damaged in any way (i.e., pierced with a nail, hit with a hammer, stepped on). Damaged
battery packs should be returned to service center for recycling.
CAUTION: When not in use, place tool on its side on a stable surface where it will not
cause a tripping or falling hazard. Some tools with large battery packs will stand upright on
the battery pack but may be easily knocked over.
WARNING: Fire hazard. Do not store or carry battery so that metal objects can contact
exposed battery terminals. For example, do not place battery in aprons, pockets, tool boxes,
product kit boxes, drawers, etc., with loose nails, screws, keys, etc. Transporting batteries
can possibly cause fires if the battery terminals inadvertently come in contact with
conductive materials such as keys, coins, hand tools and the like. The US Department of
Transportation Hazardous Material Regulations (HMR) actually prohibit transporting batteries in
commerce or on airplanes (i.e., packed in suitcases and carry-on luggage) UNLESS they are
properly protected from short circuits. So when transporting individual batteries, make sure that
the battery terminals are protected and well insulated from materials that could contact them
and cause a short circuit.

Storage Recommendations
1. The best storage place is one that is cool and dry away from direct sunlight and excess heat
or cold.
2. Long storage will not harm the battery pack or charger. Under proper conditions, they can be
stored for 5 years or more.
Charger
Your battery pack requires a 1 hour D
before using your charger. Consult the chart on the back of this manual for compatibility of
chargers and battery packs.

Charging Procedure

1. Plug the charger into an appropriate outlet before inserting the battery pack.
2. Insert the battery pack into the charger. The charger is equipped with a three-light fuel gauge
that will blink according to the state of charge of the battery pack.
3. The completion of charge is indicated by the three red lights remaining ON continuously. The
pack is fully charged and may be used at this time or left on the charger.

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 ser-
vice 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.
