WARNING: Always set the idle
speed before turning on the Auto-
Idle. If idle speed is not set, the
larger resistor on the control board
may become hot. Heat from the
resistor may damage the protective
coating on the control board.

Adjusting the Idle Speed
IMPORTANT: Adjust the idle speed only:
• If the idle speed becomes too high.
• If the engine idle speed will not regulate (en-
gine idles and speeds up again and again).
1. Turn Auto-Idle switch OFF. Start en-
gine. Allow engine to warm up with no
load for five minutes.
2. Remove engine linkage cover (Mod-
els MGH4000DI, MGH5000EI,
MGH5000EIE, and MGH6500AIE).
3. Push plunger into solenoid body to manu-
ally engage solenoid and set idle speed.
4. Loosen nut that holds the solenoid
mounting bracket to the generator
(Models MGH4000DI, MGH5000EI,
MGH5000EIE, and MGH6500AIE.
See Figure 20).
5. Slowly pull solenoid bracket away from
engine.
6. With a volt meter, check the no-load
output voltage at the 120-volt duplex
receptacle. At proper idle speed (2680
minimum RPM) the meter should read
50-60 volts. Lower settings will cause
the Auto-Idle to not operate properly.
7. After reaching proper idle speed,
tighten nut to secure solenoid mount-
ing bracket (Models MGH4000DI,
MGH5000EI, MGH5000EIE, and
MGH6500AIE (see Figure 20).
8. Turn Auto-Idle switch ON. Make sure
solenoid is engaged. When engaged, the
plunger is pulled back into the solenoid.
9. If the engine speed is too slow, the
engine will want to "hunt" or speed
up and slow down repeatedly. When
this occurs, increase engine speed by
adjusting throttle stop screw on carbu-
retor (refer to Carburetor Adjustment
in Honda Engine Manual).
10. Replace the engine linkage cover
(Models MGH4000DI, MGH5000EI,
MGH5000EIE, and MGH6500AIE).
HIGH ALTITUDE OPERATION
This generator will not perform well at high
altitudes without proper adjustment. See
engine owner’s manual for details.
ADDING ELECTRICAL
LOADS
IMPORTANT: Do not overload generator.
Make sure total wattage of all electrical loads
does not exceed rated wattage of generator.
Overloading may shorten generator life. It
could also cause internal damage to genera-
tor. Overloading will trip circuit breaker.
IMPORTANT: ( A l l m o d e l s ex -
cept HWI3000A, MGH3000A, and
MGH6500AIE) Keep full power selector
switch in the 120 VOLT ONLY position
if only powering 120V items. Only move
switch to 120/240 VOLT position if power-
ing 240V items.
1. Check items to be powered. Their
nameplate lists their wattage ratings.
Note: The wattage ratings for some
electrical motors are misleading. They
may require up to three-times their
rated wattage to start. You must figure
total electrical load wattage. Make sure
total wattage of all electrical loads does
not exceed rated wattage of generator.
See Determining Electrical Load For
Generator,
page 10.
2. Start engine. Let engine reach full
speed.
3. Connect electrical loads one at a time.
If the load consists of electric motors,
start them first. Always start the largest
first. Start each motor individually.
DISCONNECTING ELECTRIC
LOADS
Remove electrical loads one at a time. Re-
move voltage sensitive items first. Voltage
sensitive items include TVs, VCRs, and other
home electronic items.
