APPLICATIONS
You may use this tool for the following purpose:

Charging Ryobi 40 Volt lithium-ion batteries
CAUTION:
If at any point during the charging process none of the
LEDs are lit, remove the battery pack from the charger
to avoid damaging the product. DO NOT insert another
battery. Return the charger and battery to your nearest
service center for service or replacement.
CAUTION:
Charge in a well ventilated area. Do not block charger
vents. Keep them clear to allow proper ventilation.
CHARGING
See Figure 2, page 8.
Battery packs are shipped in a low charge condition to
prevent possible problems. Therefore, you should charge
them before first use.
If the charger does not charge your battery pack under
normal circumstances, return both the battery pack and
charger to your nearest repair center for electrical check.
 Install power cord onto charger fully by inserting the cord
end into cord socket and pressing firmly.
 Make sure the power supply is normal household voltage,
120 volts, AC only, 60 Hz.
 Connect the charger to a power supply.
 Attach the battery pack to the charger by aligning the
raised ribs on the battery pack with the grooves in the
charger, then slide the battery pack onto the charger.
 Press down on the battery pack to be sure contacts on
the battery pack engage properly with contacts in the
charger.
 Latches should snap into place to ensure charger is
correctly connected.
 Do not place the charger in an area of extreme heat or
cold. It 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 90°F.
 The battery pack will become slightly warm to the
touch while charging. This is normal and does not
indicate a problem.
 After charging is complete, the green LED will remain on.
 To remove the battery pack from the charger, depress
latches and pull up on the battery pack.
CHARGING A HOT BATTERY PACK
When using a tool continuously, the battery pack may
become hot. A hot battery pack may be placed directly
onto the charger port but charging will not begin until the
battery temperature cools to within acceptable temperature
range. When a hot battery pack is placed on the charger,
the red LED will begin flashing and the green LED will be
off. When the battery pack cools to approximately 120°F
(40°C), the charger will automatically begin charging.
