CAUTION

Never short-circuit the battery.

2.Battery installationInsert 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.

(3)Regarding recharging time

Depending on the combination of the charger and batteries, the charging time will become as shown in Table 3.

BSL1430, BSL1830

Approx. 45 min.

 

 

BSL1440, BSL1840

Approx. 60 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.

(2)Avoid recharging at high temperatures.

A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.
