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.

Generator 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 10).

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.

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.

TrippedNormal

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.

Installation

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.

Oil Level At Top Of Filler Neck

Figure 19 – Checking Oil Level (Model 3W735B Shown)

NOTE: If oil level is too low, oil alert

system will shutdown engine and prevent engine from restarting.

VENTILATION

Use only in well-

vented 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 doublethrow 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.

Operation (Continued)

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.

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 10.

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 10 for fuel information.

2. Move fuel valve lever to the ON position

(See Figure 24).

3. Move choke lever fully to the left (See

Figure 24) or pull choke button out (Model 3WY47 only, See Figure 25). This closes the choke.

NOTE: You may not need to close choke if engine is warm or air temperature is high.

4. Start the engine.

Choke Lever (Open Position)

Figure 28 – Choke Lever Opened

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.

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.

NOTE: The 250 Volt/50 Amp receptacle is not connected through the auto-idle circuit. The auto-idle switch must be turned off to get full power out of this receptacle (See Figure 30).

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 (engine 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.

2. Remove engine linkage cover (Models 3WY46 and 3WY45 only).

3. Push plunger into solenoid body to manually engage solenoid and set idle speed.

4. Loosen the M8 nut that holds the solenoid mounting bracket to the generator (Models 3WY46 and 3WY45 only, See Figure 31). Do not loosen bolt that holds the solenoid mounting bracket to the generator on Model 3WY47, See Figure 32).

Operation (Continued)

Always set the idle

speed before turning on the auto-idle. 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.

5. Slowly pull solenoid bracket away from engine (on Model 3WY47 this will require bending the bracket slightly).

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.

7. After reaching proper idle speed, tighten M8 nut to secure solenoid mounting bracket (Models 3WY46 and 3WY45 only).

8. Turn auto-idle switch ON. Make sure solenoid is engaged. When engaged, the plunger is pulled back into the solenoid.

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 carburetor (refer to Carburetor Adjustment in Honda Engine Manual).

10. Replace the engine linkage cover (Models 3WY46 and 3WY45 only).

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.

IMPORTANT: 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 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 3 to 6 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 11.

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,” above). 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 Figures 33 and 34).

Dayton Professional-Duty Electric Generators

NOTE: The five-year limited warranty below covers all non-engine parts of this generator including the alternator. Honda warrants the

engine. See engine owner’s manual for engine warranty information.

LIMITED WARRANTY

DAYTON FIVE-YEAR LIMITED WARRANTY. Dayton Professional-Duty Electric Generators, Models covered in this manual, are warranted by Dayton Electric Mfg. Co. (Dayton) to the original user against defects in workmanship or materials under normal use for one year after date of purchase. Any part which is determined to be defective in material or workmanship and returned to an authorized service location, as Dayton designates, shipping costs prepaid, will be, as the exclusive remedy, repaired or replaced at Dayton’s option. For limited warranty claim procedures, see PROMPT DISPOSITION below. This limited warranty gives purchasers specific legal rights which vary from jurisdiction to jurisdiction.

LIMITATION OF LIABILITY. To the extent allowable under applicable law, Dayton’s liability for consequential and incidental damages is expressly disclaimed. Dayton’s liability in all events is limited to, and shall not exceed, the purchase price paid.

WARRANTY DISCLAIMER. Dayton has made a diligent effort to provide product information and illustrate the product in this literature accurately; however, such information and illustrations are for the sole purpose of identification, and do not express or imply a warranty that the products are MERCHANTABLE, or FIT FOR A PARTICULAR PURPOSE, or that the products will necessarily conform to the illustrations or descriptions. Except as provided below, no warranty or affirmation of fact, expressed or implied, other than as stated in “LIMITED WARRANTY” above is made or authorized by Dayton.

PRODUCT SUITABILITY. Many jurisdictions have codes and regulations governing sales, construction, installation, and/or use of products for certain purposes, which may vary from those in neighboring areas. While Dayton attempts to assure that its products comply with such codes, it cannot guarantee compliance, and cannot be responsible for how the product is installed or used. Before purchase and use of a product, review the product applications, and all applicable national and local codes and regulations, and be sure that the product, installation, and use will comply with them.

Certain aspects of disclaimers are not applicable to consumer products; e.g., (a) some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you; (b) also, some jurisdictions do not allow limitations on how long an implied warranty lasts, consequently the above limitation may not apply to you; and (c) by law, during the period of this Limited Warranty, any implied warranties of implied merchantability or fitness for a particular purpose applicable to consumer products purchased by consumers, may not be excluded or otherwise disclaimed.

PROMPT DISPOSITION. Dayton will make a good faith effort for prompt correction or other adjustment with respect to any product which proves to be defective within limited warranty. For any product believed to be defective within limited warranty, first write or call dealer from whom product was purchased. Dealer will give additional directions. If unable to resolve satisfactorily, write to Dayton at address below, giving dealer’s name, address, date and number of dealer’s invoice, and describing the nature of the defect. Title and risk of loss pass to buyer on delivery to common carrier. If product was damaged in transit to you, file claim with carrier.
