DANGER • Use the specified batteries for this product. Never use any other batteries than those that NSK specifies. • Do not disassemble or alter the device.

WARNING • This product is not built as waterproof. Do not spill water or a chemical solution onto or into the motor handpiece or battery charger. Failure to do so may result in fire or electric shock due to a short-circuit or rusting. • If you should notice battery fluid leak within the motor handpiece, deformation of the motor handpiece casing or partial discoloring, immediately stop use and contact your dealer. • Should the leaking battery fluid get into your eyes, immediately wash eyes thoroughly with clean water and see your doctor. Failure to do so may result in loss of sight. • Should the battery fluid leak and adhere to skin or clothing, immediately wash the exposed skin thoroughly with clean water and completely wash away the fluid. Failure to do so may result in skin complications. • If you will not use the product for a long period of time, remove the batteries from the handpiece to avoid fluid leak. • The system may present a possibility of malfunction when used in the presence of electromagnetic interference wave. Do not install the system in the vicinity of the device which emits magnetic waves.

CAUTION • Exercise sufficient care in using the product by giving patient safety first priority. • The product is to be used only for dental treatment by qualified personnel. • Use our recommended batteries only. • Use the NSK AC adapter for this product. Never use any other AC adapters.

• Do not use a bent, damaged, deformed or non-ISO-conforming file. Using such a file may result in personal injury due to its unexpected breaking or flying off during rotation. • Do not use or leave the product in a high-temperature environment such as under strong direct sunlight, in a car under a blazing sun, by a fire, or near a stove. • Check the product before use by rotating it, paying attention to looseness, vibration, noise and temperature (heat generation). If any abnormal condition is found even slightly at that time, immediately stop use and contact your dealer. • Do not allow any impact on the shank. Do not drop the handpiece. • Always clean the shank of the file to be installed. Allowing dirt to enter the chuck could cause loss of concentricity and deterioration of chucking force. • Before changing the head or bur, turn off the power of the motor handpiece. Changing with the power kept on may cause unintended rotation by accidental touch of the ON/OFF button. • Pay attention to the direction of batteries when setting. Forcible setting in the wrong direction may cause damage and fluid leakage due to a short circuit. • Do not allow conductive materials such as wires, safety pins, etc., to enter into the battery case. • If chemical, solvent or antiseptic solution is deposited on this product, immediately wipe it away. Discoloration or deformation may occur if left as it is. • The system functions normally in the environment where the temperature is at 1040˚C (50-104˚F), humidity at 10-85% RH, atmospheric pressure at 500-1060hPa, and no moisture condensation in the Control Unit. Use at outside of these limits may cause malfunction.

NOTICE • During vibration, the motor handpiece and the motor handpiece cord may affect computer and LAN cable. Noise could be heard during operation near a radio receiver. • The motor handpiece consumes electricity very slightly even when the power supply is off. In addition, fully-charged rechargeable batteries, in general, discharge gradually over time even though it is not used. It is recommended to recharge the batteries just before use. • When the motor handpiece stops automatically by detecting a low battery voltage, turning on the power again after a while may not detect the low voltage immediately. This is not a failure, but due to battery characteristics. Since the voltage drop does not coincide with the remaining battery capacity, consider it only as a yardstick. • Recharge rechargeable batteries after they deplete as much as possible. Repeating short-time use and subsequent recharging may shorten their operating time due to the “memory effect.” Batteries may recover after repeating complete discharge and full charge for a few times. (This product is equipped with a “Refresh Mode” for this purpose.) • The used nickel metal hydride batteries are recyclable, but their disposal may sometimes not be permitted by the country. Return them to your dealer. • When disposing of the control unit and foot control (Optional), follow the instructions of your local government for disposal, as they contain materials which may become industrial waste. • When discarding the contra angle head and motor handpiece, dispose of them as medical waste. • Users are responsible for operational control, maintenance and inspection. • Store the system in the place where the temperature is at –10-60˚C (14-140˚F), humidity at 10-85% RH, atmospheric pressure at 500-1060 hPa, and the system is not subject to air with dust, sulfur, or salinity. • When trouble is found, send to dealer.

