Starting and Adjusting the Pump

1.Connect the suction kit (K) to the pump's fluid inlet, and place the tube into the fluid supply.

2.Close the pump air regulator (D).

3.Open the pump's bleed-type master air valve (B).

4.Hold a metal part of the gun (T) firmly to the side of a grounded metal pail and hold the trigger open.

5.Slowly open the air regulator (D) 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 gun trigger and lock the trigger safety latch. The pump should stall against pressure.

Operation

8.If the pump fails to prime properly, open the drain valve (G). Use the drain valve as a priming valve until fluid flows from the valve. Close the drain valve when all air is eliminated.

OPENCLOSED

9.With the pump and lines primed, and with adequate air pressure and volume supplied, the pump will start and stop as you open and close the gun. In a circulating system, the pump will speed up or slow down on demand, until the air supply is shut off.

10.Use the air regulator to control the pump speed and the fluid pressure. Always use the lowest air pres- sure necessary to get the desired results. Higher pressures cause premature tip and pump wear.

CAUTION

Never allow the pump to run dry of the fluid being pumped. A dry pump will quickly accelerate to a high speed, possibly damaging itself. If your pump acceler- ates quickly, or is running too fast, stop it immediately and check the fluid supply. If the supply container is empty and air has been pumped into the lines, refill the container and prime the pump and the lines with fluid, or flush and leave it filled with a compatible sol- vent. Be sure to eliminate all air from the fluid system.

Shutdown and Care of the Pump

For a brief shutdown, relieve the pressure, page 12. Stop the pump at the bottom of its stroke to prevent fluid from drying on the exposed displacement rod and dam- aging the throat packings.

For a longer shutdown, or overnight, always flush the pump before the fluid dries on the displacement rod, page 14. Relieve the pressure, page 12.
