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
* The Tip Card can be used to check the following
tips : G1, G4, G6, G8, G9, P1/P1D, P10, and P20
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.
