Eastwood B120 Assembly And Operating Instructions Manual page 12

• Load an object to be blasted into the Blast Cabinet through
the Side Doors or Top Lid and set it on the Perforated
Floor Panel.
• Close and securely latch the Side Doors and Top Lid.
• The included Air Regulator is used to limit incoming air
pressure. The Air Regulator should be adjusted to 90 - 125
psi while the Blasting Gun is flowing. Excessive air pressure
can cause permanent damage to the unit.
• Set Vacuum & Light Switches to ON.
• Place your hands into the gloves and grip the Blasting
Gun firmly.
• Depress and hold the Foot Pedal to discharge the blast
stream.
• It is optimal to direct the blast stream at the workpiece at
a 60°- 45° angle.
NOTE: Avoid angles of 90° (ricochet causes excess Nozzle
and Viewing Glass wear) or less than 30° (media tends to
glance off workpiece).
• Adjust the Anti-Purge Valve screw to the halfway position
as a baseline (FIG 19). Further fine tuning can be made to
perfect the flow of media. Too much air bleed will cause
underfeeding of the media. Too little air bleed will cause
media surging, as the media flow rate will exceed the
replacement rate.
• When done blasting, release Foot Pedal and allow Vacuum to
run several minutes until all dust is cleared from the Cabinet.
• Set Vacuum & Light Switches to OFF.
• Disconnect the air supply. Leave disconnected when access-
ing the Blast Cabinet or when not in use for extended periods
of time.
• You may now safely retrieve your workpiece via the Side
Doors or Top Lid.
