Operating Instructions
The rock tumbling process involves several stages, each using a different grit to progressively smooth and polish the rocks. The KomeStone K2 Elite is designed for ease of use with its intuitive controls and brushless motor for quiet operation.

Tumbling Process Steps:
- Step 1: Coarse Grinding (60 Grit)
This initial stage is for shaping and smoothing rough rocks. Fill the barrel approximately 2/3 to 3/4 full with rough rocks. Add enough Coarse Grit (Step 1) to cover the rocks, typically 2-4 tablespoons depending on the rock volume. Add water until it just covers the rocks. Securely seal the barrel with both lids and the knob.
Place the barrel onto the tumbler base. Set the desired tumbling duration using the "DAYS" controls and adjust speed if necessary. Run for 7-10 days. After this period, empty the barrel, thoroughly clean the rocks and barrel to remove all grit residue. Inspect rocks and repeat if further shaping is needed.
- Step 2: Medium Smoothing (150 Grit)
This stage refines the shaping from Step 1. Return the cleaned rocks to the barrel. Add Medium Grit (Step 2) and water as in Step 1. Securely seal the barrel. Run for 7-10 days. Clean rocks and barrel thoroughly after this stage.
- Step 3: Pre-Polishing (600 Grit)
This stage prepares the rocks for final polishing. Return the cleaned rocks to the barrel. Add Pre-Polish Grit (Step 3) and water. For best results in this stage, consider adding ceramic tumbling media to cushion the rocks and improve tumbling action, especially for smaller pieces. Securely seal the barrel. Run for 5-7 days. Clean rocks and barrel meticulously; any remaining grit from previous stages can contaminate the final polish.
- Step 4: Final Polishing (1200 Grit)
This is the final stage to achieve a brilliant shine. Return the cleaned rocks to the barrel. Add Polish Grit (Step 4) and water. Ensure the barrel and rocks are absolutely free of any coarser grit. Run for 5-7 days. Once complete, remove the polished gemstones and rinse them under clean water. They are now ready for display or crafting into jewelry.

Maintenance
Proper maintenance ensures the longevity and optimal performance of your KomeStone K2 Elite Rock Tumbler.
- Cleaning the Barrel: After each tumbling stage, thoroughly rinse the rubber barrel and its lids with clean water to remove all grit residue. Ensure no grit from a previous stage remains, as it can contaminate the next stage and prevent proper polishing.
- Cleaning the Tumbler Base: Wipe down the tumbler base with a damp cloth to remove any dust or spills. Do not submerge the base in water.
- Belt Inspection: Periodically check the drive belt for wear and tear. If the belt appears stretched, cracked, or damaged, replace it with one of the included spare belts.
- Motor Care: The K2 Elite features a brushless motor designed for durability and quiet operation. No specific user maintenance is required for the motor itself.
