Operation Instructions
It is the responsibility of all persons performing the operation of the HASCO Valve to
read and understand this procedure before starting work. Before using a Girard valve
with a hydraulic actuator installed, follow the procedure for bleeding hydraulic lines,
located in the Installation Instructions section of this manual.
This valve is remotely operated from ground level. The hydraulic pump applies pressure
to the valve, allowing it to open. When the hydraulic pressure is released, the HASCO
valve will cycle to the closed position.

With the HASCO Valve properly connected to the hydraulic pump and in the closed
position:
1. Rotate the hydraulic pump pressure release handle to the closed position (as
shown in Fig. C and Fig. D on page 11).
2. Actuate the hydraulic pump handle 5-7 times to open the valve. (See Fig. D on
page 11)
3. Rotate the pressure release handle to the open position to relieve hydraulic
pressure and close the valve.
