Before Use; Prior To Operation - Hitachi DH 25DAL Manual De Instrucciones

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.

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.
