4 MXS3000 Common Abrasive Media Crushed glass is very aggressive. Used for economical, general clean-up. Plastic is available in a variety of sizes and materials (urea, acrylic, polyester, and melamine). These materials are ideal for application such as auto restoration to deliver a high stripping rate without damaging or warping the substrate material. Brown aluminum oxide is a widely used abrasive media. This media produces a textured surface, good for repairing surfaces for recoating. It is excellent for removing heavy foreign materials, deburring, and etching glass and stone. It is a fast-cutting media that can be reused many times. White aluminum oxide can be used in the same applications as the brown aluminum oxide, but white aluminum oxide is considered to be a clean media, used in high performance processes where contamination of metal oxide must be kept to a minimum. Aluminum / glass mixtures provides a combination of glass bead finishing and aluminum oxide cleaning. It provides a brighter finish than single abrasives, and it is good for removing rust and machine marks on metal. Silicon carbide is the hardest abrasive material available. It is fast cutting and can be reused many times. It is high in initial cost, but removes material quickly to reduce blasting time.

When humidity is high or when a compressor is in continuous use for an extended period of time, moisture will collect in the tank. When blasting, this water will be carried from the tank through the hose and will be mixed with the abrasive media. IMPORTANT: THIS MIXING OF WATER AND ABRASIVE MATERIAL WILL CLOG THE SYSTEM. THE BLASTER WILL NOT OPERATE. A compressed air dryer and/or water separator will help eliminate this problem. 5 Operating Instructions Troubleshooting Chart Symptom Possible Cause(s) Corrective Action Low or no air pressure at tool 1. Regulator set incorrectly 1. Reset regulator 2. Pinched hose 2. Straighten hose 3. Dirty compressor filter 3. Clean or replace filter Material not blasting from gun 1. Clogged material hose 1. Lower the pressure below 40 psi. Firmly hold the gun tip flat against the ground and pull the trigger to force the material back out of the material hose 2. Buildup around jet 2. Remove nozzle and clean around jet 3. Damp or heavy material 3. Replace with dry abrasive. (Damp material can be dried and reused) 4. Water in air supply 4. Drain compressor tank and install water separator, See “Moisture in Compressed Air” box Gun will not shut off - trigger stuck Damaged o-rings in air valve Remove and replace o-rings Sputtering - low vacuum 1. Worn jet and/or nozzle 1. Replace jet and/or nozzle 2. Abrasive buildup around jet/nozzle 2. Remove nozzle and jet and clean. Make sure the threads are clean before re-assembling Sputtering - air/abrasive leaks at 1. Loose nozzle or jet 1. Tighten nozzle or jet nozzle/jet area 2. Damaged o-ring 2. Replace o-ring Sputtering - vacuum leak 1. Loose material hose 1. Tighten material hose 2. Damaged o-ring 2.
