dark work areas invite accidents.
5. Keep children away. All children should be kept
away from the work area. Never let a child
handle a tool without strict adult supervision.
6. Do not operate this tool if under the influence of
alcohol or drugs. Read warning labels on
prescriptions to determine if your judgment or
reflexes are impaired while taking drugs. If there is
any doubt, do not attempt to operate.
7. Use safety equipment. Eye protection should be
worn at all times when operating this tool. Use
ANSI approved safety glasses. Everyday eye-
glasses are NOT safety glasses. Dust mask, non-
skid safety shoes, hard hat, or hearing protection
should be used in appropriate conditions.
8. Wear proper apparel. Loose clothing, gloves,
neckties, rings, bracelets, or other jewelry may
present a potential hazard when operating this
tool. Please keep all apparel clear of the tool.
9. Don’t overreach. Keep proper footing and
balance at all times when operating this product.
10. Always disconnect the tool from air supply and
release pressure from the tank before making any
adjustments, storing, servicing, or changing
accessories. Such preventative safety measures
reduce the risk of starting the tool accidentally.
11. Use clamps or other practical means to secure
and support the work piece to a stable platform.
Holding the work by hand or against your body
may lead to a loss of control.
12. Do not force tool. Use the correct tool for your
application. The correct tool will do the job better
and safer at the rate for which it was designed.
13. Check for damage. Check your tool regularly. If
part of the tool is damaged it should be carefully
inspected to make sure that it can perform its’
intended function correctly. If in doubt, the part
should be repaired. Refer all servicing to a
qualified technician. Consult your dealer for advice.
14. Keep away from flammables. Do not attempt to
operate this tool near flammable materials or
combustibles. Failure to comply may cause
serious injury or death.
15. Always check to make sure that the trigger is not
on before connecting blaster to air supply. Tool

while unattended or not in use.
19. Make sure all equipment is rated to the
appropriate capacity. Make sure regulator is set
at no higher than 125 psi.
20. Periodically check the abrasive medium delivery
equipment. Valves, hoses and nozzles that carry
the abrasive medium after it leaves the pressure
tank are subjected to the abrasive blasting action
so will wear out more quickly than other
components.
21. Release the air pressure in the tank before
opening. See "Releasing Pressure from the
Tank" section. Make sure pressure gauge reads
“0” before opening the tank. Do not attempt any
maintenance on the abrasive blaster until the
pressure gauge reads “0”, and it has been
disconnected from air supply.
22. Maintain correct air pressure whenever working.
Do not allow pressure to exceed 125 psi. If the
safety valve does not release excess air
pressure, stop all work and release pressure
from the tank (see "Releasing Pressure from the
Tank" section).

OPERATION
! Warning: Always wear your hood, dust mask
and heavy duty canvas gloves when operating
the abrasive blaster.
! Warning: Before operating your abrasive blaster,
inspect each connection, double checking to
make sure that all are tight and properly sealed.
! WARNING: THIS MACHINE IS NOT
INTENDED FOR USE WITH SILICA
BASED ABRASIVES. SILICA BASED
ABRASIVES HAVE BEEN LINKED TO
SEVERE RESPIRATORY DISEASE.
ALWAYS USE SILICA SUBSTITUTES
(SUCH AS - GLASS BEAD - RED
GARNET) WHEN ABRASIVE BLASTING!
Loading Abrasive
1. Check to make sure the abrasive is dry and
clean so that it does not clog the unit.
2. Close the brass Air Supply Valve (19) by turning
it to the vertical position.
3. To release the pressure from the Tank, press
Safety Trigger until air stops.
4. Make sure the Pressure Gauge (16) reads “0”.
5. Remove the Filler Cap (13).
6. Using the Funnel (27), pour the selected abrasive
media into the tank (1). Do not fill the tank more
than 3/4 full. If humidity in your region is 90% or
more, only fill the tank half full and check the
water trap (18) more frequently.
7. Close the Filler Cap securely, assuring O-ring is
in place.
Note: Place your air compressor in another room to
prevent damage to it.
To Start Abrasive Blasting
Note: 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 safety trigger.
1. Connect air compressor to the Inlet Connector (20).
2. Start compressor and open Air Supply Valve (19).
3. Open Throttling Valve (19A).
4. Check for leaks at the Filler Cap and along all
hoses and fittings as the system pressurizes. If
leaks are observed, release the pressure from
the tank and repair immediately.
5. Point Safety Trigger in a safe direction away from
people, pets or anything around you that may be
damaged by direct or indirect abrasive spray.
6. Press and hold Safety Trigger until air is flowing
through the trigger.

