Your safety, the safety of your team, and of course that of your patients is very important to us. It is there-
for essential to bear the following information in mind:
Every use of the MD 30 different to the product description defined in chapter “Intended use and opera-
tion”, causes risks for patients and trained personnel. If physical examinations and therapies are carried out
without use of the devices then the devices must be removed from the place of treatment. Avoid any con-
nection or close adjacency to other devices.
3.1 EMC Manufacturer’s Declaration of Conformity
The use of (RF) Radio Frequency emitting devices and equipment as well as the occurrence of negative envi-
ronmental factors in the close area of the MD 30 may cause unexpected or adverse operation. The connec-
tion or the placing of other devices in close vicinity is not allowed.
The Product is suitable for use in establishments of the industrial sector and hospitals. When used in the
domestic establishments, this unit may not provide adequate protection for radio services. The user must
take remedial measures such as implementation or reorientation of the product.
Use only accessories and cables as specified in the product description. Further observe the EMC manufac-
turer declaration of conformity.

3.3 Modification and misuse
3.4 Essential requirements
The use of third-party products is the
responsibility of the operator. Functionali-
ty and patient safety cannot be guaran-
teed with third-party accessories.
Improper use or repair of the device and failure to
observe these instructions relieve us from any obli-
gation arising from warranty provisions or other
claims.
Only use the NouvaClean spray (REF 2127)
for the internal cleaning of handpieces
and contra-angles. The use of other clean-
ing products can lead to malfunctions and
the warranty becomes void!
Only use the NouvaOil spray (REF 2128) to lubricate
electronic motors, handpieces and contra-angles.
The use of other care products can lead to malfunc-
tions. The warranty becomes void!
Repairs may only be performed by author-
ized NOUVAG service technicians.
The MD 30 may only be operated by qualified and
trained personnel.
Prior to using the device, before startup, and before operation, the user must always ensure that the de-
vice and accessories are in good working order and are clean, sterile and operational.
3.5 During use
The device is not sterile on delivery. All
sterilizable parts must be sterilized before
use (see Chapter 8.0 Cleaning, disinfec-
tion and sterilization).
Never operate the clamping mechanism of the
handpieces or contra angles while the system is
running. This could result in instrument damage.
Handpieces and contra angles may only
be attached when the electronic motor is
not running.
To prevent injury, never touch drill bits or burrs
while they are still running.
At the choosing of the instrument the
operator has to make sure it’s biocompat-
ible, according to EN ISO 10993.
Do not use the device, pedal and motor in the vicin-
ity of flammable mixtures!
At operation at a patient, make sure to produce as less as possible friction heat. By excessive thermal
influence on the tissue, the tissue easily gets necrotized. The heat generation is directly proportional to
the speed delivery of the instrument and the contact pressure delivered by the instrument.
Modification or manipulation of the MD 30 and its accessories is prohibited. The manufacturer is not
liable for any damages resulting from unauthorized modifications or manipulations. The warranty is no
longer valid.
Use of the MD 30 outside the indications described in Section 1.1 is prohibited. The user or operator is
solely responsible for any such use.

6.3 Device preparation
1. Sterilize the motor (the motor is not sterile on delivery). If the motor has already been sterilized: when
removing the motor from the sterile packaging, ensure that the sterile packaging is not damaged and
that the sterility indicator confirms sterility (if no sterility indicator is provided, the sterile packaging
must at least show the date on which the shelf life of the sterile item is due to expire).
2. Insert the stand for the irrigation fluid into the stand holder.
3. Plug the motor plug of the electronic motor into one of the motor sockets.
4. Where appropriate, plug the motor plug of a second electronic motor into a motor socket.
5. Plug the pedal plug into the pedal socket at the rear of the control unit.
6. Attach the sterilized handpiece to the electronic motor. Press the handpiece firmly onto the electronic
motor until it clicks into position and make sure it is secure by moving it slightly in the opposite direc-
tion.
7. Assemble the tubing set: Decide whether you will use tubing set REF 1706, for the cooling of a single
contra angle or if you need to use tubing set REF 6025 with an integrated 3 way tap for the cooling of
both contra angles during a procedure, while both motors are plugged in.
Use only Nouvag tube sets REF 1706 and 6025, otherwise the correct function cannot be guaranteed.
A) Press release key for tubing set bracket (on top of the control unit) to open the pump.
B) The compartment with the integrated tubing bracket opens.
C) Place the tubing set into the tubing bracket provided in such a way that the part of the tubing set
with the spike exits the pump towards the rear of the device. Make sure the tubing is secure.
D) With the tubing set inserted, press the compartment downwards until it clicks into place.
Check the expiry date of the tubing set and ensure that the packaging is not damaged. Using
non-sterile tubing sets can result in serious infection and, in extreme cases, can be fatal.
When inserting the tubing set, watch the arrow on the cover of the pump compartment.
It indicates the flow direction of the cooling liquid.
Do not regulate the amount of irrigation fluid using the roller clamp on the tubing set; with the MD 30, this
is regulated instead using the integrated pump. For this reason, make sure to open the roller clamp as far
as it will go (please refer to 7.4.5 Setting the pump supply quantity).
The integrated peristaltic pump is used to cool the tissue and thus to avoid tissue damage. It may only be
operated with aqueous solutions, such as sterile 0.9% NaCl rinsing solution or Ringer’s solution. The deliv-
ery of drugs with the integrated pump is expressly prohibited.

