• Add oil slowly until it reaches the upper mark on the dipstick. Do not overfill.
• The generator features a low oil shutdown system to protect the engine.

4.3 Adding Fuel

The GKJ11000ED operates on either gasoline or propane.

For Gasoline Operation:

• Ensure the generator is turned off and cooled down before adding fuel.
• Use fresh, unleaded gasoline with an octane rating of 87 or higher.
• The gasoline fuel tank capacity is 6.6 gallons.
• Do not fill the tank completely; leave space for fuel expansion.
• Securely close the fuel cap after filling.

For Propane (LPG) Operation:

• Connect a standard propane tank (not included) to the generator's LPG inlet using the appropriate hose and regulator (ensure hose is tightly secured).
• Ensure all connections are tight to prevent leaks.
