Air Supply
TO PREVENT
EXPLOSION:
Use only clean, dry, regulated,
compressed air to power this
Soda Blaster. Do not use
oxygen, carbon dioxide,
combustible gases, or any
other bottled gas as a power
source for this Soda Blaster.
1. Incorporate an in-line lter, shut-off
valve and regulator with pressure
gauge for best service, as shown in
the diagram above. An in-line shut-
off valve is an important safety
device because it controls the air
supply even if the air hose is rup-
tured.
Attach an air hose to the compres-2. sor’s air outlet. Connect the air hose
to the Male Coupler of the Soda

Blaster. Note: Use of quick coupler
is recommended, but not mandatory.
Note: Air ow, and therefore Soda Blaster
performance, can be hindered by
undersized air supply components.
The air hose must be long enough3. to reach the work area with enough
extra length to allow free movement
while working.
Close the in-line safety valve be-4. tween the compressor and the Soda
Blaster.
Turn on the air compressor according5. to the manufacturer’s directions and
allow it to build up pressure until it
cycles off.
Adjust the air compressor’s output 6. regulator so that the air output is
enough to properly power the Soda
Blaster, but the output will not exceed
the Soda Blaster’s maximum air pres-
sure at any time. Adjust the pres-
sure gradually, while checking the air
output gauge to set the right pressure
range. To do so, close Air Input ON/
OFF Valve (4). Pull out on the Quick
Disconnect Safety Valve (7) to stabi-
lize air pressure in the Storage Tank
(1).
If the Soda Blaster will not be used at7. this time, turn off and detach the air
supply, safely discharge any residual
air pressure, and release the throttle
and/or turn the switch to its off posi-
tion to prevent accidental operation.
Note: Residual air pressure should not be
present after the Soda Blaster is dis-
connected from the air supply. How-
ever, it is a good safety measure to
attempt to discharge the Soda Blaster
in a safe fashion after disconnecting
to ensure that the Soda Blaster is
disconnected and unpowered.

ther repair or replace the product at our election or we may elect to refund the purchase

paired products at our expense, but if we determine there is no defect, or that the defect
resulted from causes not within the scope of our warranty, then you must bear the cost
of returning the product.
This warranty gives you specic legal rights and you may also have other rights
which vary from state to state.
