2.Make sure the media used is dry to avoid clogging the Media Metering Valve (18), Media Manifold (19), or Material Hose (25). (See Figure G.)

3. WARNING! Always wear ANSI-approved safety impact eye glasses under a full face shield, a respirator, and heavy duty work gloves when operating the Pressure Blasting System. Also, wear heavy duty work boots, long trousers, and long sleeve shirt.

4.Turn the Air Input Valve (14) to the “OFF” (horizontal) position. (See Figure G.)

5.Check the Pressure Gauge (5) to make sure it reads “0” pressure.

(See Figure G.)

6.Pour the media into the Tank (3), making sure to pour enough into the Tank to do the job at hand. NOTE: If this is a large job, fill the Tank only 3/4 full and reload as needed to finish the job. (See Figure G.)

7.IMPORTANT TIP: If the humidity is 90 to 100%, the Water Trap (12) will not be able to trap all of the moisture in a 3/4 full Tank (3). It is recommended to reduce the amount of media, load more frequently, and empty the Water Trap more often. This will reduce the possibility of clogging the bottom of the Tank or the line. (See Figure G.)

8.Depending on the size (diameter) of the media, install the proper size Nozzle (42 or 42A) onto the Sandblasting Gun. To do so, unscrew and remove the Nozzle
