metal objects that can make a connection
from one terminal to another.
Shorting the battery terminals together may
cause sparks, burns or a fire.
When operating the battery pack, make sure
the work place is well ventilated.
When the battery pack is removed from the
main unit, replace the battery pack cover
immediately in order to prevent dust or dirt
from contaminating the battery terminals and
causing a short circuit.
CAUTION:
To protect the motor or battery, be sure
to note the following when carrying out
operation.
If the motor and battery becomes hot, the
protection function will be activated and
the motor and battery will stop operating.
For safe use
• The battery pack is designed to be installed
by proceeding two steps for safety. Make
sure the battery pack is installed properly to
the main unit before use.
[Battery Charger]
Charging
CAUTION:
1) The charger is designed to operate on
standard domestic electrical power only
as stated in the rating plate. Charge only
on the voltage indicated on the rating
plate of unit. e.g.230 V/50 Hz.
2) Do not attempt to use it on any other
voltage or frequency rating!
3) If the temperature of the battery pack
falls approximately below -10°C (14°F),
charging will automatically stop to prevent
degradation of the battery.
4) The ambient temperature range is
between 0°C (32°F) and 40°C (104°F).
If the battery pack is used when the
battery temperature is below 0°C (32°F),
the unit may fail to function properly.
5) Use the charger at temperatures between
0°C (32°F) and 40°C (104°F), and charge
the battery at a temperature similar to
that of the battery itself. (There should be
no more than a 15°C (59°F) difference
between the temperatures of the battery
and the charging location.)
6) When charging a cool battery pack
(below 0°C (32°F)) in a warm place,
leave the battery pack at the place and
wait for more than one hour to warm up
the battery to the level of the ambient
temperature.
7) Cool down the charger when
charging more than two battery packs
consecutively.
8) Do not insert your fingers into contact
hole, when holding charger or any other
occasions.
9) To prevent the risk of fire or damage to
the battery charger.
Do not cover vent holes on the charger
and the battery pack.
Unplug the charger when not in use.
NOTE:
Your battery pack is not fully charged at
the time of purchase. Be sure to charge
the battery before use.
How to charge
1. Plug the charger into the AC outlet.
NOTE:
Sparks may be produced when the plug
is inserted into the AC power supply, but
this is not a problem in terms of safety.
2. Connect the battery pack firmly into the
charger.
1. Line up the alignment marks and place
the battery onto the dock on the charger.
2. Slide forward in the direction of the arrow.

marks
3. During charging, the charging lamp will be
illuminated. When charging is completed, an
internal electronic switch will automatically
be triggered to prevent overcharging.
Charging will not start if the battery pack is
hot (for example, immediately after heavy-
duty operation).
The orange standby lamp will be flashing
until the battery cools down. Charging will
then begin automatically.
4. The charge lamp (green) will flash slowly
once the battery is approximately 80%
charged.
5. When charging is completed, the charging
lamp in green color will turn off.
6. If the temperature of the battery pack is 0°C
(32°F) or less, charging takes longer to fully
charge the battery pack than the standard
charging time.
