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.
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.
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.
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.
LOCK
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.
