NOTICE

Ř Grip the handpiece while placing your thumb tip on the Push button which makes it easier to depress the button.

CAUTION

Ř Always insert the bur all the way into the chuck.
Ř Remove the bur only after the handpiece has completely stopped rotating.
Ř Always keep the bur shank clean.
Ř Entry of debris into the chuck, via the bur shank, could cause bur rotation slip and also prevent the bur from being securely located in the

chuck.

Ř Do not exceed the bur speed recommended by the bur manufacturer.
Ř Do not exceed maximum bur length recommended by the handpiece manufacturer.
Ř Do not apply excess pressure to the bur as it may break or bend or become difficult to remove.
Ř DO NOT use burs with problems listed below as the bur may break, seize up or disengage from the chuck.

- Bent, deformed, anisomerous (worn), rusted, broken, deficient bur.

- Bur which is cracked on the edge or axis.

- Non-ISO standard, or tampered bur.

8. Maintenance

After each patient maintain the product as follows. Lack of maintenance could cause premature failure or
overheating of the handpiece.

Clean Head Hole

8-1 Cleaning handpieces with the NSK Clean-Head System

After the treatment of each patient, clean the Clean Head.

1) Half fill a cup with clean water.

2) Remove dirt and debris from the Clean Head Holes with the cleaning wire and brush (supplied as an
accessory for the handpiece) (Fig. 5).

3) Rotate the handpiece and immerse half of the handpiece head in the cup of water (Fig. 6).

4) Rotate then stop intermittently the handpiece 3 times for 2 to 3 seconds each time.

5) Wipe the handpiece dry.

* If the dirt could not be removed from the hole, clean it by brush.

8-2 Cleaning (Handpiece)

1) Remove debris from the product. Do NOT use a wire brush.

2) Wipe clean with alcohol-immersed cotton swab or cloth.

This icon denotes that the product can be washed via Thermo Disinfector.

Refer to the Thermo-Disinfector manual.

CAUTION

Ř After washing with Thermo-Disinfector and prior to lubrication, dry the product until all internal moisture is thoroughly removed. Thermo-

Disinfector moisture remaining inside the product could reduce the effect of lubrication and could cause corrosion inside of the product.

Ř To clean the product never use any solvent such as benzine or thinner.

8-3 Cleaning (Optic)

Wipe clean the Glass Rod tip with an alcohol-immersed cotton swab. Remove all debris and oil (Fig. 7).

CAUTION

Ř Do NOT use a sharp tool to clean the Glass Rod. It could damage the glass and reduce the light

transmission.

8-4 Cleaning (Spray Port)

When spray ports are clogged, or spray does not exit evenly from the ports, clean the ports (Fig. 8).

CAUTION

Ř Do not forcibly insert the wire into the port. Resultant port damage could cause the spray to be

directed away from the bur, and the cooling efficiency reduces.

Ř Do not blow air into the Clean Head Hole.

8-6 Sterilization

Sterilize the product by autoclave sterilization. Remove the bur after each patient and sterilize as noted below.

1) Insert into an autoclave pouch. Seal the pouch.

2) Autoclavable under the conditions below.
Autoclave for more than 20 min. at 121°C, or 15 min. at 132°C, or 3 min. at 134°C.

3) The handpiece should remain in the autoclave pouch until required for use.

CAUTION

ŘDo not autoclave the product with other instruments even when it is in a pouch. This is to prevent possible discoloration and damage to the

product from chemical residue on other instruments.

ŘKeep the product in suitable atmospheric pressure, temperature, humidity, ventilation, and sunlight. The air should be free from dust, salt and

sulphur.

ŘImmediately after use, the product should be cleaned, lubricated and sterilized. If blood remains on the external or internal surfaces it can

become clotted and cause rust.

ŘDo not heat or cool the product too quickly. Rapid change in temperature could cause damage to the product.
ŘIf the sterilizer chamber temperature may exceed 135°C during the dry cycle then delete the dry cycle.

EN DE FR ES IT PT

15

CAUTION

Ř Autoclave sterilization is recommended for the product. The validity of other sterilization methods is not confirmed.
Ř Do not touch the product immediately after autoclaving as it will be very hot and must remain in a sterile condition.

NOTICE

Ř NSK recommends Class B sterilizers as stated in EN13060.

9. Replacing the O-rings

Replace the O-rings if water is present in the exhaust air line. This is an indication of possible water leakage
within the coupling. ALWAYS change the complete set of O-rings.

1) Loosen and remove the taper ring at the rear of the handpiece (Fig. 11).

2) Gently remove each O-ring by hand (Fig. 12).

3) Insert the complete set of new O-rings in the correct grooves.

4) Firmly tighten the taper rin

* Refer to Spare Parts List to identify the correct parts.

(Z800L/Z800/Z900L/Z900)

g.

CAUTION

Ř Do not force the new replacement O-ring with excessive pressure.
Ř When inserting new O-rings, make sure they are inserted in the correct grooves.
Ř Make certain that the taper ring is firmly tightened. If the taper ring is loose water and air leakage

could occur.

10. Replacing the Non-Retraction Valve

A water Non-Retraction Valve is integrated in the Coupling Joint, which shuts off the water retraction directly at the handpiece head to prevent fluids
infiltrating the water line. If water is beginning to leak from the handpiece, replace the non-retraction valve.

NSK Coupling (Z800L/Z800/Z900L/Z900)

1) Remove the Coupling Joint from the hose.

2) Remove the back-end Gasket.

3) Pull and remove the water tube, and remove the Non-Retraction Valve.

4) Insert the new Non-Retraction Valve securely and remount the back-end Gasket.
* Refer to Spare Parts List to identify the correct parts.
