Use and Care Manual
WARNING: Shock hazard. Do not allow any liquid to get inside the 
charger. Electric shock may result.
CAUTION: Burn hazard. To reduce the risk of injury, charge only 
D
EWALT rechargeable battery packs. Other types of batteries may 
overheat and burst resulting in personal injury and property damage.
NOTICE: Under certain conditions, with the charger plugged into the 
power supply, 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 the 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.
WARNING:
•  DO NOT attempt to charge the battery pack with any 
chargers other than the ones in this manual. The charger and 
battery pack are specifically designed to work together. 
•  These chargers are not intended for any uses other than 
charging D
EWALT rechargeable batteries. Any other uses 
may result in risk of fire, electric shock or electrocution.
•  Do not expose the charger to rain or snow.
•  Pull by the plug rather than the cord when disconnecting 
the charger. This will reduce the risk of damage to the electric 
plug and cord.
•  Make sure that the cord is located so that it will not be 
stepped on, tripped over or otherwise subjected to damage 
or stress.
•  Do not use an extension cord unless it is absolutely 
necessary. Use of improper extension cord could result in risk of 
fire, electric shock or electrocution.
•  When operating a charger outdoors, always provide a dry 
location and use an extension cord suitable for outdoor 
use. Use of a cord suitable for outdoor use reduces the risk of 
electric shock. 
•  An extension cord must have adequate wire size (AWG or 
American Wire Gauge) for safety. The smaller the gauge number 
of the wire, the greater the capacity of the cable, that is, 16 gauge 
has more capacity than 18 gauge. An undersized cord will cause a 
drop in line voltage resulting in loss of power and overheating. When 
using more than one extension to make up the total length, be sure 
each individual extension contains at least the minimum wire size. 
The following table shows the correct size to use depending on 
cord length and nameplate ampere rating. If in doubt, use the next 
heavier gauge. The lower the gauge number, the heavier the cord.

•  Do not place any object on top of the charger or place the 
charger on a soft surface that might block the ventilation 
slots and result in excessive internal heat. Place the charger 
in a position away from any heat source. The charger is ventilated 
through slots in the top and the bottom of the housing.
•  Do not operate the charger with a damaged cord or plug.
