DANGER: Use only in well-  
ventedareas.Makesureareahas  
plenty of free-moving, fresh, out-  
side air. Never run generator in  
an enclosed or confined area.  
Never run generator inside occu-  
pied building. Engine exhaust  
containspoisonouscarbonmon-  
oxide gas. Overexposure will  
causelossofconsciousnessand  
will lead to death.  
Master portable generators are rugged and  
compact. These models provide depend-  
able, trouble-free service. The alternators  
are brushless with revolving fields. Honda  
gasoline engines provide long life under  
heavy use. Honda engines have overhead  
valves (OHV). This provides high perfor-  
mance with lower fuel consumption. These  
engines are governed to maintain engine  
speed of 3600 RPM under load. 3600 RPM  
engine speed provides 120/240V, 60 Hz  
power.  
Air temperature affects generator output.  
Output drops 1% for each 10° temperature  
rise above 60° F. Very low temperatures may  
make the engine hard to start. See engine  
owner’s manual for more information.  
Thisgeneratorneedscoolingairtorunprop-  
erly. Never block free-flowing, cooling air  
to generator. Overheating will occur with-  
out cooling air. This will damage the gen-  
erator. Keep generator at least three feet  
away from any object.  
Additional Features  
• Circuit breaker protection  
• Spark-arresting muffler (except model  
MGH10000A)  
• Large fuel tank  
• Oil alert system  
• Electric starter (models MGH5000DIE,  
MGH7000D, MGH7000DI, and  
MGH10000A only)  
WARNING: Do not use gen-  
erator outdoors in rain or snow.  
Do not use generator near stand-  
ing water or snow. Do not use if  
generator is wet or damp. Oper-  
ating generator in these condi-  
tions increases the risk of elec-  
trocution. Severe injury or death  
can occur.

INTERRUPTER RECEPTACLE  
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).  
120/240VOLT:Thispositionsendsfullpower  
to the 120/240V receptacle. It also powers the  
120Vreceptaclesatreducedwattagecapacity.  
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.Thiscouldhappenwhenyoutouchan  
appliance or cord that is ‘live’ through faulty  
mechanism, damp or worn insulation, etc.  
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.  
IMPORTANT: Do not move the full power

items.Unplugallitemsbeforemovingswitch.  
Failure to do so can damage switch. Models

MGH10000A do not have this switch. These  
models provide full power to all receptacles.  
When protected by the GFCI, you may still

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.  
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.

ent size motors. For example: an elec-  
tric motor nameplate states 5 amps at  
120 volts. 5 amps x 120 volts = 600  
watts running. Multiply this figure by  
3. This will show the starting watts  
needed. 600 watts x 3 = 1800 watts to  
start. When figuring the generator load  
for motors, you must use the starting  
watts figure. Do not use the running  
watts figure. Note: Some motors re-  
quire nearly the same wattage to run as  
to start. These items include saws,  
drills, hair dryers, and food mixers. See  
Chart 1 for typical appliance wattage  
examples.  
1. Make two lists of items you want pow-  
ered by generator. List all motors and  
motor powered appliances in one. List  
all lights, small appliances, etc. in the  
other. For standby service to home or  
building, only include items you must  
power.  
2. Enter running watts of each item ex-  
cept motors. The light bulb or appli-  
ance nameplate lists its wattage. Re-  
member, 1KW = 1000 watts. Note:The  
nameplate may not list wattage. It may  
only list volts and amps. The formula  
for finding wattage is: Volts x Amps =  
Watts. For example: An appliance  
nameplate states 3 amps at 120 volts. 3  
amps x 120 volts = 360 watts.  
WARNING: Have standby in-  
stallation performed by a skilled,  
licensed electrician. Do not let  
anyone else wire into a utility  
circuit. Personal injury, equip-  
mentdamage,ordamagetohome  
could occur.  
IMPORTANT: This generator will not  
power your entire home. Most home utility  
electric service is more than 60 amps. This  
will exceed generator output. Only power  
needed items during a power outage. Make  
sure total wattage of electrical load does not  
exceed rated wattage of generator.  
4. Add watts and starting watts of all  
items. This total must not be larger than  
the rated wattage of your generator. It  
is a good idea to have up to 25% extra  
capacity for future needs or extra  
equipment.  
3. Electric motors present a special prob-  
lem. They require up to three-times  
their rated wattage to start. Chart 2,  
below, shows starting watts for differ-  
You may need to use this generator as a  
standby power source. During a power out-  
age, the generator will power selected items  
in a building. Have generator and additional  
wiring installed by a skilled, licensed elec-  
trician. This is not a do-it-yourself job. Fol-  
low all local codes.

You must decide what electrical load your  
generator can power. Do this before using  
generator. Use the following four-step  
method. It will help you select a load that is  
not too large. Make sure total wattage of all  
electrical loads does not exceed rated watt-  
age of generator. For rated wattage of your  
generator, see Specifications, page 5. Elec-  
tric motors present a special problem when  
figuring load. Read Step 3 carefully.

Model  
Serial No.  
Date Purchased  
Always specify model and serial numbers when communicating with the factory.  
We reserve the right to amend these specifications at any time without notice. The only warranty applicable is our standard  
written warranty. We make no other warranty, expressed or implied.  
Note: The two-year limited warranty below covers all non-engine parts of this generator including the alternator. Honda  
warrants the engine. See engine owner’s manual for engine warranty information.  
DESA International warrants each alternator, generator, or electric product of its manufacture, to be free from defects  
in material and workmanship for two years from the date of first purchase from an authorized dealer, provided that the  
product has been properly installed, maintained, and operated in accordance with all applicable instructions. The bill  
of sale or proof of purchase must be presented at the time a claim is made under this warranty.  
This warranty is extended only to the original retail purchaser. This warranty covers only the parts and labor required  
to restore this unit to its proper operating condition. Warranty parts must be obtained through factory authorized  
dealers and service centers for this product. These dealers and service centers will provide original factory replace-  
ment parts. Failure to use original factory replacement parts voids this warranty.  
This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that  
fail or become damaged as a result of misuse, abuse, negligence, accident, lack of proper maintenance, alteration,  
modification, tampering, contaminated fuels, repair using improper parts, or repair by anyone other than an authorized  
dealer or service center. Routine maintenance is the responsibility of the owner. Travel, handling, transportation, and  
incidental costs associated with warranty repairs are not reimbursable under this warranty and are the responsibility of  
the owner.  
DESA International makes no warranty with respect to the engine and engine components not of its manufacture.  
They are subject to warranties of their manufacturers.  
To the full extent allowed by the law of the jurisdiction that governs the sale of the product, this express warranty  
excludes any and all other expressed warranties and limits the duration of any and all implied warranties, including  
warranties of merchantability and fitness for a particular purpose to two years from the date of first purchase, and  
DESA International’s liability is hereby limited to the purchase price of the product and DESA International shall not  
be liable for any other damages whatsoever including indirect, incidental, or consequential damages.  
Some states do not allow limitation of how long an implied warranty lasts or an exclusion or limitation of incidental  
or consequential damages, so the above limitation of damages may not apply to you.  
This warranty provides the original purchaser with specific rights. For information regarding those rights, please  
consult the applicable state laws.
