Generators are an essential piece of equipment for many homeowners and businesses. They provide backup power during a power outage, keep construction sites running, and power up outdoor events. 

However, maintaining your generator is crucial to ensure its optimal performance and longevity. Here are five generator care do’s and don’ts you should know about.

1. DO Regular Maintenance Checks

Like any other piece of machinery, generators need regular maintenance checks to ensure they are running smoothly. Check the oil level and change it regularly. 

Make sure the air filter is clean and replace it if necessary. Inspect the fuel filter and replace it if it’s dirty. You should also check the spark plug and replace it if it’s worn out. Regular maintenance checks will ensure your generator is always ready to go when you need it.

2. DO Keep the Generator Clean and Dry

Generators should be kept clean and dry at all times. Dirt and debris can clog the air filter and cause the generator to overheat. Use a soft cloth to wipe down the exterior of the generator and remove any dirt or debris. If your generator is stored outside, make sure it is covered to protect it from the elements.

Moisture can also cause damage to the generator’s electrical components, leading to corrosion and other issues. This is especially important for those who live in areas with high humidity or frequent rain. Regularly wiping down the exterior of the generator with a soft cloth, and ensuring it is stored in a dry place will help prevent any moisture buildup. 

3. DO Store Fuel Properly

Gasoline and diesel fuel are both highly flammable and dangerous if not handled properly. Store fuel in a cool, dry, and well-ventilated area away from any heat sources or open flames. Use a fuel stabilizer to keep the fuel fresh and prevent it from breaking down over time. Check the manufacturer’s instructions for proper fuel storage guidelines.

4. DON’T Neglect to Check the Battery

The battery is a critical component of your generator. Neglecting to check the battery regularly can result in it losing its charge or failing altogether. Check the battery every month and replace it if it’s not holding a charge.

Without a functional battery, the generator won’t be able to start up when needed, rendering it useless during a power outage or emergency situation. Regular maintenance and repair will ensure that the generator is always ready to provide backup power.

5. DON’T Forget to Shut Off the Fuel Valve

Leaving the fuel valve open when the generator is not in use can result in fuel leaking. When you’re finished using your generator, don’t forget to shut off the fuel valve. This will prevent fuel from leaking and causing a fire hazard. 

It will also help prevent any fuel from going bad if it’s left in the generator for an extended period. Fuel left in the generator for an extended period can cause issues when trying to start the generator in the future. 


Following these generator care do’s and don’ts will help ensure your generator is always ready to provide backup power. Regular maintenance checks are essential to keeping it in good condition. By following these guidelines, you can extend the lifespan of your generator and keep it running smoothly for years to come.
