the battery pack engage properly with contacts in the
charger.

correctly connected.

Do not place the charger in an area of extreme heat or
cold. It will work best at normal room temperature.

The battery pack may become slightly warm to the touch
while charging. This is normal and does not indicate a
problem.

latches and pull up on the battery pack.

the charger.
CHARGING A HOT BATTERY PACK
When using a tool continuously, the battery pack may be-
come hot. A hot battery pack may be placed directly onto
the charger port but charging will not begin until the battery
temperature cools to within acceptable temperature range.
When a hot battery pack is placed on the charger, the red
LED will begin flashing. When the battery pack cools, the
charger will automatically begin charging.
CHARGING A COLD BATTERY PACK
A cold battery pack may be placed directly onto the charger
port but charging will not begin until the battery temperature
warms to within acceptable temperature range. When a
cold battery pack is placed on the charger, the red LED will
begin flashing. When the battery pack warms, the charger
will automatically begin charging.
