・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.

Clogging of the water line and the spray port is thus minimized. The spray port is renewed at each cartridge replacement. ・Provision of the spray port in the cartridge brings the spray port much closer to the bur. The visibility angle is greatly improved even with three-port spraying.(PAT.) ・PHATELUS MACH-LITE XT handpiece and PHATELUS Coupling are autoclavable.(up to 135℃) ・Push button type chucking system ULTRA PUSH cartridge. ・Twist free, 360゜ rotation to minimize hose drag. ３．Specifications Model MLXT-MU MLXT-SU MLXT-TU Head Type Mini Standard Torque -1 -1 -1 Speed 380,000-450,000min (rpm) 380,000-450,000min (rpm) 300,000-380,000min (rpm) Drive Air Pressure 0.2-0.25MPa(2-2.5kgf/F) 0.2-0.25MPa(2-2.5kgf/F) 0.2-0.25MPa(2-2.5kgf/F) Spray Type Triple Water Spray Triple Water Spray Triple Water Spray Chuck Ultra Push(Push button chuck) Ultra Push(Push button chuck) Ultra Push(Push button chuck) φ1.59-φ1.60 φ1.59-φ1.60 φ1.59-φ1.60 Bur Size Short Shank Bur Standard Bur Standard Bur Light Glass Rod Optic Glass Rod Optic Glass Rod Optic Head Diameter φ11.2㎜ φ11.2㎜ φ13.2㎜ Head Height 12.5㎜ 14.6㎜ 14.6㎜ Weight (Head) 43ｇ 43ｇ 54ｇ ＊

s
Connecting coupling to the handpiece Insert the handpiece into the coupling until a click is heard as shown in Fig.２．
d
Disconnecting handpiece from coupling When the handpiece is to be disconnected from the coupling for autoclaving or changing the handpiece, slide back the connector ring as shown in Fig.３， and the handpiece pops out.

５．Drive Air Pressure
Using the NSK pressure gauge, calibrate the drive air pressure to 0.2-0.25MPa (2-2.5kgf/F) at the arrow point. If a pressure gauge is not available, the pressure can be set between 0.22-0.26MPa (2.2-2.7kgf/F) at the chair side pressure gauge.（Fig.４） ！ CAUTION

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 MLXT-SU or MLXT-TU handpiece. ・Use short shank burs in Mini head handpiece（MLXT-MU）. ７．Changing Burs
a
Removing Burs Push the push button in the head cap with thumb to click, and remove the bur.（Fig.５） ＊Note：Push button spring is of a double action. Push until the button is in flush with the head cap.（Fig.６）
s
！
Mounting Burs Fig.６ Fig.５ 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.７）

８．Lubrication
Supply PANA SPRAY or/and Care3 Plus after each use and/or before autoclaving. Remove the handpiece from the coupling and lubricate as follows：
PHATELUS Nozzle (P183-090)
■PANA SPRAY (Fig. 8) ①Attach the PHATELUS nozzle into the spray outlet of PANA SPRAY. ②Insert the PHATELUS nozzle into the handpiece back end. ③Spray for 1 - 2 seconds. Hold the spray can upright. (Fig.8) ■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.
PANA-SPRAY Fig.８
９．Sterilization Sterilization by autoclave is recommended. Sterilization required after each patient as noted below. AUTOCLAVING： ① Brush off excess dirt and wipe clean with alcohol-soaked cloth. ② Remove the handpiece from the coupling and lubricate with PANA-SPRAY as described in the Lubrication section. ③ Insert the handpiece in a sterilization pouch and seal it. ④ Autoclavable up to a max. 135℃. Ex.) Autoclave for 20 min. at 121℃, or 15 min. at 132℃. ⑤ Keep the handpiece in the autoclave pouch to keep it clean until you use it.
！ CAUTIONS ・Skip dry cycle. ・Heating element may be located the bottom of the chamber, and the temperature there locally may exceed the
set value. Place the handpiese on the central or upper tray.
・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.
＊Sterilization at 121℃ for more than 15 minutes is recommended by EN13060 or EN554. ＊Performing sterilization according to our instruction has minimal effect on the instruments. Life span is generally determined by wear and damage due to use. 10．Clean slit after each patient It is important to clean the slit in the head as follows after each patient and before autoclaving to appreciate lasting CLEAN-HEAD performance. (Fig.９) ① Brush off the debris at the slits as shown in fig.10 ． ② Run the handpiece at the rated pressure. ③ Immerse half of the head in clean water while the handpiece is running. ④ Run the handpiece in the water 4-5 seconds. (Fig.11) ⑤ Remove the handpiece, while running, from the water. Stop and wipe dry the handpiece. ⑥ Lubricate before autoclaving. ＊Note：Change water each time.

a Removing the cartridge ① Mount a dummy bur in the chuck. ② Set the wrench on the head cap, turn the wrench counter-clockwise and remove the cap. (Fig.12) ③ Push up the dummy bur, and the cartridge is easily removed from the head. ④ Clean the head interior, when dirty, with PANA-SPRAY. s
Inserting the new cartridge Insert the new cartridge, with its pin aligned in the slot of the handpiece head, straight into the handpiece. ② Hand tighten the cap until finger tight and secure with wrench until the cap sets in place. (Fig.13) ※Optional Cartridge : NMC-MU03 (Cartridge for Miniature head) Order No.P047 NMC-SU03 (Cartridge for Standard head) Order No.P045 NMC-TU03 (Cartridge for Torque head) Order No.P046 ①

・The head cap screw thread is very fine. To prevent it from breaking, use of the wrench from the first thread is not
recommended.
・Before inserting a new cartridge, clean the head interior. ・Make sure that three O-rings（Fig.14）are in place on the cartridge. They are for the cooling water and chip air. Mini

14．Cleaning of the Glass Rod Optic end In case the light has become dim, clean the Glass Rod Optic end with an alcohol-soaked cotton swab. (Fig.21) Do not use a pointed tool or sharp edges to clean the Glass Rod Optic end. They may damage the mirror finish and reduce the light transmission efficiency. If the Glass Rod Optic end has become damaged, send the handpiece to your local distributor for repair.

15．Cleaning of Spray Ports When spray nozzle are clogged, or spray does not exit evenly from three ports, clean the ports as follows： ① Remove the bur or bur blank from the chuck. Remove the head cap, and the cartridge from the head. As disc ribed in the Replacing Cartridge. ② Take out the cleaning wire from the back end of the brush holder. Insert the wire straight into the spray nozzle 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 O-Ring Fig.22 cooling efficiency deteriorates. See Fig.22. ③ Make sure that cleaning wire reaches the deepest groove,the chip air groove, (Fig.23). Brush off the debris. ④ After use, clean the cleaning wire. Push into the brush holder with Chip Air Groove the pointed end of the wire inward. Water Groove Spray Port

16．Non-Retraction Valve A Non-Retraction Valve is equipped in the PHATELUS Coupling Joint, which shuts off the water retraction right at the handpiece head, to prevent oral fluids sucked into the water line. Once in a while, use a syringe to check its effectiveness and inject air to clean the valve seat. (Fig.24) Pull When the valve does not seem functioning, use the syringe and inject air into the water tube of the back-end. Most dirt may be blown out Note：Syringe is not supplied with the handpiece. Fig.24 of the seat. To replace the valve, remove the back-end gasket. Pull and remove the water tube, and replace the Non-Retraction Valve. (Fig.25) Water Tube
