Electric Motor Speed Set Switch (Optional) (Fig.3-12)
Two different modes, limit mode and preset mode, are available as
micromotor rotation speed modes. Pressing this switch each time changes
the speed mode: Limit speed -> SET1 -> SET2 -> SET3 -> Limit speed.
The indicator indicates the selected mode.
1) Switching to limit rotation speed (limit mode)
Pick up the micromotor from the holder, and press this switch to select limit mode. For selecting the upper
limit in the limit mode, press either plus switch or minus switch. The upper limit of the micromotor rotation
speed changes in three steps (or 5 steps).
- Upper limit of rotation speed in case of 3 steps: 10000/20000/40000 min
-1
(rpm)
- Upper limit of rotation speed in case of 5 steps: 5000/10000/20000/30000/40000 min
-1
(rpm)
See item g. on page 13 for setting in 5 steps.
The micromotor rotation speed can be varied in the range of up to the selected upper limit by sliding the
foot controller pedal right or left. The rotation speed range varies by the micromotor type.
2) Switching to preset rotation speed (preset mode)
Pick up the micromotor out of the holder, press this switch, and then select preset mode (SET1 to 3).
The rotation speed in this mode can be changed by pressing plus switch or minus switch. Press store switch
for storing the changed rotation speed.When the foot controller is depressed upon selection of preset mode
(SET1 to 3), the micromotor runs at the fixed rotation speed indicated on the indicator
.

Coolant Water ON/OFF Switch (Fig.3-11)
When a handpiece is picked up and this switch is pressed, both LED A (air)
and LED W (water) lights up, the coolant water and air comes out from the
handpiece. In case of air motor or air turbine, switching between spray (both
of LED A and LED W are lit) and OFF occurs when this switch is pressed.
In case of electric scaler, switching between water only (LED W is lit) and
OFF occurs when this switch is pressed, regardless of the mode.
In case of micromotor, either the 2-mode or the 4-mode can be selected by
mode select setup.When this switch is pressed in the 2-mode setup, switching
between spray and OFF occurs. In case of 4-mode setup, switching occurs in
the sequence indicated below each time when this switch is pressed: Spray to
Water only to Air only to OFF.
As for the mode setting, Please refer to 3-1.(3) h.
