GROUND FAULT CIRCUIT INTERRUPTER RECEPTACLE

All models have a 120-volt ground fault circuit interrupter (GFCI) receptacle. The GFCI receptacle is on the control panel or top cover of alternator (model MGH3000 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.

Note:

Infants and very small children may still be affected.

Test Procedure

Check the GFCI receptacle every month. This insures it is working right.

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 receptacle. If lamp does not work, GFCI receptacle is good.

WARNING

If RESET button does not pop out, do not use the GFCI receptacle. Contact a qualified electrician for repairs.

2. If the GFCI receptacle tests okay, restore power by pushing the RESET button back in. The test lamp should work at this time.

IMPORTANT:

You must press the RESET button firmly and fully. It should lock into place. If the GFCI does not lock into place, do not use receptacle. Contact a qualified electrician for repairs.

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.

ENGINE OIL

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:

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 can 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.

This generator will not power your entire home. Most home utility

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 7. 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

DETERMINING

ELECTRICAL

LOAD FOR

GENERATOR

Continued

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 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. 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.

PRESTART

Operate generator on a firm, dry, and clean surface. The surface must be level. Protect generator from heavy dust, sand, dirt, rain, or snow. Do not locate generator near standing water and snow. Make sure area is well-vented.

WARNING

Only responsible adults should use generator. Never let anyone operate generator without proper instructions.

Note:

If oil level is too low, oil alert system will keep engine from starting (see Oil Alert

System, page 9). Make sure oil level is full before starting. See Engine Oil, page 11.

Before starting the engine, disconnect all electric loads from generator.

STARTING

IMPORTANT:

tion. Do not adjust throttle. Preset position lets engine 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.

The engine speed is preset. The throttle is locked in preset posi-

IMPORTANT:

before adding electrical loads.

1. Make sure gasoline tank is full. See Fuel, page 12 for fuel information.

2. Move fuel valve lever to the ON position (see Figure 15).

3. Move choke lever fully to the left (see Figure 15). This closes the choke.

Note:

high.

Never start generator with electrical loads connected. Start engine

4. Start the engine.

A. Recoil Starter

Turn engine switch to the ON position (see Figures 16 and 17). Remove slack from starter rope by lightly pulling starter grip. Next, pull starter rope briskly.

IMPORTANT:

Do not let starter grip snap back against engine. Return it gently.

This will prevent damage to starter.

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 9.

B. Electric Starter (Model MGH7000 Only)

Turn the engine switch to the START position (see Figure 17). Hold it there until engine starts. When engine starts, let switch return to the ON position.

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.

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 9.

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:

cal 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:

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:

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 16.

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.

Do not overload generator. Make sure total wattage of all electri-

(All models except MGH3000 and MGH7000) Keep full power

The wattage ratings for some electrical motors are misleading. They

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.

STOPPING ENGINE

IMPORTANT:

tion. Do not adjust throttle. Follow the steps below to stop engine.

1. Remove all electrical loads from generator (see Disconnecting Electrical Loads, page 22). Remove electrical loads one at a time.

2. Let engine run for two or three minutes after removing electrical loads. This lets engine cool slightly.

3. Turn engine switch to the OFF position (see Figure 19).

4. Turn fuel valve lever off. Do this by moving valve lever fully to the left (see Figure 20).

MAINTENANCE

AND REPAIRS

WARNING

Only a qualified electrical service person should service and repair the alternator on this generator. Use only factory approved replacement parts.

CAUTION

The engine speed is preset. The throttle is locked in preset position. Do not adjust throttle. Preset position lets engine 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.

CAUTION

Shut off generator before performing maintenance.

STORAGE

IMPORTANT:

down or stand it on end to service.

Note:

We supply the engine owner’s manual with generator. Refer to that manual

for questions concerning engine maintenance and repairs. Non-engine parts require little maintenance. Keep generator clean. Use a damp

cloth to clean outside surfaces. Never use water to clean generator. Water can cause damage to internal parts. Use vacuum to clean air inlet and outlet louvers of alternator.

Keep generator level when servicing. Never turn generator upside

WARNING

Remove all fuel from fuel tank before storing generator. Store fuel in approved container. Store fuel in a well-vented area free of open flames or sparks.

WARNING

The muffler becomes very hot during operation. The muffler remains hot for a while after shutdown. Let engine cool before storing.

IMPORTANT:

down or standing on end.

Note:

We supply the engine owner’s manual with generator. Refer to that manual

for questions concerning engine storage. Use a fuel additive, such as STA-BIL

with fuel in fuel tank. This will minimize fuel gum deposits from forming in engine.

Cover and store generator in a clean, dry place. Do not expose generator to extreme high or low temperatures during storage.

Keep generator level while in storage. Never store generator upside

or an equivalent, when storing generator

TWO-YEAR LIMITED WARRANTY

GASOLINE PORTABLE GENERATORS

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 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.

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.