• Connect to AC120V or AC230V power supply only. Otherwise, it may cause a malfunction. • Since the AC IN lamp lights to indicate that the supply power is on, it does not go out even after a charge is completed. See the CHARGE lamp to check the charging conditions. • The standard charging time is about 5 hours, but it varies depending on use conditions of batteries, temperature and whether the batteries are new or old. Especially, old batteries may remarkably shorten both the charging and operating time. • When charging a battery, the temperature of the battery is measured. Therefore, if this product is placed in an environment where the temperature changes rapidly (for example, near a window exposed to sunlight, near the outlet of a air conditioner, or heater.), the battery cannot be properly charged. Put this product in a place where the temperature varies little. • In the following cases, it may not start charging: ™The temperature of a battery is too low or too high. (less than 0˚C (32˚F) or more than 40˚C (104˚F). ) ™The voltage of a battery is sufficient. (This does not necessarily mean fully charged.) ™A battery is not connected. ™The voltage of a battery is abnormal. (See P.20 10. “ERROR CODE”) • Batteries are automatically charged depending on conditions, even when the power is on. But when the motor handpiece is used, charging is suspended to protect the battery.

NOTICE Fig. 11

AUTO REVERSE OFF The motor handpiece stops without reverse rotation. In this instance, the LCD panel shows “ ” and the rotation speed alternately.

NOTICE • When the reverse rotation (R) is set, this auto reverse function is not activated. • When the batteries go down (when the mark of the remaining amount of the batteries indicates “ , ”), the actual load may not reach the preset torque limit value. In this case (in the case of operation by batteries), this auto reverse function will not be activated. When high torque is required, use the AC adapter or use this product in a condition where the batteries are not significantly consumed (when the mark of the remaining amount of the batteries indicates “ , ”). • If a load is continuously applied to the motor handpiece, it may automatically stop to prevent overheating. (The torque limit value indicates “ ” on the LCD panel). In this case, leave the motor handpiece for a while until it cools down. When the display returns to normal, the motor handpiece can be used.

(6) Completion of Medical Treatment When the treatment is completed, return the motor handpiece to the handpiece stand and hold down the POWER key for more than one second to turn off the power.

NOTICE

• The program cannot be memorized while the motor handpiece is in motion. • The rotational direction is not memorized in the program. The program cannot be memorized if the rotational direction is set to the reverse rotation (R). • If the PROGRAM key is kept pressed, it is fast-forwarded. • The program is not memorized unless the MEMORIZE key is held down for more than one second. If the program number is changed by the PROGRAM key without pressing the MEMORIZE key, the initially memorized preset values remain. (Cancel function)

(2) Initialization of Program (Factory-set configuration) The program can be returned to the original state configured at the time of factory shipment, if setup becomes confusing. qTurn off the power, when the power is on. wConnect the AC adapter and confirm that the AC IN lamp lights up. eHold down the POWER key for more than one second, while pressing the AUTO REVERSE key and MEMORIZE key at the same time. rRelease the keys when the LCD panel indicates “ ”, and re-press the MEMORIZE key while this is displayed. tInitialization is completed, when “ ”is displayed.

(3) Battery Refresh

(4) Calibration

Nickel-metal-hydrate batteries may result in a decrease in charging capacity, if additional charging (repeating a cycle of short-time use and recharging) is made. (Generally, this phenomenon is called a “memory effect.”) This Battery Refresh function is to resolve this phenomenon. qTurn off the power if the power is on. wConnect the AC adapter and confirm that the AC IN lamp lights. eHold down the POWER key for more than one second, while pressing the REVERSE key. rThe alarm sounds for a length of time, and the refresh mode is activated. At this time, the mark of the remaining amount of the batteries on the LCD panel is animated in the direction opposite to display at the time of charging. At the same time, the CHARGE lamp flashes slowly. tLeave it as it is. The batteries are discharged and recharged automatically. yHold down the POWER key for a while, when you want to stop this process. (At this time, the power does not turn on.)

