As fall arrives, you might not think about your generator, but a maintenance check is essential for its performance during the colder months. Start by inspecting fuel levels and ensuring oil quality, because even a small oversight here can lead to big issues down the line. You'll also want to check the battery, air filters and electrical connections.

Inspect Fuel Levels

Check the fuel levels in your generator to ensure it's ready for the fall season. Low fuel can lead to issues when you need your generator the most. As you inspect, keep an eye out for fuel contamination risks, which can arise from water or debris in the tank. Contaminated fuel can cause your generator to run inefficiently or not at all.

To mitigate these risks, consider using fuel stabilization methods. These additives can help prolong the life of your fuel by preventing degradation and separating water. Adding a stabilizer when you fill up can save you headaches down the line.

Proper storage techniques are just as crucial. If you plan on storing fuel for an extended period, make sure to use clean, approved containers and keep them in a cool, dry place. Avoid exposing your fuel to sunlight, as heat can lead to evaporation and further contamination.

Start by checking the oil level and its appearance. If the oil looks dark or gritty, it's likely time for an oil change. Generally, you should follow the recommended oil change frequency in your generator's manual, which is typically every 50 to 100 hours of use.

Next, don't overlook the oil filter's importance. A clean oil filter ensures that contaminants don't circulate through your generator's engine, enhancing its performance and longevity. If you haven't changed the oil filter recently, do it alongside the oil change.

Consider using synthetic oil for your generator. Synthetic oil offers better stability at varying temperatures and provides superior protection against wear and tear, which can prolong your generator's life. It's ideal for those who use their generators frequently or in extreme conditions.

Test Battery Performance

It's essential to test your generator's battery performance to ensure reliable operation when you need it most. Start by checking the battery's condition; look for any signs of corrosion or loose connections. A well-maintained battery can significantly extend its lifespan, so regular inspections are key.

Next, perform load testing to evaluate the battery's ability to hold a charge. This process simulates the generator's operating conditions and helps identify any weaknesses. If your battery struggles under load, it may be time for a replacement.

Also consider maintenance frequency. Depending on your generator's usage, testing the battery every three to six months can be beneficial. However, during peak seasons or heavy usage, more frequent checks are recommended.

Finally, keep track of the battery's age; most batteries last between three and five years. If your battery's nearing the end of its lifespan, plan for a replacement to avoid unexpected failures. By regularly testing your generator's battery performance, you ensure it's ready to power your home when emergencies arise.

Examine Air Filters

Review Electrical Connections

Some generator maintenance tasks can be completed on your own. But many require the help of an experienced, certified generator repair expert. Electrical connections typically fall in the category of "expert needed." If you would like help with your generator as we near fall, give us a call at 720-589-2338.


Regularly reviewing your generator's electrical connections ensures a reliable power supply and prevents potential malfunctions. Start by inspecting all visible wiring for signs of wear, fraying, or corrosion. These issues can compromise connection integrity and lead to serious problems down the line.

Next, check all terminals and connectors for tightness. Loose connections can cause overheating and impact your generator's performance. Make sure to clean any corrosion using a wire brush and apply a protective lubricant to enhance electrical safety.

Don't forget to inspect the grounding connections as well. A solid ground is crucial for both safety and functionality. If you're unsure about the condition of any connections, consider consulting a professional for a thorough inspection.

Finally, establish a maintenance frequency that suits your generator's usage. Regularly scheduled checks can help catch potential issues before they escalate. By incorporating these practices into your maintenance routine, you'll not only extend the life of your generator but also ensure it runs efficiently when you need it the most.

Conclusion

By following this fall generator maintenance checklist, you can ensure your generator runs smoothly when you need it most. Regularly inspecting fuel levels, oil quality, battery performance, air filters, and electrical connections will not only enhance efficiency but also extend the life of your equipment. Don't wait until winter hits—take the time now to perform these checks. Staying proactive means you'll be prepared for any power outages and can enjoy peace of mind all season long.
