IMPORTANT CHARGING SAFETY
INSTRUCTIONS

CHARGING THE POWER PACK

THE BATTERIES IN YOUR POWER PACK ARE NOT FULLY CHARGED AT THE
FACTORY. BEFORE ATTEMPTING TO CHARGE THEM, THOROUGHLY READ ALL
OF THE SAFETY INSTRUCTIONS.
The charger is designed to use standard household 120 volt 60 Hz power.
1. Plug the charger into any standard 120 Volt 60 Hz electrical outlet. NOTE: Do not
charge by means of an engine generator or DC power source. Use only 120V
AC.
2. Slide the charger onto the power pack as shown in figure 7 & 8 and let the power
pack charge initially for 9 hours. After the initial charge, under normal usage, your
power pack should be fully charged in 6 to 9 hours.
3. Unplug charger, and remove the power pack. Place the power pack in the unit
and be certain that it is inserted fully into the battery cavity until it "clicks"
into place.
NOTE: To remove the power pack from the unit, press down on the release button
on the back of the pack (Figure 9) and slide out.

IMPORTANT CHARGING NOTES

1. After normal usage, your power pack should be fully charged in 6 to 9 hours. If the
power pack is run-down completely, it may take up to 9 hours to become fully
charged. Your power pack was sent from the factory in an uncharged condition.
Before attempting to use it, it must be charged for at least 9 hours.
2. DO NOT charge the power 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
power pack. Longest life and best performance can be obtained if power pack is
charged when air temperature is about 75°F (24°C).
3. While charging, the charger may hum and become warm to touch. This is a normal
condition and does not indicate a problem.
4. If the power pack does not charge properly—(1) Check current at receptacle by
plugging in a lamp or other unit. (2) Check to see if receptacle is connected to a
light switch which turns power off when you turn out the lights. (3) Move charger
and power pack to a surrounding air temperature of 40°F (+4.5°C) to 105°F
(+40.5°C). (4) If the receptacle and temperature are OK, and you do not get proper
charging, take or send the power pack and charger to your local Black & Decker
service center. See Tools Electric in yellow pages.
5. The power pack should be recharged when it fails to produce sufficient power on
jobs which were easily done previously. DO NOT CONTINUE using unit with its
power pack in a depleted condition.
6. The power pack will reach optimum performance after being cycled 5 times during
normal usage. There is no need to run the batteries down completely before
recharging. Normal usage is the best method of discharging and recharging the
power pack.
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.
