Important Charging Notes; Storage Recommendations - DeWalt DCD930 Manual De Instrucciones

PROBLEM POWER LINE
Some chargers have a Problem Power Line indicator. When
the charger is used with some portable power sources such as
generators or sources that convert DC to AC, the charger may
temporarily suspend operation, flashing the red light with two
fast blinks followed by a pause. This indicates the power source
is out of limits.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the red
light glowing indefinitely. The charger will keep the battery pack
fresh and fully charged.
NOTE: A battery pack will slowly lose its charge when kept out of
the charger. If the battery pack has not been kept on maintenance
charge, it may need to be recharged before use. A battery pack
may also slowly lose its charge if left in a charger that is not plugged
into an appropriate AC source.
WEAK BATTERY PACKS: Chargers can also detect a weak
battery pack. Such batteries are still usable but should not be
expected to perform as much work. The charger will indicate to
replace battery pack.

Important Charging Notes

1. Longest life and best performance can be obtained if the battery
pack is charged when the air temperature is between 65°F and
75°F (18°- 24°C). DO NOT charge the battery pack in an air
temperature below +40°F (+4.5°C), or above +105°F (+40.5°C).
This is important and will prevent serious damage to the battery
pack.
2. The charger and battery pack may become warm to touch while
charging. This is a normal condition, and does not indicate a
problem. To facilitate the cooling of the battery pack after use,
avoid placing the charger or battery pack in a warm environment
such as in a metal shed, or an uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check current at receptacle by plugging in a lamp or other
appliance;
b. Check to see if receptacle is connected to a light switch
which turns power off when you turn out the lights;
c. Move charger and battery pack to a location where the
surrounding air temperature is approximately 65°F - 75°F
(18°- 24°C);
d. If charging problems persist, take the tool, battery pack and
charger to your local service center.
4. The battery pack should be recharged when it fails to produce
sufficient power on jobs which were easily done previously.
DO NOT CONTINUE to use under these conditions. Follow
the charging procedure. You may also charge a partially used
pack whenever you desire with no adverse affect on the battery
pack.
5. Under certain conditions, with the charger plugged into the
power supply, the exposed charging contacts inside the charger
can be shorted by foreign material. Foreign materials of a
conductive nature such as, but not limited to, grinding dust,
metal chips, steel wool, aluminum foil, or any buildup of metallic
particles should be kept away from charger cavities. Always
unplug the charger from the power supply when there is no
battery pack in the cavity. Unplug charger before attempting to
clean.
6. Do not freeze or immerse charger in water or any other liquid.
WARNING: Shock hazard. Don't allow any liquid to get inside
charger. Electric shock may result.
CAUTION: Never attempt to open the battery pack for any
reason. If the plastic housing of the battery pack breaks or cracks,
return to a service center for recycling.

Storage Recommendations

1. The best storage place is one that is cool and dry away from
direct sunlight and excess heat or cold.
