The charger and battery pack can be left connected with the green

LED glowing indefinitely. The charger will keep the battery pack

fresh and fully charged.
IMPORTANT CHARGING NOTES

1. Longest life and best performance can be obtained if the battery

pack is charged when the air temperature is between 60°F and 80°F

(16°- 27°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 60°F and 80°F

(16°- 27°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.

The standard charger provided will charge a fully depleted battery in

about 4 hours. 

1. Plug the charger into an appropriate outlet before inserting the

battery pack.

2. Insert the battery pack into the

charger as shown in figure A.

3. The green LED will flash

indicating that the battery is being

charged.

is indicated by the green LED

remaining on continuously. The pack

is fully charged and may be used at

this time or left on the charger.
