SAVE THESE INSTRUCTIONS:
This manual contains important safety and operating instruc-
tions for battery chargers.
•
Before using charger, read all instructions and cautionary markings on charger, battery pack,
and product using battery pack.
_&DANGER: Electrocution hazard. 120 volts are present at charging terminals. Do not probe
with conductive objects. Electric shock or electrocution
may result.
i_ WARNING: Shock hazard. Do not allow any liquid to get inside charger. Electric shock may
result.
i_ CAUTION: Burn hazard. To reduce the risk of injury, charge only DEWALT rechargeable
batteries. Other types of batteries may burst causing personal injury and damage.
i_ 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 battery pack are specifically designed to work together.
•
These chargers are not intended for any uses other than charging DEWALTrechargeable
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.
•
Do not operate charger
ff 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
TM
Mode
The automatic Tune-Up
TM
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
TM,
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.
Chargers
Your tool uses a DEWALT 7.2, 9.6, 12, 14.4, 18 Volt charger. Be sure to read all safety
instructions
before using your charger.
Consult the chart at the end of this manual for
compatibility of chargers and battery packs.

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, 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.
i_ 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.

_, CAUTION: Ensure fastener and/or system will withstand the level of torque generated by the
tooL Excessive torque may cause breakage and possible personal injury,
1. Place the socket on the fastener head. Keep the tool pointed straight at the fastener.
2. Press switch to start operation. Always check torque with a torque wrench, as the fastening
torque is affected by many factors including the following:
•
Voltage: Low voltage, due to a nearly discharged battery, will reduce fastening torque.
• Socket size: Failure to use the correct socket size will cause a reduction in fastening
torque.
• Bolt Size: Larger bolt diameters generally
require higher fastening torque. Fastening
torque will also vary according to length, grade, and torque coefficient.
• Bolt: Ensure that all threads are free of rust and other debris to allow proper fastening
torque
• Material'.
The type of material and surface finish of the material will affect fastening
torque.
• Fastening
Time: Longer fastening time results in increased fastening torque. Using a
longer fastening time than recommended
could cause the fasteners to be overstressed,
stripped or damaged.
