The generator shuts down after running for a while, and the enclosure feels very hot.

Safety first: Turn OFF the generator and allow it to cool completely. Disconnect the battery negative terminal before cleaning.

• Clearances: Ensure at least the minimum clearance specified by DuroMax (often 3–5 feet) around all sides of the enclosure.
• Clean vents: Remove leaves, dust, and debris from intake and exhaust louvers.
• Cooling fan: Verify that the engine cooling fan operates and that belts (if used) are intact and properly tensioned.
• Clean fins: Use compressed air to blow dust and debris off cylinder and alternator fins.
