• When attaching or removing a Tip, which is longer than the Tip Wrench, be careful that the protruding Tip CAUTION does not cause an injury. • Do not use a Tip which has been damaged, bent or corroded as it will be weakened and may break while in use. • To avoid bending of the Tip thread or disengaging of the Tip, always make certain that the Tip is inserted at the correct angle and firmly tightened. • If debris is found on the Tip thread clean the Tip immediately so as to avoid possible weak vibration • Do not attempt to sharpen or bend the Tip as this may cause the Tip to break during operation, or the vibration may be weakened. • When Tip become worn vibration may weaken or the Tip may suddenly break. If a weak Tip is detected replace with a new one. • Tips need to correctly inserted and tightened using the Tip Wrench. If the Tip is not tightened sufficiently vibration may be weak. • When inserting a Tip always wear surgical gloves and ensure the Tip, Handpiece and Tip Wrench are in an hygienic condition. • Before connecting or disconnecting the Handpiece Cord or Irrigation Tube make sure to remove the Tip first to avoid injury by the Tip. • Tip Wrench will wear with frequent use time and may need annual replacement. • Use only genuine NSK Tips. Other brand Tips may cause malfunction, damage or injury: - Poor vibration when an incompatible thread has been forcibly fitted. - The patient may swallow pieces of broken non genuine Tips. - Damage or premature wear of the Handpiece thread.

• Make sure that the Tip does not rest on the Handpiece Stand. CAUTION • Make sure that the Handpiece rests horizontally on the Handpiece stand, and not at an angle. • To maintain an hygienic condition, the Handpiece Stand should frequently be cleaned with alcohol. Not horizontal

No Tip contact Fig. 19

6 Check before treatment Before use, operate the product without patient contact and check the following points. If any abnormality, such as low vibration, noise, heat, is detected at anytime disconnect the product and contact your Authorized NSK Dealer. -Is irrigation solution flowing correctly at the Tip? -Is the Tip vibrating correctly? -Are there any abnormalities at the Tip, Eg. vibration, noise and heat? -Is the Handpiece illumination operating correctly?

7 Operating method 7-1 Check Irrigation

1) Confirm that the Irrigation Tube correctly connected to the Coolant Solution Pack, the Irrigation Pump and the Handpiece. 2) Turn ON (-side) the Power Switch. 3) Open the Tube Clamp which is placed between the Irrigation Needle and the Irrigation Pump. Then, depress the Ultrasonic ON/OFF Button on the Foot Control and confirm that the irrigation solution correctly flows from the Tip. When a new Irrigation Tube is used, it may take several seconds before irrigation solution flow commences.

7-2 Set the Power Level

1) Change the Mode – Use MODE key. 2) Select the Program No. – Use PROGRAM key. 3) Adjust the Power Level – Use POWER key. 4) Adjust the Coolant Flow Level – Use COOLANT key. 5) Adjust the Handpiece illumination intensity – Use LIGHT key. SURG 6) Select the Burst Output Level – Use BURST key. (In SURG Mode only).

• Use the tip ONLY in the correct mode and never exceed the maximum power defined for the tip by the tip CAUTION power guide. If used outside the prescribed power range the Tip may break, and the tooth surface or soft tissue may be damaged. • ONLY tips specified for maintaining prostheses can be applied to prostheses. Contact of other types of tips with prostheses may cause Tip breakage.

7-3 Activation

The Tip will commence vibrating when the ON-OFF Foot Control button is depressed.

• Start with a low power setting within the power range, observing the patient’s reaction and according to CAUTION the treatment plan. • Always use the irrigation. If the irrigation is not sufficient, the Handpiece may excessively heat, or oral injury may occur. • Do not apply excessive pressure to the Tip. • Do not place the active Tip anywhere other than the specific treatment area, as the ultrasonic vibration may cause oral injury. • Even if the power level is correctly set for the Tip in use application of excessive pressure to the Tip may cause Tip damage. Should Tip breakage occur, immediately evacuate the oral cavity of any Tip pieces using strong suction. • If Tip vibration reduces during operation, release the Foot Control activation button, and then again depress the Foot Control activation button. If the vibration level still does not return to normal check that the Tip is correctly and firmly positioned. Incorrectly inserted Tips may loosen during operation and power loss may be experienced. • Do not connect or disconnect the AC power or the Handpiece Cord while Foot Control is depressed.

8 Various functions 8-1 Memory function
