Storage Recommendations; Intended Use - DeWalt DCF894H Instruction Manual

English
the battery pack in an air temperature below +40 °F
(+4.5 °C), or above +104 °F (+40 °C). This is important
and will prevent serious damage to the battery pack.
2. The charger and battery pack may become warm to the
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 operation of 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 the 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 effect on the battery pack.
5. 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 the charger
before attempting to clean.
6. Do not freeze or immerse the charger in water or any
other liquid.

Storage Recommendations

1. The best storage place is one that is cool and dry, away
from direct sunlight and excess heat or cold.
2. For long storage, it is recommended to store a fully
charged battery pack in a cool dry place out of the
charger for optimal results.
nOTE: Battery packs should not be stored completely
depleted of charge. The battery pack will need to be
recharged before use.
