Prior To Operation - HIKOKI DS 18DA Handling Instructions Manual

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.
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
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.
○ 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
5 minutes 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.
