Thank you for purchasing this ultrasonic cleaner. Please take some time to read these operating instructions before use and keep them for future reference. Failure to follow these instructions may lead to serious artificial damages to the product.

ULTRASONIC PRINCIPLE

| Ultrasonic cleaning is based on the cavitation effect caused by high-frequency ultrasonic wave vibration signal in the fluid. Microscopic bubbles are formed, and then implode violently causing cavitation which creates an intense scrubbing action on the surface of the item being cleaned. The bubbles are small enough to penetrate microscopic crevices, cleaning them thoroughly and consistently.
Ultrasonic cleaning is extremely effective at removing dirt and grime which would normally require tedious manual cleaning by hand. It has been used to clean a wide variety of instruments and mechanical parts such as carburetors, returning them to almost “like new” condition without damage to delicate parts.

SAFETY PRECAUTIONS

• Make sure the voltage value is within the default voltage range.
• Don’t remold this machine.
• Please prevent the control panel from being eroded by detergent, acid, or alkali solution, etc.
• Make sure the ground wire is well-connected with the machine before using the machine.

APPLICATIONS

This list is almost endless. Provided the product is nonporous and can normally be immersed in water, it can be thoroughly cleaned. Here are some examples:

• Jewelry especially gold, silver & platinum
• Watchstraps
• Coins and other collectibles
• Small PCB Boards
• Toothbrushes & Dentures
• Electrical components
• Make-up cases
• Tattoo needles
• Knives, bayonets, and other militaria

Ultrasonic cleaning is not recommended to be used to clean the following gemstones: Opal, Pearl, Emerald, Tanzanite, Malachite, Turquoise, Lapis, and Coral.

OPERATION

1. Fill at least 2/3 of the stainless steel tank with a cleaning solution. Based on cleaning requirements, a small amount of cleaning solution is recommended because it will help to increase the cleaning performance.

2. Dismantle the spare parts to be cleaned as possible as you can, and remove the dirt, oil contaminants, carbon deposit, etc with a high-pressure jet, wire brush,scraper knife, or other tools so as to prolong the service life of the cleaning solution and ensure the cleaning speed and performance.

3.  Put the spare parts to be cleaned into the tank and make them fully immersed, but not overlapped as possible as you can.

4. Start ultrasonic cleaning:
   A. Connect the power socket on the back to power with the power cord (the red indicator will turn on and the LED screen will display “180”.)
   B. Press the “TIME” button to switch the cleaning time in the following time circulation: 90→ 120→ 150→ 180→ 210→ 240→ 270→ 300→ 330→ 360→ 540→ 720→ 900→18. →21. →24. →27. → 30.→ 90 (18 cleaning times in total).
   C. Press the “ON/OFF” button once to make the machine start cleaning. The blue ultrasonic indicator turns on, the setting time starts counting down. When the time reaches “886”, the machine stops working automatically. Besides, the ultrasonic cleaning can also be stopped by pressing “ON/OFF” once again.
   D. Unplug the power cord, pour the cleaning solution, clean the tank and the housing with a clean cloth.

5. In order to enhance the cleaning effect, you can add the appropriate amount of detergent into the cleaning solution or prolong the cleaning time.

6. The machine will stop working after 45 minutes of continuous work and can start working again after 4 minutes break.
