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 mark-
ings on charger, battery pack, and product using battery pack.
DANGER: Electrocution hazard. 120 volts are present at charg-
ing 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 WALT nickel cadmium rechargeable batteries. Other types of
E
batteries 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 cavities. 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 charg-
ers other than the ones in this manual. The charger and bat-
tery pack are specifically designed to work together.
• These chargers are not intended for any uses other than
charging D WALT rechargeable batteries. Any other uses
E
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
charger on a soft surface that might block the ventilation
slots and result in excessive internal heat. Place the charg-
er in a position away from any heat source. The charger is ven-
tilated 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
authorized service center.
• Do not disassemble charger; take it to an authorized service
center when service or repair is required. Incorrect reassem-
bly may result in a risk of electric shock, electrocution or fire.
