8 7. Sterilization Sterilize the Handpiece Attachments, Burs and Motor Only. For the sterilization method, we recommend the autoclave sterilization Tighten method. Note: Attachments, burs and motor Must Be Cleaned and Sterilized Before first use After Each Patient. Sterilizing the Motor 1) Turn off the Power. Autoclave Plug Motor Cap 2) Detach the motor from the Motor Cord. (Refer to 4. (1) Connecting / disconnecting the Motor and the Motor Cord) Fig.10 3) Clean the surface of the motor with a soft brush (do not use a metal brush), then wipe with cotton moistened with isopropyl alcohol. 4) Screw the Motor Cap onto the Motor. Put the Autoclave plug onto the motor insert. (Fig. 10) 5) Autoclavable up to max. 135 C. ex.) Autoclave for 20 min. at 121 C, or 15 min. at 132 C.. Sterilization at 121 C for more than 15 minutes is recommended by EN13060 or EN ISO Sterilizing the Handpiece Attachments and Burs 1. Wear puncture resistant gloves to prepare attachment for sterilization. 2. Confirm that a bur is in the attachment chuck (never operate attachment without a bur in place) 3. After each patient, flush air and water by running attachment for 20 seconds. 4. Remove bur. Disconnect attachment from motor. 5. Disconnect motor from tubing by unscrewing coupler (counter-clockwise) and pulling motor in the axial direction (direction of E connector). 6. Clean all external surfaces of attachment and motor using a small toothbrush and soft cloth with isopropyl alcohol. 7. Dry thoroughly, lubricate attachment 8. Sterilize: Note: To Prevent Damage To the Bur, Use an Autoclavable Bur Block. Attachments and burs should be autoclaved using one of the following two methods: a. Three pre-vacuum cycles for 4 minutes at 134 C ± 1 OR b. Autoclave using the gravitation method for at least 90 minutes at 121 C ± 1 Follow the manufacturer s operating manual. 9. Remove attachments and bur(s) from sterilizer after drying cycle ends and allow to cool in bag. 10. Connect motor to tubing. 11. Connect attachment to motor. Install bur. 12. Run attachment for 20 seconds. Note: An unwrapped attachment, bur and motor need to be used immediately or sterility is not maintained. Do not exceed the sterilizer manufacturer s guidelines for load capacity. Use only paper or paper/plastic bags. Always use complete dry cycle of sterilizer. Always allow product to cool in bag to room temperature prior to using. Contact your sterilizer manufacturer if moisture remains inside bag and on product after drying. : Use steam sterilization exclusively for complete sterility. Never dry heat sterilize, ultrasonically clean, expose to chemical disinfection or cold sterilization by: Immersion techniques Surface wipes, hand soaps or detergents Surface spray Attachment bags that contain disinfectants Do not Autoclave (or any other high temperature Sterilization) Control Box, AC Adapter, Motor Cord. Do not lubricate the motor. Do not wipe or immerse the system in acidic water or acidic solutions. Do not sterilize with dirt on the surface. As this may cause rust. 8

9 8. Maintenance Replace O-Rings if it becomes difficult to connect handpiece attachments or there is an air or water leak. (1) Changing the Oring Remove the O-Ring at the Motor Insert with a pointed tool, and mount the new O-Rings into the groove. There are 4 O-Rings on the Motor. The Blue O-Ring is thinner than other 3 O-Rings. Make sure to install in correct order. O-Ring (Blue) O-Ring (Black) Fig.11 Effects of deteriorated O-Rings: Air/Water leak Air/Water does not turn off Vibration Difficult to connect/disconnect the handpiece (2) Replacing Bulb 1) Turn off the power. 2) Loosen Motor cover and detach it from the motor. Remove the old light bulb using a small screw driver. (Fig.12, 13) 3) Align and insert the connector of the new bulb into the socket hole securely. Screw the Motor cover securely to the Motor. Cover Motor Fig.12 Make sure to turn off the power. Do not touch the glass section of new bulb. Bulb Fig.13 9
