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. Whenever 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
transition to a maintenance charge; the indicator light shuts off
when the automatic Tune-Up™ Mode is complete.

Charging Procedure
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.
CAUTION: 120 volts present at charging terminals. Do not probe
with conductive objects. Danger of electric shock or electrocution.
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.
