LED FUNCTIONS
OF CHARGER
LED WILL BE ON TO INDICATE
STATUS
OF
CHARGER
AND BATTERY
PACK:
[] Red LED on = Fast charging mode.
[] Green LED on = Fully charged and in maintenance
charge mode.
[] Green LED on = When battery pack is inserted into
charger, indicates hot battery pack or that battery pack
is out of normal temperature
range.
[] Yellow and Green LEDs on = Deeply discharged or
defective battery pack.
[] No LED on = Defective charger or battery pack.
CHARGING
THE BATTERY
PACK
Battery packs for this tool are 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 below normal temperature
range, the
green LED on charger will come on. Allow battery pack to
reach normal temperature, then the red LED will come on.
NOTE: If the charger does not charge the battery pack under
normal circumstances, return both the battery pack and char-
ger to your nearest Sears or other qualified 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, AO 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.
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 product continuously, the batteries in the
battery pack will become hot. You should let a hot bat-
tery 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 Sears or
other qualified 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.
