OPERATING INSTRUCTIONS
Low Capacity Warning
If one LED of the power indicator (C) begins to flash, the battery
pack is charged to less than 20% 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. It is not necessary to completely
discharge the battery pack before recharging. Remove the battery
pack from the tool and recharge it when it is convenient or when it
is not in use.
Battery Protection
The battery circuitry protects the battery pack from extreme
temperature, over-discharge, and over-charge. To protect the battery
pack 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 system will begin normal
operation when it returns to 32°F (0°C) - 122°F (50°C).
The power indicator (C) will display four flashing LED lights if the
circuitry detects a momentary overload. Reset the battery pack by
pressing the power-indicator button (A). Press the power indicator
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.
