draw an abnormally high current, the tool stops automatically. In
this situation, turn the tool off and stop the application that caused
the tool to become overloaded. Then turn the tool on to restart.

Overheat protection

When the tool/battery is overheated, the tool stops automatically. In
this situation, let the tool/battery cool before turning the tool on again.
