Tips to Safely Maintain Your Generator During a Storm

A properly maintained generator helps keep your home powered safely during outages—especially in severe weather. Follow these important tips to protect your equipment, your home, and your family.

General Generator Maintenance Tips

• Schedule annual professional maintenance to ensure reliable performance
• Run your generator periodically to keep internal components lubricated
• Keep the area around the generator clear of debris, leaves, and vegetation
• Replace air and fuel filters as recommended
• Pay attention to warning lights or alerts and address them promptly
• Keep records of service and maintenance

Steps to Check Generator Oil During a Storm

1. Safety First
Never check the oil while the generator is running or extremely hot.

2. Shutdown Procedure
Turn off the main circuit breaker (often located on the generator or in the transfer switch) to stop power to the home.

3. Cool Down
Allow the generator to rest for 10–15 minutes so the oil can settle and provide an accurate reading.

4. Check the Oil Level
Locate the dipstick, remove it, and wipe it clean.

5. Reinsert and Read
Reinsert the dipstick fully, then remove it again. The oil level should be between the MIN and MAX marks.

6. Add Oil if Needed
If the level is low, add the recommended oil (typically 5W-30 synthetic) in small, slow increments to prevent overfilling.

7. Restart the System
Once the oil level is correct, return the controller to “Auto” or restart the generator, then re-engage the circuit breaker.

Important: During extended outages, check oil levels every 12 hours of continuous run time to help prevent engine damage.

After a Snow Event: Clear Exhaust & Vents ❄️

After snowfall or ice buildup:

• Regularly shovel snow and remove ice from around the generator
• Maintain at least 2–3 feet of clearance on all sides
• Ensure the exhaust and vents are never blocked

Blocked airflow can cause overheating and lead to dangerous carbon monoxide buildup.

Also, be sure to keep a clear, safe path shoveled to the generator so technicians can access it if needed—and so you can safely check oil during a storm.
