3 "side to side" lights – battery charge is
too low to run tool.Recharge the battery.
1 red light – battery is too hot for use.
Turn tool off and let the battery
cooldown.
Your tool is equipped with advanced
electronics that protect the Li-Ion cells in
the battery from damage due to excessi-
ve operating temperature and/or current
draw. If the warning symbol illuminates
red and/or the tool stops working during
heavy use, this most likely indicates that
the Li-Ion cells are near their maximum
operating temperature, and the battery
pack should either be changed or
allowed to cool to ambient temperature
before continuing use. If the tool auto-
matically turns off due to overload condi-
tions, the switch must be turned off for a
few seconds to allow the circuit to reset
before continuing use.
