Operating Instructions
The KomeStone K5 Rock Tumbler features digital controls for precise operation. Follow these steps for each tumbling stage:
1. Preparing the Barrel
- Add Rocks: Place your rough gemstones into the rubber barrel. Fill the barrel approximately 2/3 full with rocks.
- Add Grit: Refer to the included step-by-step guide for the correct amount of grit for the current tumbling stage (Coarse, Medium, Fine, or Polish). Add the specified grit to the barrel.
- Add Water: Add water to the barrel until it just covers the rocks and grit. Do not overfill.
- Seal Barrel: Securely close the barrel lid to prevent leaks during operation.

3. Tumbling Process
- Set Timer and Speed: Use the +/- buttons to set the desired number of days and speed for the current grit stage. Consult your step-by-step guide for recommended settings.
- Start Tumbling: Press the ON/OFF button to begin the tumbling cycle.
- Monitoring: Periodically check the tumbler for proper operation. The noise-reducing design minimizes sound, but ensure the barrel is rotating smoothly.
- Changing Grits: After each stage is complete, turn off the tumbler, remove the barrel, and carefully empty its contents into the sifter. Rinse the rocks and the barrel thoroughly to remove all traces of the previous grit before proceeding to the next stage. It is crucial to prevent mixing grits.
- Repeat: Follow the process for all four grit stages to achieve polished gemstones.
Maintenance
- Cleaning the Barrel: After each tumbling stage, thoroughly clean the inside and outside of the rubber barrel with water to remove all grit residue.
- Cleaning the Base: Wipe down the tumbler base and rollers with a damp cloth. Ensure no grit or water enters the motor housing.
- Belt Inspection: Regularly inspect the drive belts for wear and tear. If a belt appears stretched, cracked, or broken, replace it with one of the provided spare belts.
- Storage: When not in use, store the tumbler in a clean, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Tumbler not turning on. | Power cord not properly connected; power outlet not active. | Check power connections. Test the outlet with another device. |
| Barrel not rotating. | Drive belt is loose, broken, or dislodged; barrel overloaded. | Inspect and adjust/replace the drive belt. Reduce the amount of rocks in the barrel. |
