Operating Procedure

５-１（表示器等のランプが点灯します

Without Foot Switch（１）Always confirm that the AC power cord has been fully inserted into the socket of the power pack, and plug it in an outlet.
（２）Fully connect the plug of the curl cord of a handpiece with the ULTRA SONIC socket.
（３）Turn the power control knob all the way to the left (counter-clockwise).
（４）Turn the main switch on (Power light will be on).

Explanation for Drive Modes of Handpiece●STROKE CONTROL
Voltage is increased/decreased for stable amplitude amount of handpiece.
STROKE CONTROL mode is suitable for heavy-load works such as deburring and rough finishing because it tries to keep
constant amplitude amount.
POWER MODE is effective for heavy-load works because it tries to keep constant amplitude amount.
Use VOLTAGE CONTROL mode or decrease amplitude amount in case mounted tool was burned and/or fractured.

※After the main switch is on, all the lights are also on. Follow the next step when all these lights become in normal.

＜Cautions＞※Do not use handpiece if "oH" indicating that handpiece is overheating was flashing on display; display is normally off when handpiece

Amplitude amount might not reach to the set value depending on tool to use. Handpiece may be overheated in case handpiece is in operation

is NOT in operation. Error may occur if activating handpiece even though it is overheating.

is deactivating.

・Select STROKE CONTROL mode in normal use.

If occurred above, decrease amplitude amount or use VOLTAGE CONTROL to make number of LEVEL meter when handpiece is deactivating less number

・Select VOLTAGE MODE in case stable vibration with light and constant load is desired.

of LEVEL meter when handpiece is activating. Do not turn the POWER MODE on because there is a possibility to further increase overheating of（６）Set amplitude amount or drive voltage of handpiece by power control knob.
（７）Handpiece will start running by pressing the hand switch or the ULTRA SONIC On/Off Switch on the powerpack.
（８）Press hand switch or the ULTRA SONIC On/Off Switch on the powerpack again to stop the running Handpiece.
※In case errors occur, press the hand switch or the ULTRA SONIC On/Off Switch on the powerpack and then the errors will be canceled.
If the errors of the 90s occur, turn the main switch off to cancel.

handpiece. If handpiece was overheated by the POWER MODE, turn the POWER MODE off.

●VOLTAGE CONTROL
Handpiece is activated by constant drive voltage.
Amplitude amount of handpiece is decreased by loading due to the constant voltage; because vibration is stablecomparing STROKE CONTROL, it is suitable to use for light-load work such as mirror finishing and fine finishing.
Amplitude amount is excessive when all LED lights are on in operation of handpiece. Voltage will be suppressed byprotective function. Protective function will be activated to suppress working voltage.

With Foot Switch（１）Put the foot switch plug into the foot switch socket on the back.
※An error occurs if plug in and out while the main switch is on.In order to cancel the error, turn the main switch off.

（２）Follow the same procedures form（１）～（６）of "without Foot Switch".
（３）Motor will start running by pressing foot switch.
（４）In order to stop the handpiece, turn the foot switch off.
※In case that errors occur due to overload or something, turn the foot switch off and the errors are canceled.
If the errors of the 90s occur, turn the main switch off to cancel.

＜With FS201＞
Aamplitude amount or drive voltage are adjusted by power control knob.

７.

Confirmation Method for Vibration Condition of Handpiece（１）Remove the mounted SENTAN TOOL on handpiece.
（２）Press DRIVE MODE switch to set VOLTAGE CONTROL.
（３）Adjust power control knob to the position as lighting 3 lamps of LEVEL meter.
（４）Activate handpiece.
＜What to Check＞
１．Confirm if value from 28 to 31of vibration frequency was indicated on display.
２．Confirm if all lights of LEVEL meter could be on.

Caution

7■Ask for repair if ALL of the above were NOT confirmed.
■Confirm above when temperature of handpiece is in range from 0 to 40℃.

Trouble Shooting■In case that errors occur, the error information will be displayed on the front panel.
■This information is provided first by「E.-」showing error occurrence. Then, simple displays such as「OL」(Overload)
appear on the front panel for its cause of the error. These information are alternately displayed.
■Pressing and holding the DRIVE MODE switch during the error displays「E.-」and error No. alternately.
■In case errors occur, press the hand switch or the ULTRA SONIC On/Off Switch on the powerpack and then the errors
will be canceled.
When using a foot switch, turn the foot switch off to cancel the error.
If the errors of the 90s occur, turn the main switch off to cancel.
