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.

NOTICE

Any attempt to crank or start the engine before it has been properly filled with the recommended oil will result in equipment failure.

Refer to Maintenance for oil fill information.

Damage to equipment resulting from failure to follow this instruction will void warranty.

Add Fuel

Fuel must meet these requirements:

Clean, fresh, unleaded gasoline.

A minimum of 87 octane/87 AKI (91 RON). High altitude use, see High Altitude.

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

NOTICE

Avoid generator damage.

Failure to follow Operator’s Manual for fuel recommendations voids warranty.

DO NOT use unapproved gasoline such as E85.

DO NOT mix oil in gasoline.

DO NOT modify engine to run on alternate fuels.

To protect the fuel system from gum formation, mix in a fuel stabilizer when adding fuel. See Storage. All fuel is not the same. If you experience starting or performance problems after using fuel, switch to a different fuel provider or change brands. This engine is certified to operate on gasoline. The emission control system for this engine is EM (Engine Modifications).

WARNING

Fuel and its vapors are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

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.

Fill fuel tank outdoors.

DO NOT overfill tank. Allow space for fuel expansion.

If fuel spills, wait until it evaporates before starting engine.

Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition sources.

DO NOT light a cigarette or smoke.

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

2.Slowly add unleaded gasoline (A) to fuel tank (B). Be careful not to overfill. Allow about 1.5" (4 cm) of tank space (C) for fuel expansion.

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

High Altitude

At altitudes over 5,000 feet (1524 meters), a minimum

85 octane / 85 AKI (89 RON) gasoline is acceptable. To remain emissions compliant, high altitude adjustment is required. Operation without this adjustment will cause decreased performance, increased fuel consumption, and increased emissions. See an authorized dealer for high altitude adjustment information. Operation of the engine at altitudes below 2,500 feet (762 meters) with the high altitude kit is not recommended.
