Generator is leaking engine oil onto the base pan or ground; no code displayed.

Safety first: Turn OFF the generator and allow the engine to cool. Oil may be hot.

• Locate leak: Clean the engine exterior and base pan, then run briefly and inspect for fresh oil trails.
• Check oil filter: Ensure the Hyundai Power oil filter is hand-tight plus a small additional turn. Replace the filter and gasket if leaking at the seal.
• Inspect drain plug: Verify that the oil drain plug is tight and that its gasket is intact. Replace the gasket if seeping.
• Examine seals and hoses: Look at the front and rear crankshaft seals and any oil cooler lines for wetness. Replace leaking hoses; seal replacement typically requires professional service.
• Refill and test: Top up oil to the correct level and monitor for further leakage.
