Do not touch the coolant sub-tank. 

 

 

This generator is equipped with functions to automatically stop operation when there is a 

fault/malfunction during operation, and one to warn the operator of the fault location by use of 

indicator lamps. Check the fault location when the engine is automatically stopped or an
