- If the switch is functioning, make sure the yellow tubing inside the control box is properly connected and is clear of obstructions.
- If the tubing is clean and connected, replace the 4-way solenoid valve.
- Fill the water tank with fresh water only, then open the inlet ball valve.
- Close the rinse ball valve and abrasive ball valve. Close the water dose meter if equipped.
- Turn the selector valve to OFF.
- Disengage the Emergency Stop.
- The water pump will not work unless the Emergency Stop is disengaged.
- Align the pop-up handle with the pin slot, and then firmly push and turn the handle 90 degrees after the pin is below the bracket slot. Proper engagement of the pin will hold the pop-up down until it is released.
- Open the pot dump valve.
- Add 30 litres (10 gallons) of fresh water to the pot. Add abrasive material (see technical specifications in manual for capacity information).
- Close the pot dump valve.
- Use a garden hose or the rinse hose to wash the abrasive into the pot and clear any abrasive from the pop-up and gasket,
- Make sure water is above the pop-up seal and the pop-up seal is closed. Failure to do so before pressurising the pot can result in serious injury to the operator.
- When the water level is above the pop-up gasket, rotate the handle to release the pop-up pin.

- Open the abrasive ball valve.
- The optimal set point of the abrasive metering valve and corresponding MediaTrak CPM value varies significantly depending on application and user desired performance. The General Application Guides in the manual describe the generally accepted range of CPM set points based on the substrate and blast pressure set point. The grey highlighted area illustrates the typical range of blast pressure set points and their corresponding CPM set points for that substrate.
- To find the recommended CPM set point, select the table that most closely matches the substrate that is to be blasted. Determine the blast pressure set point based on the media that is being used, and the desired surface profile to be achieved. Then, use the corresponding lines on the chart to select the appropriate CPM set point.
- For inexperienced users, select a blast pressure near the low end of the highlighted range. Increase blast pressure and CPM until the desired profile and removal rate are achieved.
