3. Charging
◯When the plug of battery charger has been inserted into the receptacle, charging will commence and the pilot lamp will light on.
NOTE: If the pilot lamp does not light, pull out the plug from the receptacle and check if the battery is properly mounted.
◯In approx. one hour, when the battery is fully charged, the pilot lamp will go out.
NOTE: ◯ The battery charging time becomes longer when a temperature is low or the voltage of the power source is too low.
When the pilot lamp does not go off even if more than four hour has passed after start of the charging, stop the charging and contact your HITACHI AUTHORIZED SERVICE CENTER.
◯The UC 14SD is a charger to be used exclusively for the EB1414 battery. Avoid charging batteries with the charger other than the EB1414 battery. While it is possible to insert the 7.2V, 9.6V, 12V and 24V batteries into the charger lighting up the pilot lamp, please note that no charging can be made.
4. Disconnect battery charger from the receptacle.
CAUTION:
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.
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 first 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.
◯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.
◯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.
