Specific Safety Instructions for the
USB Ports
• Do not insert foreign objects into the USB Ports.
• Do not attach USB hubs or more than one personal electronic
device to each USB Port.
• Do not use this unit to operate appliances that require more than
2.1 amps in total to operate from the USB Ports.
• Some household USB-powered electronics will not operate with
this unit.
The RBRC™ Seal
The RBRC™ (Rechargeable Battery Recycling Corporation) Seal on
the nickel cadmium, nickel metal hydride or lithium ion batteries (or
battery packs) indicate that the costs to recycle these batteries (or
battery packs) at the end of their useful life have already been paid by
D
WALT. In some areas, it is illegal to place spent
e
nickel cadmium, nickel metal hydride or lithium ion
batteries in the trash or municipal solid waste stream
and the RBRC program provides an environmentally
conscious alternative.
RBRC™, in cooperation with DeWALT and other battery users, has
established programs in the United States and Canada to facilitate the
collection of spent nickel cadmium, nickel metal hydride or lithium ion
batteries. Help protect our environment and conserve natural resources
by returning the spent nickel cadmium, nickel metal hydride or lithium
ion batteries to an authorized DeWALT service center or to your local
retailer for recycling. You may also contact your local recycling center
for information on where to drop off the spent battery.
RBRC™ is a registered trademark of the Rechargeable Battery
Recycling Corporation.

Important Safety Instructions for All
D
WALT
20V Battery Pack Chargers
®
e
(not included)
IMPORTANT: Before using the charger, read all instructions and
warnings included with the charger and the battery pack.
WARNING –
Shock hazard: Do not allow any liquid to get inside
the charger. Electric shock may result.
CAUTION –
Burn hazard: To reduce the risk of injury, charge only
D
WALT rechargeable battery packs. Other types of batteries may
e
overheat and burst resulting in personal injury and property damage.
NOTICE:
Always unplug the charger from the power supply when
there is no battery pack in the cavity. Unplug the charger before
attempting to clean.
• 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 may result in risk of
e
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 to 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.
• An extension cord must have adequate wire size (AWG) for safety.
The smaller the gauge number of the wire, the greater the capacity
6
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. 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.

Not Recommended
• 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.
• 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.
• Do not disassemble the charger. 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 two chargers together.
• The charger is designed to operate on standard 120V household
electrical power. Do not attempt to use it on any other voltage.
Personal Precautions
• Consider having someone close enough by to come to your aid
when you work near a lead-acid battery.
• Wear complete eye protection and clothing protection. Avoid
touching eyes while working near battery.
• Have plenty of fresh water and soap nearby in case battery acid
contacts skin, clothing, or eyes.
• Remove personal metal items such as rings, bracelets, necklaces
and watches when working with a lead acid battery. A lead acid
battery can produce a short circuit current high enough to weld a
ring, or similar metal object, to skin causing a severe burn.
• If battery acid contacts skin or clothing, wash immediately with
soap and water. If acid enters eye, immediately flood eye with
running cold water for at least 10 minutes and get medical
attention immediately.
• NEVER smoke or allow a spark or flame in vicinity of battery or
engine.
• Be extra cautious to reduce risk of dropping a metal tool onto
battery. It might spark or short-circuit battery or other electrical part
that may cause explosion.
Important Notes:
Several factors can affect a charger's ability to charge a vehicle's
battery, including, but not limited to, the size of the vehicle battery, the
temperature (hot or cold), whether the battery is damaged or defective,
and whether the D
WALT
20V Battery Pack is fully charged.
