1. Introduction
The KT-185 Magnetic Tumbler is designed for polishing intricate details, tiny crevices, and multiple settings on jewelry pieces. It is not intended for use on flat surfaces. This magnetic tumbler can effectively process certain rings with stones intact, such as cubic zirconia (CZ), rubies, sapphires, and diamonds. The automated polishing process significantly reduces the need for traditional methods like cyanide bombing, stripping, and thrumming. Most finishing operations are completed within 30 minutes by placing jewelry, steel pins, water, and a special burnishing compound into the acrylic bowl.

3. Operating Instructions
Follow these steps for effective jewelry polishing:
- Prepare the Bowl: Place your jewelry pieces into the acrylic bowl.
- Add Steel Pins: Add the appropriate amount of tiny steel pins (media) to the bowl. The pins are driven by powerful rotating magnets at the base.
- Add Water and Compound: Pour water into the bowl, ensuring the jewelry and pins are fully submerged. Add a small amount of special burnishing compound. Refer to the compound manufacturer's instructions for exact ratios.
- Secure the Lid: Place the lid securely on the acrylic bowl to prevent splashing and ensure proper operation.
- Start Polishing: Press the "on" button to start the magnetic tumbler.
- Monitor Process: Most finishing operations are completed in under 30 minutes. Monitor the process to achieve desired results.
- Finish: Once polishing is complete, turn off the machine, carefully remove the lid, and retrieve your polished jewelry. Rinse thoroughly to remove any remaining compound or pins.

4. Maintenance
- Cleaning the Bowl: After each use, thoroughly clean the acrylic bowl and lid with water to remove any residue from the polishing compound and jewelry.
- Cleaning Steel Pins: Periodically clean the steel pins to ensure optimal performance. Follow the manufacturer's guidelines for cleaning and storing the pins.
- Exterior Cleaning: Wipe down the exterior of the machine with a soft, damp cloth. Do not use abrasive cleaners or immerse the unit in water.
- Storage: Store the magnetic tumbler in a dry, dust-free environment when not in use.
