Generator enclosure panels rattle or vibrate loudly during operation.

Safety first: Turn controller to OFF and wait for engine to stop before tightening panels.

• Tighten hardware: Inspect all panel screws and latches. Tighten or replace missing fasteners with Briggs & Stratton-approved hardware.
• Panel fit: Adjust panel alignment so edges seat properly against gaskets.
• Gasket condition: Replace flattened or missing panel gaskets to reduce vibration and noise.
• Leveling: Ensure the generator base is level and fully supported on the pad.
