The life of the battery pack terminals may
be affected by foreign substances such
as dust and water etc. during operation.
CAUTION: To protect the motor
or battery, be sure to
note the following when
carrying out operation.
If the battery becomes hot, the protection
● ●
function will be activated and the 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.
If the battery pack is not connected firmly
● ●
when the switch is switched on, the main
unit will not rotate normally. Connect the
battery pack into the body of the tool until
the red or yellow label disappears.
[Battery Charger]
Charging
CAUTION:
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.230v / 50Hz.
Do not attempt to use it on any other
● ●
voltage or frequency rating!
Do not use power source from an engine
● ●
generator.
If the temperature of the battery pack
● ●
falls approximately below −10°C (14°F),
charging will automatically stop to
prevent degradation of the battery.
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 tool may fail to function properly.
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.
Cool down the charger when charging
● ●
more than two battery packs consecutively.
Do not insert your fingers into contact
● ●
hole, when holding charger or any other
occasions.
CAUTION:
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.
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 warm (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 or less, charging takes longer
to fully charge the battery pack than
the standard charging time. Even
when the battery is fully charged, it will
have approximately 50% of the power
of a fully charged battery at normal
operating temperature.
