• Put 1 fullbag of primer in hopper
  • Add water 1/2 of the way up the cylinders.
  •  Put pump in reverse and pump 10 to 15 strokes to thoroughly active primer.
  • Put volume control to approximately 50% and put pump in forward. 
  • Turn pump on and as soon as it switches over, shut pump off.
  • If the s tube is on the left side, put the chute on the left side. If it is on the right side, put the chute on the right side.
  • Pour concrete into the hopper until it starts to come over the top of the s tube. You will notice the concrete pushing the water into the cylinder.
  • Turn on the pump. The opposite cylinder will draw the prime in first.
  • If done correctly, you should see one stroke of primer exit the hose, then almost pure concrete. It should't be mixed for 3 or 4 strokes.
