Charger Diagnostics
This charger is designed to detect certain problems that can
arise with the battery packs or the power source. Problems
are indicated by one LED flashing in different patterns.
Bad Battery
The charger can detect a weak or damaged battery. The LED
flashes in the pattern indicated on the label. If you see this
bad battery blink pattern, do not continue to charge the
battery. Return it to a service center or a collection site for
recycling.
Hot/Cold Pack Delay
When the charger detects a battery that is excessively
hot or excessively cold, it automatically starts a Hot/Cold
Pack Delay, suspending charging until the battery has
normalized. After this happens, the charger automatically
switches to the Pack Charging mode. This feature ensures
maximum battery life. The light flashes in the pattern
indicated on the label.
Leaving the Battery in the Charger
The charger and battery pack can be left connected with
the LED 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. 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.
Charger Cleaning Instructions
WARNING:
Shock hazard. Disconnect
the charger from the AC outlet before cleaning. Dirt
and grease may be removed from the exterior of the
charger using a cloth or soft non-metallic brush. Do
not use water or any cleaning solutions.
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 +104 °F (+40 °C). This is important
and will prevent serious damage to the battery pack.
2. The charger and battery pack may become warm to the
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 operation of 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 the 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 effect on the battery pack.
5. Foreign materials of a conductive nature such as, but
not limited to, grinding dust, metal chips, 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 the charger
before attempting to clean.
6. Do not freeze or immerse the charger in water or any
other liquid.
Storage Recommendations
1. The best storage place is one that is cool and dry, away
from direct sunlight and excess heat or cold.
