A. GROUNDING INSTRUCTIONS
Grounding Method
1. In the event of a malfunction or breakdown, grounding provides a path of least resistance for
electric current to reduce the risk of electric shock. This tool is equipped with an electric cord
having an equipment-grounding conductor and a grounding plug. The plug must be plugged
into a matching outlet that is properly installed and grounded in accordance with all local
codes and ordinances.
2. Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by
a qualified electrician.
3. Improper connection of the equipment-grounding conductor can result in a risk of electric
shock. The conductor with insulation having an outer surface that is green with or without
yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric
cord or plug is necessary, do not connect the equipment grounding conductor to a live
terminal.
4. Check with a qualified electrician or service personnel if the grounding instructions are not
completely.
Understood, or if in doubt as to whether the tool is properly grounded.
5. Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles

illustrated in Sketches B and C, may be used to connect this plug to a 2-pole receptacle as
shown in Sketch B if a properly grounded outlet is not available. The temporary adapter
should be used only until a properly grounded outlet can be installed by a qualified
electrician. The green-colored rigid ear, lug, and the like, extending from the adapter must be
connected to a permanent ground such as a properly grounded outlet box.

7. USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one heavy enough to carry the current your
product will draw. An undersized cord will cause a drop in line voltage resulting in loss of
power and overheating. Table (below) shows the correct size to use depending on cord
length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the
gauge number, the heavier the cord.
8. Install equipment so that the power supply cord can be pulled out without hindrance in event
of emergency. Do not place anything within 10 centimeters around the unit.

6. Memory Function
When the main switch is turned on, the rotation direction and the Motor/Turbine selections
made when the main switch was last turned off are restored. Special attention should be given
to the rotation direction.
7. When Abnormal Conditions Occur
When problems connected with the motor or unit occurs, the power supply to the motor will
stop and the power indicator flashes. Unlike being stopped by the protection circuit, the motor
will not start even when the pedal is depressed. If such a problem occurs, please ask for repair
service.
On some dental tables with vacuum dust collector, the motor may be used while being coupled
with a dust collector. When such a dust collector * is used, power consumption of ULTIMATE
XL-F can be regulated so that the vacuum-coupled function can work. If you need coupling
with a vacuum dust collector, select the mode as follows:
How to select the mode
While pressing Forward / Reverse Selector Switch, turn on Main Switch, and the mode
can be selected. A long beep indicates vacuum-coupled mode and 2 short beeps indicate
non-coupled (energy-saving) mode.
* Each time the switch selection is made, the mode changes between vacuum-coupled mode
and non-coupled mode.
* A currently known dust collector is KAVO EWL-560.
8. Replacement of Fuse
9. Vacuum-coupled Mode

primary current source. If the cause is uncertain, return the product to an authorized
NSK's service shop for inspection.
CAUTION

English
If a bur having a large diameter of a cutting
part is used under a high torque, the chuck
may rotate in the close direction and the bur
may be stuck and cannot be removed. In this
case, align the nose's slit and spindle's
spanner position (flat part), and apply an L
spanner to fix the spindle. Open the ring and
turn the chuck counterclockwise with the
provided spanner wrench to remove it. (Fig.8)

A. ERDUNGSANWEISUNGEN
1. Im Falle einer Fehlfunktion oder eines Ausfalls bietet die Erdung einen Weg des geringsten
Widerstands für den elektrischen Strom, um die Gefahr eines Stromschlags zu reduzieren.
Dieses Gerät ist mit einem Stromkabel ausgestattet, das einen Erdungsleiter und einen
geerdeten Stecker besitzt. Der Stecker muss in eine passende Steckdose gesteckt werden,
die korrekt installiert und entsprechend aller geltenden Vorschriften geerdet ist.
2. Den mitgelieferten Stecker nicht verändern – wenn er nicht in die Steckdose passt, lassen Sie
die richtige Steckdose von einem qualifizierten Elektriker installieren.
3. Unsachgemäßer Anschluss des Erdungsleiters kann zur Gefahr eines Stromschlags führen.
Der Leiter mit einer grünen oder grün-gelb gestreiften Isolierung ist der Erdungsleiter. Wenn
eine Reparatur oder ein Austausch von Stromkabel oder Stecker erforderlich ist, den
Erdungsleiter nicht an einen stromführenden Pol anschließen.
4. Überprüfen Sie die korrekte Erdung des Geräts zusammen mit einem qualifizierten Techniker
oder Kundendienstmonteur, wenn Sie die Erdungsanweisungen nicht vollständig verstanden
haben oder im Zweifel darüber sind.
5. Nur dreiadrige Verlängerungskabel verwenden, die dreizinkige Erdungsstecker und die
richtigen Buchsen für den Stecker des Geräts haben.
6. Dieses Gerät ist zur Verwendung an einem Stromkreis vorgesehen, der eine Steckdose wie in
Zeichnung A (unten) besitzt (120 V). Das Gerät besitzt einen Stecker wie in Zeichnung A
(unten). Ein provisorischer Adapter, wie unten in den Zeichnungen B und C dargestellt, kann
verwendet werden, um diesen Stecker mit einer zweipoligen Dose zu verbinden, wie in
Zeichnung B zu sehen, wenn keine korrekt geerdete Steckdose zur Verfügung steht. Der
provisorische Adapter sollte nur so lange verwendet werden, bis eine korrekt geerdete
Steckdose von einem qualifizierten Elektriker installiert werden kann. Das grüne, starre Öhr,
der Zapfen und andere Vorsprünge des Adapters müssen an eine permanente Erdung wie
beispielsweise eine korrekt geerdete Steckdose angeschlossen werden.
Bei der Verwendung elektrischer Geräte sollten stets einige grundsätzliche
Vorsichtsmaßnahmen befolgt werden, um die Gefahr von Feuer, Stromschlag und eigenen
Verletzungen zu reduzieren. Dazu gehören die nachfolgenden Maßnahmen. Lesen Sie alle
diese Anweisungen vor dem Betrieb dieses Produkts durch und bewahren Sie sie auf.
