15 May Generator Maintenance Tips: How to Keep Your Backup Power Source Ready

Ensure Your Generator is Always Ready with These Essential Maintenance Tips

Regular Inspection and Testing

Regular inspections and testing are vital to keep your generator in top shape. Schedule a monthly check to spot any visible issues like frayed wires, corrosion, or leaks. Pay attention to the generator’s exterior, making sure there are no obstructions affecting ventilation. Testing your generator under load conditions for about 30 minutes helps to identify potential problems. This process also keeps the battery charged and ensures the generator starts and runs correctly. Listen for unusual noises or vibrations that might indicate a problem. Marra Electric advises keeping a maintenance log to track your inspections and tests, noting any issues and actions taken. This log will help you stay on top of maintenance tasks and provide useful information for professional servicing.

Keep the Fuel System Clean

Maintaining a clean fuel system is crucial for your generator’s performance. Fuel can get contaminated with debris, water, and other impurities over time, leading to clogs and engine issues. Check the fuel filters regularly and replace them when necessary to prevent these problems. Using a fuel stabilizer can help if your generator isn’t used often, as it prevents fuel from degrading. Store fuel in a clean, dry place away from extreme temperatures to maintain its quality. Marra Electric recommends draining the fuel tank periodically to remove any sediment or water that has accumulated. Always use fresh, clean fuel when refueling to reduce the risk of contamination. Proper fuel maintenance keeps your generator running smoothly and extends its lifespan.

Check and Change the Oil

Oil is essential for lubricating your generator’s moving parts and reducing friction. Regularly checking and changing the oil is vital for maintaining your generator’s health. Refer to your generator’s manual for the recommended oil type and change intervals, typically every 50 to 100 hours of operation or at least once a year. When checking the oil, make sure the generator is on a level surface and the engine is cool. Remove the dipstick, wipe it clean, reinsert it, then check the oil level and color. The oil should be clear and amber-colored. If it’s dark or gritty, it’s time for a change. 

Marra Electric recommends inspecting and replacing the oil filter during each oil change to keep the oil clean. Keeping up with oil maintenance helps prevent engine wear and overheating, ensuring your generator is ready when you need it most.

Battery Maintenance

The battery is crucial for starting your generator. Regular battery maintenance ensures it remains reliable. Start by checking the battery terminals for corrosion and clean them with a mixture of baking soda and water if needed. Ensure the battery is fully charged and test its voltage with a multimeter. If the voltage is below the manufacturer’s recommended level, recharge or replace the battery. Inspect the battery case for any cracks or leaks, and ensure the cables are secure and undamaged. Marra Electric advises storing batteries in a cool, dry place and checking them monthly to maintain their charge. 

In cold climates, using a battery warmer can prevent freezing. Proper battery care ensures your generator starts promptly in an emergency, providing peace of mind that your backup power source will be ready when needed.

Air Filter Maintenance

Air filters keep dirt and debris out of your generator’s engine, ensuring it runs smoothly. Over time, these filters can get clogged, reducing airflow and efficiency. Check the air filter regularly and clean or replace it as needed. For most generators, cleaning involves removing the filter and gently tapping it to dislodge dirt. If the filter is heavily soiled or damaged, replace it with a new one. Marra Electric recommends following the manufacturer’s guidelines for air filter maintenance. 

Additionally, inspect the air intake system for any blockages or damage that could affect the filter’s performance. Keeping the air filter and intake system clean not only improves the generator’s efficiency but also prevents engine damage. Regular air filter maintenance is a simple yet effective way to ensure your generator remains reliable and efficient.

Professional Maintenance and Servicing

While regular DIY maintenance is essential, professional servicing ensures your generator remains in top condition. Schedule an annual inspection and servicing with a qualified technician to address any complex issues and perform thorough checks. Professional maintenance includes inspecting and adjusting the engine, checking electrical connections, and ensuring all components are functioning correctly. Technicians can also perform load bank testing to simulate real-world conditions and ensure your generator operates at its peak performance.
