tery is placed under one of the following conditions:
Overload protection
When the machine or battery is operated in a manner
that causes it to draw an abnormally high current, the
machine automatically stops and the speed indicator
blinks in green. In this situation, turn the machine off
and stop the application that caused the machine to
become overloaded. Then turn the machine on to
restart.
