LOW-CAPACITY WARNING
If one LED on the power indicator begins to
flash, the battery pack charge is under 10%
capacity and should be recharged. Unlike other
types of battery packs, lithium-ion battery packs
deliver fade-free power for their entire run time.
The tool will not experience a slow, gradual loss
of power as it is used.
OVER-TEMPERATURE WARNING
The battery circuitry also protects the battery
pack from overheating. To protect the battery
pack from damage and prolong its life, the
battery pack circuitry will send a warning signal
to the tool if the temperature becomes too high
during use. The first and third LEDs on the
power indicator will rapidly flash green to warn
of the over-temperature condition.
OVERLOAD (MODEL FX0311 ONLY)
If overload occurs, the first and fourth LEDs of
the power indicator will flash simultaneously.
COLD WEATHER OPERATION
When the battery pack is very cold, the
performance may be weakened. Put the
battery pack on a tool and use the tool in a
TO CHARGE THE BATTERY PACK (FIG. 2)
NOTE : This lithium-ion battery pack is shipped
partially charged. Before using it for the first
time, fully charge the battery pack.
Always charge the battery pack with the correct
charger.
Please refer to the charger manual for detailed
charging instructions.
a. Connect the charger to a power supply.
b. Attach the battery pack to the charger by
aligning the raised ribs of the battery pack
with the slot in the charger. Slide the battery
pack onto the charger.
c. When the charger indicates that the battery
pack is fully charged, remove it from the
charger.
NOTE : If the battery pack cannot accept a
charge, the contacts of the charger or battery
pack may be contaminated. Clean the contacts
The power delivered to the tool will drop quickly
when the battery pack is at the end of its run
time and needs to be charged. When the
battery pack is completely discharged or over-
voltage, the power indicator will begin to flash
all four LEDs. When this happens, remove the
tool from the workpiece and charge the battery
pack as needed.
This may happen in extremely high torque,
binding, and stalling situations. The battery pack
will begin normal operation after it has cooled
down.
A significantly reduced run time
NOTICE
after fully charging the battery
pack indicates that the batteries are near the
end of their usable life and must be replaced.
Remove the battery pack from the power tool
and reinsert it after 10 seconds. When operate
the power tool, it is recommended to reduce the
load.

temperature until it has warmed. The battery
pack will operate normally.

and removing the battery several times or
scrubbing with a cotton swab and alcohol), or
