Operation (continued)
Maintenance
Before the first use, and once a month following, put a few drops of oil on the
1.
Driving
Shaft Set (#12)
bearings.
Check the
2.
Belt (#37)
tension. It must be kept as loose as possible without allowing it to
slip on the
Driving Pulley (#35)
. Check before each use.
Make sure the exterior of the
3.
Rubber Barrel (#22)
is clean so that it doesn’t slip on the
rollers. Wipe it with a soapy cloth, then wipe it clean with a damp cloth, and dry thoroughly.
Do not use liquid cleaners or solvents.
Polish:
Gently set the stones in the
Rubber Barrel (#22)
. Charge the tumbler with fresh water, pol-
ishing compound, and plastic pellets to help cushion the stones. Make sure the volume is at
least 1/2 full, preferably 3/4 full. Tumble for 5 to 7 days. If they look the same dry as they do
wet, then they are finished. If they have a slight film, they need to be burnished.
Burnishing:
Remove the stones, clean the
Rubber Barrel (#22)
and remove and recover the plastic pellets
(set aside). Place the stones back in the
Rubber Barrel (#22)
and replace the same pellets.
Use powdered soap such as
Ivory
®
or White King
®
(see chart on page 5)
.
Do not use liquid
detergents or dishwasher powders that have bleach. Add water as in previous steps and seal
the
Rubber Barrel (#22)
. Tumble for four days, and clean the barrel.
Notes to remember:
You must clean between steps.
1.
When polishing or burnishing you must use plastic pellets.
2.
It is recommended to use a log book to keep track of each step.
3.
If you start with stream worn or smooth stones, you may be able to eliminate the first
4.
step.
It is advised that you purchase a mineral book which goes into more detail about selection
5.
of stones for tumbling. As you learn about relative hardness of each stone you will achieve
greater success by not mixing soft and hard stones.
Always dispose of material properly.
