CHARGING A HOT BATTERY PACK
When using the tool continuously, the batteries in the battery
pack will become hot. You should let a hot battery pack cool
down for approximately 30 minutes before attempting to
recharge. When the battery pack becomes discharged and
is hot, this will cause the green LED to come on instead of
the red LED. After 30 minutes, reinsert the battery pack in
the charger. If the green LED continues to remain on, return
battery pack to your nearest Authorized Service Center for
checking or replacing.
NOTE: This situation only occurs when continuous use of the
tool causes the batteries to become hot. It does not occur
under normal circumstances. Refer to CHARGING A COOL
BATTERY PACK for normal recharging of batteries. If the
charger does not charge your battery pack under normal
circumstances, return both the battery pack and charger
to your nearest Authorized Service Center for electrical
check.

CAUTION:
