CHARGING THE BATTERy PACK
Battery packs for this product have been shipped in a low
charge condition to prevent possible problems. Therefore,
you should charge it until the green LED on the front of the
charger comes on.
NOTE: Batteries will not reach full charge the first time they
are charged. Allow several cycles (operation followed by
recharging) for them to become fully charged.
CHARGING A COOL BATTERy PACK
If battery pack is within normal temperature range, the red
LED on charger will come on.
NOTE: If the charger does not charge the battery pack
under normal circumstances, return both the battery pack
and charger to your nearest Authorized Service Center for
electrical check.

Charge the battery pack only with the charger provided.
 Make sure the power supply is normal household
voltage, 120 volts, 60 Hz, AC only.
 Connect the charger to the power supply.
 Place the battery pack in the charger aligning raised rib
on the battery pack with the groove in the charger. See
Figure 2.
 Press down on the battery pack to be sure contacts on
the battery pack engage properly with contacts in the
charger.
 Normally the red LED on charger will come on. This
indicates the charger is in fast charging mode.
 Red LED should remain on for approximately 1 hour
then the green LED will come on. Green LED on
indicates battery pack is fully charged and charger is
in maintenance charge mode.
NOTE: The green LED will remain on until the
battery pack is removed from the charger or charger is
disconnected from the power supply.
 If both yellow and green LEDs come on, this indicates
a deeply discharged or defective battery pack.
Allow the battery pack to remain in the charger for 15
to 30 minutes. When the battery pack reaches normal
voltage range, the red LED should come on. If the
red LED does not come on after 30 minutes, this may
indicate a defective battery pack that should be
replaced.
 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.
OPERATION
 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 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.
