3.4
Loading and Unloading Parts
NOTE: Parts must be free of oil, water, grease, or
other contaminants that will clump media or clog filter
cartridge.
3.4.1
Load and unload parts through the top door.
3.4.2
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.
3.4.3
Close door; the door interlock system will prevent
blasting if door is open.
3.5
Blasting Operation
To avoid the inhalation of dust, which can
cause respiratory illness from short-term
ingestion or death from long-term ingestion.
After blasting, keep door 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.
3.5.1
Slowly open the air valve on the air-supply hose
to the cabinet. Check for air leaks on the initial startup and
periodically thereafter.
3.5.2
After the filter cartridge is seasoned, per Section
6.8, adjust the pulse pressure regulator to 60 psi. Refer to
Section 4.2 for adjustment procedure.
3.5.3
Turn ON lights and exhauster. The ON/OFF
toggle switch performs both functions.
3.5.4
Load parts.
3.5.5
Close door; the door interlock system will prevent
blasting if door is open.
3.5.6
Adjust the pilot pressure regulator to the required
blast pressure, per Section 4.1. The regulator is located
on the front right leg of the cabinet.
3.5.7
Insert hands into rubber gloves.
3.5.8
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.
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 risk 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.
3.5.9
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.
To prevent rapid frosting of the view window,
avoid pointing the blast nozzle toward the
window.
3.5.10
When blasting parts off the grate, use a solid
conductive back rest 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.
3.6
Blasting Technique
3.6.1
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.
