air Supply Setup
tO preVent SeriOuS inJury FrOM eXpLOSiOn:
use only clean, dry, regulated, compressed air to power this tool.
Do not use oxygen, carbon dioxide, combustible gases, or any other bottled gas
as a power source for this tool.
1. Incorporate a filter, regulator with pressure gauge,
in‑line shutoff valve, and quick coupler for best
service, as shown on Figure A on page 7 and
Figure B on page 9. an in-line shutoff ball
valve is an important safety device because
it controls the air supply even if the air hose
is ruptured. the shutoff valve should be a
ball valve because it can be closed quickly.
note: Do not use an automatic oiler system or
add oil to airline. The oil will contaminate the
material being propelled, ruining the final result.
2. Attach an air hose to the compressor's air outlet.
Connect the air hose to the air inlet of the tool.
Other components, such as a coupler plug
and quick coupler, will make operation
more efficient, but are not required.
note: A 3/8" air hose is recommended.
3. To attach an air hose ‑ 1/4" ‑ 18 NPT (not
included) to the Blast Gun, wrap approximately
3" of pipe thread sealer tape (not included)
around the male threads at the end of the
air hose. Then, firmly tighten the air hose
onto the Air Inlet of the Blaster Gun.

FrOM acciDentaL OperatiOn:
Do not install a female quick coupler on the tool.
Such a coupler contains an air valve that will
allow the air tool to retain pressure and operate
accidentally after the air supply is disconnected.

For technical questions, please call 1-888-866-5797.
note: Air flow, and therefore tool performance,
can be hindered by undersized air supply components.
4. The air hose must be long enough to reach
the work area with enough extra length to
allow free movement while working.
5. Close the in‑line shutoff valve between
the compressor and the tool.
6. Turn on the air compressor according to
the manufacturer's directions and allow it
to build up pressure until it cycles off.
7. Open the in‑line shutoff valve.
8. Adjust the air compressor's output regulator
so that the air output is enough to properly
power the tool, but the output will not exceed
the tool's maximum air pressure at any time.
Adjust the pressure gradually, while checking the
air output gauge to set the right pressure range.
9. Inspect the air connections for leaks.
Repair any leaks found.
10. If the tool will not be used at this time, turn off and
detach the air supply and safely discharge any
residual air pressure to prevent accidental operation.
note: Residual air pressure should not be present
after the tool is disconnected from the air supply.
However, it is a good safety measure to attempt to
discharge the tool in a safe fashion after disconnecting
to ensure that the tool is disconnected and not powered.
