Generator is excessively loud or has a sharp exhaust bark compared to normal operation.

Safety first: Turn the generator OFF and allow the exhaust system to cool completely. Exhaust components can cause severe burns.

• Inspect exhaust joints: Check the connection between the engine exhaust manifold, muffler, and exhaust piping for soot marks or visible gaps indicating leaks.
• Tighten fasteners: Carefully tighten loose exhaust flange nuts or clamps. Do not overtighten to the point of stripping threads.
• Replace damaged parts: If the muffler or pipe is cracked or rusted through, replace it with a Ryobi‑approved exhaust component.
• Check mounting brackets: Ensure exhaust hangers and brackets are intact to prevent vibration‑induced damage.
