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, as shown in
Fig. 3.
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

BATTERY REMOVAL/INSTALLATION
1. Battery removal
Hold the housing tightly and push the battery latches 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).
(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.

0°C – 50°C
(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 3.

UC18YKSL UC18YFSL
BSL1415S, BSL1815S Approx. 35 min. Approx. 20 min.
BSL1425, BSL1825 Approx. 75 min. Approx. 35 min.
BSL1430, BSL1830 Approx. 90 min. 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 fi rmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after use,
and then keep it.
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 fi rst 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.
