Standby Generator Maintenance

How to Maintain a Home Standby Generator

By  | Generator Product Expert

Just like any other engine-powered machine, standby generators require regular maintenance.

Just like your car needs an oil change every 3 months or 3,000 miles, most standby generators need one every 2 years or after 200 hours of use.

The generator keeps itself in shape throughout the year with weekly low-speed exercise cycles.

A maintenance kit comes with everything you need to make sure your generator passes its yearly physical.

Owner's Manual
An important rule of thumb, and one we can't stress enough, is to read your owner's manual. It contains model-specific information that will allow the best operation and performance from your generator.

To perform an oil change on your standby, empty the old oil and replace it with 2 quarts of new oil. You'll also need to replace your old, dirty oil filter.

If your generator runs for an extended time, after 48 hours allow it to cool down. It's a lot of heat for an air-cooled engine so you'll want to check the oil and change it if needed.

You can choose either regular, or synthetic oil. Synthetic oil is designed for superior high- and low-temperature viscosity, meaning it will perform better for cold starts or while running in extreme heat.

Spark Plugs

Install the new spark plugs to keep your generator running in top form.

Air Filter

So take out the old air filter. Slap in the new one. And like that, your home standby generator will be ready for your next power outage.
