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

The pilot lamp goes off to indicate that the battery
is fully charged.
The battery charging time becomes longer when a
temperature is low or the voltage of the power
source is too low.
When the pilot lamp does not go off even if more
than 120 minutes have elapsed after starting of the
charging, stop the charging and contact your
HITACHI AUTHORIZED SERVICE CENTER.
CAUTION
If the battery is heated due to direct sunlight,
etc., just after operation, the charger pilot lamp
may not light up. At that time, cool the battery
first, then start charging.
3. Disconnect the charger's power cord from the
receptacle
4. 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. 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.

Before using the power tool, charge the battery as
follows.
1. Connect the charger's power cord to the receptacle.
When connecting the plug of the charger to a
receptacle, the pilot lamp will blink in red
(At 1-second intervals).
2. Insert the battery into the charger.
Firmly insert the battery into the charger till it
contacts the bottom of the charger and checking
the polarities as shown in Fig. 4.
CAUTION
If the batteries are 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, the pilot
lamp will light up continuously in red.
When the battery becomes fully recharged, the pilot
lamp will blink in red (At 1-second intervals). (See
Table 3)
(1) Pilot lamp indication
The indications of the pilot lamp will be as shown
in Table 3, according to the condition of the charger
or the rechargeable battery.
