Overloaded: 

The tool is operated in a manner that causes 
it to draw an abnormally high current. 
In this situation, release the switch trigger on 
the tool and stop the application that caused 
the tool to become overloaded. Then pull the 
switch trigger again to restart. 
If the tool does not start, the battery is 
overheated. In this situation, let the battery 
cool before pulling the switch trigger again. 

 

NOTE: 

The overheat protection works only with BL1415NA.
