Important Safety Instructions for
Battery Chargers
SAVE THESE INSTRUCTIONS - This manual contains important
safety instructions for D WALT battery chargers.
E
• Before using battery charger, read all instructions and cau-
tionary markings on battery charger, battery and product
using battery.
CAUTION: To reduce the risk of injury, charge only D
nickel cadmium rechargeable batteries. Other types of 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, 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.
DANGER: 120 volts are present at charging terminals. Do not
probe with conductive objects. Electric shock or electrocution
may result.
WARNING: Do not allow any liquid to get inside charger. Electric
shock may result.
• 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
WALT rechargeable batteries. Any other uses
E
may result in risk of fire, electric shock or electrocution.
• Pull by plug rather than cord when disconnecting charger.
This will reduce risk of damage to electric plug and cord.
• Make sure 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 an 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
WALT
E
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
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 a damaged cord or plug — have
them replaced immediately.
• Do not operate the 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
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.
