Buffalo Generator Maintenance

Regular maintenance ensures your whole-home generator operates reliably when needed. Without proper upkeep, generators can develop issues like fuel system clogs, battery failure, or electrical malfunctions. Routine servicing helps extend the generator’s lifespan and prevents unexpected breakdowns during power outages.

Most manufacturers recommend professional maintenance at least once a year, but more frequent checks may be needed if the generator runs often. Monthly self-checks, such as running the unit and inspecting for leaks or damage, can help ensure readiness. An annual tune-up by a professional technician ensures optimal performance.

A generator maintenance service includes checking the oil, replacing air and fuel filters, testing the battery, and inspecting electrical connections. The technician will also run the generator under load to ensure it operates correctly. Any worn or faulty components will be repaired or replaced to prevent failures.

Oil changes are typically required after every 50-100 hours of operation or at least once a year, depending on the model. If your generator runs frequently, such as during long power outages, oil changes may be needed more often. Clean oil helps keep the engine running smoothly and prevents excessive wear.

Most whole-home generators have an automatic self-test feature that runs the unit periodically. You can also manually test it by simulating a power outage and ensuring the generator activates properly. Checking for smooth operation and unusual noises can help catch potential issues before they become serious problems.

Common issues include dead batteries, clogged fuel lines, dirty filters, and worn-out spark plugs. Failure to start, excessive smoke, or unusual noises can indicate mechanical problems. Regular maintenance prevents these issues and ensures the generator is ready when needed.

Basic tasks like checking the oil, cleaning the air filter, and running the generator for short test periods can be done by homeowners. However, major servicing, electrical checks, and fuel system maintenance should be handled by a professional. Regular expert inspections help ensure safety and compliance with warranty requirements.

If your generator fails to start, runs erratically, or has visible damage, it’s best to call a professional. Annual inspections, tune-ups, and post-outage checkups should also be performed by a qualified technician. A professional ensures your generator is in top condition and ready for emergencies.
