8. Abrasive Flow Adjustment as follows: Note: The Abrasive Flow is a fi nely tuned combination
of two adjustments which can vary with different media and atmospheric conditions.
• Adjust air pressure with the Throttling Valve. The Throttling Valve controls the velocity of
material fl ow.
• Adjust abrasive fl ow with Abrasive Control Valve. The Abrasive Control Valve controls
the amount of abrasive in the stream.
• Watch for abrasive clogging. Release pressure from the tank if necessary and replace
the abrasive with drier or cleaner abrasive.
9. Begin blasting.
To Stop Blasting
1. While continuing to press and hold the Blast Discharge Nozzle, turn the Abrasive Control Valve
to the closed position (this is to prevent any clogging.)
2. When you notice only air (no abrasive) is coming out of the Blast Discharge Nozzle, you can
stop the air fl ow by releasing the trigger. This ensures a clean and clog-free manifold, hose,
and safety trigger.
Releasing Pressure From The Tank
1. When you are fi nished blasting, point Blast Discharge Nozzle in a safe direction away from
people, pets or anything around you that may be harmed by direct or indirect abrasive spray.
2. Press and hold the Blast Discharge Nozzle to expel any remaining abrasive material from
the Abrasive Hose.
3. Close the Abrasive Control Valve.
4. Release pressure on the Blast Discharge Nozzle.
5. Close the Throttling Valve and the Air Supply Valve.
6. Disconnect air supply hose from abrasive blaster.
7. Press the Blast Discharge Nozzle until air stops fl owing and Pressure Gauge reads "0".
Pay particular attention to the Abrasive Hose, the Abrasive Control Valve, and the
Nozzles as they will wear out much more quickly than the other pieces.
The Abrasive Hose needs to be replaced immediately if its side walls develop leaks or show blisters
in the surface. Do not use if any of these problems are present.
