• 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
EWALT rechargeable batteries. Any other uses may result in risk of
fire, electric shock or electrocution.
• Do not expose charger to rain or snow.
• Pull by plug rather than cord when disconnecting charger. This will
reduce risk of damage to electric plug and cord.
• Make sure that 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.
• 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. 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 damaged cord or plug — have them
replaced immediately.
• Do not operate 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. Removing the
battery pack will not reduce this risk.
• NEVER attempt to connect 2 chargers together.
• The charger is designed to operate on standard household electrical
power (230 Volts). Do not attempt to use it on any other voltage. This
does not apply to the vehicular charger.
Using Automatic Tune-Up™ Mode
The automatic Tune-Up™ Mode equalizes or balances the individual cells
in the battery pack allowing it to function at peak capacity. Battery packs
should be tuned up weekly or after 10 charge/discharge cycles or whenever
the pack no longer delivers the same amount of work. To use the automatic
Tune-Up™, place the battery pack in the charger and leave it for at least 8
hours. The charger will cycle through the following modes.
1. The red light will blink continuously indicating that the
1-hour charge cycle has started.
2. When the 1-hour charge cycle is complete, the light will stay on
continuously and will no longer blink. This indicates that the pack is
fully charged and can be used at this time.
3. If the pack is left in the charger after the initial 1-hour charge, the
charger will begin the Automatic Tune-Up mode. This mode continues
up to 8 hours or until the individual cells in the battery pack are
equalized. The battery pack is ready for use and can be removed at
any time during the Tune-Up mode.
4. Once the Automatic Tune Up mode is complete, the charger will begin
a maintenance charge; the red indicator will remain lit.

FOR FUTURE USE
Chargers
Your tool uses a DEWALT Charger. Your battery can be charged in DEWALT
1 Hour Chargers, 15 Minute Chargers or Vehicular 12 volt charger. Be sure
to read all safety instructions before using your charger. Consult the chart
on the back cover of this manual for compatibility of chargers and battery
packs.
15 MINUTE
CHARGER
FIG. 2
1 HOUR CHARGER
Charging Procedure
DANGER: Electrocution hazard. 230 volts are present at charging
terminals. Do not probe with conductive objects.
1. Plug the charger into an appropriate outlet before inserting battery
pack.
2. Insert the battery pack into the charger. The red (charging) light will
blink continuously indicating that the charging process has started
(Fig. 2).
3. The completion of charge will be indicated by the red light remaining ON
continuously. The pack is fully charged and may be used at this time or
left in the charger.
Indicator Light Operation
Charge Indicators
Some chargers are designed to detect certain problems that can arise with
battery packs. Problems are indicated by the red light flashing at a fast
rate. If this occurs, re-insert battery pack into the charger. If the problem
persists, try a different battery pack to determine if the charger is OK. If the
new pack charges correctly, then the original pack is defective and should
be returned to a service center or other collection site for recycling. If the
new battery pack elicits the same trouble indication as the original, have
the charger tested at an authorized service center.
NOTE: Battery storage and carrying caps are provided
for use whenever the battery is out of the tool or charger.
Remove cap before placing battery in charger or tool.
WARNING: Fire hazard. Do not store or carry battery
so that metal objects can contact exposed battery
terminals. For example, do not place battery in aprons,
pockets, tool boxes, product kit boxes, drawers, etc.,
with loose nails, screws, keys, etc. without battery cap.
Transporting batteries can possibly cause fires if the battery terminals
inadvertently come in contact with conductive materials such as keys,
coins, hand tools and the like. The US Department of Transportation
Hazardous Material Regulations (HMR) actually prohibit transporting
batteries in commerce or on airplanes (i.e., packed in suitcases and
carry-on luggage) UNLESS they are properly protected from short circuits.
So when transporting individual batteries, make sure that the battery
terminals are protected and well insulated from materials that could contact
them and cause a short circuit.
CAUTION: Battery pack must be securely attached to tool. If battery pack
is detached, personal injury may result.
The RBRC™ Seal
The RBRC™ (Rechargeable Battery Recycling Corp oration)
Seal on the nickel cadmium and nickel metal hydride
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 DEWALT. In some
areas, it is illegal to place spent nickel cadmium and nickel
metal hydride 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 and nickel metal hydride batteries. Help
protect our environment and conserve natural resources by returning the
spent nickel cadmium and nickel metal hydride batteries to an authorized
D
EWALT 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.

Important Safety Instructions for Battery Chargers
SAVE THESE INSTRUCTIONS: This manual contains important safety
instructions for battery chargers.
• Before using charger, read all instructions and cautionary markings on
charger, battery pack, and product using battery pack.
DANGER: Electrocution Hazard. 230 Volts are present at charging
terminals. Do not probe with conductive objects. Electric shock or
electrocution may result.
WARNING: Shock Hazard. Do not allow any liquid to get inside charger.
Electric shock may result.
CAUTION: Burn Hazard. To reduce the risk of injury, charge only
DEWALT 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, aluminum 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.
