After filling the pressure pot with media, you need to install a suitable ceramic nozzle on the gun or wand. For operators starting with walnut shells, it is recommended to use a 1/8″ nozzle on the gun, and 3/32″ for soft media. 

Put on your protective gear like protective gloves, goggles, blast hood, etc, to prevent damage to the skin.

Switch on your compressor and set the pressure at 35 pounds per square inch. Ensure the gun is tested on a piece of scrap wood. 

Most times, the result of the test may reveal some effect, in this case, fill the tank with more sandblasting media and start the test again. If it doesn’t work, you might need to increase the output pressure to 10-psi and test again.
