9. Motor Cap
When the contra angle head is removed from the motor
handpiece for battery charging, lubrication, or steriliza-
tion, mount the motor cap onto the motor handpiece
to prevent debris from entering.
10. Safety System
The motor handpiece monitors temperature of the batteries. If the batteries can potentially become abnor-
mally hot, this system functions and the motor handpiece automatically stops. In such a case, wait until the
motor handpiece cools down sufficiently. If this safety system functions repeatedly, either the batteries or
motor handpiece is not in the normal operating condition and you should contact your dealer.
11. Changing Batteries
The motor handpiece uses rechargeable batteries. They can be recharged 300-500 times, depending on
the use conditions of the motor handpiece. If the operating time becomes shorter or the rotation speed
becomes slower, although the "MEMORY EFFECT" described in "
may be at the end of their life expectancy. In such a case, ask your dealer to replace the batteries or replace
them with new ones yourself. (Refer to the " Changing Batteries. " ) When replacing them by yourself, be sure
to observe the following "
shall not be liable for any malfunction or failure resulting from you changing the batteries yourself and not
following the "
CAUTIONS ON CHANGING BATTERIES. "
CAUTIONS ON CHANGING BATTERIES
- Do not open any part other than the battery cover.
- Use only batteries as specified by Coltène/Whaledent.
- Designated Batteries : AAA (marking may be different) nickel metal hydride batteries, nominal 1.2 V
- Do not use non-charging type batteries such as alkaline batteries and manganese batteries. Charging
with these batteries may cause fluid leaks, explosion or chlorine gas generation.
- Should the battery fluid leak and get into your eyes, immediately wash thoroughly with clean water and
seek medical attention.
- Should the battery fluid leak and adhere to skin or clothing, immediately wash the exposed skin thor-
oughly with clean water and completely wash away the fluid. Failure to do so may result in a skin irrita-
tion.
- Always replace two batteries of the same type by the same manufacturer at the same time. Using batter-
ies of different-types, an exhausted battery with a fully charged one, or a new battery with an old one
may cause a fluid leak or explosion.
- Do not work with wet hands. Failure to do so may result in rust formation on battery terminals or mois-
ture intrusion inside, and could cause failure of the product.
- Do not reverse positive (+) and negative (-) when fitting the batteries.
