its run time and needs to be charged, power to the tool will drop quickly.
The power indicator will begin to display four flashing LED lights when it
is completely discharged. When this happens, remove the tool from the
workpiece and charge the battery pack as needed.
BATTERY PROTECTION
To protect the battery from damage and prolong its life, the battery pack
circuitry will turn off the battery pack if it becomes overloaded or if the
temperature becomes too high during use. This may happen in extremely
high torque, binding and stalling situations. The battery pack will begin
normal operation when it cools down.
The power indicator will display four flashing LED lights if the circuitry
detects a momentary overload. You can conveniently reset the battery pack
by releasing the power-tool trigger. Press the power indicator button again to
display the remaining charge.
NOTE: If the power indicator continues to flash four LED lights after resetting,
place the battery pack on the charger to evaluate the battery condition.
NOTE: A significantly reduced run time after fully charging the battery pack
indicates that the battery is near the end of its usable life and must be replaced.
COLD WEATHER OPERATION
When the battery pack is very cold, it may “pulse” for the first minute of
use to warm itself. Put the battery pack on a tool and use the tool in a light
application. After about a minute, the battery pack will have warmed itself
and will operate normally.
WHEN TO CHARGE THE BATTERY PACK
The Lithium-Ion battery can be charged at any time and will not develop a
“memory” when charged after only a partial discharge. It is not necessary
to run down the battery pack charge before recharging. Remove the battery
pack from the tool when convenient for you and your job.
Use the power indicator to determine when you need to recharge the
battery pack.
You can “top-off” your battery pack’s charge before starting a big job or
long period of use.
Due to Lithium-Ion’s fade-free properties, the only time it is necessary to
charge the Lithium-Ion battery pack is when the pack has reached the
end of its charge. To signal the end of charge, power to the tool will drop
quickly. Charge the battery pack as needed.
