Start Up and Adjust Pump
Keep hands and fingers away from the priming piston during operation and whenever the pump is charged with air. The priming piston extends beyond the intake housing to pull material into the pump and can ampu- tate a hand or finger caught between it and the intake housing. Follow the Pressure Relief Procedure on page 13 before checking, clearing, or cleaning the priming piston.
1.Supply fluid to the pump, per the requirements of your system.
2.Be sure the pump air regulator (H) is closed.
3.Open the
4.Hold a metal part of the valve firmly to the side of a grounded metal pail and hold the trigger open.
5.Adjust the pump air regulator (H) until the pump starts.
6.Cycle the pump slowly until all air is pushed out and the pump and hoses are fully primed.
7.Release the valve trigger and lock the trigger safety. The pump should stall against pressure.
8.Use the pump air regulator to control the pump speed and the fluid pressure. Always use the lowest pressure necessary to get the desired results. Higher pressures cause premature nozzle and pump wear.

1.Supply fluid to the pump, per the requirements of your system.
2.Open the dispensing valve(s).
3.To adjust the system, perform the following proce- dure:
a.Turn on the hydraulic power supply.
b.Open the flow control valve (H) all the way.
c.Adjust the
d.Count the cycle rate of the pump.
e.Close the flow control valve (H) 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 hydrau- lic controls ensures proper pump operation and will prevent pump runaway and damage if the fluid supply runs out.
