BATTERY REMOVAL/INSTALLATION

1. Battery removal
Firmly support the power tool and remove the
battery while pushing the latch of the battery with
your thumb. (Fig. 2)
CAUTION:
Never short-circuit the battery.
Support the battery with your palm so that it does
not fall down.
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 the receptacle.
When the power cord is connected, the charger's
pilot lamp will blink in red. (At 1-second intervals.)

(2) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown
in Table 2.

NOTE: The charging time may vary according to ambient
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.
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

2. Insert the battery into the charger.
Position the battery so that the nameplate faces
toward the ventilation slots of the charger and push
in the battery unit it contacts the bottom plate. (See
Figs. 1 and 4.)
CAUTION:
If the battery is inserted in the reverse direction,
not only recharging will become impossible, but it
may also cause problems in the charger such as
a deformed recharging terminal.
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.
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.
Malfunction in the
battery or the charger
The battery temperature
is high, making
recharging impossible.
