Important Charging Notes; Air Cooling - DeWalt DW007 Instruction Manual

Important Charging Notes

1. Longest life and best performance can be obtained if the bat-
tery 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 indi-
cate a problem. To facilitate the cooling of the battery pack after
use, avoid placing the charger or battery pack in a warm envi-
ronment 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 charg-
er can be shorted by foreign material. Foreign materials of a
conductive nature such as, but not limited to, steel wool, alu-
minum 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. Do not allow any liquid to get inside
charger.
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.

Air Cooling

This charger is equipped with an internal fan that provides rapid
cooling of D WALT DW0242 battery packs. The fan operation is
E
automatic and will turn on when required during battery charging.
The fan will also cycle periodically when there is no battery in the
charger in order to blow dust from the fan vents.
Important!
The charger is not user serviceable. There are no user serviceable
parts inside the charger. Servicing at an authorized service center
is required to avoid damage to static sensitive internal components.
READ ALL OF THE INSTRUCTIONS IN THE BATTERY CHARG-
ER SECTION OF THIS MANUAL BEFORE ATTEMPTING TO
CHARGE THE BATTERY PACK FOR YOUR TOOL.
Always use correct battery pack (pack supplied with tool or replace-
ment pack exactly like it.) Never install any other battery pack. It will
ruin your tool and may create a hazardous condition.
