Important Charging Notes - DeWalt DW0242 Manual Del Usuario

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 slow-
ly lose its charge if left in a charger that is not plugged into an appro-
priate AC source.
WEAK BATTERY PACKS: Chargers can also detect a weak battery.
Such batteries are still usable but should not be expected to perform
as much work. In such cases, about 10 seconds after battery inser-
tion, the charger will beep rapidly 8 times to indicate a weak battery
condition. The charger will then go on to charge the battery to the high-
est capacity possible.
15 MINUTE CHARGERS
1. Plug the charger into an appropriate
power outlet. The charger will beep twice,
the red light will blink and go off.
2. Insert the battery pack into the charger, as
shown in FIG. 2, making sure the pack is
fully seated in the charger. The red light will
blink and the charger will beep once indi-
cating the charging process has started.
3. The battery pack will be fully charged in
less than 15 minutes under most conditions. This will be indicated
by the red light remaining ON and 3 beeps. The pack is fully
charged and may be used at this time or left in the charger.

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 tem-

shock may result. 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.

perature 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 prob-
lem.
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 or send the tool, battery pack
and charger to your local service center.
4. The battery pack should be recharged when it fails to produce suf-
ficient 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, 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: Don't allow any liquid to get inside charger. Electric
