5. Operation

5.1

Switching on / off

The unit is switched on and off via the sensor surface (9).
⇒ To switch the unit on, touch the sensor surface (9) with the palm
of your hand for 1 second. Do not apply pressure.
♦ The operating display (3) lights up.
♦ The target laser (1) lights up.
The drilling motor is activated when the drilling table (2) depressed.
Only activate the drilling motor when there is a drill in place!

5.1.1 Auto Off

The unit includes an automatic switch off function. If the unit is not
used for a duration of 3 minutes, it automatically switches off.
5.2

Setting the Drilling Depth

The drilling depth can be set at the adjustable depth
stop (12) underneath the drilling table. If necessary,
carry out trial drillings.
The symbols on the drilling table indicate the direction
of rotation:
A: shorter drilling hole
B: deeper drilling hole
The drilling depth changes approximately 0.1 mm
for each click on the depth stop.
5.3

Drilling

⇒ Place the dental arch onto the drilling table (2, Fig. 1) and align the target laser (1, Fg. 1).
⇒ Hold the dental arch with both hands.
⇒ Press the drilling table down as far as it will go.
♦ The motor will be activated automatically and begin drilling from the bottom of the dental arch.
⇒ Guide the drilling table back up.
♦ The motor will stop when the drilling table has reached its original position.

5.3.1 Using the Marking Rings

Next to the target laser there are marking rings (20) on the table surface,
to act as a guide, so that the drill holes can be placed more precisely. If the
dental arch is very narrow or if the teeth are extremely close together, it is very
difficult to maintain the minimum distance between the individual pins and the
dental arch edge.
Recommended approach:
⇒ Align the edge of the dental arch with the edge of the drilling hole (Fig. 6.1).
⇒ Start the first drill hole.
♦ With a 2 mm drill hole there will be a distance of 2 mm to the outer edge of
the dental arch, (with a 1.6 mm drill there will be 2.2 mm distance).
⇒ Push the dental arch to the outer edge of the first marking ring (Fig. 6.2).
⇒ Start the second drill hole.
♦ This will then create a distance of 3 mm between the drilling holes.
