Attentions:

a)While the machine is working normally, ultrasonic and tank syntony gives a well-proportioned sound, and no shudder on the surface of the water, yet there is spray made by the tiny bubbles. If there are discontinuous surges, please add or release a little of washing solution in the tank, stopping the surges is good for cleaning the objects.

b)On the condition of make sure the cleaning object is cleaned, please run the machine discontinuously as far as possible(not more than 30min.),for long-time running causes temperature increment of the case, and speedup the aging of the electronic devices.

c)Flammable cleaning solution is forbidden.

d)Do not start the heater nor ultrasonic while the tank is empty.

e)Prevent water or cleaning liquid from spattering into the case or shaker.

f)When something is dropped into the tank carelessly, take it out immediately.

g)Make sure the washing liquid is not hot, and turn the ultrasonic off and pull out the plug, while changing or emptying the tank.

h)Clean the dirt in the tank after using.

i)Keep the surface of the machine clean.

When the machine is broken or the ultrasonic weakens, it may be caused by above reasons, please stop operating the machine and contact maintenance staff.
