General.

The hydraulic system of the test stand is comprised

of the hydraulic pump, high and low pressure filters, pressure gages,

flow indicator, and control valves.

The necessary interconnecting

hose assemblies and tubing are included for the hydraulic system to

perform its intended function of delivering filtered hydraulic fluid

at the desired volume and pressure, to the air craft hydraulic

system under test.

(A) Maintenance

The hydraulic system of the test stand must at all times

be free of leaks. The efficiency of the test stand will

be impaired if a leak exists anywhere in the system.

(B)

Component Removal

In the event that a component in the hydraulic system is

removed, all openings must be capped or plugged to pre-

vent entrance of foreign matter to the system.
