Too much water is coming from the nozzle in BLAST mode.

  • If possible, use at least a 40 mesh abrasive material.
  • Otherwise, decrease the CPM set point until the pattern improves.
  • Connect to a water supply.
  • Close the abrasive ball valve.
  • Turn the selector valve to OFF.
  • Open the air supply valve.
    • NOTE: The system will not work unless the air supply valve is open.
  • Fill the pot with water. Use the fill/flush valve or an external source.
  • Open the pot dump valve.
  • Add abrasive material (see Technical Specifications, in manual for capacity information).
  • Close the pot dump valve.
  • Open the fill/flush valve until water is above the pop-up seal, then pull up on the pop-up handle to pressurize the pot.
  • Close the fill/flush valve once the pot is pressurized.
    • NOTE: If using a non-pressurized water supply, fill the pot with water while in BLAST mode or use an external source.
  • Turn the selector valve to WASH until the pump stops cycling to remove air from the wash tubing.
  • Turn the selector valve to BLAST.
  • Open the abrasive metering valve 1/4 turn.
  • Check the pot pressure gauge to ensure the pot is pressurized.
  • If the pot is not pressurized, pull up on the pop-up handle while the pump is cycling.
  • Engage the blast control switch and set the blast air pressure to the desired pressure.
  • Open the abrasive ball valve.
  • While blasting, set the abrasive metering valve until the desired production is achieved.
    • NOTE: You may have to wait 1-2 minutes for the abrasive material to reach the nozzle.
  • Close the fill/flush valve.
