Basic Operation - Grizzly G0707 Owner's Manual

Basic Operation

This section details the correct order of operations
for using the Model G0707.
To use blast cabinet:
Prepare cabinet and workpiece for blasting as
1.
discussed in Preparation on Page 21.
2. PUT ON safety goggles and respirator.
Select and load blasting media through
3.
cabinet door. Avoid using
free silica, as this is a leading cause of
silicosis. Refer to Page 25 for media types.
Note: Loading only enough media for job
at hand will help you prevent over-using or
having to screen excess media. Typically
use just enough media to cover suction tube
opening by 6".
Install correct blast tip in position shown in
4.
Figure 20. For lower air pressure systems,
6mm tip is the best choice. Refer to Page 25
for air pressure and media options.

IMPORTANT: Maintain concentricity of tip
orifice as it wears. To do this you must rotate
media blasting tip

of use. Worn tips make an inconsistent media
spray pattern. As a result, surfaces can be
left with streaking or tear-out. Replace any tip
that has worn ⁄ " in diameter larger than its

original size.
