First、It is forbidden to put conductive liquid (such as water) into the air inlet on the top of the ultrasonic control cabinet. Otherwise, the pipeline system of the cleaning machine will be seriously damaged.

　　Second、Be careful to keep the ultrasonic cleaner clean. Turn off the power supply when not in use.

　　Third、Do not collide or shake violently on the ultrasonic cleaner.

　　Fourth、Keep the ultrasonic cleaner away from the heat source.

　　Fifth、Machines should be avoided in humid environment, long-term storage can easily lead to equipment oxidation rust, wet lines.

　　Sixth、The continuous working time of the ultrasonic cleaning machine should not exceed 4 hours. If the continuous working time is too long, the adjusting knob of the ultrasonic cleaner should be rotated to the "0" position. The cooling fan should continue to work. If the ultrasonic cleaning does not start, the continuous heat dissipation in the ultrasonic control cabinet should be at least 2 minutes.

　　Seventh、After a long period of operation, the power knob should be set to zero before shutdown, and the fan should be used to work for 3-6 minutes before shutdown, so as to ensure that the internal heat of the power dissipates.

　　Eighth、After cleaning, the cleaning fluid of the ultrasonic cleaner should be precipitated, filtered or replaced in time to ensure the cleaning effect.
