Why You Should Exercise Your Standby Generator (Even If There's No Power Outage)
Beginners, take note: Just because it’s not in use doesn’t mean it doesn’t need love!
Many people believe that a standby generator only needs attention when the lights go out… but that’s a big mistake!
Exercising your standby generator means running it regularly—without load or under light load—for a short period (typically 15–30 minutes). And here’s why it matters:
5 Reasons to Exercise Your Generator Weekly or Monthly:
1. Keeps Engine Parts Lubricated
Just like your car, a generator sitting too long can suffer from dried seals and stiff components. Running it helps circulate oil to keep things moving smoothly.
2. Maintains Battery Health
Generators rely on battery power to start. Regular exercise ensures the battery stays charged and ready—especially in cold or humid climates.
3. Prevents Fuel System Clogs
Diesel can degrade and gum up filters and injectors if unused. Running the engine helps burn off stale fuel and flush the system.
4. Lets You Detect Early Problems
By listening, smelling, or feeling for anything unusual (smoke, noise, vibration), you can spot issues before they become disasters.
5. Verifies System Readiness
Running your generator regularly confirms it will actually work when the grid fails. Peace of mind is priceless!
Tips for Exercising Your Generator:
Schedule it weekly or at least monthly.
Run it for 15–30 minutes.
Make sure there’s no warning light or unusual noise.
Preferably run it with a light load to simulate real use.
Beginner Takeaway:
A standby generator is like a fire extinguisher—you hope you never need it, but when you do, it must work.
Regular exercise is the secret to making sure it’s always ready.
