OPERATING INSTRUCTIONS
Low Capacity Warning
If one LED on the POWER BAR begins to flash, the battery pack is
charged to less than 10% of its 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.
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, the POWER BAR will begin
to display four flashing LED lights. When this happens, remove the
tool from the workpiece and charge the battery pack as needed.
Battery Protection
The battery circuitry protects the battery pack from extreme
temperature, over-discharge, and over-charge. 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. This intelligent system will
shut down your battery pack if its operating temperature exceeds
176°F (80°C) and will begin normal operation when it returns to
32°F (0°C) - 122°F (50°C).
The POWER BAR will display four flashing LED lights if the circuitry
detects a momentary overload. Reset the battery pack by pressing
the POWER BAR button. Press the POWER BAR button again to
display the remaining charge.
NOTICE: A significantly reduced run time after fully charging the
battery pack indicates that the batteries are near the end of their
usable life and must be replaced.
