*2 Although charging will start once the battery has cooled
down even when left in situ, the best practice is to
remove the battery and allow it to cool down in a shaded,
well-ventilated location before charging.
*3
○ Fully insert the battery.
○ Check to con fi rm that no foreign matter is stuck to the
battery mount or terminals.
<If charging takes a long time>
○ Charging will take longer at extremely low ambient
temperatures. Charge the battery in a warm location
(such as indoors).
○ Do not block the air vent. Otherwise the interior will
overheat, reducing the charger’s performance.
○ If the cooling fan is not operating, contact a HiKOKI
Authorized Service Center for repairs.

NOTE
The recharging time may vary according to the ambient
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.
(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 charge indicator lamp of the charger lights
for 0.3 seconds, does not light for 0.3 seconds (o ff for
0.3 seconds). In such a case, fi rst let the battery cool,
then start charging.
○ When the charge indicator 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
