Important Safety Instructions for Battery
Chargers
SAVE THESE INSTRUCTIONS: This manual contains important
safety instructions for battery chargers.
• Before using charger, read all instructions and cautionary markings
on charger, battery pack, and product using battery pack.
DANGER: Electrocution hazard. 120 volts are present at charging
terminals. Do not probe with conductive objects. Electric shock or
electrocution may result.
WARNING: Shock hazard. Do not allow any liquid to get inside
charger. Electric shock may result.
CAUTION: Burn hazard. To reduce the risk of injury, charge only
D
EWALT nickel cadmium rechargeable batteries. Other types of bat-
teries may burst causing personal injury and damage.
CAUTION: Under certain conditions, with the charger plugged in to
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 cavi-
ties. Always unplug the charger from the power supply when there is
no battery pack in the cavity. Unplug charger before attempting to
clean.
• 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 charger to rain or snow.
• Pull by plug rather than cord when disconnecting charger.
This will reduce risk of damage to electric plug and cord.
• Make sure that 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 neces-
sary. Use of improper extension cord could result in risk of fire,
electric shock, or electrocution.
• 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. When using more than one
extension to make up the total length, be sure each individual
extension contains at least the minimum wire size.

• Do not place any object on top of charger or place the charg-
er 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 charger with damaged cord or plug — have
them replaced immediately.
• Do not operate charger if it has received a sharp blow, been
dropped, or otherwise damaged in any way. Take it to an autho-
rized service center.
• Do not disassemble charger; take it to an authorized service
center when service or repair is required. Incorrect reassembly
may result in a risk of electric shock, electrocution or fire.
• Disconnect the charger from the outlet before attempting any
cleaning. This will reduce the risk of electric shock. Removing
the battery pack will not reduce this risk.
• NEVER attempt to connect 2 chargers together.
• The charger is designed to operate on standard household
electrical power (120 Volts). Do not attempt to use it on any
other voltage. This does not apply to the vehicular charger.
