CAUTION

• When operating the handpiece always consider the safety of the patient.

• Check for vibration, noise and overheating outside the patient's oral cavity before use. If any abnormalities are found, stop using the handpiece

immediately and contact dealer.

• Should the handpiece function abnormally, cease operation immediately and return the handpiece to an authorized dealer for repair.

• Depressing the push-button while the handpiece is rotating will result in OVERHEATING of the handpiece head. Special caution must be exercised

during use to keep cheek tissue AWAY from the push-button of the handpiece. Contact with cheek tissue may cause the push-button to depress and

burn injury to the patient may occur.

• Do not applying excessive power in the direction which bur removes. When the bur drops into patient’s oral cavity, they may drink by mistake and get

injured.

• This handpiece have built-in dynamo. Consumption Air generates electricity and LED become luminous. Therefore, do not perform autoclave

sterilization which it heat and cools rapidly.

• Do not allow any impact on to the Handpiece. Do not drop the Handpiece.

• Do not look into LED light directly.

CAUTION

• Ensure connect “Coupling and Hose” or “Handpiece and Coupling” ﬁrmly.

• Do not pull the Connector Ring while the handpiece is under air pressure. It may jump the handpiece out from the connector because of the

air pressure.

• Do not exceed the recommended air pressure. If it exceeds the pressure, it may bur jump out from the handpiece.

• Ensure clean, dry air supply. Moisture and debris in air supply may cause the motor to malfunction.

CAUTION

• Do not connect or disconnect the handpiece or bur until the motor has completely stopped.

• When used for crown removal and other procedures that would involve heavy vibration, the bur may become difﬁcult to remove. Push the

button ﬁrmly, and forcibly pull out the bur with a pair of pliers. Apply small amount of spray lubricant into the chuck. This can be prevented if

the bur is repositioned a few times during the procedure.

• When abnormalities are in LED (dark, do not light on or ﬂashing or so), contact dealer to repair.

• Do not attempt to disassemble the handpiece or tamper with the mechanism except NSK recommend on this Operation Manual.

• Always keep bur shanks clean. Dirt or debris in a chuck could cause poor bur concentricity or low chuck retention force.

• Do not exceed the drive motor speed recommended the bur manufacturers. If the rotary speed which the manufacturer of bur nominates is lower than

spec of handpiece, do not use it.

• Do not connect or disconnect the handpiece or bur until the motor has completely stopped.

• NSK has not recommended the repair and disassembly of the cartridge without exception. Handpiece may perform abnormally (abnormal noise or

abnormal vibration). Damage, failure or accidents are outside of our guarantee.

• Do not wipe with, or clean or immerse in, high acid water or sterilizing solutions.

• Use eye protectors, mask for safety when operating this handpiece.

• User is responsible for operation, maintenance and safety.

• If the handpiece has not been used for a long period, check for noise, vibration, and overheating before use.

• Treatment under the sufﬁcient irrigation water(Spraying water).

1. Specification

Intended to use:

This handpiece is designed only for clinical dental use by qualiﬁed personnel.

3. Check before treatment

Follow the check below, before use. If any abnormalities are found, stop using the handpiece immediately and contact the authorized NSK dealer.

1) Insert the Bur. (Do not exceed maximum rotation speed for any item.)

2) Check that there is no abnormal rotation, vibration, noise and overheating.

3) If there are no immediate apparent abnormalities, continue to rotate the handpiece for about 1 minute. Then check that there is no abnormal

heating on the outer surface.

4) Operate it if there are not abnormalities above.

CAUTION

• Do not use non-standard burs. The ISO standard shank diameter is

1.59 -

1.60 mm.

• Do not exceed the bur speed recommended by the bur manufacturer. Moreover, do not use the bur which it has lower rotation speed.

• Do not use long surgical burs. Do not use burs longer than 26mm.

• Do not use short shank burs.

(

M600LG B2

M600LG QD

)

• Always keep the bur shank clean. Entry of hard debris into the chuck via the bur shank could cause rotation slip and also prevent the bur from

being securely located in the chuck.

