CHARGING
Before using the power tool, charge the battery as follows.
1. Connect the charger's power cord to the receptacle.
2. Insert the battery into the charger. (Fig. 2)
Insert the battery fi rmly while observing its direction, until
it contacts the bottom of the charger (the pilot lamp lights
up).
CAUTION
○ If the pilot lamp does not light up, pull out the power
cord from the receptacle and check the battery
mounting condition.
○ 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 fi rst, then start
charging.
● Regarding the temperatures and charging time of the
battery.
The temperatures and charging time will become as

NOTE
The recharging time may vary according to the ambient
temperature and power source voltage.
CAUTION
○ Always charge the battery at a temperature of 10°C –
40°C. A temperature of less than 10°C will result in over
charging which is dangerous. The battery cannot be
charged at a temperature higher than 40°C.
○ When one charging is completed, leave the charger for
about 15 minutes before the next charging of battery.
○ 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 HiKOKI AUTHORIZED
SERVICE CENTER.
3. The pilot lamp goes off to indicate that the battery is
fully charged.
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.
