G0474/G0475 Sandblasters
-11-
10. Close the blast nozzle lever, and turn the
compressor on (see Figure 11).
11. Adjust the air supply line regulator to an air
pressure between 65-125 PSI, depending on
your requirements.
12. Move the tank air supply lever to ON or the
open posi
tion (Figure 12), and the tank will
pressurize to your regulated air pressure
indicated by the tank gauge.
Note: If the tank relief valve trips open and
exhausts air, immediately
turn the compressor
off and correct the over-pressurization
problem with the compressor. If the tank
exceeds its rated pressure, it may explode,
causing severe injury or death.
6. Point the blast nozzle in a safe direction, and
slowly move the blast nozzle lever to the ON
or open position to exhaust any air from the
tank (see Figure 10).
7. Make sure the air pressure gauge reads zero
(see Figure 10).
8. Remove the filler cap, insert the funnel, and
carefully—without causing a hazardous dust
cloud—pour or spade-in the abrasive into the
sandblaster. Use only enough abrasive for
your project.
Note: For the Model G0475 10 gallon tank,
you can use up to 40 lbs of abrasive, or you
can fill the tank to
3
⁄4 full. The Model G0474 20
gallon tank can use up to 80 lbs of abrasive,
or be filled to
3
⁄4 also.
Note:
If you fill the tank to
3
⁄4 full, and the local
humidity is 90-100%, the water trap will not
be able to trap all of the moisture from the
compressed air. So you must reduce the load
of abrasive and fill the tank more often and
empty the water trap more often. Otherwise,
the sand will clog in the tank outlet and in the
blast hose.
9. Brush sand away from the sealing cap and
O-ring, and close the filler cap.
