SECTION I. DESCRIPTION AND USE OF CONTROLS AND INSTRUMENTS.
2-1. Controls and instruments. The controls and instruments for the operation and monitoring of the test stand are
located at the operator's station at the rear of the stand.
2-2. The high pressure relief valve is located adjacent to the high pressure filter inside the access door on the right hand
side of the unit.
The item numbers used on the hydraulic schematic diagram, figure 1-4, are those assigned to the same components on
the unit and used on the marker plates on the control panel. Control settings are explained in table 2-2.
SECTION II. OPERATING PROCEDURES.
2-4. Personnel operating the test stand must be familiar with the location and function of all controls and indicators and
have a thorough knowledge of the principles of operation involved.
Extremely high hydraulic fluid pressures are developed during test stand operation. The
connecting hoses must be free of defects and the connection fittings clean to avoid hose
rupture or leaks.
2-5. Preliminary checks. Prior to test stand operation, the following steps should be taken to make certain that the stand
will operate properly and safely.
Use volatile solvents only in a well ventilated area. Avoid prolonged contact with the skin.
a. Inspect the connecting hoses and clean the fittings using a solvent conforming to specification PD-680, if
