5 Tips for Portable Generator Maintenance

Many are already familiar with the handiness and versatility of a portable generator. However, it is important to ensure that this versatility and power remain readily available when needed. 

Maintenance is vital to owning a portable generator. Failing to properly maintain the unit can lead to hard starting and inefficiency. Following these five portable generator maintenance tips will help ensure that a backup power source stays reliable. 

Fresh Oil Helps 

As with any small-engine power equipment, changing the oil is a major factor in maintaining reliability. Most new generators require the first oil change after just 30 hours of use. Once the initial oil change is completed, future oil changes only need to be performed every 100 hours of use, or at least once per season. To remain prepared for unexpected, extended power outages, it is wise to stock up on oil, oil filters, and gasoline.

Plugs & Filters 

Without a way to breathe and a way to ignite the gas in the engine cylinders, a generator would be useless. The spark plug and air filter should be changed after every 200 hours of use, or at least once at the start of each season. Pairing a new spark plug with a clean air filter will ensure a proper fuel-air mixture, helping the engine run more efficiently and extending the lifespan of the generator. 

Store it on an Empty Tank 

If a generator is being put into storage for longer than a month, the fuel should be drained from the tank. This process begins by adding a quality gas stabilizer to the fuel in the tank and running the unit for about 15 minutes. After the engine cools down, it should be started and run again until it runs out of gas and shuts down. If a significant amount of gasoline remains in the tank, a siphon may be used. It is important to ensure that the siphon is non-conductive to avoid generating static electricity in the tank. 

Change the Battery 

Not all portable generators include a battery, but those featuring an electric start should be fully charged before storage. If possible, the battery should be plugged into a trickle charger to keep it fresh and ready for use. 

Train in the Offseason 

While storage tips make a significant difference, it is always best to start a generator every 30 days and allow it to run for a few minutes. Doing so helps keep components lubricated by circulating the oil throughout the engine.
