DANGER: Carbon monoxide

poisoning may lead to death!

Engine exhaust contains poisonous carbon
monoxide gas. Overexposure will cause loss
of consciousness and will lead to death. Use
only in well-vented areas. Make sure area
has plenty of free-moving, fresh, outside
air. Never run generator in an enclosed or
confined area. Never run generator inside
occupied building.

Carbon Monoxide Poisoning: Early
signs of carbon monoxide poisoning re­semble the flu, with headaches, dizziness,
and nausea. If you have these signs, get
fresh air at once! Some people are more
affected by carbon monoxide than others.
These include pregnant women, persons
with heart or lung disease or anemia, those
under the influence of alcohol, and those at
high altitudes. Make certain you read and
understand all warnings. Keep this manual
for reference. It is your guide to safe and
proper operation of this generator.

1. Gasoline presents a hazard of fire or ex­plosion. Gasoline is flammable. Its va­por is explosive.

•Keep fuel out of children’s reach.

• Refuel generator in a well-vented

area. Do not fill fuel tank in the dark.
Do not refuel while engine is run­ning. Unhook all electrical loads and
shut off engine before refueling.

• Do not overfill fuel tank. Always al-

low room for fuel to expand. If you
overfill tank, fuel can overflow onto
hot generator. This can cause fire or
explosion. After refueling, tightly
close fuel tank cap.

• Do not spill fuel. Fuel or fuel vapor

may ignite. If fuel spills, make sure
area is dry before starting engine.

•Never smoke in refueling area. Never

allow open flames or sparks in area.

• Store fuel in approved container.

Store fuel in a well-vented area free
of open flames or sparks.

2. Guard against fire hazard. Keep opera­tion area well-vented. Keep generator
at least three feet away from any ob­ject. Do not place flammable objects
near generator.

• Do not use generator where flam-

mable vapors are present. Some va­pors are heavier than air. These va­pors settle in low-lying places.

• Do not use generator in enclosed

spaces. This includes motor home or
RV generator compartments.

3.

Guard against electric shock. Generator
produces high voltage. This high voltage
can cause severe electric shock. Only re­sponsible adults should use generator.

PORTABLE GASOLINE GENERATORS

GENERAL
INFORMATION

Master portable generators are rugged and
compact. These generators use brushless
alternators for dependable, trouble-free ser­vice. Honda gasoline engines provide long
life under heavy use. Honda engines have
overhead valves (OHV). This provides high
performance 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.

Additional Features

• Circuit breaker protection

• Spark-arresting muffler (except model
MGH10000A)

• Large fuel tank

• Oil alert system

• Electric starter (models MGH5000DIE,
MGH6500IE, and MGH10000A only)

• 15-Amp ground fault circuit interrupter
(GFCI) receptacle (Except HWI3000
Model)

UNPACKING

1. Remove generator from carton.

2. Remove any protective packaging ap-

plied to generator for shipment.

3. Check for loose or missing parts. Check

for shipping damage. If any parts are
missing or damaged, promptly inform
dealer where you bought generator.

4. Battery cables are supplied for models

MGH5000DIE, MGH6500IE, and
MGH10000A only. These cables are in
a separate bag inside generator carton.

VENTILATION

DANGER: Use only in well­vented areas. Make sure area has
plenty of free-moving, fresh, out­side air. Never run generator in
an enclosed or confined area.
Never run generator inside occu­pied building. Engine exhaust
contains poisonous carbon mon­oxide gas. Overexposure will
cause loss of consciousness and
will lead to death.

This generator needs cooling air to run prop­erly. Never block free-flowing, cooling air
to generator. Overheating will occur with­out cooling air. This will damage the gen­erator. Keep generator at least three feet
away from any object.

DUST, DIRT, RAIN,
AND SNOW

WARNING: Do not use gen­erator outdoors in rain or snow.
Do not use generator near stand­ing water or snow. Do not use if
generator is wet or damp. Oper­ating generator in these condi­tions increases the risk of elec­trocution. Severe injury or death
can occur.

Do not use generator in extremely dusty or
dirty conditions. This will severely affect its
life. Keep generator clean. Do not allow
dust, dirt, rain, or snow to collect on it.
Protect generator from outdoor elements.

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.

FULL POWER SELECTOR
SWITCH

All models except HWI3000, MGH3000G,
MGH3000, MGH3000PR, MGH6500IE,
and MGH10000A have a full power 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 wattage capacity.

IMPORTANT:

Models MGH5000DIE, MGH6500IE, and
MGH10000A have electric starters. A bat­tery is not supplied with generator. You
must provide a 12-volt, 32-amp-hour bat­tery. For more battery information, see Bat-
tery, page 8.

GROUND FAULT CIRCUIT
INTERRUPTER RECEPTACLE

All models (Except HWI3000) have a 120­volt ground fault circuit interrupter (GFCI)
receptacle. The GFCI receptacle is on the
control panel or top cover of alternator (mod­els MGH3000G, MGH3000, and
MGH3000PR only). 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.
very small children may still be affected.

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.

IMPORTANT:

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 genera­tor and powered items.

RECEPTACLE CIRCUIT
BREAKER

The circuit breakers protect the receptacles
and alternator. Overloading generator will
trip circuit breaker. A short circuit in item
being powered will also trip breaker. If this
occurs, unplug electrical load from recep­tacle. Let circuit breaker cool down. Push
circuit breaker button to reset.

