FEATURES

OIL ALERT SYSTEM

The oil alert system protects the engine from low oil damage. This system automatically shuts down the engine and prevents engine restarting if the oil level falls too low.

Note: When this happens, the engine switch remains in the ON position. The oil alert system is wired into the ON/OFF Switch.

If this system shuts down the engine, the engine will not start until you add oil. Add oil to engine (see Engine Oil, page 7).

Note: Operate generator on a level surface. If not level, the oil may flow away from the oil level sensing device. This will cause the oil alert system to shut down engine.

See engine owner’s manual for more information.

FULL POWER SELECTOR SWITCH

All models except HWI3000, MGH3000G, MGH3000, MGH3000PR, MGH6500IE, and MGH10000A have a full power selector switch on the control panel. The switch has two positions: 120 VOLT ONLY, and 120/ 240 VOLT.

120 VOLT ONLY: This position sends full power to the 120V receptacles only. 240V power is not available. Use this position when powering 120V items only.

120/240VOLT:Thispositionsendsfullpower to the 120/240V receptacle. It also powers the 120V receptacles at reduced wattage capacity.

IMPORTANT: Do not move the full power selector switch while powering electrical items. Unplug all items before moving switch. Failure to do so can damage switch. Models HWI3000, MGH3000G, MGH3000, MGH3000PR, MGH6500IE, and MGH10000A do not have this switch. These models provide full power to all receptacles.

AUTO-IDLE SYSTEM

The Auto-Idle System allows the engine to idle down or run at a slower speed when the generator is not being used to supply power. The Auto-idle system can be turned ON or OFF by a rocker switch on the control panel. When the switch is in the OFF position, the engine runs at full speed all of the time. When the switch is in the ON position, the engine slows down to idle speed until an electrical load is applied. When a load is applied to the generator (an electrical item is plugged in and turned on) the engine speeds up to the preset speed required to produce the correct voltage.

IMPORTANT: A minimum current load of 1 Amp is required to disengage the auto idle solenoid and cause the engine to come up to speed for correct voltage. Powering items at reduced engine speed will damage genera- tor and powered items.

ELECTRIC START

(Models MGH5000DIE, MGH6500IE, and MGH10000A)

Models MGH5000DIE, MGH6500IE, and MGH10000A have electric starters. A bat- tery is not supplied with generator. You must provide a 12-volt, 32-amp-hour bat- tery. For more battery information, see Bat- tery, page 8.

GROUND FAULT CIRCUIT INTERRUPTER RECEPTACLE

All models (Except HWI3000) have a 120- volt ground fault circuit interrupter (GFCI) receptacle. The GFCI receptacle is on the control panel or top cover of alternator (mod- els MGH3000G, MGH3000, and MGH3000PR only). The GFCI protects you againsthazardouselectricalshockcausedwhen your body becomes a path through which electricity travels to reach ground. This could happen when you touch an appliance or cord that is ‘live’ through faulty mechanism, damp or worn insulation, etc.

When protected by the GFCI, you may still feel a shock, but the GFCI should cut it off quickly. A person in normal health should not receive serious injury. Note: Infants and very small children may still be affected.

Test Procedure

Check the GFCI receptacle every month. This insures it is working right.

1.Push black TEST button. Red RESET button should pop out. This should trip GFCI, resulting in no electrical power at receptacle. Verify this by plugging test lamp with good bulb into recep- tacle. If lamp does not work, GFCI re- ceptacle is good.

WARNING: If RESET button does not pop out, do not use the GFCI receptacle. Contact a quali- fied electrician for repairs.
