As shown in Figure 4. Abrasive / Polishing Media, the
RADOR

immersed in this media and the combination of agitation, the abrasive
and polishing qualities of the media, and the patented PG3 liquids all
actonthepartuntilthedesirednishinglevelisachieved.Themedia
has a useful life based on the application it is being used in and the
amount of processing that is occurring.
Once the media has degraded to one-third of its original size, it is
time to change out the media.
To change the media, carefully scoop out all of the media particles, and dispose of them according to local
regulations. Next, with a damp cloth and mild cleaning solution, clean out the envelope and wipe down the spray
nozzles to remove any sediment build-up. Also, wipe down the grate that covers the drain inside the chamber
withaplasticbristlebrush.Finally,rellthechamberwithfreshmediasuppliedbyPOSTPROCESS. NEVER use
media other than POSTPROCESS supplied abrasive and polishing media or risk damaging the machine.
The appropriate ratio of PG3 to water is designated for each
customer application but most typically the ratio is 99 parts of
water to 1 part of PG3. The RADOR has a 1.5-gallon tank, so the
correctformulawouldbe2oz.ofPG3andlltheremainderof
the tank with fresh water. The operator using the RADOR should
always ensure that the correct levels of liquid are being utilized
duringthenishingprocess.Behindtheright-sidepanel(belowthe
PG3 access opening) is the liquids tank and the RADOR drain bucket,
as shown in Figure 5. Reservoir and Drain Bucket.
The Liquids Reservoir is translucent allowing the operator to see
how
much liquid remains in the tank. It is important to note that
whenever
the tank is empty, the correct recipe of PG3 and water
should
be added to the reservoir before operation. Never run the
RADOR
without liquids.
