 GROUND SERVICING SYSTEM - DESCRIPTION AND OPERATION
___________________________________________________
 1.  General (Fig. 1)_______
 A.  The ground servicing system fills all hydraulic reservoirs from one location. The system components are in the aft left wing/body fairing. The system has a hand pump with suction line and a connection for pressure fill from a ground cart. There is also a remote quantity indicator, a fill selector valve, and a fill filter module.
 2.  Component Details (Fig. 1)_________________
 A.  Reservoir Manual Fill Pump
 (1)  The manual fill pump is a hand pump used to service the hydraulic reservoirs when pressure fill equipment is not available. The pump handle is stowed in brackets adjacent to the pump.
 B.  Suction Hose
 (1)  One end of the suction hose is connected to the manual fill pump. The other end is placed in a container of hydraulic fluid. When not in use, the free end of the hose is stowed in the pump handle.
 C.  Pressure Fill Connection
 (1)  The pressure fill connection is below the manual fill pump. This connection is used to pressure fill the reservoirs from a ground cart. A protective cap covers the connection when not in use.
