Please read this Operation Manual carefully before use and file for future reference.
１． CAUTIONS
！
・This handpiece is designed only for dental clinical use.
・Prior to each use, ensure that all instrument and accessories must be in proper conditions before operation as per
instructions enclosed.
・Consideration for the patient's safety must be taken, when using the handpiece.
・Before each use, be sure that burs are properly seated and secured in the handpiece.
・Use burs from reputable manufactures, with ISO standard of shaft diameter of 1.59〜1.60㎜, a max. total length of
26㎜(1.02")(Standard or Torque heads) and a max. head diameter of the 2㎜ ( .0787"). Burs which does not agree
from the stated measurements should not be used.
・After extended use the handpiece may become noisy, replace the cartridge with a new one manufactured by NSK.
Failure to replace the cartridge may cause accidents or impair operator , s hearing.
・Depressing the push-button while handpiece bur is in rotation 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 injury to the patient may occur.
・NSK turbines should not be rebuilt or recycle by un-qualified NSK technican. Replacing or mishandling the bearings
only may result in unexpected failure causing patient injury due to different in wear factors of new vs. old
components, or mishandling.
・Burs must be inserted all the way into chuck for proper bur retention.
Extending the bur, in-stablelaty could result in bent burs, indequate cooling and improper grip of the bur resulting in
personal injuries.
２．Features
The Ti-Max handpiece outer casing is manufactured with advance technology and metallagy: TITANIUM
・Titanium is used for its stablity, hardness and light weight as compared to other material.
・Titanium is also non-allergic to aloy sensitive patient.
・The CLEAN-HEAD (PAT.) system, incorporated in the handpiece, prevent suction of oral fluids and debris in a patient's mouth
into the turbine exhaust line of the handpiece and tubings of the dental unit and environment.
・The NON-RETRACTION VALVE incorporated in the coupling joint end, a quick connect coupling for Ti-Max series
handpiece, effectively prevent back blow of oral fluids from the patient , s mouth through the water spray outlet of the handpiece
head.
・Water spray system is made as an integral part of the cartridge. Clogging of the water line and the spray outlet is thus
minimized. The spray system is renewed at each cartridge replacement.
・Provision of the spray outlet in the cartridge brings the spray outlet much closer to the bur.
The visibility angle is greatly improved even with three jet spraying (PAT.).
・Ti-Max handpieces are autoclavable up to 135℃.
・Improved Glass Rod Optics located at the head greatly illuminates the working area, improved visibility for diagnosis and
treatment,
causing less eye strain to the operator. (A500L, A600L, A700L)
・Push button type chucking system ULTRA PUSH cartridge.
・Twist free, 360゜ rotation minimizes hose drag.

４．Connect the Coupling Joint
a Coupling Joint to handpiece hose
Align the tubes at the back end of the coupling with the corresponding holes
in the hose connector. Insert the coupling into the hose connector and tighten
the hose nut by turning it clockwise.
s Connecting Coupling Joint to the handpiece
Insert the handpiece into the coupling until a click is heard as shown in Fig.1.
d Disconnecting handpiece from coupling joint
When the handpiece is to be disconnected from the coupling for autoclaving
or changing the handpiece, slide back the cennector ring as shown in Fig.２,
and the handpiece pops out.
CAUTION
！
DO NOT slide back the connector ring while the handpiece is under air
pressure. The handpiece may be ejected from the coupling as a result
of the pressurization.
５．Drive Air Pressure
Using the NSK pressure gauge, calibrate the drive air pressure to 0.2−0.25MPa (2.0-2.5kgf/F) at the arrow point.
If a pressure gauge is not available, the pressure can be set between 0.22-0.27MPa (2.2−2.7kgf/F) at the chair side pressure
gauge.（Fig.３）
CAUTION
！
DO NOT exceed the recommended air pressure
to prevent premature ball bearing failure.
６． Cautions on Burs
！
・DO NOT use non-standard burs. The ISO standard shank diameter is φ1.59−1.60㎜.
・DO NOT use bent, worn, or damaged burs.
・Always use clean burs. Uncleaned burs may cause unwanted amount of pressure on the chuck.
・Insert a bur all the way into the chuck until it stops.
・DO NOT use short shank burs in STANDARD or TORQUE handpiece.
・Use short shank burs in Mini head handpiece（A500, A500L） .
７．Changing Burs
a Removing Burs
Push the push button in the head cap with thumb to click, and remove the bur.（Fig.４）
＊Note：Push button spring is of a double action. Push until the button is in flush with the head cap.（Fig.５）
s Mounting Burs
Insert the bur into the head until it stops（４-５a deep). Push the push button and further insert the bur all the way into the
head until it stops.
After the bur is held in place in the chuck, push the bur further into the chuck
before use, so that the chuck grip power will increase.（Fig.６）
CAUTION
！
In case a cutting is performed under heavy vibrations such as in crown removal, there may be a case where the bur
gets stuck in the head.
Pull it out with pliers with the push button kept pushed hard.
This case may be prevented if you often change the position of the bur in the chuck.
８．Lubrication
Supply PANA SPRAY or/and Care3 Plus after each use and/or before autoclaving.
■ (Fig. 6)
PANA SPRAY
① Attach the PHATELUS nozzle into the spray outlet of PANA-SPRAY.
② Insert the PHATELUS nozzle into the handpiece back end.
③ Spray for １−２ seconds. Hold the spray can upright.
（Fig.７）
■Care3 Plus
NSK Care3 Plus automatic handpiece cleaning and lubrication system
After connecting the handpiece to the correct adaptor, activate the Care3 system per
the Care3 System instructions.
