with the battery packs or the power source. Problems are indicated
by one LED flashing in different patterns.

this happens, the charger automatically switches to the Pack
Charging mode. This feature ensures maximum battery life. The
light flashes in the pattern indicated on the label.
Problem power line
When the charger is used with some portable power sources
such as generators or sources that convert DC to AC, the
charger may temporarily suspend operation. The LED
flashes in the pattern indicated on the label. This indicates
that the power source is out of limits.
Leaving the battery in the charger
The charger and battery pack can be left connected with the LED
glowing indefinitely. The charger will keep the battery pack fresh and
fully charged. This charger features an automatic tune-up mode
which equals or balances the individual cells in the battery pack to
allow it to function at peak capacity.
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).
