To Attach A Quick Connector:
1. Prior to use, the Pressure Blasting System requires the attachment of a Quick
Connector (not included) to its Air Input Valve (14). To do so, make sure the
screen Air Filter within the Valve Body is properly seated in the Valve Body. Wrap
approximately 3” of Pipe Thread Seal Tape (47) around the male threads of the
Quick Connector. Then, firmly tighten the Quick Connector into the Valve Body.
(See Figure F.)

OPERATING INSTRUCTIONS
Abrasive Selection:
1. The type of media chosen will greatly influence the amount of time needed to
clean a particular surface area.
2. Sandblasting media include silicon carbide, glass bead, walnut shell, brass bead,
and alumina.
3. If you decide to reuse media, remember, it does wear out. The sharp edges
become rounder and are less effective. At that point you should replace the tank
of media you are using.
To Load Media Into The Tank:
1. WARNING! Never service the Pressure Blasting System or disassemble
with the air hose attached. Always release any built-up air even after
disconnecting the hose.
