CAUTION
14
• When the power lamp for the charger does not light up, the internal fuse may be faulty.
In this case please contact Brasseler USA.
• Be careful when placing the motor handpiece in to the charger. Do not force the
handpiece into the charger. Otherwise, failure may 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 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.
(Lower than approx. 0°C or higher than approx. 40°C)
 Battery voltage is sufficient
 Battery voltage is abnormal
