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
(model MGH3000 only). The GFCI pro-
tects 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 insula-
tion, 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.
2. If the GFCI receptacle tests okay, re-
store power by pushing the RESET
button back in. The test lamp should
work at this time
. IMPORTANT: You
must press the RESET button firmly
and fully. It should lock into place. If
the GFCI does not lock into place, do
not use receptacle. Contact a qualified
electrician for repairs.

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.

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.

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, MGH7000D,
MGH7000DI, and MGH10000A do not have
this switch. These models provide full power
to all receptacles.