7.4.2 Step 2: Calibrating handpieces
To make sure the displayed parameters correspond with the actual, measurable parameters of the hand-
piece or contra angle, it is recommended to calibrate each handpiece or contra angle on a regular basis.
It’s a procedure as simple as it is important to guarantee safety and precision of each handpiece or contra
angle being used.
After you take care of all prior preparations such as sterilization, maintenance and care of handpieces, de-
vice preparation and the selection of the handpiece of use, the calibration procedure can be performed.
The calibration of handpieces or contra angles guarantees accurate torque. Due to wear as well as varying
lubrication of the handpieces or contra angles, and lack of maintenance and care, the distribution of
torque can vary widely.
1. Hold motor with mounted handpiece or contra angle in your hand at safe distance from your body.
2. Press both «Speed» - keys at the same time (Speed ▲+ ▼).
3. Motor and handpiece start running and pass several speed cycles up to maximum speed.
4. After a tone is emitted and a message is displayed the calibration is finished.
If a handpiece is not working within the range of the calibration algorithms, even when it was cleaned and
lubricated before, the display shows an error with a red backlit display, „Handpiece XX is faulty“.
This indicates soiling, wear or a technical defect of the handpiece. These handpieces have to undergo a
maintenance and care cycle or have to be repaired or replaced.
7.4.3 Step 3: Setting the speed
The possible speed range depends on the attached handpiece or contra angle. The maximum speed within
this speed range can be restricted to the required value.
Using the pedal, the speed can be varied from the minimum speed up to the maximum speed as set.
Setting the speed:
Press the «Speed» keys “▲”to increase or “▼”to decrease the maximum speed. When key is pressed con-
stantly the speeds will be shown in fast forward mode.
At the calibration procedure, the handpieces are tested on their torque delivery behavior. With the follow-
ing contra angles (4:1, 16:1, 20:1, 32:1, 70:1) the control unit is additionally adjusted to altered conditions of
the contra angle to keep it delivering the appropriate torque.

The following handpieces run only with one specific speed, it cannot be changed. The specific rpm val-
ues of all handpieces are shown in the table of chapter 7.4.1.
●Micro saws (Micro Compass Saw MSS 5000, Micro Oscillating Saw OMS 5000, Micro Sagittal Saw
MOS 5000)
●Mucotome
7.4.4 Step 4: Setting the torque
Once the speed has been selected, the torque can be determined from the corresponding torque range.
Depending on the speed, the torque mode AL or AS is applied.
For information on AL and AS mode, see Chapter “7.5 Speed reduction AL (Automatic Limiter)” and Chap-
ter “7.6 Torque limit function: AS (Automatic Stopper)”
Press the “Torque” keys “” to increase or “” to decrease the maximum torque. By pressing the key con-
tinuously the torques are shown in fast forward mode.
The following handpieces run on fixed torque only (6 Ncm) and cannot be changed.
●Micro saws ●Mucotome
●Kirschner Handpiece
7.4.5 Step 5: Setting the pump supply quantity
Press the “Pump” keys “” to increase or “” to decrease the pump supply quantity. By pressing the key
continuously the values are fast forwarded.
Minimum und maximum of pump supply quantity as well as operating steps can be adjusted in the Configu-
ration Menu (refer to «7.8 Configuration Menu, Parameter level 2, Pump»).
To activate or deactivate the pump, press both “Pump” keys at the same time,
“Pump + ”, or use the foot switch .
The build up of torque is displayed
as a bar graph. When maximum
torque is reached all elements of
the bar graph are full displayed.

7.5 The function of the torque limiter, AL mode (Automatic Limiter)
The AL function limits the torque applied to the instrument, for example to prevent crack initiation and
bone fracture.
The speed at the instrument remains constant until the preset torque is reached. If the applied force gets
over this limit the speed will be reduced, if necessary down to a stop, but the torque remains constant. If
the applied force is reduced the speed picks up again.
On the display this procedure is shown as a bar graph. The bars in the graph fill up to their full range as the
torque increases to its preset value. When the bar graph shows full capacity the speed will be reduced. As
soon as the force on the instrument is reduced the torque decreases and the speed starts to pick up again
as shown on the display.
The AL mode is active at all speeds, except at the speeds where the AS mode takes effect.
7.6 Torque limit function, AS mode (Automatic Stopper)
The AS function limits the torque applied to the instrument. As soon as the preconfigured torque is
reached, the electronic motor stops immediately. The electronic motor no longer generates any force. In
order to restart the electronic motor, the treadplate must be released and pressed again.
On the display, the bar graph completes up to its full range, until the maximum torque is reached, then
drops to zero.
The function “AS” is just active for certain contra angles
and only in a certain speed range.
From the minimal speed up to the speeds shown at the
right the AS-mode is activated automatically.
(refer to “7.8 Configuration Menu, Parameter level 2, AS-Zone”)
The upper limit of the AS range can be adjusted in the configuration menu.
In the following speed ranges the AS-/AL-mode
can also be switched manually by pressing both
torque keys “Torque +” at the same time.

7.7 Storing various programs
With the MD 30, up to 10 different settings can be set per motor as fixed program (program 1 to program
10). Which program is currently active is shown on the display.
At the switch-off of the device, the settings made by the user are automatically saved. This includes the fol-
lowing parameters:
• Handpiece/Transmission ratio
• Maximal speed
• Maximal torque
• Pump On/Off
• Pump performance
• AS/AL mode
To change a program go to the specific parameter and change it. When the device is switched off all param-
eters are saved in that program.
The number of storable programs can be limited in the configuration menu from 3 to 10 programs.
When the MD 30 is switched on, the display shows the prior used program with the last used Handpiece
respectively Contra angle.
