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.
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.

BSL1430, BSL1830 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.
