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 - 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. WARNING: Shock hazard. Do not allow any liquid to get inside charger. 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.
State of charge indicator (figure B)
The back of the battery is equipped with a state of charge indicator. This can 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
Checking state of charge during use: |
