or explosion.
DANGER

WARNING
• Do not handle the power cord with a wet hand. Doing so may result in an electric shock.
• Do not spill water or a chemical solution onto or into the motor handpiece or battery
charger. Doing so may result in fire or electric shock due to a short-circuit or breakage
due to rust formation.
• Do not disassemble or alter the motor handpiece.
• Do not drop the motor handpiece or battery charger. Place the battery charger on a flat and
stable place.
• Should the battery fluid leak and get into your eyes, immediately wash eyes thoroughly with
clean water and see your doctor. Failure to do so may result in loss of sight.
• 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 skin trouble.
• If you should notice a battery fluid leak within the motor handpiece, deformation of the
motor-handpiece casing or partial discoloring, immediately stop use and contact Brasseler USA.
• If the product will not be used for a long period of time, remove the batteries to avoid fluid leak.
• Exercise sufficient care in using the product by giving patient safety first priority
• The product is to be used for only dental treatment by qualified personnel.
• Use commercially available batteries recommended by Brasseler USA.
Read carefully the instruction manual by the battery manufacturer before use.
• Do not use a bent, damaged, deformed or non-ISO-conforming bur, as this may result in personal
injury due to its sudden breaking or flying off during rotation.
• Do not use or leave the product in a high-temperature environment such as under strong direct
sunlight, in a car under a blazing sun, by a fire, or near a stove.
• Check the product before use by rotating it, paying attention to looseness, vibration, noise and
temperature (heat generation). If any abnormal condition is found even slightly at that time,
immediately stop use and contact Brasseler USA.
• Always clean the shank of the bur before installing. Allowing dirt to enter the chuck could cause
loss of concentricity and deterioration of chucking force.
• Before changing the head or bur, turn off the power of the motor handpiece.
Changing with the power on may cause unintended rotation by accidental touching of the
ON/OFF switch.
• When inserting the motor handpiece into the battery charger, position the handpiece correctly.
Pushing it into the charger forcibly in the incorrect position may cause damage.
• Be careful not to drop conductive parts such as wires and safety pins into the charging terminal
area of the battery charger.
• Before inserting the motor handpiece into the battery charger, wipe it clean. If the charging
terminal area becomes dirty, rust formation may prevent charging, or result in short-circuit.
• Do not lubricate the motor handpiece.
• Do not heat sterilize the motor handpiece. Do not autoclave.
CAUTION

• The motor handpiece is designed with the commercially available AAA nickel metal hydride
batteries (rechargeable). Ni-Cad batteries can also be used, but the charging time and operating
time become significantly shorter since the charging current differs.
• The motor handpiece consumes electricity very slightly even when the power is off. In addition,
fully-charged rechargeable batteries, in general, discharge gradually over time even though it is
not used. It is recommended to recharge the batteries just before use.
• When the motor handpiece automatically stops by detecting a low battery voltage, leaving it for a
while and turning on the power again may not detect the low voltage immediately. This is not a
failure, but is due to battery characteristics. Since the voltage drop does not coincide with the
remaining battery capacity, consider it only as a yardstick.
• Recharge rechargeable batteries after they deplete as much as possible. Repeated short-time use
and subsequent recharging may shorten their operating time due to a "memory effect." Batteries
may recover after repeating complete discharge and full charge a few fimes.
• If you do not use the product for a long period of time, remove the batteries from the
motor handpiece.
NOTICE
• Compact body.
• Operable continuously for approx. one hour at rated load. (Dependent upon conditions.)
• Operation panel values are memorized.
• Normal operation of the motor handpiece includes pressing the switch turns on the handpiece
and re-pressing the switch turns it off. In addition, temporary operation is available : pressing
and holding the switch turns on the handpiece and releasing the switch turns it off.
• The motor handpiece softly starts.
• Energy savings. The power of the motor handpiece automatically turns off after 10 minutes of
non-use. (Auto power-off function)
• The battery lamp indicates low battery voltage.
• The built in feedback circuit keeps the rotation at a constant speed even when a load is applied to
the motor handpiece changes.
• The contra heads provided for this product are all autoclavable at 135ºC (excluding the motor
handpiece).

Caution
· Connect to AC120V power supply only. Voltage variation within ±10% is permissible.
Voltage beyond this range may result in damage.
· Never use the battery charger for anything other than the motor handpiece of the Hygiene
Pro Cordless.
· The charging normally takes approx. 90 minutes, but it depends on battery conditions,
battery freshness, ambient temperature, etc. Older batteries are especially prone to
significantly shorter charging and operating times.
· Batteries may slightly heat up during charging, but this is not a failure. If the handpiece is
inserted or removed into/from the charger at short intervals, (approx. 5 minutes) charging
cannot be properly completed and by touching the battery part you may feel heat.
We recommend that you charge batteries for as long a cycle as possible.
· If the motor handpiece is placed on the charger, it will not automatically power on if left on
the charger for more than 3 hours.
· The power of the motor handpiece should not be turned on immediately after removing
from the charger, wait approx. 2 seconds or longer with the power off.

6. Sterilization
1)Brush the dirt off the surface of the contra head, and wipe it off with a cotton cloth
moistened with rubbing alcohol. Do not use metal brush.
2)Lubricate the head with spray. (Refer to the "5. (1) Lubricating Contra Head.")
3)Insert the head into an autoclave pouch and seal it.
4)Autoclavable up to max. 275°F (135°C).
ex.) Autoclave for 20 min. at 250°F (121°C), or 15 min. at 270°F (132°C).
5)Keep the handpiece in the autoclave pouch to keep it clean until you use it.
Sterilize the contra head only. For sterilization, we recommend the autoclave sterilization
method. Sterilization is required first time you use and after each patient as noted below.
Autoclaving
• Do not heat sterilize the motor handpiece .
• Skip dry cycles as the temperature could exceed 275°F (135°C).
• Since the lowermost tray inside the chamber of the autoclave is close to a heater and the
temperature in that place may locally exceed 275°F (135°C), place the head on the central
or upper tray.
The motor handpiece monitors the temperature of the batteries. If the batteries become abnormally
hot, this system will automatically stop the motor handpiece. In such a case, wait until the motor
handpiece cools. If this safety system occurs repeatedly, either the batteries or motor handpiece is
not in the normal operating condition, contact Brasseler USA

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.
