3. Charging
When inserting a battery in the charger, the charge
indicator lamp will blink in blue.
When the battery becomes fully recharged, the charge
indicator lamp will light up in green. (See Table 2)
(1) Charge indicator lamp indication
The indications of the charge indicator lamp will be
as shown in Table 2, according to the condition of the
battery charger or the battery.

*1 If the red lamp continues to blink even after the
charger has been attached, check to confi rm that the
battery has been fully inserted.
*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 confi 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.
(2) Regarding the temperature of the rechargeable
battery.
The temperatures for rechargeable batteries are
as shown in the Table 3, and batteries that have
become hot should be cooled for a while before being
recharged.

NOTE
The recharging time may vary according to the
ambient temperature.
4. Disconnect battery charger from the receptacle.
CAUTION
2
Do not pull the plug out of the receptacle by pulling
on the cord.
Make sure to grasp the plug when removing from
receptacle to avoid damaging cord.
5. Remove the battery from the battery charger.
Supporting the battery charger with hand, pull out the
battery from the battery charger.
NOTE
Be sure to pull out the battery from the battery 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.
