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.

Before using the impact driver, 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.
Insert the battery firmly, in the direction shown in Fig.
4, until it contacts the bottom of the charger
compartment.

(2) Regarding the temperatures of the rechargeable
battery.
The temperatures for rechargeable batteries are as
shown in the table below, 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.

Temperatures at
which the battery
can be recharged
–5°C – 60°C
0°C – 45°C
CAUTION
If the battery is inserted in the reverse direction, not
only recharging will become impossible, but it may
also cause the fuse to blow, or problems in the charger
such as 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.

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 charging, 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.
