Frequently Asked Questions - KD-C3012 Vevor

How to start the machine?

Place the barrel filled with stones and water onto the base, plug in the machine, then press the Start/Stop button. Select speed (1-9) and time (1-9 days) using the knobs. The machine starts the cycle.

What to do if the machine shows E1?

The code E1 indicates an overload. Turn off the machine, remove excess weight from the barrel (do not exceed 4 lb), then turn on again. The machine will resume with previous settings.

What to do if the machine shows E2?

The code E2 appears if the barrel is missing or jammed for more than one minute. Properly place the barrel or clear the obstruction, then press the Start button to continue.

How to open the barrel lid?

Unscrew the black knob of the lid, remove the outer stainless steel lid (use a flat object if necessary), then remove the inner lid by pressing the barrel to push it outward.

How much water should be added?

Fill the barrel about two-thirds full with water until the water just covers the top of the stones. Do not overfill to avoid poor polishing.

How long does the polishing take?

A complete cycle includes four steps (coarse grit 320#, medium grit 600#, fine grit 800#, polishing powder). Each step lasts 1 to 9 days depending on the hardness of the stones and the speed selected.

Can I use any stones?

Yes, but harder stones require longer cycles. Avoid very soft or cracked stones. Start with stones of similar hardness for a uniform result.

How to clean the barrel between cycles?

Empty the contents into the strainer, rinse the stones and barrel with clean water outdoors to avoid clogging drains. Make sure no abrasive residue remains.

Can the machine run continuously unsupervised?

Yes, it is designed for continuous operation. It automatically stops after the set time. In case of power outage, the memory resumes the cycle. Monitor the first cycles to check for leaks.

Where can I find spare parts or support?

Tumbling Cycles Guide

Please add proper amount of water for every stage and follow the table below for the best polish effect.

Generally speaking, a rough polish needs a faster speed and fine polish needs slower speed.

One complete cycle	Stage	Emery grit /weight	Ceramic abrasive/weight	Speed	Time(day)
	1	320#/60g	5mm/400g	1-9 speeds adjustable according to the stone hardness and weight	1-9 days adjustable according to the stone hardness and weight
	2	600#/60g	5mm/400g
	3	800#/60g	5mm/400g
	4	Brightening powder/60g	5mm/400g
Note: All the contents don’t exceed 4Lb, if over 4Lb, the machine will speed 1-2. Need to raise the speed.

Overload function: overload will stop working and show E1. It needs to power off and remove the overload and stuck place, then power on again. The machine will work normally with previous working time and speed.

If you don't put the bucket in or something gets stuck for 1 minute, it will show an error. After you put the bucket in or clear the stuck, press the start button to continue working.

Harder stones take longer to polish.

Polishing Your Gemstones
	4. Put rocks inside the tumbler barrel.(Fo example, stones about 300-400 grams, 40 grams of round abrasive and adding two-thirds of the barrel of water)Don't overload it! If the tumbler barrel is full, the rocks won't move around enough become polished. We recommend that yo the barrel 1/2 to 2/3 full.Note: If you overfill the barrel,the stone hang over the edge of the barrel and w polished.
	5. Empty the contents of the grit #1 pa into the barrel.
	6. Add water to the barrel until the wate covers the top of the rocks.
	7. Place one side of the lid in the seal angle.
	8. Do not press the entire lid directly in seal.
	9. Push the seal ring on the other edge
	10. After confirming the push seal ring, t seal ring is inside the polishing barrel.11. Put back the stainless steel cover or of the inner lid and reattach the knob a tighten it. Make sure to tighten the best can to ensure the barrel does not leak water.
	12. Place the tumbler barrel onto the tur base, with the lid facing to the right.
	13. Plug in the machine, press the On/C button and select the appropriate number days and speed (refer to the Tumbling Guide on page 4), and let the machine job!
	14. You can always pause the machine without losing the speed and timer setting pressing the Pause/Resume button. Press again to resume.

In the first stage: Add 320# emery grit and ceramic abrasive, with 1-9 adjustable according to the stone hardness. Higher speed will round the rocks more quickly.

In the second stage: Add 600# emery grit and ceramic abrasive, adjustable according to the stone hardness. Higher speed can fine the rock surface.

