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.

Figure 2 - Engine Switch Location

VOLTAGE SELECTOR SWITCH

All models except MGR2900A have a voltage 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: Do not move the voltage selector switch while powering electrical items. Unplug all items before moving switch. Failure to do so can damage switch. Model MGR2900A does not have this switch. This model provides full power to all receptacles.

AUTO-IDLE SYSTEM

(Except Model MGR2900A)

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.

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 (MGR2900A). 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 TEST button. RESET button should pop out. This should trip GFCI, result ing 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 quali ﬁed 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 recep tacle. 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.

Note: High ambient temperature will cause nuisance tripping.

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 doub le-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.

Grounding generator helps prevent electric shock from a ground fault condition. Follow these steps to ground your generator:

1. Locate ground bolt on generator hous ing (see Figure 7).

2. Loosen SEM nut on ground bolt. Note: Do not remove SEM nut from bolt.

3. Attach a spade connector to the end of a #10-8 stranded-copper ground wire.

4. Attach spade connector to ground bolt between ﬂat washer and SEM nut (see Detail A in Figure 7).

OWNER’S MANUAL

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 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,

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.

you must use the starting watts ﬁgure. Do not use the running watts ﬁgure.

Adjusting the Idle Speed (Models MGR4500I and MGR6000I)

IMPORTANT: Adjust the idle speed only:

• If the idle speed becomes too high.

• If the engine idle speed will not regulate (engine wants to “hunt” or speeds up and slows down repeatedly).

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 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.

2. Loosen the two m10 bolts mounting the solenoid to the engine (see Figures 16 and 17).

3. Connect a volt meter to the 120-volt duplex receptacle.

4. Fully push plunger into the solenoid body (to manually engage solenoid) and slowly slide solenoid back until the engine is running at the proper idle speed. At proper idle speed (2800 minimum RPM), the meter should read 45-55 Volts. Lower settings will cause the Auto-Idle to not operate properly.

5. After reaching proper idle speed, tighten M10 bolts to secure solenoid.

6. Turn Auto-Idle switch ON. Make sure solenoid is engaged. When engaged, the punger is pulled back into the solenoid.

7. 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 the throttle (refer to engines operation in Engine Manual).

OPERATION

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.

IMP O R T A NT: (All m o d els ex c e p t MGR2900A) Keep voltage 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: 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,

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.

page 9.

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 18).

4. Turn fuel valve lever off except on Model MGR6000I. Do this by moving valve lever fully to the left (see Figure 19).

Figu re 18 - Engine Switch I n OFF Position

Fuel Valve Lever (Off Position)

Figure 19 - Fuel Valve Lever Off (Model MGR4500I Shown)

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 en gine 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.

IMPORTANT: Keep generator level when servicing. Never turn generator upside 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.

STORAGE

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: Keep generator level while in storage. Never store generator upside down or standing on end.

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

TROUBLESHOOTING

Use a fuel additive, such as STA-BIL® or an equivalent, when storing generator 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.
