three red lights will flash together with two fast blinks followed by a pause. This
indicates that the power souce is out of limits.
BAD BATTERY
The charger can detect a weak or damaged battery. The three red lights will flash
together with rapid blinking. The battery will no longer charge and should be returned
to a service center or a collection site for recycling.
BAD CHARGER
The charger will detect if it is not functioning properly. The three red lights will flash
together with one fast blink followed by a long blink. The charger will no longer work
and should be returned to an authorized service center or replaced.
LEAVING THE BATTERY IN THE CHARGER
The charger and battery pack can be left connected with the red lights glowing
indefinitely. The charger will keep the battery pack fresh and fully charged. This
charger features an automatic tune-up mode which equals or balances the individual
cells in the battery pack to allow it to function at peak capacity. Battery packs should
be tuned up weekly or whenever the battery no longer delivers the same amount of
work. To use the automatic tune-up mode, place the battery pack in the charger and
leave it for at least 8 hours.

Important Charging Notes

1. Longest life and best performance can be obtained if the battery pack is charged
when the air temperature is between 18°- 24°C (65°F and 75°F). DO NOT charge
the battery pack in an air temperature below +4.5°C (+40°F), or above +40.5°C
(+105°F). 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 uninsu-
lated 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 tem-
perature is approximately 18°- 24°C (65°F - 75°F).
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 the charging procedure. You may also charge a partially used
pack whenever you desire with no adverse affect on the battery pack.
5. 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.
6. Do not freeze or immerse charger in water or any other liquid.
WARNING: Shock hazard. Do not allow any liquid to get inside charger.
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.
