INTRODUCTION

Congratulations on your purchase of a Barranca Diamond BR-6 Rotary Rock Tumbler. We are cer­tain that you will be pleased with your purchase.

The following are safety and general guidelines for polishing rocks. Rock tumbling is not an exact
science. After a few batches you will discover your own techniques and make modification to suit
your specific needs. When selecting rocks to tumble, remember the finished product is determined
by the quality of rocks with which you start.

Read and follow all safety and operating instructions. If you have any questions concerning your
Barranca Diamond BR-6 Rotary Rock Tumbler, please feel free to call customer service at

ELECTRICAL REQUIREMENTS AND GROUNDING INSTRUCTIONS

In case of a malfunction or breakdown, grounding provides a path of least resistance for electric cur­rent to reduce the risk of electric shock. This tool is equipped with an electric cord having an equip­ment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet
that is properly installed and grounded in accordance with all local codes and ordinances.

WARNING

In order to prevent potential electrical shock and injury, the following electrical
safety precautions and symbols should be followed at all times!

BR-6 SAFETY

• Do not modify the plug provided – if it will not t the outlet; have the proper outlet installed by a

qualied electrician.

• Improper connections of the equipment-grounding conductor can result in a risk of electric shock.
The equipment grounding conductor is the insulated conductor that has an outer surface that is
green, with or without yellow stripes. If repair or replacement of the electric cord or plug is
necessary, do not connect the equipment-grounding conductor to a live terminal.

• Check with a qualied electrician or service personnel if the grounding instructions are not
completely understood, or if in doubt as to whether the tool is properly grounded.

• Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that
accept the tool’s plug.

• Repair or replace a damaged or worn cord immediately.

WARNING

This tool is intended for use on a circuit that has an outlet that looks like the one shown in Sketch A.
The tool has a grounding plug that looks like the plug illustrated in Sketch A. A temporary adapter,
which looks like the adapter illustrated in Sketches B and C, may be used to connect this plug to a
2-pole receptacle as shown in Sketch B, if a properly grounded outlet is not available. The temporary
adapter should be used only until a properly grounded outlet can be installed by a qualied electri­cian. The green-colored rigid ear, plug, and the like, extending from the adapter, must be connected
to a permanent ground such as a properly grounded outlet box.

NOTE: Use of a temporary adapter is not permitted in Canada.

BR-6 SAFETY

WARNING

To reduce the risk of electrocution, keep all connections dry and off the ground. A Ground Fault
Circuit Interrupter (GFCI) should be provided on the circuit(s) or outlet(s) to be used for this machine.
Receptacles are available having built-in GFCI protections and may be used for this measure of
safety. When using an extension cord, the GFCI should be installed closest to the power source,
followed by the extension cord and lastly, the machine.

DANGER

WARNING

Use only extensions cords that are intended for outdoor use. These extension cords are identied
by a marking “Acceptable for use with outdoor appliances; store indoors while not in use.” Use only
extension cords having an electrical rating not less than the rating of the product. Do not use dam­aged extension cords. Examine extension cords before using and replace if damaged. Do not abuse
extension cords and do not yank on any cord to disconnect. Keep cords away from heat and sharp
edges. Always disconnect the extension cord from the receptacle before disconnecting the product
from the extension cord.

WARNING

To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch the
plug with wet hands.

WARNING

Use of undersized extension cords result in low voltage to the motor that can result in motor burnout
and premature failure. Barranca Diamond warns that equipment returned to us showing signs of being
run in a low voltage condition, through the use of undersized extension cords, will be repaired or re­placed totally at the customer's expense. There will be no warranty claim.

DO NOT use in wet conditions.

To choose the proper extension cord,

• Locate the length of extension cord needed in table provided.

• Once the proper length is found, move down the column to obtain the correct AWG size required
for that length of extension cord. For example, a fty foot extension cord would require an AWG

size of 14 for a 120V volt circuit.

BR-6 INFORMATION

INFORMATION

For best results, select gemstones of similar hardness and roughness to tumble together. Ideally,
your drum should use about 6 lbs. of gem stones. Rocks may vary in size.

There are 4 steps in the rock tumbling process:

1. 60-90 grit silicon carbide

2. 220 grit silicon carbide

3. Pre-polish (400 or 600 grit silicon carbide)

4. Cerium oxide or aluminum oxide final polish

Seven days (162 hours) are needed to complete each of the 4 steps. More time may be needed
depending on the hardness of the rock. The optimum objective for rock tumbling is to obtain a slurry
that coats the stones during the tumbling process. Learn to tell by the feel of the slurry when the grit
is worn out and you need to rinse the rock and drum, then add fresh grit. At the end of the 28 days,
you will see your batch of beautiful, shiny, tumbled stones.

Rock Tumbling Formula:

1. 1/2 cup 60-90 grit (silicon carbide) & 6 oz. water

2. 1/2 cup 220 grit (silicon carbide) & 6 oz. water

3. 1/2 cup pre-polish (400 or 600 grit silicon carbide) and 4 oz. water

4. 1/2 cup cerium oxide or aluminum oxide & 4 oz. water

ASSEMBLY AND SETUP

1. Place the BR-6 Rock

Tumbler on a firm, smooth,

level surface

2. Slide the barrel onto

the shaft and tighten the

thumbscrew onto the flat of the

shaft. Plug in Rock Tumbler

3. Remove cap from barrel

BR-6 INSTRUCTIONS

INSTRUCTIONS

5. Add 1/2 cup 60-90 grit (silicon carbide).

6. Add 6 oz. of water, a little at a time until the grit starts to cling to the rocks. Too much water will
tend to rinse the grit back off the rocks.

7. Check the stones every couple days and add small amounts of water if the slurry seems too
thick.

8. Before proceeding to each next step, you need to open the barrel, add 3 tablespoons of
dishwashing soap and 1 additional cup of water to the barrel and run the tumbler for 5 – 10
minutes. This short pre-cleaning process de-slurries your stones before you empty the barrel and
cleans your stones and barrel to prepare for the next grit.

9. Rinse the rock carefully, it should be removed from the barrel and both the rock and the barrel
cleaned thoroughly.

10. Add 1/2 cup 220 grit (silicon carbide) and 6 oz. of water.

11. Repeat steps 7 through 9. Plastic pellets may be used during this step if your barrel is less than
3/4 capacity.

12. Add 1/2 cup pre-polish (400 or 600 grit silicon carbide) and 4 oz. of water.

13. Repeat steps 7 through 9. Plastic pellets may be used during this step if your barrel is less than
3/4 capacity.

14. Add 1/2 cup cerium oxide or aluminum oxide and 4 oz. of water.

NOTE: Be sure to rinse the rock carefully, it should be removed from the barrel and both the rock
and the barrel cleaned before proceeding to the next grit.

NOTE: Never dispose of the sludge from the tumbler down a drain as the grinding compound is very
hard and will settle out and plug your drain.

NOTE: Do not cover unit with anything as this may block air flow and cause the motor to overheat,
or possible fire hazard.

NOTE: Export version of the BR-6 Rotary Rock Tumble with a 220 volt, 50 Hz gear motor available
