OPERATING INSTRUCTIONS
Abrasive Selection:
The type of 1. media chosen will greatly inuence the amount of time needed to
clean a particular surface area.
Abrasive blasting media include silicon carbide, glass bead, walnut shell, brass 2.
bead, and alumina.
If you decide to reuse media, remember, it does wear out. The sharp edges 3.
become rounder and are less effective. At that point you should replace the tank
of media you are using.
To Load Media And Parts Into The Blast Cabinet:
1. WARNING! Always wear ANSI-approved safety impact eye glasses under a
full face shield, a respirator, and heavy duty work gloves when operating the
Blast Cabinet. Also, wear heavy duty work boots, long trousers, and long sleeve
shirt.
WARNING! 2. Never service the Blast Cabinet or disassemble with the air
hose attached. Always release any built-up air even after disconnecting the
hose.
Make sure the media used is dry to avoid clogging the Metering Valve (13) or 3.
Blast Gun (4B). Then open a Side Door (6) and pour the media (up to 15 pounds)
over the Grate (39) within the Cabinet (22). (See Figures G and L .)
All parts to be blasted must be free of oil, grease, and moisture. Once cleaned 4.
and dried, place the parts on the Grate (39) within the Cabinet (22). Make sure
to close and securely lock the Door Latch Assembly (35). (See Figures G and L.)
Nozzle Size:
Depending on the size (diameter) of the media, install the proper size Nozzle 1.
(6mm, 7mm) into the Blast Gun (4B). To do so, unscrew and remove the Nozzle
Holding Nut (1B). Insert the desired Nozzle into the front portion of the
Blast Gun. Then screw the Nozzle Holding Nut back onto the Blast Gun to secure
the Nozzle in place. (See Assy. Diagram, page 22.)
NOTE: 2. By changing to the next larger size of Nozzle, production can increase
signicantly. Larger size Nozzles produce a larger cleaning pattern. This, how-
ever, requires a higher air pressure.
