6-2 Changing O-Ring
An O-Ring is located in the Handpiece Cord Connector. Use a pointed tool to remove,
and mount new O-Ring into the groove. (Fig. 10)
* Optional O-Ring: Order No. 0310020080
6-1 Cleaning of Optic Fiber (Varios 170 LUX)
Wipe the debris off the end of the Optic Fibers at the
handpiece with alcohol soaked cotton swab. (Fig. 9)
Do not use any sharp pointed tools to clean the
Optic Fiber End Face. In case the light degradation,
contact your dealer.
How to use the Tip Card
1) Place the neck of the Tip in the cut out.
2) Check wear of the Tip.
3) See the green, yellow and red line to check wear of the Tip. *See below what each color means. At NSK we recommend
to replace a Tip when the Tip meets the yellow line (wear of 1mm) to guarantee safe and effective use.
Green: No wear - Tip is OK
Tip replacement is not necessary.
Red: Wear of 2mm - Tip is badly worn
Tip replacement is necessary.
Yellow: Wear of 1mm - Tip is showing some wear
Tip replacement is recommended.
Tips are consumables. The efficiency of dental scaling
decreases approximately 25% when the top of the Tip
wears 1 mm and approximately 50% when it wears 2 mm.
In addition, the vibration condition changes owing to the
wear, which may damage a patient’s tooth surface. Check
the Tip wear condition with the Tip Card periodically, and
replace the Tip with a new one in good time.
