Important Safety Instructions for All
Battery Chargers

WARNING:
and all instructions for the battery pack, charger
and power tool. Failure to follow the WARNINGs
and instructions may result in electric shock, fire
and/or serious injury.
• 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.
e
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.

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 the charger with a damaged cord
•
or plug.
• 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 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.
• 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
120V household electrical power. Do not attempt to
use it on any other voltage. This does not apply to the
vehicular charger.

WARNING:
any liquid to get inside the charger. Electric shock
may result.

WARNING:
submerge the battery pack in any liquid or allow any
liquid to enter the battery pack. Never attempt to open
the battery pack for any reason. If the plastic housing
of the battery pack breaks or cracks, return to a service
center for recycling.

CAUTION:
of injury, charge only D
packs. 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 unplug
the charger from the power supply when there is no
battery pack in the cavity. Unplug the charger before
attempting to clean.
