IMPORTANT SAFETY INSTRUCTIONS FOR ALL BATTERY CHARGERS
SAVE THESE INSTRUCTIONS: This manual contains important safety and
operating instructions for battery chargers.
• Before using the charger, read all instructions and cautionary markings
on the charger, battery pack and product using the battery pack.
WARNING: Shock hazard. Do not allow any liquid to get inside the char-
ger. Electric shock may result.
WARNING: Burn hazard. To reduce the risk of injury, charge only DEWALT
rechargeable battery packs.
CAUTION: 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 un-plug the charger from the power
supply when there is no battery pack in the cavity. Unplug the charger before
attempting to clean it.
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
DeWALT 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 Ameri‑
can 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 rat-
ing. 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.
