NOTE: DO NOT use a garden hose to clean generator.  
Water can enter engine fuel system and cause problems. In  
addition, if water enters generator through cooling air slots,  
some of the water will be retained in voids and cracks of  
the rotor and stator winding insulation.Water and dirt  
buildup on the generator internal windings will eventually  
decrease the insulation resistance of these windings.
