 After normal usage, a minimum of 1 hour of charging time
is required to fully recharge battery pack.
 The battery pack will become slightly warm to the
touch while charging. This is normal and does not
indicate a problem.
 Do not place the charger and battery pack in an area of
extreme heat or cold. They will work best at normal room
temperature.
NOTE: The charger and battery pack should be placed in
a location where the temperature is more than 50°F but
less than 100°F.
 When batteries become fully charged, unplug the
charger from power supply and remove the battery pack.
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
BATTERY PACK for normal recharging of batteries. If the
charger does not charge your battery pack under normal cir-
cumstances, return both the battery pack and charger to your
nearest Authorized Service Center for electrical check.
