The motor handpiece uses rechargeable batteries. They can be recharged approximately
300-500 times, depending on the use conditions of the motor handpiece. If the operating time
becomes shorter or the rotation speed becomes slower, the "memory effect" described in "
NOTICE" may be applicable, or the life of the batteries could be exhausted. In such a case, ask
Brasseler USA to replace the batteries or replace them with new ones by yourself. (Refer to the
"S Changing Batteries.") When replacing them by yourself, be sure to observe the following "
CAUTIONS ON CHANGING BATTERIES." Please note that BRASSELER USA shall not be
liable for any malfunction or failure resulting from your not following the " CAUTIONS ON
CHANGING BATTERIES."
Cautions on Changing Batteries
9. Changing Batteries
• Do not open any part other than the battery cover.
• Use batteries designated for this motor handpiece.
• Designated Batteries : AAA (marking may be different)
nickel metal hydride batteries, 600-700 mAh, nominal 1.2V
(Or Ni-Cad batteries, 200-300 mAh, nominal 1.2V. However, please
take note that the operating time shortens because of their capacity.)
• 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 in
clean water and see your doctor.
• Should the battery fluid leak and adhere to skin or clothing, immediately wash the
exposed skin thoroughly with clean water and completely wash away the fluid. Failure to
do so may result in a skin disorder.
• Always replace two batteries of the same type by the same manufacturer at the same
time. Using batteries 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. To do so may result in rust formation on battery terminals
or moisture intrusion inside, and could cause failure of the product.
