indicated by the red light flashing at a fast rate (and continuous beeping
for 15 Minute Chargers). If this occurs, re-insert battery pack. If
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 for recycling. If the
new battery pack elicits the same trouble indication as the original,
have charger tested at an authorized service center.
PROBLEM POWER LINE
If your charger has 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.
HOT PACK DELAY
If your charger has a Hot 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.
15 MINUTE CHARGERS
1. Plug the charger into an appropriate power outlet. The charger will
beep twice, the red light will blink and go off.
2. Insert the battery pack into the charger, as shown in FIG. 1, making
sure the pack is fully seated in the charger. The red light will blink
and the charger will beep once indicating the charging process has
started.
3. The battery pack will be fully charged in less than 15 minutes under
most conditions. This will be indicated by the red light remaining ON
and 3 beeps. The pack is fully charged and may be used at this time
or left in the charger.
WEAK BATTERY PACKS: The charger 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
3:41 PM Page 4
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.
ALL CHARGERS
Leaving the battery pack in the charger: When the red light remains
ON, the charger has switched to its "equalize charge" mode which
lasts approximately 4 hours, after which the charger will switch to
"maintenance charge" mode. The battery pack can be removed at
any time during these charge cycles, but will only be fully charged if the
red light is continuously ON. 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. 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.
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.
3. If the battery pack does not charge properly — (1) Check current at
receptacle by plugging in a lamp or other appliance, (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 battery pack to a
location where the surrounding air temperature is approximately
65°F - 75°F (18°- 24°C). (4) If charging problems persist, take or
send 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
