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 for tool or
battery
There are two types of overheating; tool overheating
and battery overheating. When the tool over heating
occurs, all speed indicators blink. When the battery over
heating occurs, indicator blinks.
If the overheating occurs, the tool stops automatically.
Let the tool and/or battery cool down before turning the
tool on again.
