be used to display the current level of charge in the battery during use and 

during charging. It does not indicate tool functionality and is subject to variation 

based on product components, temperature and end-user application.

  • Press the state of charge indicator button (B1).

  • The four LED’s (B2) will illuminate indicating the percent of charge in the

  • If LED light does not lluminate, charge battery.

This battery is designed to not

fresh and fully charged. 

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 - 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.

Shock hazard. Do not allow any liquid to get 

inside charger. Never attempt to open the battery pack for any