In the third stage: Add 800# emery grit and ceramic abrasives, with 1 adjustable according to the stone hardness. Slower speed will make the surface smoother.

In the fourth stage: Add brightening powder and ceramic abrasive, with speeds adjustable according to the stone hardness. Slower speed can increase the brightness of rocks.

Cycle Change

1. When the tumble cycle is done, pour the tumbler barrel into the mesh strainer, rinse the rocks and barrel with water to remove all the grit.

Caution! Never pour used grit down a drain inside your house - it will destroy the plumbing! Make sure to wash your stones and barrel outside instead of in your bathroom or kitchen.

Check before you discard! The purpose of each grit cycle is to gradually smooth the rocks and round out the edges. Whenever you finish a cycle, it's a good idea to wash off just a few of the rocks to see if they are tumbled to your satisfaction before you dump the contents of the barrel. If they aren't polished enough, return them into the barrel and let them run longer. In general, the longer the cycle, the better the results.

Trust yourself. Use your own judgment to determine if the rocks are polished to your satisfaction. Some rocks are harder than others, so they may need more time in any grit cycle than is recommended here.

1. Repeat the above steps with grits #2-4, in order. By doing so, you will bit-polish the rough rocks into smooth gemstones.

Feel free to experiment with the duration of your tumbling. Each rock you use is made of different material and so will respond differently. This is a great way to inspire experimentation!

Next Steps

Use mineral oil for extra shine! If you want your finished stones to be really shiny, coat and polish the stones with mineral oil.

You can use the included jewelry hardware to make a necklace, ring, keychain, and a pair of clip-on earrings or pins with your polished stones.

To make a keychain or necklace, simply insert the stone into the keychain/necklace cages, without using glue, by forcing it into the cage.

To make a ring or earrings, you'll need to glue the stone by using a hot gel an all-purpose adhesive sealant. Please have an adult help you if you are using glue!

Imitating Nature

The original rock tumbler is all natural - it's water! If you've ever picked up on the beach or near a river, you know what this means. Those rocks have smoothed and rounded by water over long periods of time to make them look feel the way they do.

Here's how it works: Over tens, hundreds, and even thousands of years, rock tossed around in the waves and currents of rivers and seas, banging against other. The sand and sediment act as abrasives and further smooth the rocks When the rocks are wet, the sheen gives stones a highly polished look.

Since the beginning of civilization, humanity has tried to find ways to polish faster than nature. In ancient Egypt, slaves would take roughly-cut rocks and them back and forth in troughs filled with sand and water - a process that

months - to achieve polished stones.

In India, stones cUt into preliminary shapes were put in goatskin bags with v and roughly-ground rocks. Then, workers would roll the bag on the ground for weeks at a time.

Perhaps the first rock tumbler "machine" was invented in ancient India, where teeter- totter board rolled jars filled with pre-cut beads, water, and abrasives to create polished beads.

The problem with all of these methods is that they took extremely long amo time to achieve results and only a few rocks could be polished at once.

More Successful Methods

Modern rock tumbling began in the 1950s in Los Angeles. A rock dealer near Edward Swoboda started selling hand polished regular shaped rocks - called baroque stones - in simple settings, which become very popular. To keep up demand, he partnered with a friend, Warren Jones, to build a tumbling mach that was able to polish a larger quantity of stones in a short amount of tim with little labor.

Spurred by Swoboda's success, other inventors started producing their own versions of tumbler machines that, over time, became quieter, more durable, a able to polish larger numbers of rocks, even large enough to support wholesale efforts. By the early 1960s, a rock polishing craze had taken over the U.S. rock tumbler machines could be found in homes across the country.

What Can You DO With Polished Stones?

You've spent the past month polishing stones. Now what? Besides simply enjoying looking at them, there is a lot you can do:

Jewelry: The most common use of polished rocks is to make jewelry. You can use the jewelry fasteners included in this kit, or you can do it yourself! Wrap a wire around a single stone to create a pendant that can go on a chain, or string ribbon to create a necklace. Or, you can go to a craft store and buy materials to create key chains, earrings, pins, rings and more.

Home decor: You also can use the polished rocks to create beautiful decorations for your home. For instance, you can glue the rocks to picture frames, magnets or tree ornaments. You can use larger stones to accent flower pots or vases. You can fill a jar with rocks and create a candle holder. Use your imagination!
