Under this heading, installation, operat-

ing, and maintenance procedures or practices will be found that, if not carefully followed, MAY result in minor personal injury, product or property damage.

Engine exhaust contains poisonous

carbon monoxide gas. Overexposure will cause loss of consciousness and will lead to death. 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.

Early signs of carbon monoxide poisoning resemble the flu, with headaches, dizziness, or 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.

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 allow room for fuel to expand. If you overfill tank, fuel can overflow onto hot generator or engine surface. 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.

See engine owner’s manual for more information.

FULL POWER SELECTOR SWITCH

All models except 3W735B, 3WY47, and 3WY45 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.

Figure 5 – Full Power Selector Switch in 120 Volt Only Position

120/240 VOLT: This position sends full power to the 120/240V receptacle. It also powers the 120V receptacles at reduced wattage capacity.

Figure 6 – Full Power Selector Switch in 120/240 Volt Position

IMPORTANT: Do not move the full power selector switch while powering electrical items. Unplug all items before moving switch. Failure to do so can damage switch.

Models 3W735B, 3WY45, and 3WY47 do not have this switch. These models provide full power to all receptacles.

HOUR METER

All models except 3W735B have an hour meter. The hour meter is on the control panel. The hour meter shows the total generator run time, including all idle time (See Figure 7). Hour meter is accurate up to 1/10 of an hour.

Figure 7 – Hour Meter

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 (MODELS 3WY46, 3WY45, AND 3WY47 ONLY)

Models 3WY46, 3WY45, and 3WY47 have an electric starter. A battery is not supplied with generator. You must provide a 12volt, 32-amp-hour battery. For more battery information, see “Battery,” page 8.

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 3W735B 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.

Figure 10 – Receptacle Circuit Breaker Button

Electric motors need higher starting current. They require up to 3 to 6-times their rated full-load 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 temperatures will cause nuisance tripping.

FUEL

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 allow room for fuel to expand. If you overfill tank, fuel can overflow onto hot engine. 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.

Use clean, fresh, unleaded gasoline. Use gasoline with octane rating of 86 or higher. Service station gasoline pumps should display the octane rating. Using gasoline with lower octane level could damage engine. Avoid getting dirt, dust, or water in fuel tank. Do not mix oil with gasoline. See engine owner’s manual for more information.

ENGINE OIL

We ship the generator without oil in the engine crankcase. You must add oil before starting engine. See engine owner’s manual for specific oil type.

CHECKING OIL LEVEL AND ADDING OIL

Follow steps below to check oil level. Make sure engine is level and stopped.

1.Remove dipstick (See Figure 19). Wipe dipstick clean.

2.Insert dipstick into oil filler neck. Do not screw it in. Oil level should be at top of filler neck. Oil should cover most of dipstick. For Model 3WY47 only, oil level should be between two dots on dipstick.

3.If level is low, fill to top of oil filler neck (See Figure 19). Only use oil recommended in engine owner’s manual. For Model 3WY47 only, fill to top dot on dipstick.

NOTE: If oil level is too low, oil alert system will shutdown engine and prevent engine from restarting.

VENTILATION

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.

GENERATOR GROUNDING

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 three-wire 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 20). 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.

For a grounding point, do not use

metal pipe being used to carry combustible materials or gases.

GROUND FAULT PROTECTION

Ground Fault Circuit Interrupter (GFCI) helps guard against electric shock. On

construction sites, you must use a GFCI. United States OSHA and the National Electric Code requires this.

You may need to provide the GFCI device. Purchase GFCI at any electrical supply house. Check the Yellow Pages for the nearest supply house.

STANDBY INSTALLATION TO HOME OR BUILDING

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 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.

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 “Electrical Specifications,” page 2. 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 3 to 6 times their rated full load wattage to start. Chart 1, on page 12, shows starting watts (maximum volt-amperes [VA]) 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 (maximum VA) needed. 600 watts x 3 = 1800 watts (VA) to start. When figuring the generator load for motors, you must use the starting watts (maximum VA) figure. Do not use the running watts figure.

Installation (Continued)

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 2 for typical appliance wattage examples.

4.Add watts and starting watts (maximum VA) 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.
