5. Setup
Before starting the generator, perform the following setup steps:
- Unpacking: Carefully remove the generator and all accessories from the packaging. Inspect for any shipping damage.
- Add Engine Oil: The generator is shipped without engine oil. Place the generator on a level surface. Remove the oil fill cap/dipstick. Using the provided funnel, slowly add the recommended engine oil (e.g., 10W-30, refer to specifications for exact type and capacity) until it reaches the upper mark on the dipstick. Do not overfill.
- Add Fuel: Ensure the generator is off and cool. Open the fuel cap and carefully pour fresh, unleaded gasoline into the fuel tank. Do not overfill; leave space for fuel expansion. Securely close the fuel cap.
- Positioning: Place the generator on a firm, level surface outdoors, in a well-ventilated area, at least 20 feet away from any buildings, vehicles, or combustible materials. Ensure the exhaust is directed away from people and structures.
- Grounding: Connect a grounding wire from the generator's grounding terminal to an appropriate ground source, as per local electrical codes.
