How to use Ultrasonic Cleaner

Be sure to fill the cleaning tank, etc. with the appropriate amount of cleaning solution before operation.
Fill the tank at least half full with cleaning solution. If the machine is equipped with a heater, fill the tank at least 80% full.
Use of the machine with no cleaning solution (empty tank) or with a low level of cleaning solution may result in a malfunction.

Do not place beakers or cleaning materials directly on the surface.　Doing so may result in overheating or abnormal ultrasonic vibration, which may cause a malfunction.
Use the optional cleaning basket or beaker rack.
For cleaning baskets and beaker racks, see Optional Items.

Optional Item Information

Items that cannot be ultrasonically cleaned (typical examples)
Jewelry with scratches or cracks may have the scratches or cracks spread by ultrasonic vibration.
Also, do not clean pearls, tortoiseshell, etc.
Even if the body of a watch is waterproof, ultrasonic vibration may cause water to enter the watch, resulting in a malfunction.

Dirt on the ultrasonic vibration surface may cause malfunction.
Please clean regularly.
