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.

ultrasonic transducers and heater.
c）Please note that when you run heater, the liquid in the tank could vapor
in the long time period, please keep watching the level of the liquid in the tank
d）Washing liquid spatters into the shaker results in creepage and short
circuit, and burn the wafer as well.
