To stop blasting release the trigger.
4.7 Shutdown
4.7.1
When finished blasting, remove the lance from
the abrasive and shake abrasive from the material hose.
If conditions are safe to do so, pull the trigger to further
empty the hose.
4.7.2
Depressurize the air-supply line and shut down
the compressor.
4.7.3
For H2O models, shut off the water supply, drain
the water hose, and disconnect the hose.
5.0 ADJUSTMENTS
5.1
Blast Pressure
‒
Figure 9
To reduce blast pressure rotate the control knob
clockwise. Reduced pressure is caused from reducing
the air volume through the gun. If greater control is
required, install a pressure regulator in the air-supply
line.
5.1.1
The control knob adjusts the force of air (blast
pressure) coming out the nozzle. Turning the knob
clockwise decreases the blasting force for delicate jobs,
and turning it counterclockwise increases the blast force
for tougher jobs.

Positioning of Hose and Gun
‒
Figure 10
5.2.1
Whether the operator is left or right handed
could determine the most comfortable positioning of the
handle grip and material hose. To change the orientation
of the material hose with that of the handle grip, loosen
the three setscrews securing the mixing chamber to the
air-jet assembly.

5.2.2
Rotate the mixing chamber to obtain the most
comfortable position while holding the gun assembly and
material hose.
5.2.3
Make sure the jet is fully seated into the mixing
chamber before tightening the setscrews.
