CAUTION
NOTICE
ŘAlways insert the bur all the way into the chuck.
ŘRemove the bur only after the handpiece has completely stopped rotating.
ŘAlways keep the bur shank clean.
ŘEntry 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.
ŘDo not exceed the bur speed recommended by the bur manufacturer.
ŘDo not exceed maximum bur length recommended by the handpiece manufacturer.
ŘDo not apply excess pressure to the bur as it may break or bend or become difficult to remove.
ŘDO 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.
ŘGrip the handpiece while placing your thumb tip on the Push button which makes it easier to depress the button.

CAUTION
ŘAfter 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.
ŘTo clean the product never use any solvent such as benzine or thinner.
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.

8-4 Cleaning (Spray Port)
When spray ports are clogged, or spray does not exit evenly from the ports, clean the ports (Fig. 8).
8-3 Cleaning (Optic)
Wipe clean the Glass Rod tip with an alcohol-immersed cotton swab. Remove all debris and oil (Fig. 7).
CAUTION
ŘDo NOT use a sharp tool to clean the Glass Rod. It could damage the glass and reduce the light
transmission.
CAUTION
ŘDo 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.
ŘDo 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.
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.

16
CAUTION
NOTICE
ŘAutoclave sterilization is recommended for the product. The validity of other sterilization methods is not confirmed.
ŘDo not touch the product immediately after autoclaving as it will be very hot and must remain in a sterile condition.

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 ring.
* Refer to Spare Parts List to identify the correct parts.
CAUTION
ŘDo not force the new replacement O-ring with excessive pressure.

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.
