10 Tips For Operating A Standby Generator

By John Karbowski · January 18, 2025

Standby generators provide reliable backup power during outages, ensuring your home or business stays operational. However, to get the most out of your generator and keep it running safely, proper operation and maintenance are essential. Here are 10 expert tips for operating your standby generator.

01

Perform Regular Test Runs

Run your generator under load at least once a month for 20–30 minutes. Regular exercise keeps the engine lubricated, the battery charged, and ensures the generator will start when you need it most.

02

Check Oil and Fluid Levels

Before each use and as part of regular maintenance, check engine oil, coolant, and fuel levels. Low oil levels can cause engine damage and void warranties.

03

Keep the Fuel Supply Fresh

If your generator uses gasoline or diesel, treat the fuel with a stabilizer to prevent degradation. Old or contaminated fuel is a leading cause of generator failures.

04

Inspect Air Filters Regularly

A clogged air filter reduces generator efficiency and can cause overheating. Clean or replace air filters according to the manufacturer's recommended schedule.

05

Monitor Load Carefully

Avoid overloading your generator by calculating your total power requirements before connecting equipment. Overloading can damage both the generator and your connected devices.

06

Ensure Proper Ventilation

Standby generators produce carbon monoxide. Always ensure adequate ventilation around your generator and never operate it in enclosed spaces.

07

Inspect Electrical Connections

Regularly inspect wiring, connections, and transfer switches for signs of wear, corrosion, or damage. Loose connections can cause arcing and fire hazards.

08

Test the Transfer Switch

The automatic transfer switch (ATS) is critical to your generator's operation. Test it periodically to ensure it activates properly during a power outage.

09

Schedule Professional Maintenance

Have a licensed electrician perform a professional inspection at least once a year. They can identify issues that may not be apparent during routine checks.

10

Keep Maintenance Records

Document all maintenance activities, test runs, repairs, and fuel consumption. Good records help identify trends and ensure your generator stays in optimal condition.
