5. Set-Up and Operation
5.1 Set-Up
An air filter is recommended in the air supply to remove condensed moisture from the air
line.
Connect POWER GUN to a 25mm (1") ID air hose. An isolation valve is required at the air
source to enable depressurization.
Secure all compressed-air supply hose connections with safety lock pins to prevent
accidental disconnection.
5.2 Operation
Use the pointed end of the lance to pierce the bag of abrasive. Insert the lance into the
abrasive. The upper (air-intake) holes must remain open, and outside of the abrasive.
Pressurize the air supply line.
Put on the appropriate protective gear, including supplied-air respirator, abrasive resistant
clothing, leather gloves, and hearing protection as required.
Hold the gun approximately 150mm from the blast surface, and squeeze the trigger lever.
Adjust the stand off distance and angle for optimum performance.
5.3 Shutdown
When finished blasting, remove the lance from the abrasive and shake abrasive from the
material hose. If conditions are safe to do so, pull the trigger to further empty the hose.
When finished blasting, and after cleanup is completed, remove the respirator outside the
blasting area, where the air is safe to breathe.
Depressurize the air supply line and shutdown the compressor.
