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.
nCharge the battery pack only with the charger provided.
nMake sure the power supply is normal household voltage, 120 volts, 60 Hz, AC only.
nConnect the charger to the power supply.
nPlace the battery pack in the charger aligning raised rib on the battery pack with the groove in the charger.
nPress down on the battery pack to be sure contacts on the battery pack engage properly with contacts in the charger.
nNormally the red LED on charger will come on. This indicates the charger is in fast charging mode.
nRed 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.
nIf 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.

nAfter normal usage, a minimum of 1 hour of charging time is required to fully recharge battery pack.
nThe battery pack will become slightly warm to the touch while charging. This is normal and does not indicate a problem.
nDo 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.
nWhen 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 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 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 “CHARG- ING 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 Sears Repair Center for electrical check.
