Class II equipment
• This product does not consider patient’s age (except infants), gender, weight or nationality.
• The motor handpiece is designed for 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 due to battery characteristics. The voltage drop does not coincide
with the remaining battery capacity.
• Recharge rechargeable batteries after they deplete as much as possible. Repeating short
time use and subsequent recharging may shorten their operating time due to a “memory
effect.” Batteries may recover from the memory effect after fully discharging and then fully
charging and repeating this procedure a few times.
• Eventually completely discharged batteries cannot be charged and need to be replaced.
• User shall be responsible for operation, maintenance and operation.
• No special training is required for this device.

• The charging normally takes approx. 90 minutes, but it depends on battery use
conditions, battery freshness, ambient temperature, etc. Older batteries are especially
prone to significantly shorter charging and operating times.
• Batteries may slightly warm up during charging, but this is normal. If the handpiece is
inserted or removed into/from the charger at short intervals, (approx. 5 minutes)
charging cannot be properly completed and the battery compartment may feel hot.
We recommend that you charge batteries for longer periods if possible.
• The power of the motor handpiece should not be turned on immediately after it has
been removed from the charger, wait at least approx. 2 seconds before you switch on
the power.
• Completely discharged batteries cannot be charged. Replace them with new ones.
• Do not put anything (metal or other devices such as wire, safety pin, or coin) other
than the handpiece on the charger. Otherwise, burn or failure may result due to heat
generation.
• The temperature of the batteries is measured during charging. Proper charging cannot
be performed if the charger is placed in an environment which is subject to sharp
temperature change (next to window, subject to direct sunlight, near air outlet or fan
heater). Place it in a location where temperature change is minimal.
• Charging may not start in the following case.
 The temperature of the batteries is excessively high or low.

(rotation speed, torque limit value, gear ratio and auto reverse mode)
1. Press the PROGRAM key until it turns to the program number which you want to have
memorized.
2. Adjust the rotation speed, torque limit value, gear ratio and auto reverse mode by
UP/DOWN key according to your needs.
3. Hold down the PROGRAM key for more than one second. When the alarm sounds the
settings have been memorized.
(2) Calibration
This function is to decrease fluctuation in the rotation speed of the motor handpiece and the
difference in torque by the contra angle head.
1. Lubricate the contra angle head with BRASSELER USA SPRAY).
(Refer to the “7 (1) Lubricating Contra Angle Head.”)
2. Turn on the power.
3. Hold down UP/DOWN key simultaneously for more than one second.

the rotating shaft will impair correct measurement.
• Do not touch or apply a load to the rotating shaft of the contra angle head. It will
obstruct accurate measurement.
• This function cannot completely detect the individual difference of the actual motor
handpiece and contra angle head.
The volume setting is memorized automatically to the last setting and remains
unchanged even if the power is turned off.
