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

overhead valves (OHV). This provides high

performance with lower fuel consumption.

All models except HWI3000A,

MGH3000GA, MGH3000A and

have electric starters. A battery is not sup-

plied with generator.You must provide a 12-

volt, 32-amp-hour battery. For more battery

information, see Battery, 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

All models (Except HWI3000A) 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 MGH3000GA and MGH3000A 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.

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

120V receptacles at reduced wattage capacity.

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

Do not use the running watts ﬁgure.

2. Enter running watts of each item except

motors. The light bulb or appliance

nameplate lists its wattage. Remem-

ber, 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.

DETERMINING

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.

ELECTRICAL LOAD

FOR GENERATOR

You must decide what electrical load your

generator can power. Do this before us-

ing 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.

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 different

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.

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.

position (see Figure 17). Hold it there

until engine starts.When engine starts, let

switch return to the ON position.

AUTO-IDLE OPERATION

IMPORTANT:Neverstartenginewithelec-

trical loads connected. Start engine before

adding electrical loads.

STARTING

IMPORTANT: The engine speed is preset.

The throttle is locked in preset position. Do

notadjustthrottle.Presetpositionletsengine

run at 3600 RPM under load. The engine

must maintain 3600 RPM for generator to

create correct voltage. Running engine at

lower speeds will damage generator and

powered items.

IMPORTANT: Do not use electric

starter more than ﬁve seconds. Starter

motor damage may occur. If engine

fails to start, release the switch and

wait ten seconds.After ten seconds, try

starting again.

1. If engine is cold, turn the Auto-Idle

switch OFF (see Figure 19).

2. Start engine. Allow engine to warm up

with no load for ﬁve minutes.

3. TurnAuto-Idle switch ON. Engine will

slow to idle speed. Engine idle speed

is preset. Idle speed adjustment should

not be necessary.

Note: If engine does not start, check

the oil in the crankcase. Add oil as

necessary. Be sure engine is on a level

surface. See Oil Alert System, page 6.

IMPORTANT: Never start generator with

electrical loads connected. Start engine

before adding electrical loads.

4. Operate generator according to speci-

ﬁcations outlined in owner's manual.

1. Make sure gasoline tank is full. See

5. As engine warms up, slowly move

choke lever fully to the right (see Figure

18). This opens the choke.

plunger is pulled back into the solenoid.

ADDING ELECTRICAL

LOADS

IMPORTANT: Do not overload generator.

Makesuretotalwattageofallelectricalloads

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.

• If the idle speed becomes too high.

• Iftheengineidlespeedwillnotregulate(en-

gine idles and speeds up again and again).

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).

1. Turn Auto-Idle switch OFF. Start en-

gine. Allow engine to warm up with no

load for ﬁve minutes.

WARNING: Always set the idle

speed before turning on the Auto-

Idle. If idle speed is not set, the

largerresistoronthecontrolboard

may become hot. Heat from the

resistormaydamagetheprotective

coating on the control board.

IMPORTANT: (All models 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.

10. Replace the engine linkage cover

(Models MGH4000DI, MGH5000EI,

MGH5000EIE, and MGH6500AIE).

Solenoid Mounting Bracket

Nut

1. Check items to be powered. Their

nameplate lists their wattage ratings.

2. Remove engine linkage cover (Mod-

els MGH4000DI, MGH5000EI,

MGH5000EIE, and MGH6500AIE).

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.

3. Pushplungerintosolenoidbodytomanu-

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.

2. Start engine. Let engine reach full

speed.

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.

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.

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 deal-

ers 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 war-

ranties 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 con-

sult the applicable state laws.