This function is to decrease fluctuation in the rotation speed of the motor handpiece and the difference in torque by the contra angle head. qLubricate the contra angle head with the PANA SPRAY (option). (Refer to the “P17 7. (1) Lubricating Contra Angle Head.”) wTurn off the power if the power is on. eConnect the AC adapter and confirm that the AC IN lamp lights. rTurn on the power. tHold down both buttons of the SPEED key simultaneously for more than one second. yThe LCD panel displays “ ” with the alarm sound. uAttach the contra angle head to the motor handpiece and press the MEMORIZE key. iIf the motor handpiece begins to rotate, leave it as it is until it stops. oThis process ends, if the rotation stops and the LCD panel display returns to its original state. !0If you want to stop this process, turn off the power.

NOTICE NOTICE • This function is not activated, if not driven by the AC adapter. • It takes about maximum of 5 hours to discharge batteries. • It takes 5 hours to discharge and 5 hours to recharge. Therefore, total of about 10 hours are required. For example, if dental treatment is finished at 7 p.m. and the refresh mode is set, the batteries will be fully charged by 5 a.m. the next morning at the longest. • This function is not required for each charging. Try this function, if the operating time is shortened even if the batteries are relatively new. • Do not repeat activation and deactivation of the refresh mode in a short time. It may result in enhancement of the memory effect. • This function is fully effective for solution of a “memory effect.” However, it cannot be solved completely at one time due to characteristics of batteries. We recommend you repeat this process a few times according to need.

• Lubricate the contra angle head before Calibration. • This function does not operate if AC adapter is not used. • Do not touch or apply a load to the rotating shaft of the contra angle head. It obstructs accurate measurement. • This function cannot completely absorb the individual difference of the actual motor handpiece and contra angle head.

(5) Alarm Sound Volume Control The alarm sound volume can be controlled at the three steps of “BIG VOLUME, SMALL VOLUME and LIMITED OFF. ” qKeep holding down both buttons of the PROGRAM key simultaneously. wThe alarm mark on the LCD panel changes, and the sound volume changes. eRelease the PROGRAM key when the sound volume reaches your required level and the required sound level is set up.

NOTICE • The sound level is retained, even if the power is turned off. • If P.14 6. (2) “Initialization of Program (Factory-set configuration)” is executed, the sound is set to “BIG VOLUME.”

ex.) Autoclave for 20 min. at 121˚C, or 15 min. at 132˚C.

CAUTION

(2) Cleaning Motor Handpiece When the motor handpiece becomes dirty, wipe it off with a cotton cloth moistened with rubbing alcohol.

CAUTION • Do not lubricate the motor section of the motor handpiece. • To clean the motor handpiece, do not use any solvent such as benzine and, thinner. • Before mounting the lubricated contra angle head to the motor handpiece, wipe off extra oil. Stand on its end or lean it in the proper position for gravity draining. Mount it after excess oil has been drained. • Hold the contra angle head securely to prevent it from flying off by the pressure of the spray. • Supply lubricant until it comes out of the handpiece head (for approx. 2 seconds). • Do not use a spray can upside down. In such a case, only spray gas comes out and oil is not sprayed.

• Do not apply high-temperature sterilization methods such as autoclave sterilization to any part other than the contra angle head. • Skip dry cycle if the temperature could exceed 135˚C (275˚F). • Since the bottom tray inside the chamber of the autoclave is close to a heater and the temperature in that place may locally exceed 135˚C (275˚F), place the head on the central or upper tray.

9. CHANGING BATTERIES The motor handpiece uses rechargeable batteries. They can be recharged 300-500 times, depending on the use conditions of the motor handpiece. If the operating time or recharging time becomes shorter or the rotation power becomes weaker, although the “memory effect” described in “ NOTICE” is not applicable, the life of the batteries is suspected. In such a case, ask your dealer to replace the batteries or replace them with new ones by yourself. (Refer to the “ Changing Batteries.”) When replacing them by yourself, be sure to observe the following “ CAUTIONS ON CHANGING BATTERIES.” Note that NSK shall not be held liable for any malfunction or failure resulting from your not following the “ CAUTIONS ON CHANGING BATTERIES.”

CAUTIONS ON CHANGING BATTERIES • Do not open any part other than the battery cover. • Be sure to purchase and use only the recommended batteries. Otherwise, batteries may cause damage, fluid leakage or explode. • Do not work with wet hands. This may cause trouble due to short-circuiting of batteries and moisture infiltrating this product.
