OPERATION

GENERAL INFORMATION

This generator is not large enough to power your entire home. Do not connect generator to any existing electrical circuits. Plug items directly into generator receptacles. Do not exceed amperage rating of receptacles. Only use grounded cords.

DANGER: Use only in well- vented areas. Make sure area has plenty of free-moving, fresh, out- side air. Never run generator in an enclosed or confined area. Never run generator inside occu- pied building. Engine exhaust contains poisonous carbon mon- oxide gas. Overexposure will cause loss of consciousness and will lead to death.

DANGER: Never connect gen- erator to any existing electrical circuits. The generator output will back-feed into the utility power line. This may electrocute a power company line repair person. Also,

Model MGH10000A also has a 120/240V, 50-amp receptacle (see Figure 15).

Model HWI3000 has only the 120V, 20- amp duplex receptacle.

Model MGH3000 has only the 120V, 15- amp GFCI duplex receptacle.
