4.0
OPERATION
4.1
Season Filter Cartridge
NOTICE
Do not pulse a new dust collector or
replacement filter cartridge until the cartridge is
seasoned, per Section 7.9. . Pulsing
unseasoned cartridges can cause premature
cartridge failure and decrease the efficiency of
dust collectors.
4.2
Media Loading
4.2.1 Media capacity:
Media capacity of the Pulsar
Pressure Cabinet is approximately 1 cuft. Full capacity is
when media is at the level of the pop-up valve.
Overfilling will result in media carryover to the dust
collector and possibly a blockage in the conveying hose.
4.2.2 Media loading:
With the exhauster OFF, add
clean, dry media by pouring it into the reclaimer through
the reclaimer fill door.
Do not pour media directly into
the cabinet hopper, as overfilling or blockage may
occur.
Overfilling will result in media carryover to the
dust collector and possible blockage in the conveying
hose. Refill only after all media has been recovered from
the cabinet.
4.3
Media Unloading
4.3.1
To empty the cabinet and blast machine of
media, turn ON the exhauster and blow off the cabinet
interior until all media is recovered from the cabinet.
Reduce pressure to 40 psi. Place an empty container,
such as a bucket, on the cabinet grating. Remove the
nozzle and nozzle washer, close the door, close the
choke valve, and press the foot pedal. Direct media flow
into the container. Empty the container when full or
before it is too heavy to handle, and repeat the process
until the machine is empty. Clean the nozzle holder
threads before reinstalling the nozzle washer and
nozzle. If complete purging of media is required, use a
vacuum to remove media residue in the cabinet hopper
and blast machine head.
4.4
Loading and Unloading Parts
4.4.1
Parts must be free of oil, water, grease, or other
contaminants that will clump media, or clog filters.
4.4.2
Load and unload parts through either door.
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.
4.4.3
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.
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.
4.5.1
Slowly open the air valve on the air-supply hose
to the cabinet. Check for air leaks on the initial startup
and periodically thereafter.
4.5.2
After the filter cartridge is seasoned, per Section
7.9, refer to Section 5.5 and adjust the pulse pressure
regulator to 60 psi.
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.
