• 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.

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

D

EWALT 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.

• 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.

• 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 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

English

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 Tune­Up™, 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 Tune­Up™ 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 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.

Charging Procedure

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, making sure the pack
is fully seated. 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

6

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

7

English

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,

English

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.

error into your measurements.

• To increase working distance and accuracy, set up the laser in
the middle of your working area.

• When attaching to a tripod or wall, mount the laser securely.

• When working indoors, a slow rotary head speed will produce
a visibly brighter line, a faster rotary head speed will produce a
visibly solid line.

• To increase beam visibility, wear Laser Enhancement Glass es
and/or use a Laser Target Card to help find the beam.

• Extreme temperature changes can cause movement or shifting
of building structures, metal tripods, equipment, etc., which can
effect accuracy. Check your accuracy often while working.

• When working with the D
laser’s rotation speed to the fastest setting.

• If the laser is dropped or has suffers a sharp blow, have the
calibration system checked by a qualified service center before
using the laser.

Using the Laser on a Tripod

1. Position the tripod securely and set it to the desired height.

2. Make sure that the top of the tripod is roughly level. The laser
will self-level only if the top of the tripod is within ± 5˚ of level. If
the laser is set up too far out of level, it will beep when it reaches
the limit of its leveling range. No damage will be done to the
laser, but it will not operate in an “out of level” condition.

3. Secure the laser to the tripod by screwing the threaded knob on
the tripod into the female thread on the bottom of the laser.

NOTE: Be sure that the tripod you are working with has a

5/8"–11 threaded screw to ensure secure mounting.

4. Turn the laser on and adjust the rotation speed and controls as
desired.
