Methods of use
01
Press the power button of the main body for 1 to 2 seconds to turn the LED
on the face panel on. This turns the product into stand-by state.
(another push will turn the power button off.)
* The LED(green) on the handle is off.
02
Pull the handle out inside the main body.
03
At stand-by state, press the power button on the handle. This will cause
40,000 vibrations per second. The cutter only operates while being pressed.
* The LED(green) on the handle is on.
04
When used for more than 10 minutes, the product stops operating and goes into
stand-by state.
* The LED(green) on the handle is off under stand-by state. The inner temperature of the
handle gets higher while being used, turning into high temperature stationary state.
* The LED button of the handle does not turn on in high temperature stationary state.
* The stand-by state extends based on the handle power button.
* When the main body is on, the vibrating part continually creates sound waves so
the product must be turned off when not in use. In order to prevent putting the
handle into the main body unconsciously, the product is designed to beep.
Methods of use
04
Stand-by
The LED turns green when the main body is turned on.
The remaining battery can be checked on the LED of face panel.
* The LED(green) on the handle is off.
* The product turns off automatically after a beep when not used for more
than 10 minutes in the stand-by status.
Up and Running
Vibrations on (pressing the handle button)
* The LED(green) on the handle is on.
Stand-by after buzzer sound
The continuous production of 40,000 vibrations per second generates high
temperature vibration, and protective function is activated as the circuit is overload.
* The power button on the switch cannot be operated.
* The LED(green) button does not turn on.
* Loose setscrew of the blade or overload on the blade produces such situation.
* This does not turn into normal operation status by its own. Turn the power
off and tighten the setscrew before restarting the device.
High temperature stationary state
The product enters high temperature status after being used for 10 minutes.
The protective function turns the product into stand-by when in high temperature.
* When the temperature drops to a certain level, the LED(green) turns on.
