Assembly
1. Attach material hose to the pick-up
tube. Place pick-up tube in bag of
medium. (See Figure 4).
2. Attach the air compressor hose to
the air inlet (1/4"NPT(F)) at the
bottom of the gun handle. An
optional quick coupler and
connector can be used to attach the
hose to the gun.
Type of
Abrasive
(Sieve/Size)
Sand
(20-40)
Sand
(50-100)
Aluminum oxide
Corn cob meal
Walnut or pecan
shells (ground)
Plastic beads
NOTE: Abrasive media that has not been cleaned and screened could contain material that will clog the gun nozzle and should be avoided.
Moisture in compressed air will form into droplets as the air comes from the compressor pump. 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 using a sandblast gun, this water will be carried
from the tank through the hose and out of the gun as droplets mixed with the material being sprayed.
IMPORTANT: THIS CONDENSATION WILL CAKE THE SAND AND CLOG THE SANDBLASTING GUN. A CLOGGED GUN WILL NOT OPERATE.
A compressed air dryer and/or air line filter will help eliminate this moisture.
Figure 4
Operation
1. Locate the compressor as far away as
possible from the sandblasting area
to minimize the dust in the
compressor intake.
2. The air supply must be clean and
free of moisture and oil.
3. Use a compressor that can supply
enough air (See Specifications). A
compressor too small will cause air
pressure to drop and the sandblaster
will not operate satisfactorily.
4. Always trial test the sandblaster to
make sure the job is done without
damage by testing on a hidden
surface.
Application
General purpose use. Removing light rust and paint from metal, wood or other surfaces; wood
finishing; metal cleaning; glass and stone etching; hole drilling in glass, brick or cement block;
light stone cleaning; exterior automotive parts cleaning and water deposit removal
Used for a fine polish finish or antique wood finish, brass and silver polishing, automotive parts
cleaning and polishing, sheet metal surface polishing, and fine glass etching
Heavy rust removal and rough surface paint removal
Wood and glass cleaning (fine)
Wood and glass cleaning (coarse)
Removal of flash, burrs and paint from metal or glass without abrading work
MOISTURE IN COMPRESSED AIR

5. Always filter (screen) the abrasive
material to remove any caked
material and debris to prevent
clogging.
6. Do not try to spray thick liquids or
large grain size abrasives.
7. Use the lowest effective pressure on
soft surfaces to prevent pitting the
surface.
8. Liquids, such as soap and water, can
be sprayed for cleaning purposes on
automobiles, lawn chairs, etc.
9. With air hose and material hose
connected, and wearing proper
safety equipment, aim sandblast
gun at surface and pull trigger.
10. Whenever the nozzle is removed
and cleaned or replaced, use a
brush to clean the threads and
replace the o-ring.
