Operating Instructions
Operation (cont.)
16.A common wire screen placed on cabinet grating can help to prevent small items from getting lost in hopper.
Maintenance
Cleaning
The plastic door cover should be cleaned with a soft damp cloth. NEVER use solvents to clean plastic parts. They could dissolve or otherwise damage the material.
Changing the Ceramic Gun Nozzle
The blast cabinet is equipped with a ceramic nozzle that controls the flow of abrasive media as it exits the spray gun. The nozzle creates a smaller opening for the media to exit which gives a finer spray that easier to control. Replacements for the ceramic nozzle are included. To replace a nozzle, unscrew the outer metal covering of the nozzle and remove the old ceramic nozzle. Insert the new nozzle and reattach the metal cover.
Draining Abrasive Material
The blast cabinet is equipped with a drain for easy clean up of abrasive materials. The floor of the blast cabinet tapers toward the center, where the drain is located.
In order to remove blast media:
1.Make sure the air supply is disconnected before doing any draining.
2.Secure the cabinet in an elevated position that allows room for a container below the plug.
3.Place a container within 4 inches of the drain opening.
4.Pull the plug from the drain and allow media to drain from cabinet. DO NOT shake cabinet. Shaking the cabinet could cause the media to spill and create dust that could be hazardous if breathed.
You can create dust when abrasive media
is poured into or drained from the blast cabinet. Wear a mask and eye protection when draining the blasting media.
5.Any excess media can be moved toward the drain with a brush. DO NOT use the blasting gun to blow air to drain the abrasive media. Doing so can create dust that could be hazardous if breathed.
Storage
1.Turn ON / OFF switch to the OFF position.
2.Unplug power cord from outlet.
3.Disconnect the air supply from the blasting cabinet
4.Remove the abrasive media from the cabinet using the drain.
5.Store in a cool, dry place.
Service
Tool service must be performed only
by qualified repair personnel and by an AUTHORIZED SERVICE CENTER. Service or maintenance performed by unqualified personnel could result in a risk of injury.

Abrasive Blasting Media
Blasting media comes in many different grit sizes and sometimes is also rated as extra fine, fine, medium, coarse, and extra coarse. The larger the grit number, the smaller the particle size; the smaller the grit number, the larger the particle size. Glass media can come in beads, crushed, or ground. Aluminum oxide and silicon carbide can come in several colors. It is common today to find mixtures of glass and aluminum oxide.
Abrasive Media - Not Recommended
Although available, some media are not recommended for use because of mechanical and/or personal hazards.
Silica sand, a common blast media, has health risk concerns due to the silica content. Restriction on its usage is common in many states.
Beach sand (play sand) is a common and inexpensive blast media. This highly aggressive media can have debris mixed in which will cause clogging of equipment.
Steel grit produces ideal surface preparation on new coating. This media should only be used in a special blast cabinet designed for this media.
Steel shot, a round, solid particle, leaves a dimples in a surface after blasting. It is a very dense media and should only be used in a special blast cabinet designed for this media.
Common Abrasive Media
The more commonly available media and their uses are listed below.
Walnut shell is one of the most versatile organic media due to its angular, durable shape. It is still considered a soft media, but it is good to use on delicate parts. Use as an economical,
Glass beads are the most popular all- purpose media used today. Used for honing, polishing, peening, blending, finishing, removing light burrs, frosting glass, and cleaning most light materials. Common uses in the removal of paint, rust, and surface residues. Glass bead blasting generally will not change the dimensions of the item being blasted. Glass beads produce brighter finish than angular abrasives. Beads can be recycled and used many times.
