manual abstract
Tilting could cause battery acid to spill. Wear protective clothing and face shield when servicing. Keep out of children’s reach. • If battery acid gets on your skin, wash with water. • If battery acid gets in your eyes, flush with water at least 15 minutes. Call a doctor at once. Battery acid is poisonous. • If swallowed, drink large amounts of water or milk. Follow with milk of magnesia or vegetable oil. Call a doctor at once. 12 Continued BATTERY (Model MGH7000 Only) Continued CAUTION If you remove battery, insulate the red, positive (+) battery cable terminal. Insulate with electrical tape. Exposed terminal may spark when generator runs. IMPORTANT:Make sure battery connections are the correct polarity. Electric start generators use negative ground, 12-volt DC starting system. Model MGH7000 has an electric starter. 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 or attaching battery cables. Always remove the negative (–) cable first. Always attach negative (–) cable last. INSTALLING BATTERY CABLES TO ENGINE 1. Attach the red, positive (+) battery cable to the starter solenoid on engine (see Figure 8). 2. Attach the black, negative (–) battery cable to the engine block. Use the bolt, nut, and two washers provided with the battery cables. Use long mounting hole on opposite side of engine from starter solenoid. Attach cable as shown in Figure 9.

Secure battery to generator by battery hold-down system. This system consists of the battery mounting bracket, hook bolts, and nut (see Figure 10). 2. Locate the red, positive (+) battery cable from starter solenoid. Connect it to the positive (+) battery terminal (see Figure 11). 3. Locate the black, negative (–) battery cable attached to engine block. Connect it to the negative (–) battery terminal (see Figure 11). 4. Check battery before starting engine. Make sure fluid levels are full. Make sure battery is charged. See engine owner’s manual for more information.

This will help guard against deadly electric shock. Only use grounded plugs with generator. 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 end of generator housing (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. They 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 being used to carry combustible materials or gases.

Do not let anyone else wire into a utility circuit. Personal injury, equipment 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 can use this generator as a standby power source. During a power outage, the generator will power selected items in a building. Have generator and additional wiring installed by a skilled, licensed electrician. This is not a do-it-yourself job. Follow all local codes. WARNING The electrician must install a double-throw transfer switch. This isolates existing electrical circuits from the utility power line. If not isolated, generator output will back-feed into ut...
