1. Prepare Rocks: Select rough rocks that are suitable for tumbling. Clean them thoroughly to remove any loose dirt or debris.
2. Load Barrel: Fill the barrel approximately 2/3 full with your chosen rocks. A mix of different sizes is recommended for better tumbling action.
3. Add Grit and Water: Refer to your grit manufacturer's instructions for the correct amount of abrasive grit for a 3LB barrel. Add the grit, then add water until it just covers the top layer of rocks. Leave some air space for tumbling action.
4. Seal Barrel: Securely place the lid on the barrel. Ensure the double stainless steel top cover is tightly sealed to prevent any leakage during operation.
5. Place Barrel on Tumbler: Carefully place the sealed barrel onto the rollers of the tumbler base. Ensure it sits centrally and can rotate freely.
6. Start Tumbling: Turn the On/Off-Reset switch to the 'On' position. The barrel will begin to rotate.
7. Monitor: Allow the tumbler to run continuously for the duration specified by your grit manufacturer (typically 7-10 days per stage). Periodically check for proper rotation and listen for unusual noises.
8. Clean and Repeat: After each stage, turn off the tumbler, unplug it, and carefully remove the barrel. Open the barrel and thoroughly clean the rocks and the inside of the barrel to remove all traces of the previous grit. Proceed to the next stage with finer grit and fresh water.
9. Final Polish: After the final polishing stage, clean the rocks and barrel thoroughly. Your rocks should now be smooth and shiny.

7. Maintenance

Regular maintenance ensures the longevity and efficient operation of your Leegol Electric Rock Tumbler.

• Cleaning the Barrel: After each tumbling stage, thoroughly wash the inside and outside of the barrel to remove all grit residue. Grit can damage the barrel and the tumbler mechanism if not removed.
• Cleaning the Base: Periodically wipe down the tumbler base with a damp cloth. Ensure no water enters the motor housing.
• Belt Inspection and Replacement: Inspect the drive belt regularly for wear, cracks, or stretching. If the belt appears worn or the barrel is not rotating consistently, replace the belt. Replacement belts can be purchased from authorized dealers.
• Lubrication: Apply a drop or two of light machine oil (e.g., mineral oil) to the motor bushings and where the rotary parts meet other metal components every few months or as needed. Do not apply oil to the drive belt or gears.
• Airflow: Ensure the motor housing vents are clear of dust and debris to maintain proper airflow and prevent overheating.
