3.7
Stop Blasting
3.7.1
To stop blasting, remove foot pressure from the
top of the foot pedal.
3.7.2
Keep door closed and exhauster running until the
cabinet is clear of all airborne dust.
3.7.3
Unload parts.
3.8
Pulsing (Cleaning) Dust Collector Cartridge
3.8.1
The dust-collector filter cartridge is pulsed each
time the foot pedal is pressed or released. Prolonged
periods of blasting or dusty conditions may require the
cartridge to be pulsed during the blasting process, per
Section 5.2.4.
3.9
Shutdown
3.9.1
Shut off the air-supply valve, bleed the air-supply
line, and drain the compressed-air filter and dust-collector
pulse reservoir.
3.9.2
Switch OFF the lights and exhauster.

ADJUSTMENTS
4.1
Blasting Pressure (Pilot Regulator)
4.1.1
The pilot regulator (located on the front-right leg of
the cabinet), enables the user to adjust blasting pressure
while blasting to suit the application. The maximum
recommended pressure is 80 psi. Lower pressure may be
used for delicate work. Higher pressure may cause dust
or media to escape from the cabinet. Optimal production
can only be achieved when pressure is carefully monitored.
Figure 5
4.1.2
To adjust pressure, unlock the knob by pulling it
out, as shown in Figure 5, and turn it clockwise to increase
pressure or counterclockwise to decrease pressure.
Pressure may drop slightly from closed-line pressure
when blasting starts. Once operating pressure is set, push
the knob in to lock it to maintain the setting.
4.2
Pulse Pressure
‒ Figure 6
Do not pulse new dust collectors or replacement
cartridges until the cartridge is properly
seasoned. Refer to Section 6.8. Pulsing
unseasoned cartridges can cause premature
cartridge failure or decrease the efficiency of
dust collector.
4.2.1
The pulse-pressure regulator, located in the
piping behind the cabinet, is used to adjust pressure of
the dust collector pulse. After the cartridge is seasoned,
set the pulse pressure to 40 psi. When differential
pressure reaches 8 inches (as noted on the slack tube
manometer when equipped), do additional pulsing as
noted in Section 5.2.4 and increase pulse pressure by 10
psi. Continue to do additional pulsing and increase
pressure by 10 psi when differential pressure reaches 8
inches until the maximum of 80 psi is reached. Replace
the cartridge when 80 psi does not lower pressure below
8 inches or sooner if media recovery is impaired.
4.2.2
To adjust, unlock the knob by pulling it out, as
shown in Figure 6 and turn it clockwise to increase
pressure or counterclockwise to decrease pressure. Once
pressure is set, push the knob in to lock it and maintain
the setting.
Figure 6
When viewed from the knob end,
turn clockwise to increase pressure;
turn counterclockwise to decrease pressure.
