NOTICE: Under certain conditions, with the charger plugged into the
power supply, the charger can beshorted byforeign material Foreign
materials ofaconductive nature, such as,butnotlimited t o,grinding
dust, m etal chips, steel wool, aluminum foil o rany buildup ofmetallic
particles should bekept away f rom the charger cavities. Always unplug
the charger from the power supply when t here i snobattery pack i nthe
cavity, Unplug the charger before attempting toclean.
• 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
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 heal 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 orplug.
• Do not operate the charger if it has received a sharp blow,
been dropped or otherwise damaged in any way. Takeit to an
authorized service center.
• Do not disassemble the 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.
