OPERATION 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 The battery pack for this inflator has 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 3.  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. GREEN LED YELLOW LED RED LED BATTERY PACK SHOWN IN CHARGER Fig. 2 CHARGER BATTERY PACK Fig. 3 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 inflator 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 inflator 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. 10
