GROUND FAULT CIRCUIT
INTERRUPTER RECEPTACLE
All models (Except HWI3000A) 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 MGH3000GA and MGH3000A only).
The GFCI protects you against hazardous
electrical 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
receptacle 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.

MGH6500AIE 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
HWI3000A, MGH3000GA, MGH3000A, and
MGH6500AIE do not have this switch. These
models provide full power to all receptacles.
ELECTRIC START
(Models MGH5000EIE and
MGH6500AIE)
Models MGH5000EIE and MGH6500AIE
have electric starters. A battery is not sup-
plied with generator. You must provide a 12-
volt, 32-amp-hour battery. For more battery
information, 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 gen-
erator 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
generator and powered items.
WARNING: If RESET button
does not pop out, do not use the
GFCI receptacle. Contact a quali-
fied electrician for repairs.
