HIGH ALTITUDE OPERATION

This generator will not perform well at high altitudes without proper adjustment. See engine owner’s manual for details.

ADDING ELECTRICAL

LOADS

IMPORTANT: Do not overload generator. Make sure total wattage of all electrical loads does not exceed rated wattage of generator. Overloading may shorten generator life. It could also cause internal damage to genera- tor. Overloading will trip circuit breaker.

IMPORTANT: (All models except HWI3000, MGH3000, MGH3000PR, MGH7000D, MGH7000DI, and MGH10000A) Keep full power selector switch in the 120 VOLT ONLY position if only powering 120V items. Only move switch to 120/240 VOLT position if powering 240V items.

1.Check items to be powered. Their nameplate lists their wattage ratings.

Note: The wattage ratings for some elec- trical motors are misleading. They may require up to three-times their rated watt- age to start. You must figure total electri- cal load wattage. Make sure total wattage of all electrical loads does not exceed rated wattage of generator. See Determining Electrical Load For Generator, page 10.

2.Start engine. Let engine reach full speed.

3.Connect electrical loads one at a time. If the load consists of electric motors, start them first. Always start the larg- est first. Start each motor individually.

DISCONNECTING ELECTRIC LOADS

Remove electrical loads one at a time. Re- move voltage sensitive items first. Voltage sensitive items include TVs, VCRs, and other home electronic items.

STOPPING ENGINE

IMPORTANT: The engine speed is preset. The throttle is locked in preset position. Do not adjust throttle.

Follow the steps below to stop engine.

1.Remove all electrical loads from gen- erator (see Disconnecting Electrical Loads). Remove electrical loads one at a time.

2.Let engine run for two or three min- utes after removing electrical loads. This lets engine cool slightly.

3.Turn engine switch to the OFF posi- tion (see Figure 29).

4.Turn fuel valve lever off except on Model MGH3000PR. Do this by mov- ing valve lever fully to the left (see Fig- ure 30).
