How to Fix / Troubleshooting
Safety First: If you smell raw gas, shut off the gas supply immediately, turn the generator OFF, and ventilate the area. Do not create sparks or flames. For gas leaks, contact a licensed gas technician.
- 1. Inspect gas connections (visual only): Look for damaged or kinked gas piping and flexible connectors. Do not tighten or loosen fittings unless qualified.
- 2. Check exhaust joints: After cooling, inspect the exhaust manifold, flex pipe, and muffler joints for soot or cracks. Tighten clamps and replace gaskets as needed.
- 3. Ensure exhaust outlet is clear: Remove any obstructions (snow, leaves) from the exhaust outlet to prevent fumes from backing up.
- 4. If fuel leak is suspected: Leave the gas supply OFF and arrange for professional repair before restarting.
