4.4.3
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.
4.5.1
Slowly open the air valve on the air-supply hose
to the cabinet. Check for air leaks on the initial start up
and periodically thereafter.
4.5.2
After the filter cartridge is seasoned, per Section
7.10, adjust the pulse pressure regulator to 60 psi. Refer
to Section 5.6 for adjustment procedure.
4.5.3
Turn ON lights and exhauster. The ON/OFF
toggle switch performs both functions.
4.5.4
Load parts.
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 rubber gloves.
4.5.8
To blast, hold the gun firmly, point the gun
toward the object to be blasted, and apply pressure to
the top of the foot pedal; blasting will begin almost
immediately.
WARNING
Shut down the cabinet immediately if dust
discharges from the dust collector or cabinet.
Check to make sure the dust-collector filter
cartridge is correctly seated and that it is not
worn or otherwise damaged. Prolonged
breathing of any dust can result in serious lung
disease. Short-term ingestion of toxic dust,
such as lead or heavy metals, 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.
4.5.9
When blasting small parts, place an appropriately
sized screen over the grate to prevent parts from falling
into the hopper. If an object should fall through the grate,
stop blasting immediately and retrieve it.
NOTICE
To prevent rapid frosting of the view window,
install a view-window cover lens, per Section
7.3, and avoid pointing the blast nozzle toward
the view window
4.5.10
When blasting 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.
4.6
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.
