Preparation for Use
CAUTION
• Pay attention to the Scaler Cord not to be twisted when tightening the Tip.
• Be careful of the pointed end of the Tip when replacing a Tip that is longer than the Tip Wrench.
• Do not use a Tip which has a crack, a bend, or rust. The Tip may snap during use.
• If the Tip Wrench is rotated at an angle, the threads may bend or vibration becomes insufficient.
• If installed with the Handpiece or the threads of the Tip having dirt on, abnormal sound or weakening/
stopping of vibration may occur. Remove the dirt from the threads.
• Do not sharpen or change the angle of the Tip. It could cause abnormal sound, Tip breakage, or stopping
of vibration during use.
• Tip is a wear item. When it is worn, abnormal sound, weakening/stopping of vibration or breakage may
occur. When abnormal sound or vibration weakening is detected, replace the Tip with a new one.
• Tighten the Tip with attached Tip Wrench until hearing a clicking sound. If the tightening is not enough, it
may cause abnormal sound or vibration weakening.
• When replacing the Tip, be sure to wear sterilized gloves and use a sterilized Tip, Handpiece, and Tip
Wrench.
• Be sure to use the Tip at or under the maximum power written on the Tip Case or the Tip Power Guide.
If it is used over the maximum power, a noise, breakage of the Tip, or damage to the tooth surface may
occur.
• Other than the prosthesis removing Tip (metal crown and porcelain crown), do not contact anything to the
prosthesis to prevent from coming off or being damaged.
• When connecting/disconnecting the Handpiece, be sure to remove the Tip to prevent injuries.
• If the Tip stops vibrating during use, take out the Handpiece from the patient’s mouth and step on the
foot control again. If the condition does not improve, check the connection of the Tip because there is a
possibility that the Tip has become loose during use.
• If looseness of the Tip, a noise, or vibration weakening does not improve even after tightening the Tip with
the Tip Wrench until hearing a clicking sound, the Tip Wrench might be worn. Replace the Tip Wrench
after about one-year of use because it is a wear item.
• When using a file as a Tip to enlarge the root canal, ensure you understand its characteristics and the
application area.

Preparation for Use
Measure the length of the Tip end by comparing with the corresponding Tip illustration and check the
replacement time. It is recommended to replace the Tip when the length of the Tip becomes “Yellow Line:
1mm worn” for safe and efficient use.
4-4 Using the Tip Card
Green Line : Not worn.
(No replacement is needed.)
Yellow Line : 1mm worn.
(Replacement is recommended.)
• Tip is a wear item, check the abrasion degree with the attached Tip Card and replace the Tip properly.
• Tip is a wear item, the tartar removal
efficiency decreases by 25% when the Tip
end is worn by 1mm, and 50% when the
Tip end is worn by 2mm.
Also, the vibration condition may change
and damage the tooth surface. Check the
abrasion degree with the Tip Card regularly
and replace the Tip with a new one early.
