Before you switch the unit on, you must set the rotating speed (rotary knob (D))
to zero.
A. Insert the power adapter (A) into the power socket and the power adapter plug (B), on the
back of the device, into the provided power adapter socket (C).
B. Insert the plug of the handpiece into the socket (I) on the right side of the device.
C. Select a suitable grinding head. Insert the abrasive wheel in the front on the hand piece
into the abrasive wheel mount (K) and lock the collet.Never use force to remove or insert
a grinding head! Grinding heads with a shaft diameter of 2.332 mm to 2.350 mm (0.091
to 0.093 inches) fit exactly into the grinding head holder without you having to use excessive
force. To remove a grinding head, switch off the device with the rotation switch (D) (middle
position), making sure that the rotation switch (D) clearly locks into place. Now remove the
abrasive wheel after opening the collet.
D. Control of the rotation direction and speed:
1. Selection of the rotation direction:
You make this selection by turning the rotation switch (D) to the left or right.
Counterclockwise: The abrasive wheel turns to the left.
Clockwise: The abrasive wheel turns to the right.
2. Choice of rotational speed:
The speed is regulated by turning the rotation switch (D) to the left or to the right. The more you
turn, the higher the rotationspeed.
3. Rotational speed indicator:
The rotational speed indicator (E) is on the left next to the rotational speed regulator/
rotational direction regulator (D). This indicates the selected rotational speed by means of
5 LEDs. The device functions with maximum rotational speed when all LEDs light up.
E. Before the first use, make sure that you let the handpiece run for about 30 minutes at approx.
16.000 rpm (2 LED lights of the speed indicator (E) should flash). This is necessary to bed in the
carbon brushes of the motor.
F. Use of foot pedal (optional accessory):
Set the rotational speed regulator (D) on "zero" (middle position). Connect the foot pedal
(O) to the socket (H). The foot pedal LED (F) lights up yellow if the foot pedal is correctly
connected. The running direction and rotational speed are set by turning the rotational
speed regulator/rotational direction regulator (D). The device is now in standby mode.
Turn the device on by pressing the foot pedal. The abrasive wheel starts to rotate in the
direction and rotational speed you selected. You switch into the standby mode by pressing
the foot pedal again.
Attention:
Never connect the foot pedal (O) to the station or remove this from the station while an
abrasive wheel is turning in the hand piece. The device switches itself off in the event of
non-compliance (SAFETY STOP). The rotational speed regulator (D) must absolutely be set
at "zero" (middle position) to plug in or remove the foot pedal.
Note:
Only Promed foot pedals can be used.
