Before Use; Maintenance And Inspection - Hitachi UC 18YGSL Manual De Instrucciones

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.
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.
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).
The battery will not be recharged. In such a case, let the battery cool before charging.
When the pilot lamp flickers (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.

BEFORE USE

Check the work area to make sure that it is clear of debris and clutter.
Clear the area of unnecessary personnel. Ensure that lighting and ventilation is adequate.
