WARNING
: This generator produces powerful voltage, which can
result in electrocution.
• ALWAYS ground the generator before using it (see the “Ground the Generator”
portion of the “GENERATOR PREPARATION” section).
• Generator should only be plugged into electrical devices, either directly or with an
extension cord. NEVER connect to a building electrical system without a qualified 
electrician. Such connections must comply with local electrical laws and codes. 
Failure to comply can create a back-feed, which may result in serious injury or death 
to utility workers. 
• Use a ground fault circuit interrupter (GFCI) in highly conductive areas such as
metal decking or steel work. GFCIs are available in-line with some extension cords.
• Do not use in rainy conditions. 
• Do not touch bare wires or receptacles (outlets). 
• Do not allow children or non-qualified persons to operate.
WARNING
: This generator produces heat when running. Temperatures
near exhaust can exceed 150º F (65º C).
• Do not touch hot surfaces. Pay attention to warning labels on the generator identifying
hot parts of the machine.
• Allow generator to cool down after use before touching engine or areas of the generator
that become hot during use.
 
 
CAUTION: Misuse of this generator can damage it or shorten its life. 
• Use generator only for its intended purposes. 
• Operate only on dry, level surfaces. 
• Allow generator to run for several minutes before connecting electrical devices.
• Shut off and disconnect any malfunctioning devices from generator. 
• Do not exceed the wattage capacity of the generator by plugging in more electrical devices 
than the unit can handle.
• Do not turn on electrical devices until after they are connected to the generator.
• Turn off all connected electrical devices before stopping the generator. 
• Turn engine switch to “off” position when the engine is not running.
