Manual No. 23425, Rev. C, 07/19
4.4.2
Load and unload parts through either door.
4.4.3
When blasting small parts or objects having small
pieces that could become dislodged and fall off, place an
appropriately sized screen over the grate (or under the
grate when frequently blasting small parts) to prevent
parts from falling into the hopper. If an object should fall
through the grate, stop blasting immediately and
retrieve it.
4.4.4
Close door; the door interlock system will
prevent blasting if either door is open.
4.5
Blasting Operation
WARNING
To avoid the inhalation of dust, which can
cause respiratory illness from short-term
ingestion or death from long-term ingestion:
Use the blow-off nozzle to blow media off
parts before opening doors.
After blasting, keep doors closed and
exhauster running until the cabinet is clear
of all airborne dust.
Always close cabinet, reclaimer, and dust-
collector doors before blasting. Keep all
doors closed during blasting.
Always wear blast gloves.
Stop blasting immediately if dust leaks are
detected. Refer to troubleshooting Sections
8.15 and 8.16 and identify source of leak.
4.5.1
Slowly open the air-supply to the cabinet. Check
for air leaks on the initial startup and periodically
thereafter.
4.5.2
After the filter cartridges are seasoned, per
Section 7.9, adjust the pulse pressure regulator to 60
psi. Refer to Section 5.7 for adjustment procedure.
4.5.3
Turn ON lights and exhauster. The push-button
switches, located on the cabinet front, performs both
functions.
4.5.4
Load parts. If parts are oily or greasy, degrease
and dry them prior to blasting.
4.5.5
Close door; the door interlock system will
prevent blasting if either door is open.
4.5.6
Adjust the pilot pressure regulator to the
required blast pressure, per Section 5.1. The regulator is
located on the top, left side of the cabinet.
4.5.7
Insert hands into blast gloves.
4.5.8
To blast, hold the gun firmly, point the gun
toward the object to be blasted, and apply foot pressure to
the top of the foot pedal; blasting will begin immediately.
WARNING
Shut down the cabinet immediately if dust leaks
are detected from the dust collector or cabinet.
Make sure the dust-collector filter(s) are
correctly seated and not worn or damaged.
Prolonged breathing of any dust can result in
serious lung disease or death. Short-term
ingestion of toxic dust, such as lead, poses an
immediate danger to health. Toxicity and health
risks vary with type of media and dust
generated by blasting. Identify all material being
removed by blasting and obtain a safety data
sheet (SDS) for the blast media.
NOTICE
To prevent rapid frosting of the view window,
avoid pointing the blast nozzle toward the
window and install a view-window cover lens,
per Section 7.3.
4.5.9
When holding parts off the grate, use a solid
conductive backrest to support the part. Without this
assist, especially with longer blasting operations, the
operator will tire easily from resisting blast pressure, and
static electricity could build up in the ungrounded part
and cause static shocks. Whenever possible, avoid
holding small parts that require blasting into the glove.
4.5.10
If an object should fall through the grate, stop
blasting immediately and retrieve it.
4.6
Blasting Technique
4.6.1
Blasting technique is similar to spray painting
technique. Smooth continuous strokes are usually most
effective. The distance from the part affects size of blast
pattern. Under normal conditions, hold the gun
approximately 3" to 6" from the surface of the part.
4.7
Stop Blasting
4.7.1
To stop blasting, remove foot pressure from the
top of the foot pedal.
4.7.2
Use the blow-off nozzle to blow media off
cleaned parts.
