Manual No. 27723, Rev. B 04/19
4.2.2
If media doesn't flow, it has caked; open the fill
door and stir media until it starts to flow. Before the
container becomes too heavy to easily manage, replace
the plug and empty the container. Replace the plug
when the reclaimer is empty or, if changing media type,
purge the media hose, as noted below.
4.2.3
To purge the media hose, before replacing the
plug turn ON the exhauster, grasp the gun, and press
the foot pedal using the gun to blow off the cabinet
interior until the air from the gun and the cabinet are
clear. Turn OFF the exhauster and replace the plug.
4.3
Loading and Unloading Parts
WARNING
Use solid fixturing to hold heavy parts in place.
Do not remove lift equipment until the part is
adequately supported to prevent movement.
Moving heavy, unsupported parts may cause
them to shift or topple and cause severe injury.
This is especially important with the use of
turntables.
4.3.1
Load and unload parts through the door.
4.3.2
Parts must be free of oil, water, grease, or other
contaminants that will clump media or clog filters. If parts
are oily or greasy, degrease and dry them prior to
blasting.
4.3.3
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.
4.3.4
Close door; the door interlock system will
prevent blasting if the door is open.
4.4
Blasting Operation
4.4.1
Slowly open the air supply to the cabinet. Check
for air leaks on the initial startup and periodically
thereafter.
4.4.2
Turn ON the lights and exhauster. The push-
button switches, located on the cabinet front, performs
both functions.
4.4.3
Load parts.
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 the door.
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.
4.4.4
Close door; the door interlock system will
prevent blasting if the door is open.
4.4.5
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.
4.4.6
Insert hands into blast gloves.
4.4.7
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
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.
