2. Insert the battery into the charger.
Firmly insert the battery into the charger as shown in
Fig. 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
)
●
Pilot lamp indication
The indications of the pilot lamp will be as shown in
Table 1

NOTE
The recharging time may vary according to temperature
and power source voltage.
CAUTION
When the battery charger has been continuously used,
the battery charger will be heated, thus constituting
the cause of the failures. Once the charging has been
completed, give 15 minutes rest until the next charging.
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.
(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.
CAUTION
○
If the battery is charged while it is heated because it has
been left for a long time in a location subject to direct
sunlight or because the battery has just been used, the
pilot lamp of the charger lights for 1 second, does not
light for 0.5 seconds (o
ff
for 0.5 seconds). In such a case,
fi
rst let the battery cool, then start charging.
○
When the pilot lamp
fl
ickers (at 0.2-second intervals),
check for and take out any foreign objects in the charger’s
battery connector. If there are no foreign objects, it is
probable that the battery or charger is malfunctioning.
Take it to your authorized Service Center.
○
Since the built-in micro computer takes about 3
seconds to con
fi
rm that the battery being charged with
charger is taken out, wait for a minimum of 3 seconds
before reinserting it to continue charging. If the battery
is reinserted within 3 seconds, the battery may not be
properly charged.
○
If the pilot lamp does not blink in red (every second)
even though the charger cord is connected to the power,
it indicates that the protection circuit of the charger may
be activated.
Remove the cord or plug from the power and then
connect it again after 5 minutes or so. If this does not
cause the pilot lamp to blink in red (every second),
please take the charger to the HiKOKI Authorized
Service Center.
