Operation
7.If you are flushing:
a.Run the pump long enough to thoroughly clean the pump and hoses.
b.Close the fluid control device and air regulator
(D).
c.Remove the suction hose (S) from the solvent and place it in the fluid to be pumped.
8.If you are going to use the pump:
a.Start the pump. Be sure the suction hose is in the supply container.
b.If you are using this pump to spray fluid, re- lieve the pressure, then install a spray tip in the gun. Trigger the gun into a grounded metal waste container to prime the hose. Adjust the pump pressure just enough to completely at- omize the fluid. Higher pressures cause pre- mature spray tip and pump wear.
WARNING
PRESSURIZED EQUIPMENT HAZARD
To reduce the risk of a serious injury whenever you are instructed to relieve pressure, follow the Pres- sure Relief Procedure on page 10.
c.In a direct supply system, the pump will start and stop as the spray gun, dispensing valve, or fluid outlet valve is opened and closed.
d.In a circulating system, the pump runs continu- ously and speeds up or slows down as supply demands until the air supply is shut off.

CAUTION
Never allow the pump to run dry of fluid. A dry pump will accelerate to a high speed, possibly damaging itself. If your pump accelerates quickly, or is running too fast, stop it immediately and check the fluid supply. If the supply is empty and air has been pumped into the lines, refill the container and prime the pump and lines with fluid, or flush and leave filled with compatible solvent. Be sure to eliminate all air from the system. A Pump Runaway Valve, Part No. 224040, is available.
9.If you are shutting down the pump:
a.Flush the pump before shutting down, espe- cially if pumping a material that will set up.
b.Remove the suction hose from the fluid con- tainer and run the pump until the fluid is forced out of the system, then shut off the air supply immediately.
c.Relieve the pressure.

PRESSURIZED EQUIPMENT HAZARD
To reduce the risk of a serious injury whenever you are instructed to relieve pressure, follow the Pres- sure Relief Procedure on page 10.
d.Refer to the Maintenance instructions on page 14.
