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.)

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.

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.)

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.)

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
