INFORMATION
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 generators use brushless
alternators for dependable, trouble-free ser-
vice. Honda gasoline engines provide long
life under heavy use. Honda engines have
overheadvalves(OHV). Thisprovideshigh
performance with lower fuel consumption.
These engines are governed to maintain
enginespeedof3600RPMunderload.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.

FEATURES
(Models MGH5000DIE,
MGH6500IE, and MGH10000A)
Models MGH5000DIE, MGH6500IE, and
MGH10000A have electric starters. A bat-
tery is not supplied with generator. You
must provide a 12-volt, 32-amp-hour bat-
tery. For more battery information, see Bat-
tery, page 8.
OIL ALERT SYSTEM
Theoilalertsystemprotectstheenginefrom
low oil damage. This system automatically
shuts down the engine and prevents engine
restarting if the oil level falls too low.
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.
Note:Whenthishappens, theengineswitch
remains in the ON position. The oil alert
system is wired into the ON/OFF Switch.
GROUND FAULT CIRCUIT
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 MGH3000G, MGH3000, and
MGH3000PR only). The GFCI protects you
againsthazardouselectricalshockcausedwhen
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.
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
selector switch while powering electrical
items.Unplugallitemsbeforemovingswitch.
Failure to do so can damage switch. Models

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

Test Procedure
Check the GFCI receptacle every month.
This insures it is working right.
Figure 3 - Full Power Selector Switch
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.

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.
STANDBY
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.
INSTALLATION TO
HOME OR
BUILDING
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.
2. Enter running watts of each item ex-
cept motors. The light bulb or appliance
nameplate lists its wattage. Remember,
1KW = 1000 watts. Note: The name-
plate 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.
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.

toryapprovedreplacementparts.
1. Check items to be powered. Their
nameplate lists their wattage ratings.
Model
MGH3000PR
Note: The wattage ratings for some elec-
trical motors are misleading. They may
require up to three-times their rated watt-
age to start. You must figure total electri-
cal 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.
CAUTION: The engine speed
is preset. The throttle is locked in
preset position. Do not adjust
throttle. Preset position lets en-
gine run at 3600 RPM under load.
The engine must maintain 3600
RPM for generator to create cor-
rect voltage. Running engine at
lower speeds will damage gen-

FIVE-YEAR LIMITED WARRANTY
GASOLINE PORTABLE GENERATORS
DESA Specialty Products™ makes no warranty with respect to the engine and engine components not of its manufac-
ture. They are subject to warranties of their manufacturers. Honda warrants the engine. See engine owner’s manual
for engine warranty information.
DESA Specialty Products™ warrants each generator, excluding engine, of its manufacture, to be free from defects in
material and workmanship for five 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.
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 five years from the date of first purchase, and DESA
Specialty Products’™ liability is hereby limited to the purchase price of the product and DESA Specialty Products™
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.
