Operation
Hydraulic–Powered Systems
Refer to the warnings on page 13.
1. Supply fluid to the pump, per the requirements of
your system.
2. Open the shutoff valves between the pump and
supply tanks.
3. Open the dispensing valve(s) or spray gun(s).
4. To adjust the system, perform the following proce-
dure:
a. Turn on the hydraulic power supply.
b. Open the flow control valve all the way.
c. Adjust the pressure–reducing valve until you
get the desired fluid pressure. Run the pump
until all air is purged from the fluid lines.
d. Count the cycle rate of the pump.
e. Close the flow control valve until the cycle rate
and fluid pressure start to drop.
f. Open the flow control valve slightly until the
cycle rate and fluid pressure return to the
desired level. This method of setting the hy-
draulic controls ensures proper pump opera-
tion and will prevent pump runaway and dam-
age if the fluid supply runs out.
g. Close the gun or valve.
