FEATURES

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.

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: A minimum current load of 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.

ELECTRIC START

A battery is not supplied with generator. You must provide a 12-volt, 32-amp-hour battery. For more battery information, see Battery, page 8.

GROUND FAULT CIRCUIT INTERRUPTER RECEPTACLE

The GFCI receptacle is on the control panel. 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.

ENGINE CIRCUIT BREAKER

This fuse protects the battery charging circuit. A short circuit will trip the break the fuse. The fuse will also break if you install battery wrong. Replace fuse if engine will not start. The fuse is located inside of the keyswitch box.

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.

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 out age, 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 ex isting 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 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.

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 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 5). Make sure oil level is full before starting. See Engine Oil, page 7.

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

STARTING

IMPORTANT: 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.

IMPORTANT: Never start generator with electrical loads connected. Start engine before adding electrical loads.

1. Make sure gasoline tank is full. See Fuel, page 7 for fuel information.

2. Pull choke button out (see Figure 17). This closes the choke.

Note: You may not need to close choke

if engine is warm or air temperature is high.

3. Start the engine.

Turn the engine switch to the START position (see Figure 18). 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 5.

4. As engine warms up, the choke will automatically open.

AUTO-IDLE OPERATION

IMPORTANT: Never start engine with electrical loads connected. Start engine before adding electrical loads.

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. Turn Auto-Idle switch ON. Engine will slow to idle speed. Engine idle speed is preset. Idle speed adjustment should not be necessary.

4. Operate generator according to speciﬁcations outlined in owner's manual.

5. Engine will automatically increase to normal operating speed when you plug load into any generator outlet.

MGH8500AIE

Note: MGH10000C Only - The 250

Volt/50 Amp receptacle is not con nected through the Auto-Idle circuit. The Auto-Idle switch must be turned off to get full power out of this receptacle (see Figure 19).

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

Adjusting the Idle Speed

IMPORTANT: Adjust the idle speed only:

• 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.

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: Do not overload generator. 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.

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

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.

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.

STOPPING ENGINE

IMPORTANT: The engine speed is preset. The throttle is locked in preset position. Do not adjust throttle.

Follow the steps below to stop engine.

1. Remove all electrical loads from generator (see Disconnecting Electrical Loads). 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 21).

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™ 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.
