[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!

• If the temperature of the battery pack

falls approximately below −10°C (14°F),

charging will automatically stop to pre-

vent 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 bat-

tery temperature is below 0°C (32°F), the

tool may fail to function properly.

• Use the charger at temperatures

between 0°C and 40°C, and charge

the battery at a temperature similar to

that of the battery itself. (There should

be no more than a 15°C difference

between the temperatures of the bat-

tery and the charging location.)

• 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 con-

tact 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 char-

ger 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.

3. During charging, the charging lamp will

be Illuminated.

When charging is completed, an inter-

nal electronic switch will automatically

be triggered to prevent overcharging.

• Charging will not start if the battery

pack is warm (for example, immedi-

ately after heavy-duty operation).

The orange standby lamp will be

flashing until the battery cools down.

Charging will then begin automati-

cally.

4. The charge lamp (green) will flash

slow ly once when the battery is ap-

proxi mately 80% charged.

5. When charging is completed, the charg-

ing 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 nor-

mal operating temperature.

7. Consult an authorized dealer if the

charging lamp (green) does not turn off.

8. If a fully charged battery pack is in-

serted into the charger again, the

charging lamp lights up. After several

minutes, the charging lamp in green

color will turn off.

9. Remove the battery pack while the

battery pack release button is held up.
