Using the Tip Card
• Tips are wear items. Use the supplied Tip Card to check the Tip condition and replace the Tip if necessary.
CAUTION
Place the neck of the Tip in the cut out of the Tip Card. Measure the length of the Tip and check the replacement timing (Fig. 18). To
guarantee safe and effective use, it is recommended that Tips be replaced with the Tip meets the yellow line (1mm of wear).
Tip Card
• Tips are consumables. The efficiency of dental scaling decreases
approximately 25% when the top of the Tip wears 1mm and
CAUTION
approximately 50% when it wears 2mm. In addition, the vibration
condition changes owing to the wear, which may damage a patient's
tooth surface. Periodically check the Tip wear condition using the Tip
Card, and replace the Tip with a new one in good time.
Green: No wear - Tip is OK
Tip replacement is not necessary.
Yellow: Wear of 1mm - Tip is showing some wear
Tip replacement is recommended.
Red: Wear of 2mm - Tip is badly worn
