A common practice is to use a solution of one pound (500 grams) bicarbon- ate of soda to one gallon (4 liters) of water . The bicarbonate of soda solution is to be added until the evidence of reaction (foaming) has ceased.
Generac ® Pow er Systems, Inc. 13 Make sure the generator battery is fully charged, prop- erly installed and interconnected, and ready for use. Check to ensure that there are no loose electrical con- nections. Restrain any loose wires to keep them clear of any moving generator set components.
14 Generac ® Pow er Systems, Inc. 3.2.3 1 5 AMP F USE F use protects the control console’s DC control circuit against electrical overload. If the fuse has melted open because of an overload, engine cranking and startup cannot occur . If the fuse needs to be replaced, use only an identical 15-amp replacement fuse.
