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, if generator is powering electri- cal circuits, the chance of an elec- trical fire exists.

Note: We supply the engine owner’s manual with generator. Refer to that manual for questions concerning engine operation.

USING RECEPTACLE

Note: Do not exceed amperage rating of receptacles. Exceeding rating will trip re- ceptacle circuit breaker.

Use receptacles properly. Improper use could damage generator. Use only grounded exten- sion cords. Power only grounded or double- insulated items. Do not overload receptacles. All generators (except models HWI3000, MGH3000, and MGH3000PR) have the fol- lowing receptacles (see Figure 17):

•120V, 15-amp GFCI duplex receptacle

•120V, 30-amp twist-lock receptacle

•120/240V, 20 or 30-amp twist-lock receptacle

•120V, 15-amp duplex receptacle

Model MGH10000A also has a 120/240V, 50-amp receptacle (see Figure 17).

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

Models MGH3000 and MGH3000PR have only the 120V, 15-amp GFCI duplex receptacle.
