Insert the battery while observing its polarities (see

Fig. 2

CHARGING

Before using the power tool, charge the battery as follows.

1. Connect the charger’s power cord to a receptacle.

When the power cord is connected, the charger’s
pilot lamp will blink in red. (At 1-second intervals)

2. Insert the battery into the charger.

Firmly insert the battery into the charger till it contacts
the bottom of the charger and checking the polarities
as shown in

Fig. 3

(2) Regarding the temperatures of the rechargeable

battery
The temperatures for rechargeable batteries are as
shown in

Table 2

, and batteries that have become

hot should be cooled for a while before being
recharged.

Table 2

Recharging ranges of batteries

(3) Regarding recharging time

Depending on the combination of the charger and
batteries, the charging time will become as shown in

Table 3

Charging time (At 20°C)

NOTE:

The charging time may vary according to temperature
and power source voltage.

4. Disconnect the charger’s power cord from the

receptacle.

5. Hold the charger firmly and pull out the battery.
NOTE:

After operation, pull out batteries from the charger
first, and then keep the batteries properly.

Regarding electric discharge in case of new
batteries, etc.

As the internal chemical substance of new batteries
and batteries that have not been used for an extended
period is not activated, the electric discharge might
be low when using them the first and second time.
This is a temporary phenomenon, and normal time
required for recharging will be restored by recharging
the batteries 2-3 times.

How to make the batteries perform longer

(1) Recharge the batteries before they become completely

exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
