A portable generator is a vital tool during emergencies, but it needs to be properly maintained to ensure it’s ready when you need it. Here’s a detailed guide on keeping your generator in peak condition and using it safely.

1. Keep the Tank Empty & Store Fresh Fuel

• Empty the Tank: Run your gas generator until it stops to avoid fuel degradation, which can clog fuel lines and engines.
• Store Fresh Fuel: Use ASTM-approved canisters for gasoline and add a fuel stabilizer. Rotate the fuel by using old gas in your car and refilling with fresh gas.
• Why Not Stabilizer in the Generator? Stabilizer helps keep fuel fresh, but after 6–12 months, you’ll need to replace it. It’s easier to manage fresh fuel in a gas can than in the generator itself.

2. Perform Regular Test Runs

• Run Twice a Year: Start the generator periodically to check for issues and familiarize yourself with its operation.
• Test New Generators: Always run a new generator to ensure it functions correctly before an emergency.
• How Long to Run? For gas models, run it on about a pint of gas until it shuts off. For propane models, a full shutoff isn’t necessary since propane doesn’t leave residue.

3. Replace or Clean Parts

• Check for Issues: Look for clogged air intakes, fouled spark plugs, or gummed-up filters and carburetors.
• Inspect Oil Levels: Keep the engine oil at the proper level, adding as needed.
• Get Repairs Quickly: If problems persist, contact the manufacturer (if under warranty) or a repair shop.

4. Keep Enough Fuel on Hand

• Stock Up: Have at least 10 gallons of gasoline or two 20-pound propane tanks ready.
• Run Times:
  | Generator Capacity (Watts) | 10-Gallon Run Time (Avg.) |
  |------------------------------|-----------------------------|
  | <1,500 | 62 hours |
  | 1,500–2,500 | 43 hours |
  | 2,500–5,000 | 24 hours |
  | 5,000–7,000 | 13 hours |
  | 7,000–8,500 | 12 hours |

5. Recharge Generator Batteries Regularly

• Recharge Every 3 Months: Plug in battery-powered starters for 24 hours to ensure they’re fully charged.
• Portable Power Stations: Recharge these battery-powered units regularly, as they may drain faster during storage.

6. Store Your Generator and Fuel Safely

• Store Generators in a Dry Place: Keep them in a clean, ventilated location, ideally detached from your home.
• Avoid Sparks and Flames: Keep fuel and generators away from water heaters, furnaces, or anything that could ignite fumes.
• Consider Protective Covers: Use insulated covers for generators stored in extreme climates or invest in a dedicated enclosure.

7. Focus on Carbon Monoxide (CO) Safety

• CO Sensors: Opt for generators with built-in CO safety shutoff features. These models are safer and automatically stop operating if CO levels rise.
• Proper Placement: Always run the generator at least 20 feet from your home, with exhaust pointed away from windows and doors.
• CO Danger: Never run a generator indoors, in a garage (even with doors open), or on an attached porch.

8. Use a Transfer Switch for Efficiency

• Why Use a Transfer Switch? It simplifies powering your home’s circuits during outages and eliminates the need for multiple extension cords.
• Professional Installation: Hire an electrician to install the switch, allowing you to use outlets and appliances as usual.

Pro Tips for Long-Term Reliability

• Check Your Generator Before Storms: Avoid last-minute surprises by ensuring your unit works ahead of severe weather.
• Choose Generators Wisely: Consider models tested and rated for CO safety, emissions, and reliability in Experts' Generator Ratings.

By following these steps, you can ensure your portable generator is ready to provide power when it matters most. Stay prepared and stay safe!
