Charge Indicators
Some chargers are designed to detect certain prob-
lems that can arise with battery packs. Problems
are indicated by the red light flashing at a fast rate.
If this occurs, re-insert battery pack into the charger.
If the 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 or other
collection site for recycling. If the new battery pack
elicits the same trouble indication as the original,
have the charger tested at an authorized service
center.
HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay fea-
ture: 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 bat-
tery 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.
PROBLEM POWER LINE
Some chargers have 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.
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.
WEAK BATTERY PACKS: Chargers can also detect
a weak battery pack. Such batteries are still usable
but should not be expected to perform as much work.
The charger will indicate to replace battery pack.

CHARGER SAFETY
Important Charging Notes
1. Longest life and best performance can be obtained
if the battery pack is charged when the air tempera-
ture 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:
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. Under certain conditions, with the charger plugged
into the power supply, the exposed charging contacts
inside the charger can be shorted by foreign mate-
rial. 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
charger before attempting to clean.
6. Do not freeze or immerse charger in water or any
other liquid.
uid to get inside charger. Electric shock may result.
pack for any reason. If the plastic housing of the bat-
tery pack breaks or cracks, return to a service center
for recycling.
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 loca-
tion where the surrounding air tempera-
ture 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.
WARNING: Shock hazard. Don't allow any liq-
CAUTION: Never attempt to open the battery
