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
gives the same trouble indication as the original, have charger tested
at an authorized service center.
PROBLEM POWER LINE
When these chargers are used with some portable power sources
such as generators or sources that convert DC to AC, the chargers
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. Your power supply may need service.
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 slow-
ly lose its charge if left in a charger that is not plugged into an appro-
priate 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 tem-
perature 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 bat-
tery 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 suf-
ficient 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 material. 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: Don't allow any liquid to get inside charger. Electric
shock may result. 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.
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.
Important
This product is not user servicable. There are no user servicable parts
inside the charger. Servicing at an authorized service center is
required to avoid damage to static sensitive internal components.
READ ALL OF THE INSTRUCTIONS IN THE BATTERY CHARGER
SECTION OF THIS MANUAL BEFORE ATTEMPTING TO CHARGE
THE BATTERY PACK FOR YOUR TOOL.

ment pack exactly like it.) Never install any other battery pack. It will
ruin your tool and may create a hazardous condition.