• Fully depress the Push Button and insert the bur into the chuck until it is secure.

• Test that the bur is secure by gently pulling and pushing the bur without depressing the Push Button.

4. Insertion /Removal of the Bur

CAUTION

• Be sure to hold the handpiece ﬁrmly to prevent the handpiece from slipping out of hand by the spray pressure when lubricating.

• Supply lubricant until it comes out of the handpiece head.(at least 2 seconds)

• Hold the spray can upright.

9. Non-Retraction Valve (QD Coupling)

To prevent oral ﬂuids drawn into the water line, QD coupling has Non-Retraction valve. If water is

beginning to leaking from handpiece, replace non-retraction valve.

1) Remove the back-end gasket.

2) Replace Non-Retraction Valve.

10. Warranty

NSK warrants our product against poor manufacturing, poor workmanship and defects in materials. NSK reserves the right to analyze and determine

the cause of any problem. Warranty is voided should the handpiece be not used correctly. Replacement parts are available for seven years beyond

discontinuation of the model.

CAUTION

• To prevent infectiveness, Autoclave the handpiece every patient.

• Do not autoclave the handpiece, even when it is bagged, together with other instruments, from which chemicals are not sufﬁciently cleaned.

This is to avoid discoloration and/or damage to the plating of the handpiece.

• In case the sterilizer chamber temperature could exceed 135°C during the dry cycle, skip the dry cycle.

• Do not heat or cool the handpiece quickly. Rapid change in temperature could break the glass rod or dynamo or LED parts.

6. Changing Turbine Cartridge

1) Mount a dummy bur in the chuck.

2) Turn the Wrench counter clockwise and remove the Head Cap by Head Cap Wrench.

3) Push up the dummy bur to remove Cartridge.

4) Clean the head interior. (Wipe extra oil after lubrication)

5) Align the Alignment Pin and insert Cartridge. (Fig. 8)

6) Turn the Wrench clockwise and mount the Head Cap. (Fig. 9)

* Replacement Cartridge: SX-MU03 Mini Cartridge Order Code P1001250

SX-SU03 Standard Cartridge Order Code P1002250

2) Take out the cleaning wire from the back end of the brush holder. Insert the wire straight into the spray ports with caution. Do not forcibly insert the

wire into the port. Damaged or disoriented port could cause the spray diverge or directed away from the bur, and the cooling efﬁciency deteriorates.

3) After use, clean the cleaning wire. Push into the brush holder with the pointed end of the wire inward.

．

Spray Port Cleaning

When spray port are clogged, or spray does not exit evenly from three ports, clean the ports as follows:

1) Remove the bur from the chuck. (Refer to “4. Insertion/Removal the Bur” and “6.

Replacing the Cartridge”)

8. Replacing the O-rings (QD Coupling)

Worn or damaged O-ring may cause air or water to leak.

When water is found in the exhaust air or water leak from the coupled point, replace four O-rings as shown in Fig.10.

CAUTION

Do not use a pointed tool or sharp edged to clean the Cellular Glass Optic Rod. They may damage the mirror ﬁnish and reduce the light

transmission efﬁciency. If Cellular Glass Optic Rod end has become damaged, return it to dealer for repair.

5-3 Cleaning

Scrub dirt and debris from the handpiece, and wipe clean with alcohol-immersed cotton swab or cloth. Do not

use a wire brush.

* Refer the manual of Thermo-Disinfector for performing it.

This handpiece can be washed via Thermo Disinfector.

5-2 Cleaning (Glass Rod)

Wipe clean the Cellular Glass Optic Rod entry point and exit point with an alcohol-immersed cotton swab. Remove all debris and oil.(Fig.6)

CAUTION

• Tighten the head cap after changing the cartridge. If attachment is loose, there are the causes of an injury in

oral cavity or possibility of accidental ingestion.

• Use only NSK purity cartridge. Competitive cartridge is not covered under warranty.

• The screw of head cap is very small. Do not bind tight using a Wrench from the start. After tightening by the

hand, use the Wrench.

• Check that the O-Rings are placed correct position and then install the cartridge.(Fig.10)
