3. SAFETY PRECAUTIONS
• The battery is designed with full
attention paid to safety. If it does
not operate normally, or if you
notice any strange sounds or
offensive smells, stop using your
unit immediately.
• The lithium-ion battery does not
suffer from the memory effect❈, so
additional charging is possible.
❈(If the battery is charged
halfway before being completely
used (that is, the battery is
additionally charged halfway),
the apparent capacity of the
battery decreases, and the
battery quickly runs down.)
Overdischarging (state in which
the remaining battery life has
come to an end):
• If your unit is stored for a long time
without being used, the battery
might overdischarge due to self
discharging. The nature of a
battery is such that, if it is
overdischarged, it will stop working
as a battery. Even if you do not
use your unit, charge the battery
at least once every six months.
Criterion for Replacing Battery:
• The battery gradually deteriorates
through charging and discharging,
and its charging capability
gradually decreases. When it is
not possible to recover the battery
voltage (when the motor does not
rotate) even after charging the
battery for the prescribed time with
the charger associated with this
product, replace it with a new
battery. If it is difficult to judge how
to do this, contact the shop where
you bought your unit.
