Tips for Better Operation of your Abrasive Blaster
Abrasive Selection:
1.
The type of media chosen will greatly influence the amount of time needed to
clean a particular surface area.
2.
Abrasive blasting media include glass or metal beads, aluminum oxide or
walnut shells.
3.
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.
Here is a representative list of media options:
Silicon Carbide is the hardest blasting media available. Silicon carbide has a very
fast cutting speed and can be recycled and re-used many more times than most
media other than steel shot. The hardness of silicon carbide delivers a much
shorter blast time compared to other blast media. However, Silicone Carbide is not
recommended due to the danger of Silicosis disease.
Aluminum Oxide can be re-used many times for grit blasting. It is a sharp, longlasting abrasive sandblasting cutting media which is harder than most common dry
abrasive blast media. It will cut even the hardest metals and surfaces. It is available
in a variety of grit sizes. Aluminum Oxide has limited re-use life because the
individual grains can shatter during blasting.
Steel Grit contains angular carbon steel which is effective for fast removal of paint,
rust and scale from metals. Steel Grit is softer than Aluminum Oxide and is less
likely to fracture during blasting. It leaves an etched surface which is excellent for
adhesion of paints and coatings.
Crushed Glass Grit is a silica-free consumable abrasive. It normally cannot be
used more than once because it powders during blasting. Crushed Glass Grit
produces a whiter, cleaner finish than mineral or steel abrasives.
Bead Blasting produces a distinctive pebbled surface on metals. Bead blasted
finishes are softer and brighter than finishes produced by sharp edged abrasives.
Glass beads and steel shot are frequently used bead blasting media.
Glass Beads are silica-free and can be used for shot blasting, peening, honing,
cleaning and light deburring. Glass Beads can usually be recycled up to 30 times.
Steel Shot can be used repeatedly and produce very little media dust during the
blasting process. Steel shot will produce a clean, smooth and polished finish. Steel
shot blasting will also work-harden metals, creating a harder surface layer.

For technical questions please call 1-800-444-3353 Page 9
Plastic Abrasives are ideal for sheet metal applications such as auto restoration.
They can strip paint quickly without damaging or warping the substrate.
Walnut Shells are an organic media which has an angular shape. They are
effective for paint stripping of sheet metal and plastic, and are also useful for
polishing harder metals such as steel alloys and titanium.
Corn Cob is an even softer biodegradable media which will not etch or warp the
surface being blasted. It is ideal for wood and thin metals and plastics. Corn cob is
also a useful polishing media.
Pumice is the softest of all the blasting media yet still offers excellent stripping
properties. Excellent for blasting surfaces such as soft wood to remove paint and
coatings with no impact on the substrate. Pumice is available in various grits and
can be used for polishing.
Loading Media Into The Tank:
1.
WARNING! Never service the Abrasive Blaster or disassemble with the air hose
attached. Always release any built-up air even after disconnecting the hose.
2.
Make sure the media used is dry to avoid clogging the Abrasive Hose (30) or
Blast Gun Assembly.
3.
Pour the media into the Abrasive Tank (22), 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.
4.
IMPORTANT TIP: If the humidity is 90 to 100%, it is recommended to reduce
the amount of media and load more frequently. This will reduce the possibility
of clogging the bottom of the Tank, the Abrasive Hose (30), and Blast Gun.
Operating The Abrasive Blaster:
1.
If possible, place the workpiece inside a sandblast cabinet. Otherwise, isolate
the workpiece to make sure no damage can occur to nearby walls, tools,
personal property, etc. CAUTION: Make sure spectators are completely clear
of the work area before beginning work.
2.
Connect the air compressor’s hose to the Coupler (40) on the Blast Gun Then turn
on the air compressor, and set its regulator to 115 PSI. Do not exceed 115 PSI.
3.
Grip the Blast Gun firmly with both hands.
4.
Keep the Brush Head (47) in contact with the work surface to effectively return
material through the vacuum system.
5.
Squeeze the Trigger of the Blast Gun to release the media. NOTE: The flow rate
of the media may be irregular when the Blast Gun is first started. Provided the
media is dry, the flow rate will become normal in approximately one minute.

For technical questions please call 1-800-444-3353 Page 10
6.
Adjust pressure on the Trigger of the Blast Gun to increase or decrease the
media flow rate.
7.
Adjust the air compressor’s regulator to regulate the total air flow and pressure
at the Blast Gun (no more than 115 PSI).
8.
Move the Blast Gun in a circular or right to left motion until you have achieved
the desired appearance (finish) on the workpiece.
9.
Periodically, check the water filter on the air compressor system for excessive
water buildup. If necessary, discontinue work while the filter is drained.
10. When the abrasive blasting job is completed, release pressure on the Trigger
of the Blast Gun. Turn off the air compressor. Then squeeze the Trigger of the
Blast Gun again to release any remaining compressed air in the system.
11. Unplug the Power Cord.
12. Empty the Abrasive Tank (22) of any remaining media. Remove and clean the
Debris Filter (25) from the bottom of the Abrasive Tank (22).
INSPECTION, MAINTENANCE, AND CLEANING
1.
WARNING! Prior to performing any inspection, maintenance, or cleaning of the
Abrasive Blaster, turn off the air compressor. Squeeze the Trigger of the Blast
Gun to release any remaining compressed air in the system. Then,
disconnect the compressor’s air hose from the Blast Gun. Unplug the Power
Cord of the Vacuum Assembly.
2.
Before each use, inspect the general condition of the Abrasive Blaster and its
accessories. Check for loose screws, misalignment or binding of moving
parts, cracked or broken parts, damaged air hoses, and any other condition
that may affect safe operation. If abnormal noise or vibration occurs, have the
problem corrected before further use. Do not use damaged equipment.
3.
Before, during, and after use: Periodically, check the water filter in the air
compressor system for excessive water buildup. If necessary, discontinue
working and drain the water filter.
4.
Periodically check the Filter (15). Replace when dirty.
5.
To clean the exterior of the Abrasive Blaster, wipe with a clean, damp cloth
using a mild detergent or mild solvent.
6.
When storing, always store the Abrasive Blaster in a clean, dry, safe location
out of reach of children and other unauthorized people.
