should let a hot battery pack cool down for approximately 30 minutes before attempting to 
recharge.
2. The charger and battery pack may become warm to touch while charging. This is a normal 
condition, and does not indicate a problem.

not cover the charger and do not charge battery packs in direct sunlight or near heat sources.

service center.

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 effect on the battery pack.

charging contacts inside the charger can be shorted by foreign material. Foreign materials of a 
conductive nature such as, but no limited to, steel wool, aluminum foil, or any buildup of metallic
