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 orAmerican
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. If an extension cord is to be used outdoors it must be marked with the suffix
W-A or W following the cord type designation. For example - SJTW-A to indicate it is
acceptable for outdoor use.

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 immedi-
ately.
•
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, electrocu-
tion 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 (120
Volts). Do not attempt
to use it on any other
voltage.
This does not apply to the
vehicular charger.

Charging
Procedure
DG4400B, DG6300B AND DGT000B
A DANGER: Electrocution hazard. 120 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. Remove the caps from the battery pack and insert 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.
Using
Automatic
Tune-Up
TM
Mode
DG4400B, DG6300B AND DGT000B
The automaticTune-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.

Indicators
DG4400B, DG6300B AND DG7000B
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. Such batteries are
still usable but should not be expected to perform as much work. In such cases, about 10
seconds after battery insertion, the charger will beep rapidly 8 times to indicate a weak
battery condition. The charger will then go on to charge the battery to the highest capacity
possible.
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 nor-
mal 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.
