battery.
The temperatures and charging time will become as
shown in Table 2.

NOTE
The recharging time may vary according to the ambient
temperature and power source voltage.
In addition, the charge time becomes signifi cantly long in
a low temperature environment, but this is not abnormal.
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.

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, according to the condition of the charger or the
rechargeable battery.

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.
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 (off 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 confi 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 30 seconds 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.
