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:
Yo u
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.
GROUND FAULT CIRCUIT
INTERRUPTER RECEPTACLE
All models have a 120-volt ground fault cir-
cuit interrupter (GFCI) receptacle. The GFCI
receptacle is on the control panel or top cover
of alternator (MGR2900). 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 TEST button. RESET button
should pop out. This should trip GFCI,
resulting in no electrical power at re-
ceptacle. Verify this by plugging test
lamp with good bulb into receptacle. If
lamp does not work, GFCI receptacle
is good.
WARNING: If RESET button
does not pop out, do not use the
GFCI receptacle. Contact a quali-
fied electrician for repairs.
GENERATOR
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.

VOLTAGE SELECTOR
SWITCH
All models except MGR2900 have a volt-
age 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 watt-
age capacity.
IMPORTANT:
Do not move the voltage
selector switch while powering electrical
items. Unplug all items before moving switch.
Failure to do so can damage switch. Model
MGR2900 does not have this switch. This
model provides full power to all receptacles.
AUTO-IDLE SYSTEM
(Except Model MGR2900)
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.
