GROUNDING

WARNING:You must properly earth-ground generator before starting. This will help guard againstdeadlyelectricshock.Only use grounded plugs with genera- tor. Only use grounded extension cords. Only use three-wire or double-insulated power tools.

Grounding generator helps prevent electric shock from a ground fault condition. Locate ground lug on roll cage (see Figure 12). Attach a #10 stranded-copper ground wire to ground lug. Drive grounding point into ground. Grounding point can be a stake, grounding rod, or pipe. Grounding point should be copper or brass. Attach ground wire to grounding point. You must supply the ground wire and grounding point. These do not come with generator. Follow the National Electrical Code and all state and local codes. Consult your power company or a licensed electrician.

WARNING: For a grounding point, do not use metal pipe be- ing used to carry combustible materials or gases.

STANDBY INSTALLATION TO HOME OR BUILDING

WARNING: Have standby in- stallation performed by a skilled, licensed electrician. Do not let anyone else wire into a utility circuit. Personal injury, equip- ment damage,or damage to home could occur.

IMPORTANT: This generator will not power your entire home. Most home utility electric service is more than 60 amps. This will exceed generator output. Only power needed items during a power outage. Make sure total wattage of electrical load does not exceed rated wattage of generator.

You may need to use this generator as a standby power source. During a power out- age, the generator will power selected items in a building. Have generator and additional wiring installed by a skilled, licensed electri- cian. This is not a do-it-yourself job. Follow all local codes.

WARNING: The electrician must install a double-throw transfer switch. This isolates ex- isting electrical circuits from the utility power line. If not isolated,
