Make sure the appropriate voltage (110V or 220V) is selected by setting the switch at the back of the transformer.
Plug in the electric cord of the transformer to the main electric outlet. The lamp on the transformer will turn on.
Connect the end of the cord from the handpiece to the front output hole on the transformer.
Turn on the on/off switch on the transformer (machine should be at the lowest speed when turning on).
Select the desired speed by turning the variable speed control knob on the transformer.
The black switch in front of the transformer, next to the speed control selection knob is for switching the rotation direction – forward (clockwise) or reverse (counter-clockwise).
To use the foot pedal control, connect the end of the cord from the foot pedal to the out put hole at the back of the transformer and press down on the foot pedal.
To secure the bits: push the desired bit firmly into the hole at the rotating head of the hand piece until the second lock clicks. (Please note the bit has to pass through two clicks (locks) before it is firmly secured.)
To remove the bits, turn off the machine and gently pull the bit out.
