respirator, safety impact eye glasses, and a full face shield. Avoid skin  
exposure. Proper ventilation in the work area is required. Read and  
understand the ten recommended measures below to reduce crystalline silica  
exposure in the workplace and prevent silicosisand silicosis related injuries and  
deaths.  
The following ten measures are recommended to reduce crystalline silica  
exposures in the workplace and prevent silicosis and silicosis related  
injuries and deaths:  
1. Prohibit silica sand (or other substances containing more than 1% crystalline  
silica) as an abrasive blasting material and substitute less hazardous  
materials.  
2. Conduct air monitoring to measure worker exposures.  
3. Use containment methods such as blast-cleaning machines and cabinets to  
control the hazard and protect adjacent workers from exposure.  
4. Practice good personal hygiene to avoid unnecessary exposure to silica dust.  
5. Wear washable or disposable protective clothes at the worksite. Shower, and  
change into clean clothes before leaving the worksite to prevent contamination  
of cars, homes, and other work areas.

The type of media chosen will greatly influence the amount of time needed to  
clean a particular surface area.  
Sandblasting media include silicon carbide, glass bead, walnut shell, brass bead,  
and alumina.  
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.

3.  
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.  
4.  
5.  
Turn the Air Input Valve (14) to the “OFF” (horizontal) position. (See Figure G.)  
Check the Pressure Gauge (5) to make sure it reads “0” pressure.  
(See Figure G.)  
6.  
7.  
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.)  
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
