Operation
This polisher is for use with dry polishing materials (media). Do not use wet or water based media in
this tumbler.
This tumbler is ideal for many finishing applications including:
* Removing rust or other surface imperfections from hardware.
* Removing burrs from machined or stamped hardware
or other small parts.
* Polishing small or hard to reach small parts.
* Remove grease or other contaminants from various
metal parts.
NOTE:
Your tumbler can be used with a variety of
media, such as plastic beads, ground corn cobs, walnut
shells, etc. Many of these are available from Harbor
Freight Tools.
CAUTION:
Ceramic media will cause excessive wear
on the tumbler bowl. Do not use ceramic or other very
hard media in this tumbler.
1.
Fill the Bowl about 2/3 full with polishing media. Add metal parts as needed up to a maximum of 5
LBS. of material (including media). Do not overfill. Maximum capacity will vary with the size of the items
being polished. Overfilling will cause the polishing process to go much slower. If the tumbler is running
too slowly, simply remove some items and restart. Caution: Not having enough media in Bowl could
damage parts.
2.
Place the cover on the tumbler bowl, being sure to get the gasket correctly in place. Add the Washer
and Wing Nut to the top and hand tighten firmly.
3.
Press the Power Switch to the “ON” position ( | ).
For degreasing,
use ground corncob, walnut shell or plastic media. Tumble for 30 minutes to 1 hour.
To remove rust,
use commercially available treated plastic media. Depending on the condition of the
materials, you will have to tumble for 2 - 6 hours.
To polish,
tumble in walnut hull or corncob media. Do not add water. You may add a small amount of
commercial metal polish.
CAUTION:
Tumbling often creates dust which may be harmful to your health. Wait for at least 1 hour
after tumbling is complete and the tumbler turned OFF before opening the tumbler. This will allow the
dust to settle.
CAUTION:
Never tumble with the top off, as hazardous dust may be created, and the media or work
materials may be ejected from the tumbler.
4.
When the tumbling job is completed move the power switch to the OFF position before opening the tumbler.
