Secure loose work pieces using a 3.
vise or clamps (not included) to pre-
vent movement while working.
There must not be hazardous ob-4.
jects (such as utility lines or foreign
objects) nearby that will present a
hazard while working.
There will be considerable excess 5.
blasting medium left in the work area.
Contain it and clean it up.
General Operating Instructions
WARNING: Do not hold the work 1.
piece in hand while blasting it. You
may seriously injure yourself.
If possible, place the work piece 2.
inside a sandblast cabinet. Other-
wise, isolate the work piece 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.
Turn the Air Input ON OFF Valve (4) 3.
at the Air Pressure Regulator (5) to
the ON position.
Grip the Media Outlet Hose (19) and 4.
Ceramic Nozzle (21) rmly. Turn the
Media Release ON OFF Valve (18) of
the Media Regulator Assembly (15) to
the ON position to release the media.
NOTE: The ow rate of the media
may be irregular when rst started.
Provided the media is dry, the ow
rate will become normal in approxi-
mately one minute.
Spray the abrasive media onto the 5.
work material, moving the gun from
side to side.
Adjust Media Flow Control Knob (16) 6.
to increase or decrease the media
ow rate.
Adjust the Air Pressure Regulator (5) 7.
to trim the total air ow and pressure
at the Ceramic Nozzle (21). Do not
set the pressure higher than 100 PSI.
If the Soda Blaster requires more 8.
force to accomplish the task, verify
that the Soda Blaster receives
sufcient, unobstructed airow (CFM)
and increase the pressure (PSI)
output of the regulator up to the
maximum air pressure rating of this
Soda Blaster.
CAUTION! TO PREVENT SODA
BLASTER AND ACCESSORY
FAILURE, RESULTING IN INJURY:
Do not exceed the Soda Blaster’s
maximum air pressure rating.
If the Soda Blaster still does not have
sufcient force at maximum pressure
and sufcient airow, then a larger
Soda Blaster may be required.
If excessive air pressure is used, 9.
or the Media Regulator Assembly
(15) becomes clogged, the Safety
Valve (17) may open, releasing air
pressure. Shut OFF the Air Input
ON OFF Valve (4). Adjust the Air
Pressure Regulator (5) to below
100 PSI. Press the stem of the
Safety Valve (17) back in to reset
the valve. Turn the Air Input ON OFF
Valve (4) back on. If the problem
happens again, detach the air supply
and clean out the Media Regulator
Assembly (15) and Media Outlet
Hose (19).
To prevent accidents, turn off the 10.
Soda Blaster, detach the air sup-
ply, safely discharge any residual air
