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 MGH3000 and MGH3000PR only). The
GFCI protects you against hazardous electri-
cal shock caused when 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.

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, MGH3000,
MGH3000PR, MGH7000D, MGH7000DI,
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.
120/240 VOLT: This position sends full power
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, MGH3000, MGH3000PR,
MGH7000D, MGH7000DI, and
MGH10000A do not have this switch. These
models provide full power to all receptacles.
ELECTRIC START
(Models MGH5000DIE,

Models MGH5000DIE, MGH7000D,
MGH7000DI, and MGH10000A have elec-
tric starters. A battery is not supplied with
generator. You must provide a 12-volt, 32-
amp-hour battery. For more battery infor-
mation, see Battery, page 8.

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