Operation
The following procedural steps outlined are to be used only as a guide to replenish the engine oil
system. The Airplane Maintenance Manual takes precedence over all servicing procedures.
· Select the “POWER” switch on the oil replenishment panel, “SYSTEM ON” legend on.
· Confirm that the “LO OIL” lamp on the oil replenishment panel corresponds to the condition
indicated on EICAS “L−R OIL LO QTY” caution message.
· Select the switch labeled “LH or RH ENG” on the oil replenishment panel.
· Confirm that the “PUMP ON” (below reservoir label) and “VLV OPEN” (below the engine to
be filled) legends are displayed on the oil replenishment panel.
· Monitor the oil level on EICAS for both the engine and reservoir (example: if approximately 1
US quart is added to the engine, the oil replenishment tank level should have reduced by the
same amount).
· When the engine reaches maximum level confirm that the “PUMP ON” legend on the oil
replenishment panel goes out (indicating pump stops). Also confirm that the “VLV OPEN”
legend on the oil replenishment panel goes out (indicating valve closed).

ENGINE FUEL SYSTEM
The fuel system provides engine fuel for combustion, HP compressor Variable Stator Vanes (VSV)
actuation and engine oil cooling.
The main components that are contained in the fuel system are as follows:
· Fuel Pump Unit − The fuel pump unit contains both the LP and HP pumps. Fuel supplied from
the airplane fuel system passes through the (centrifugal type) LP pump, is pressurized and is
delivered to the Fuel Cooled Oil Cooler (FCOC).
· LP Filter − Fuel from the FCOC enters the LP fuel filter, where any debris is trapped before
