OPERATION
CHARGING A COOL BATTERY PACK
See Figure 2.
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 charger to your nearest Sears Repair Center for
electrical check.
Charge the battery pack only with the charger provided.
Make sure the power supply is normal household
voltage,
120 V, 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.
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 and 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 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 Sears
Repair 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 the battery pack under
normal circumstances, return both the battery pack and
charger to your nearest Sears Repair Center for electrical
check.
