Charger Diagnostics
This charger is designed to detect certain problems that can arise
with the battery packs or the charger. Problems are indicated by the
three red lights flashing together in different patterns.
PROBLEM POWERLINE
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. The 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 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. 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.
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 temperature is approximately 65°F - 75°F
(18°- 24°C).
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.
