BEFORE STARTING THE

ENGINE

Add Oil

CAUTION! Any attempt to crank or start the engine

before it has been properly filled with the recommended oil may result in an engine failure.

To fill your engine with oil:

• Place generator on a level surface.

• Follow the oil grade recommendations and oil fill

instructions given in the engine owner’s manual.

NOTE:The generator’s revolving field rides on a prelubricated and sealed ball bearing that requires no additional lubrication for the life of the bearing.

Add Gasoline

WARNING! Never fill fuel tank indoors. Never

fill fuel tank when engine is running or hot.Allow unit to cool for two minutes before refueling. Do Not light a cigarette or smoke when filling the fuel tank.

WARNING! Do Not overfill the fuel tank.

Always allow room for fuel expansion.

• Use regular UNLEADED gasoline with the generator engine. Do Not use premium gasoline. Do Not mix oil with gasoline.

• Clean area around fuel fill cap, remove cap.

• Slowly add unleaded regular gasoline to fuel tank. Be careful not to overfill.Allow about 1.5" of tank space for fuel expansion (Figure 2).

• Install fuel cap and wipe up any spilled gasoline.

IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts, such as the carburetor, fuel filter, fuel hose or tank during storage.Also, experience indicates that alcohol–blended fuels (called gasohol, ethanol or methanol) can attract moisture, which leads to separation and formation of acids during storage. Acidic fuel can damage the fuel system of an engine while in storage.

To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. See “Storage” on page 11. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

GROUNDING THE

GENERATOR

The National Electrical Code requires that the frame and external electrically conductive parts of this generator be properly connected to an approved earth ground. Local electrical codes may also require proper grounding of the unit. For that purpose, a GROUNDING WING NUT is provided on the generator end (Figure 3).

Generally, connecting a No. 12 AWG (American Wire Gauge) stranded copper wire to the grounding wing nut and to an earth–driven copper or brass grounding rod (electrode) provides adequate protection against electrical shock. Be careful to keep the grounding wire attached after connecting the stranded copper wire. However, local codes may vary widely. Consult with a local electrician for grounding requirements in your area.

Properly grounding the generator helps prevent electrical shock if a ground fault condition exists in the generator or in connected electrical devices. Proper grounding also helps dissipate static electricity, which often builds up in ungrounded devices.

OPERATING THE

GENERATOR

CAUTION! Never start or stop the engine with

electrical loads connected to the receptacles AND with the connected devices turned ON.

Starting the Engine

Disconnect all electrical loads from the generator. Use the following start instruction steps by numerical order:

1. Turn the fuel valve to the “On” position (Figure 4).

2. Place the choke lever in the “Choke” position

(Figure 5).

3. Set the rocker switch to “On” position (Figure 6).

4. Grasp the recoil handle and pull slowly until slight

resistance is felt.Then pull rapidly to start engine.

5. Move choke lever to “Run” position a short distance at

a time over several seconds in warm weather or minutes in cold weather. Let engine run smoothly before each change. Operate with choke in “Run” position.

NOTE: If engine still fails to start after 3 pulls, check for proper oil level in crankcase.This unit is equipped with a low oil device which prevents the engine from being started when the oil drops below a safe level in the crankcase. See engine manual.

Refer to the engine owner’s manual for more detailed starting instructions.

DON'T OVERLOAD YOUR

GENERATOR

Capacity

You must make sure your generator can supply enough rated (running) and surge (starting) watts for the items you will power at the same time. Follow these simple steps:

1. Select the items you will power at the same time.

2. Total the rated (running) watts of these items.This is

the amount of power your generator must produce to keep your items running. See Figure 9.

3. Estimate how many surge (starting) watts you will

need. Surge wattage is the short burst of power needed to start electric motor-driven tools or appliances such as a circular saw or refrigerator. Because not all motors start at the same time, total surge watts can be estimated by adding only the item(s) with the highest additional surge watts to the total rated watts from step 2.

Example:

Total Rated (Running) Watts = 3075 Highest Additional Surge Watts = 1800 Total Generator Output Required = 4875

Power Management

To prolong the life of your generator and attached devices, it is important to take care when adding electrical loads to your generator. There should be nothing connected to the generator outlets before starting it's engine.The correct and safe way to manage generator power is to sequentially add loads as follows:

1. With nothing connected to the generator, start the

engine as described in this manual.

2. Plug in and turn on the first load, preferably the largest

load you have.

3. Permit the generator output to stabilize (engine runs

smoothly and attached device operates properly.

4. Plug in and turn on the next load.

5. Again, permit the generator to stabilize.

6. Repeat steps 4 and 5 for each additional load. Never add more loads than the generator capacity.Take

special care to consider surge loads in generator capacity, as described above.

*Wattages listed are approximate only. Check tool or appliance for actual wattage.

GENERAL MAINTENANCE

RECOMMENDATIONS

The Owner/Operator is responsible for making sure that all periodic maintenance tasks are completed on a timely basis; that all discrepancies are corrected; and that the unit is kept clean and properly stored. Never operate a

damaged or defective generator.

Engine Maintenance

See engine owner’s manual for instructions. If you need service for your engine, you need to determine

the engine identification number.To do so, remove the rocker arm cover hood, item number 55 shown on page 16, by removing the four nuts and washers holding it in place.The engine model-type-trim number is stamped on the side of the inner cover attached to the engine. Have this number in hand when you call the engine service center for assistance.

CAUTION! Avoid prolonged or repeated skin

contact with used motor oil. Used motor oil has been shown to cause skin cancer in certain laboratory animals.Thoroughly wash exposed areas with soap and water. KEEP OUT OF REACH OF CHILDREN. DON'T POLLUTE. CONSERVE RESOURCES. RETURN USED OIL TO COLLECTION CENTERS.

Generator Maintenance

Generator maintenance consists of keeping the unit clean and dry. Operate and store the unit in a clean dry environment where it will not be exposed to excessive dust, dirt, moisture or any corrosive vapors. Cooling air slots in the generator must not become clogged with snow, leaves or any other foreign material.

NOTE: Do Not use a garden hose to clean generator. Water can enter engine fuel system and cause problems. In addition, if water enters generator through cooling air slots, some of the water will be retained in voids and cracks of the rotor and stator winding insulation.Water and dirt buildup on the generator internal windings will eventually decrease the insulation resistance of these windings.

To Clean the Generator

CAUTION! Never insert any object or tool

through the air cooling slots, even if the engine is not running.

• Use a damp cloth to wipe exterior surfaces clean.

• A soft bristle brush may be used to loosen caked on dirt or oil.

• A vacuum cleaner may be used to pick up loose dirt and debris.

• Low pressure air (not to exceed 25 psi) may be used to blow away dirt. Inspect cooling air slots and opening on generator.These openings must be kept clean and unobstructed.
