BATTERY REMOVAL/INSTALLATION

1. Battery removal

Hold the handle tightly and push the battery latch to remove the battery (see

Fig.

2

).

CAUTION:

Never short-circuit the battery.

2. Battery installation

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 until the line is visible, as shown in

Fig. 3, 4 

.

3. Charging

When inserting a battery in the charger, charging will commence and the

pilot lamp will light continuously in red.

When the battery becomes fully recharged, the pilot lamp will blink in red.

(At 1-second intervals) (See 

Table 1

)

(1) Pilot lamp indication

The indications of the pilot lamp will be as shown in 

Table 1

, according to

the condition of the charger or the rechargeable battery.

(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.

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

.

Approx. 45 min.

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.
