Basic Operation
This section details the correct order of operations
for using the Model G0707.
To use the blast cabinet:
1. Prepare the cabinet and workpiece for blasting
as discussed in
Preparation on Page 20.
2. PUT ON safety goggles and a respirator.
3. Select and load the blasting media through a
cabinet door. Avoid using media that contains
free silica, as this is a leading cause of
silicosis
. Refer to Page 25 for media types.
Note: Loading only enough media for the job
at hand will help you prevent over-using or
having to screen excess media. Typically use
just enough media to cover the suction tube
opening by 6".
4. Install the correct blast tip in the position
shown in
Figure 19. For lower air pressure
systems, the 6mm tip is the best choice.
Refer to
Page 25 for air pressure and media
options.

5. Empty the dust collector canister periodically
during long blasting operations and after every
use. Every five hours of blasting operations,
clean the canister filter using compressed air
(see
Figure 20).
6. Empty the applicable water separators and
connect the blasting cabinet to the power and
air supply.
7. Turn the regulator knob to adjust the air
pressure to the desired setting. Typically this
is a trial-and-error process, but a good range
to start is between 60 and 80 PSI.
8. Place the properly-cleaned workpiece into the
blast cabinet, close the doors, then move the
latches until they are completely locked (see
Figure 21).

Note: It is very important to maintain
concentricity of the tip orifice as it wears. To
do this you must rotate the media blasting tip

make an inconsistent media spray pattern. As
a result, surfaces can be left with streaking or
tear-out. Replace any tip that has worn
