OPERATION
WARNING:
Do not allow familiarity with tools to make you care- less. Remember that a careless fraction of a second is sufficient to inflict serious injury.
WARNING:
Always wear safety goggles or safety glasses with side shields when operating tools. Failure to do so could re- sult in objects being thrown into your eyes, resulting in possible serious injury.
APPLICATIONS
You may use this tool for the following purposes:
Charging compatible Ryobi 18 volt battery packs
CAUTION:
To prevent damage to the battery pack, remove the battery pack from the charger immediately if no LED comes on. Return the battery pack and charger to your nearest service center for checking or replacing. Also, if you are removing the battery pack from the charger and no LEDs are on, return both the battery pack and the charger to your nearest service center. Do not insert another battery pack into the charger. A damaged charger may damage a battery pack.
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 con- dition to prevent possible problems. Therefore, you should charge them 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
See Figure 2, page 8.
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.
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 indi- cates 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 a 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 a 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 cir- cumstances, return both the battery pack and charger to your nearest Authorized Service Center for electrical check.