7. With the Safety Trigger open, slowly open the
Abrasive Control Valve (19B) until abrasive
material begins to flow out of the Safety Trigger.
8. Adjust the Abrasive Control Valve (19B) until the
desired amount of abrasive material is flowing
through the Safety Trigger.
9. Begin blasting.
To Stop Blasting
1. While continuing to press and hold the Safety
Trigger, turn the Abrasive Control Valve (19B) to
the closed position (this is to prevent any
clogging.)
2. When you notice only air (no abrasive) is
coming out of the Safety Trigger, you can stop
the air flow by releasing the trigger. By doing
this you are ensuring a clean and clog-free
manifold, hose, and safety trigger.
Releasing Pressure from the Tank
1. When finished blasting, point Safety Trigger in a
safe direction away from people, pets or
anything around you that may be damaged by
direct or indirect abrasive spray.
2. Press and hold the Safety Trigger to expel any
remaining abrasive material from the Abrasive
Hose (25).
3. Close the Abrasive Control Valve (19B).
4. Release pressure on the Safety Trigger.
5. Close the Throttling Valve (19A) and the Air
Supply Valve (19).
6. Disconnect air supply hose from abrasive blaster.
7. Press the Safety Trigger until air stops flowing
and Pressure Gauge (16) reads “0".
MAINTENANCE
1. Keep your abrasive blaster clean, and protect it
from damage.
2. Release pressure from the tank after each use.
3. When initially pressurizing, check for leaks at
the tank top and at all hoses and fittings.
Leaking joints may be repaired by replacing
worn or damaged parts and Teflon tape at joints.
4. Check for worn abrasive hose and fittings. The
Abrasive Control Valve, manifold, and all parts after
the abrasive is ejected from the tank are subject to
rapid wear due to the flow of abrasive. Watch
especially for leaks, blistering, bulging or thinness
of the hose. Replace any parts which appear worn.
ABRASIVE SELECTION
The kind of abrasive you choose will greatly influence
the amount of time needed to clean a given surface
area. Abrasive materials include garnet, glass beads
and others. For best results, use 80 grit abrasive or
finer. Do not exceed 80 grit media size.
Abrasive Media Quick Reference Guide
Red Garnet
Hardness: 8
Red Garnet is good for general metal usage.
Ideal for general rust, paint and scale removal
from metal parts.
Glass Bead
Hardness: 6
Perfect for light deburring or applying satin-like
finishes on parts. Round shape of glass bead
keeps it from cutting into work surfaces; instead
the surface is pounded or “peened.”
• Make sure that the abrasive you use is
thoroughly dry. Damp abrasive can cause
clogging of your abrasive blaster.
• While you may reuse abrasive, remember that
abrasive does wear out. After use, abrasive
becomes smoother and rounder, thus reducing
abrasive effectiveness.
• Reusing abrasive may also cause clogging due
to debris contained in the mixture from prior use.
Abrasive Flow Adjustment
• Choose a larger nozzle for a broader spray
pattern. Choose a smaller nozzle for more
focused abrasive blasting.
• Adjust air pressure with the Brass Throttling
Valve (19A). Adjust abrasive flow with Abrasive
Control Valve (19B).
• Watch for abrasive clogging. Release pressure
from the tank if necessary and replace the
abrasive with drier or cleaner abrasive.
Safety and Health Considerations
! WARNING: THIS MACHINE IS NOT
INTENDED FOR USE WITH SILICA
BASED ABRASIVES. SILICA BASED
ABRASIVES HAVE BEEN LINKED TO
SEVERE RESPIRATORY DISEASE.
ALWAYS USE SILICA SUBSTITUTES
(SUCH AS - GLASS BEAD OR RED

• Before opening tank make sure that it is not
pressurized. Be sure that the gauge reads “0”.
If the gauge does not read “0”, release pressure
from the tank (see “Releasing Pressure from the
Tank” section).
• Disconnect the compressor before opening tank.
• Protect yourself and those around you from
“over-spray”. Remember that your portable
abrasive blaster is shooting a powerful spray of
abrasive material. Do not point it at yourself or
anyone around you.

• Wear protective clothing including hood (28),
safety eye covering, and heavy gloves when
using this abrasive blaster.
• Wear a filter or mask over your mouth when
using this tool. You will create a cloud of abrasive
material and debris which is dangerous to inhale.
• Remove, cover or protect anything around you that
might be damaged from direct or indirect contact
with the abrasive spray or particles. Nothing
subject to contamination damage or with a fine
surface should be near your abrasive blaster.
Caution
Pay particular attention to the Abrasive Hose (25),
the Abrasive Control Valve (19B), and the Nozzles
(35) as they will wear out much more quickly than
the other pieces.
The Abrasive Hose needs to be replaced
immediately if its side walls develop leaks or show
blisters in the surface. Do not use if any of these
problems are present.
