NOTICE
The symbol indicating the remaining amount of the batteries indicates a voltage. When load is applied to
the motor handpiece, the symbol indicating the remaining amount of the battery charge appears to be-
come lower.

5. Operations
(1) Charging Batteries
1. Insert the power cord jack into the inlet at the back of the battery charger. (Fig. 4)
2. Insert the power cord and plug in. Make sure you have the correct model/voltage.
3. Turn on the power switch. At this time, check that the power lamp lights up. (Fig. 5)
4. Insert the motor handpiece into the battery charge. Charging starts with the charge
mark flashing on LCD.
5. When the buzzer sounds and "

WARNING
When the buzzer does not sound and the charging animation is not displayed despite batteries being re-
placed with new ones, immediately stop using and contact your dealer. (Refer to Changing Batteries)
CAUTION
- When the power lamp for the charger does not light up, the internal fuse may be faulty. In this case
please contact your dealer.
- Be careful of handling when placing the motor handpiece in to the charger. Do not force the handpiece
into the charger. Otherwise, failure may be occur.
- If the power cord is inserted into the jack or the power switch is pressed with unnecessary force, the cord
or switch may be broken or a short-circuit may occur.
- Never use the battery charger for anything other than the motor handpiece of this product.
- The charging normally takes approx. 90 minutes, but it depends on battery use conditions, battery fresh-

ness, 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 not a failure. If the handpiece is inserted or
removed into/from the charger at short intervals, (approx. 5 minutes) charging cannot be properly com-
pleted and the battery compartment may feel hot. We recommend that you charge batteries for as long-
er periods as 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 place where temperature change is
minimal.
- Charging may not be started in the following case.
- The temperature of the batteries is excessively high or low. (Lower than approx. 0°C or higher
than approx. 40°C)
- Battery voltage is sufficient
- Battery voltage is abnormal
(2) Changing Contra Angle Head
The contra angle head can be connected with the mo-
tor handpiece at 6 adjustable head positions. Align the
positioning pins of the contra angle head with the posi-
tioning slots of the motor handpiece and insert the
head until they click. When removing the contra angle
head, pull it out axially.
CAUTION
- Turn OFF the power to remove or attach the contra angle head.
- Check that the contra angle head is securely connected to the motor handpiece.
