CAUTION: Burn hazard. To reduce the risk of injury, charge only D
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.
• DO NOT attempt to charge the battery pack with any chargers other than the ones in
this manual. The charger and batter y pack are specifically designed to work together.
• These chargers are not intended for any uses other than charging D
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.
• When operating a power tool outdoors, 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
smaller the gauge number, the heavier the cord.

• 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.
• 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 120V household electrical power.
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 Automatic 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.
Chargers
Your tool uses a D
WALT 18-Volt or 24-Volt charger. Be sure to read all safety instructions
E
before using your charger. Consult the chart at the end of this manual for compatibility of
chargers and battery packs.
Fan Cooling (24 Volt Only)
The 24V charger is equipped with an internal fan that provides rapid cooling of D
battery packs. The fan operation is automatic and will turn on when required during battery
charging. This procedure is of great benefit for a pack that has finished a useable cycle. Place
the battery pack into the charger immediately after use so that the fan can cool the cells and
prolong the life of the battery pack.
WARNING: To minimize the risk of eye injury, always use eye protection. Fan may blow
debris from vent area at any time. Keep face and eyes away from area above vents.
Charging Procedure (Fig. 3)
DANGER: Electrocution hazard. 120 volts present at charging terminals. Do not probe with
conductive objects. Danger of electric shock or electrocution.
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.
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.
HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay feature: when the charger detects a battery that
is hot, it automatically starts a Hot Pack Delay, suspending charging until the battery has
cooled. After the battery has cooled, the charger automatically switches to the Pack Charging
mode. This feature ensures maximum battery life. The red light flashes long, then short while
in the Hot Pack Delay mode.
PROBLEM POWER LINE
Some chargers have a Problem Power Line indicator. When the charger is used with some
portable power sources such as generators or sources that convert DC to AC, the charger
may temporarily suspend operation, flashing the red light with two fast blinks followed by
a pause. This indicates the power source is out of limits.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the red light glowing indefinitely. The
charger will keep the battery pack fresh and fully charged.
NOTE: A battery pack will slowly lose its charge when kept out of the charger. If the battery
pack has not been kept on maintenance charge, it may need to be recharged before use.
A battery pack may also slowly lose its charge if left in a charger that is not plugged into an
appropriate AC source.
WEAK BATTERY PACKS: Chargers can also detect a weak battery pack. Such batteries
are still usable but should not be expected to perform as much work. The charger will indicate
to replace battery pack.
Important Charging Notes
1. Longest life and best performance can be obtained if the battery pack is charged when
the air temperature is between 65°F and 75°F (18°- 24°C). DO NOT charge the battery
pack in an air temperature below +40°F (+4.5°C), or above +105°F (+40.5°C). This is
important and will prevent serious damage to the battery pack.
2. The charger and battery pack may become warm to touch while charging. This is a
normal condition, and does not indicate a problem. To facilitate the cooling of the battery
pack after use, avoid placing the charger or battery pack in a warm environment such as
in a metal shed, or an uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check current at receptacle by plugging in a lamp or other appliance;
b. Check to see if receptacle is connected to a light switch which turns power off when
you turn out the lights;
c. Move charger and battery pack to a location where the surrounding air temperature is
approximately 65°F - 75°F (18°- 24°C);
d. If charging problems persist, take the tool, battery pack and charger to your local
service center.
4. The battery pack should be recharged when it fails to produce sufficient power on jobs
which were easily done previously. DO NOT CONTINUE to use under these conditions.
Follow the charging procedure. You may also charge a partially used pack whenever you
desire with no adverse affect on the battery pack.
5. Under certain conditions, with the charger plugged into 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, grinding dust, metal chips,
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.
6. Do not freeze or immerse charger in water or any other liquid.
WARNING: Shock hazard. Don't allow any liquid to get inside charger. Electric shock may
result.
CAUTION: 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.
Storage Recommendations
1. The best storage place is one that is cool and dry away from direct sunlight and excess
heat or cold.
2. Long storage will not harm the battery pack or charger. Under proper conditions, they can
be stored for 5 years or more.
