APPLICATIONS
You may use this product for the following purpose:
 Charging RYOBI 40 Volt Lithium-ion batteries
NOTICE:
Charge in a well-ventilated area. Do not block charger
vents. Keep them clear to allow proper ventilation.
CHARGING
See Figures 1 - 2, page 7.
Battery packs are shipped in a low charge condition.
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.
Charge time varies and is dependent upon the amp hour
capacity of battery pack.
 Turn the battery pack upside down so that the latch faces
up.
 Attach the charger to the battery pack by aligning the
raised ribs on the battery pack with the grooves in the
charger, then slide the charger onto the battery pack.
NOTE: The connection between the battery pack and
charger may feel slightly loose. This is normal and does
not indicate a problem.
 Press down on the charger to be sure contacts on
the battery pack engage properly with contacts in the
charger.

OPERATION

 The latch should snap into place to ensure charger is
correctly connected.
 Connect the power adaptor to a power source, then
connect the power cable to the charger.
NOTE: Make sure the power supply is normal household
voltage, 120 volts, AC only, 60 Hz.
 Do not place the charger in an area of extreme heat or
cold. It will work best at normal room temperature.
 The battery pack will become slightly warm to the touch
while charging. This is normal and does not indicate a
problem.
 The LED will slowly flash green while the battery pack is
charging.
NOTE: If the LED flashes green and red, the charger
has detected a fault. See LED Functions for Battery
Charging for details.
 After charging is complete, the charger LED will stop
flashing and remain green for approximately 5 minutes.
All battery pack LEDs will turn off to indicate that the
battery pack is 100% charged.
 To remove the battery pack from the charger, depress
the latch and slide the charger off the battery pack.
 Remove the power adaptor from the power source. Store
charger in a dry location.
CHARGING A HOT BATTERY PACK
When using a tool continuously, the battery pack may
become hot. The charger may be placed directly onto a hot
battery pack but charging will not begin until the battery
temperature cools to within an acceptable temperature
range. When the charger is placed on a hot battery pack
the LED will turn orange and remain on. When the battery
pack cools, the charger will automatically begin charging.
CHARGING A COLD BATTERY PACK
The charger may be placed directly onto a cold battery pack
but charging will not begin until the battery temperature
warms to within an acceptable temperature range. When
the charger is placed on a cold battery pack the LED will
turn orange and remain on. When the battery pack warms
the charger will automatically begin charging.
