KECOOLKE SU-777 Ultrasonic Jewelry Cleaning Machine, 750ml Sonic Cleaner with Digital Timer

Overview

The KECOOLKE Ultrasonic Jewelry Cleaning Machine is a 750ml capacity sonic cleaner designed for cleaning small items using high-frequency sound waves. It features a digital timer with multiple preset cycles.

Features

Ultrasonic Cleaning Technology

The cleaner operates at a vibration frequency of 48,000 times per second (48 kHz). This generates micro-vibrations in the water to dislodge dirt from small parts, crevices, and surfaces that are difficult to reach with manual brushing.

Digital Timer & Operation

The device has a simple one-button operation. Pressing the button starts the cleaning cycle, and a digital display shows the remaining cleaning time. The machine will automatically shut off when the cycle is complete.

Five preset timer modes are available:

• 90 seconds
• 180 seconds
• 300 seconds
• 480 seconds
• 600 seconds

Large Capacity Tank

The stainless steel cleaning tank has a capacity of 750 milliliters, suitable for cleaning multiple items at once.

Included Accessories

• Cleaning basket

Safety & Warnings

• Read all instructions before use.
• This appliance is for household use only.

• Caution for Delicate Items: Do not clean items with loose stones, glued components, pearls, opals, coral, amber, or other porous or delicate gemstones, as ultrasonic cleaning may damage them.
• Do not clean wood, ivory, or painted items.
• Always check manufacturer care instructions for any item before cleaning.

Care & Maintenance

Troubleshooting

Problem: Unit does not turn on.
Solution: Ensure the power cord is securely plugged into a working electrical outlet. Check that the lid is properly closed.

Problem: No vibration or sound is heard during operation.
Solution: Ensure the tank is filled with liquid to the appropriate level. The unit will not operate without sufficient liquid.

Problem: Cleaning results are unsatisfactory.
Solution: Use a recommended ultrasonic cleaning solution instead of plain water for tough grime. Ensure items are fully submerged and not shielded by the basket. Try a longer cleaning cycle. Pre-rinse heavily soiled items.

Problem: Unit stops before the timer ends.
Solution: The unit may have an automatic overheat protection feature. Unplug the unit and allow it to cool down for 30-60 minutes before resuming use.