Electric motors need higher starting current.
They require up to three-times their rated
wattage to start. The starting current needed
may be too high. This can cause nuisance
circuit breaker tripping. To help prevent
this, start electric motors first. Connect ad­ditional items to generator after starting
motors. If this continues to happen, reduce
the total generator load.

GENERATOR
GROUNDING

WARNING: You must prop­erly earth-ground generator be­fore starting. This will help guard
against deadly electric shock.
Only use grounded plugs with
generator. Only use grounded ex­tension cords. Only use three­wire or double-insulated power
tools.

Grounding generator helps prevent electric
shock from a ground fault condition. Locate
ground lug on end of generator housing (see
Figure 16). Attach a #10 stranded-copper
ground wire to ground lug. Drive grounding
point into ground. Grounding point can be a
stake, grounding rod, or pipe. Grounding
point should be copper or brass. Attach
ground wire to grounding point. You must
supply the ground wire and grounding point.
These do not come with generator. Follow
the National Electrical Code and all state
and local codes. Consult your power com­pany or a licensed electrician.

WARNING: For a grounding
point, do not use metal pipe be­ing used to carry combustible
materials or gases.

STANDBY
INSTALLATION TO
HOME OR
BUILDING

WARNING: Have standby in­stallation performed by a skilled,
licensed electrician. Do not let
anyone else wire into a utility
circuit. Personal injury, equip­ment damage, or damage to home
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.

You may need to use this generator as a
standby power source. During a power out­age, the generator will power selected items
in a building. Have generator and additional
wiring installed by a skilled, licensed elec­trician. This is not a do-it-yourself job. Fol­low all local codes.

WARNING: The electrician
must install a double-throw trans­fer switch. This isolates existing
electrical circuits from the utility
power line. If not isolated, gen­erator output will back-feed into
utility power line. This may elec­trocute a power company line
repair person.

DETERMINING
ELECTRICAL LOAD
FOR GENERATOR

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 watt­age of generator. For rated wattage of your
generator, see Specifications, page 5. Elec­tric motors present a special problem when
figuring load. Read Step 3 carefully.

1. Make two lists of items you want pow­ered 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 ex­cept motors. The light bulb or appliance
nameplate lists its wattage. Remember,
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.

3. Electric motors present a special prob­lem. They require up to three-times
their rated wattage to start. Chart 2,
below, shows starting watts for differ-

ent size motors. For example: an elec­tric 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 re­quire 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.

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.

OWNER’S MANUAL

OPERATION

GENERAL INFORMATION

This generator is not large enough to power
your entire home. Do not connect generator
to any existing electrical circuits. Plug items
directly into generator receptacles. Do not
exceed amperage rating of receptacles. Only
use grounded cords.

DANGER: Use only in well­vented areas. Make sure area has
plenty of free-moving, fresh, out­side air. Never run generator in
an enclosed or confined area.
Never run generator inside occu­pied building. Engine exhaust
contains poisonous carbon mon­oxide gas. Overexposure will
cause loss of consciousness and
will lead to death.

DANGER: Never connect gen­erator to any existing electrical
circuits. The generator output will
back-feed into the utility power
line. This may electrocute a power
company line repair person. Also,
if generator is powering electri­cal circuits, the chance of an elec­trical fire exists.

Note:

We supply the engine owner’s manual
with generator. Refer to that manual for
questions concerning engine operation.

Model MGH10000A also has a 120/240V,
50-amp receptacle (see Figure 17).

OWNER’S MANUAL

Note:

The 250 Volt/50 Amp receptacle
is not connected through the Auto-Idle
circuit. The Auto-Idle switch must be
turned off to get full power out of this
receptacle (see Figure 26).

6. The Auto-Idle system should be turned
OFF when generator is shut down.

Adjusting the Idle Speed

IMPORTANT:

• 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 en­gine. Allow engine to warm up with no
load for five minutes.

WARNING: Always set the idle
speed before turning on the Auto­Idle. 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.

Adjust the idle speed only:

8. Turn Auto-Idle switch ON. Make sure
solenoid is engaged. When engaged, the
punger 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 carburetor
(refer to Carburetor Adjustment in
Honda Engine Manual).

10. Replace the engine linkage cover
(Models MGH4000CI, MGH5000DI,
MGH5000DIE, MGH6000DI, and

loosen bolt that holds the solenoid
mounting bracket to the generator on
Model MGH10000A (see Figure 28).

5. Slowly pull solenoid bracket away from
engine (on Model MGH10000A this will
require bending the bracket slightly).

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 M8 nut to secure solenoid

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:

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 genera­tor. Overloading will trip circuit breaker.

IMPORTANT:

MGH3000, MGH3000PR, MGH6500IE, and
MGH10000A) 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 powering 240V items.

1. Check items to be powered. Their
nameplate lists their wattage ratings.

Note:

trical 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. Re­move voltage sensitive items first. Voltage
sensitive items include TVs, VCRs, and
other home electronic items.

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.

FIVE-YEAR LIMITED WARRANTY

GASOLINE PORTABLE GENERATORS

DESA Specialty Products™ makes no warranty with respect to the engine and engine components not of its manufac­ture. 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 replace­ment 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™
