OPERATION:
WARNING:
Always wear your hood, dust mask and heavy-duty canvas gloves when operating.
1. Close the sand metering valve (#26), pour about 25 lbs of abrasive medium into the tank.
Then close the tank filler cap (#4) securely, assuring that o-ring (#3) is in place.
2. Turn the air pressure adjuster (#9) counter-clockwise (lowest pressure) fully. With the air
compressor off, attach the connector (#8) to an air supply hose coming from the air
compressor. Tighten securely with a hose clamp.
3. Switch on power to start up the air compressor. Check for leaks at the tank filler cap (#4)
and along all hoses and fittings as pressurization begins.
4. Turn the air pressure adjuster (#9) slowly clockwise until the pressure gauge reads a
desired value.
5. Open the sand metering valve (#26) and push down the control level of the sanding gun
(#24) to an appropriate position to gain a desired sand flow.
6. To shut the unit down, close the sand metering valve (#26) and turn the air pressure
adjuster (#9) counter-clockwise until the pressure gauge reads “0 PSI”. Push down the
control level of the sanding gun (#24) to release any extra air, and to be sure that the air
supply is off.
7. If there is too much water trapped in the air pressure adjuster (#9), open the bottom
valve to drain the water.
