10. Return generator to normal operating position (resting on wheels and support leg).

Verify Engine Oil Level

The generator engine is shipped from the factory filled with oil (API SJ or higher 10W-30). This allows for generator operation in the widest range of temperature and climate conditions. Before starting the engine, check oil level and ensure that engine is serviced as described in Maintenance.

NOTE: See Oil in the Maintenance section to review oil recomendations. Verify provided oil in engine is the correct viscosity for current ambient temperature.

Add Fuel

All fuel is not the same. If a starting or performance problem is encountered immediately after new fuel has been used, try another service station or change brands.

NOTE: This engine is certified to operate on gasoline. Exhaust Emissions Control System: EM (Engine Modifications).

Type of Fuel

1. Always use clean, fresh, unleaded gasoline with a minimum of 87 octane/87 AKI (91 RON) with equipment. DO NOT mix oil with fuel. DO NOT modify the engine fuel system or carburetor to run on alternative fuels.

NOTE: Fuel with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether) is acceptable.

IMPORTANT: Use of any fuel other than those approved above will void warranty. Some areas require that fuel pumps be marked if the fuel contains alcohols or ethers. If you are not sure if your fuel contains alcohol or ethers that are different than those approved above, then check with the service station operator.

2. Clean area around fuel fill cap, remove cap.

3. Slowly add unleaded gasoline (A) to fuel tank (B). Be careful not to overfill. Allow at least 1.5" (38 mm) of tank space (C) for fuel expansion, as shown in Figure 2.

4. Install fuel cap and let any spilled fuel evaporate before starting engine.

To avoid engine problems, the fuel system should be treated with a fuel preserver or emptied before storage of 30 days or longer. To protect the fuel system from gum formation, use Briggs & Stratton FRESH START™ fuel stabilizer plus. If fuel preserver is not used, drain the fuel tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. See Storage in the Maintenance section for additional information.

NEVER use engine or carburetor cleaner products in the fuel tank as permanent damage may occur.

High-altitude use

Operation at high altitudes (over 5,000 feet [1524 m]), may require a high-altitude carburetor jet kit to improve performance and decrease fuel consumption. See your local authorized Briggs & Stratton dealer for more information.

When adding fuel:

• Turn generator OFF and let it cool at least 2 minutes before removing fuel cap. Loosen cap slowly to relieve pressure in tank.

WARNING

Don’t Overload 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 10.

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 its 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.

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 water or other liquids to clean generator. Liquids can enter engine fuel system, causing poor performance and/or failure to occur. In addition, if liquid enters generator through cooling air slots, some of the liquid will be retained in voids and cracks of the rotor and stator winding insulation. Liquid and dirt buildup on the generator internal windings will eventually decrease the insulation resistance of these windings.

Cleaning

Daily or before use, look around and underneath the generator for signs of oil or fuel leaks. Clean accumulated debris from inside and outside the generator. Keep the linkage, spring and other engine controls clean. Keep the area around and behind the muffler free from any combustible debris. Inspect cooling air slots and openings on generator. These openings must be kept clean and unobstructed.

Engine parts should be kept clean to reduce the risk of overheating and ignition of accumulated debris:

• Use a damp cloth to wipe exterior surfaces clean.

• Use a soft bristle brush to loosen caked on dirt or oil.

• Use a vacuum cleaner to pick up loose dirt and debris.

Oil

Oil Recommendations NOTE: When adding oil to the engine crankcase, use only

high quality detergent oil classified “For Service SF, SG, SH, SJ” or higher. DO NOT use special additives.

1. Choose a viscosity according to the following table:

* Check oil level frequently at higher temperatures.

NOTE: Synthetic oil meeting ILSAC GF-2, API certification mark and API service symbol with “SJ/CF ENERGY CONSERVING” or higher, is an acceptable oil at all temperatures. Use of synthetic oil does not alter required oil change intervals.

When adjusting or making repairs to your generator:

• Disconnect the spark plug wire from the spark plug and place the wire where it cannot contact spark plug.

When testing for engine spark:

• Use approved spark plug tester.

• DO NOT check for spark with spark plug removed.

Unintentional sparking can result in fire or electric shock.

WARNING

• DO NOT expose generator to excessive moisture, dust, dirt, or corrosive vapors.

• DO NOT insert any objects through cooling slots.

Improper treatment of generator can damage it and shorten its life.
