IMPORTANT: Make sure battery connec- tions are the correct polarity. Electric start generators use negative ground, 12-volt DC starting system.

A battery is not supplied with generator. You must provide a 12-volt, 32-amp-hour battery. The positive and negative battery cables are supplied with generator. You must install these cables before mounting battery.

Always wear safety glasses when working with battery. Make sure battery terminals are clean. Make sure cable connections are tight.

Always shut down engine before removing
