period is exceeded.

Engine Bleed Air System
Description
Engine bleed air is extracted from the 7th, 10th and 14th stages of the engine
compressor and used by the airplane systems below:
• 7th stage: Pressurization of oil seals and the venting of engine sumps in the
lubrication system
• 10th stage: Pneumatic supply to the air conditioning and pressurization systems,
and engine starting
• 14th stage: Pneumatic supply to the engine cowl and wing anti-ice systems, or
thrust reverser systems
Components and Operation
Ducting and check valves are used to direct the flow of bleed air from the engine to the
10th- and 14th-stage bleed air manifolds. The nacelle and pylon ducts are monitored
for bleed air leakage by the engine fire and jet pipe overheat detection systems.
For additional information, refer to Chapter 9 Fire Protection and Chapter 19
Pneumatic System.
