NSK Varios 170 Bedienungsanleitung Seite 7

WARNING
Do not connect the supplied G16 Tip to a handpiece other
than a Varios2 handpiece (VA2-LUX-HP / VA2-HP). Doing
so may cause fracturing of the Tip or scratches on the
surface of the dentition, prosthesis, etc. due to an increase
in vibration amplitude.
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.
Tip Card
CAUTION
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.
