CHARGING
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 charge indicator lamp will blink in red (At 1- second
intervals).
2. Insert the battery into the charger.
Firmly insert the battery into the charger as shown in
Fig. 3.
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 1)
(1) Charge indicator lamp indication
The indications of the charge indicator lamp will be as
shown in Table 1, according to the condition of the
charger or the rechargeable 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.

○ 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.

NOTE
The recharging time may vary according to the ambient
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.
