Troubleshooting
If you detect a problem or have a question regarding the machine, take necessary measures by referring to the applicable
description on the following table.
If no clear answer can be obtained, contact us.

By referring to the section Fuse (P15), check that the fuse is not blown. If it is blown,check for improper connection of grounding (earth) and replace the fuse.
When the power cannot be turned on and the fuse blows after taking the above procedures, the Oscillator may have failed.

No oscillation

If oscillation occurs by pressing the test switch, check that the external connection receptacle may have failed or the external device may be defectively connected.
When oscillation will not occur even by operating the test switch, the oscillator may havefailed.
The Amplitude Volume may have set to the minimum level. Increase the volume level.

No ultrasonic oscillation

The blade was broken.

The blade is a consumable part. When the blade is worn, the load (burden) applied tothe blade becomes large, sometimes resulting in breakage. Replace the blade according to the section “Maintenance of Transducer (P18).”

Error

If the error lamp illuminates, there is a possibility of “disconnection”, “overheating”
or ”overloading.” Take necessary measures.
Check that there is no problem regarding the transducer connection or check that there
is no heat generation from the oscillator and the transducer.
For overloading, refer to the section “Machine in Overload Stoppage (P28)” and refer tothe section “Maintenance of Transducer (P18)”, as required.

I want to reset the error.

Error resetting can be done by turning on the power again. Do not try to execute error
resetting operations in a row. Do it with a five-second interval.
