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 another
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).
