ABRASIVE BLASTING (RED VALVES)
Always wear your blast hood, NIOSH approved respiratory protection, ANSI-approved safety glasses and heavy duty canvas gloves when operating the
abrasive blaster.
Before operating your abrasive blaster, inspect each connection, double checking to make sure that all are tight and properly sealed.
THIS MACHINE IS NOT INTENDED FOR USE WITH SILICA BASED ABRASIVES. SILICA BASED ABRASIVES HAVE BEEN LINKED TO SEVERE
RESPIRATORY DISEASE.
LOADING ABRASIVE
1.
Before opening tank, be sure that it is not pressurized and the air gauge reads "0".
2.
To release the pressure from the Tank, press Blast Discharge Nozzle until air stops.
3.
Check to make sure the abrasive is dry and clean so that it does not clog the unit. Use 80 grit or fi ner material.
4.
Close the brass Air Supply Valve by turning it to the vertical position.
5.
Remove the Filler Cap.
6.
Using the Funnel, pour the selected abrasive media into the tank. Do not fi ll the tank more than 3/4 full. If humidity in your region is 90% or more, only fi ll the tank half full
and check the water trap more frequently.
7.
Close the Filler Cap securely, assuring o-ring is in place.
8.
To avoid damage, it is advisable to have your compressor located in another room away from damaging debris.
TO START ABRASIVE BLASTING
Start with all valves in the closed position. Following the instructions below will help prevent the formation of clogs in the abrasive hose, outlet manifold and the Blast Discharge
Nozzle.
1.
Connect air compressor to the Inlet Connector.
2.
Open Air Supply Valve.
3.
Open Throttling Valve.
4.
Check for leaks at the Filler Cap and along all hoses and fi ttings as the system pressurizes. If leaks are observed, release the pressure from the tank and repair immedi-
ately.
5.
Point Blast Discharge Nozzle in a safe direction away from people, pets or anything around you that may be harmed by direct or indirect abrasive spray.
6.
Press and hold Blast Discharge Nozzle until air is fl owing through the nozzle.
7.
With the Blast Discharge Nozzle open, slowly open the Abrasive Control Valve until abrasive material begins to fl ow out of the Blast Discharge Nozzle.
8.
Abrasive Flow Adjustment as follows:
conditions.
-
Adjust air pressure with the Throttling Valve. The Throttling Valve controls the velocity of material flow.
-
Adjust abrasive flow with Abrasive Control Valve. The Abrasive Control Valve controls the amount of abrasive in the stream.
-
Watch for abrasive clogging. Release pressure from the tank if necessary and replace the abrasive with drier or cleaner abrasive.
9.
Begin blasting.
TO STOP BLASTING
1.
While continuing to press and hold the Blast Discharge Nozzle, turn the Abrasive Control Valve to the closed position (this is to prevent any clogging.)
2.
When you notice only air (no abrasive) is coming out of the Blast Discharge Nozzle, you can stop the air fl ow by releasing the trigger. This ensures a clean and clog-free
manifold, hose, and safety trigger.

NOTE:
The Abrasive Flow is a fi nely tuned combination of two adjustments which can vary with different media and atmospheric
