How to Store Your Generator Safely

Last updated on November 6, 2019 at 11:31 am

Prior to and during the widespread power outages caused by Hurricane Sandy, many New Jersey residents became first-time owners of portable generators. Many new owners may not realize that safely storing your generator is just as important as taking precautions while using it. After all, you want to be sure that your generator will start the next time you need it. Here are some tips for how to store your generator safely.

• For long-term storage it’s typically recommended to store your generator without any gasoline in it. If you do not wish to run the generator until it is empty for the sake of burning fuel, you could transfer the gas to your automobile. Most generators use the same type of fuel (regular, unleaded) as cars. Drain your generator according to directions in your owner’s manual.

• Although removing the gas is highly recommended, you can store the generator with the gas inside if you use a stabilizer to prevent corrosion. If you choose to store the generator with the gas inside, it is best to leave the gas tank full and refer to the manufacturer’s instructions for more details about your specific model.

• If you are storing gasoline separately, use an approved gas container and keep it in a well ventilated area away from the house in either a shed or unattached garage. Gasoline will stay longer if stored in a cool, dry place and kept around 95% full with a commercial stabilizer added.

According to the website of generator manufacturer Briggs & Stratton, before storing the generator, it is important to thoroughly clean the interior and exterior.

  • Clean the generator looking around and underneath for signs of oil or fuel leaks.
  • Clean any accumulated debris from inside and outside the generator, making sure the linkage, spring, and other engine controls are clean.
  • Check that the area around and behind the muffler is free from any combustible debris.
  • Inspect cooling air slots and openings—these areas must be clean and unobstructed.
  • Before storing your generator, take it for a tune-up to ensure it is ready for use if/when you may need it. Most local lawn mower repair stores are able to provide this service.

Properly storing your generator will help keep it ready for the next time you need it. Plymouth Rock Assurance also has tips to help you prepare to handle a variety of severe weather.

  1. Changing the oil is also importatant
    Best to change when warm
    Should be done once a year, or after 25 hours of operation.

  2. Thank you for this information. We purchased a generator but never had to use it. It is full of fuel and we need to purchase the stabilizer you speak of. We were blessed. We live near a creek and when the tide became full during the storm. It was just two feet from our back porch. God bless all those who were affected and need your assistance. May you all be safe out there until the last home is back to normal.

  3. Thanks for clearing up my question about storing gas inside the generator. But even after reading this, I still won’t store gas inside it. I might only use it from time to time but I won’t store gas in it.

  4. I would think the gas line (rubber) would crack in a Florida hot garage with out gas in it.
    What do you think?


  5. I like your suggestion about having your generator for a tune-up before storing it to ensure it is ready for use when you may need it. It’s rare that we encounter power interruptions in our area so we usually have the generator stored. It’s important to me that the generator will function in times of emergency, so I’ll be sure to have it serviced before storage.

  6. I am using a Rubbermaid yard storage with doors and split top. Will hold my Champion 3100 Inverter dual fuel generator and the propane tank safely. Rosemarie – I wouldn’t store it in the van unless you have drained all the gas – with the cap on I would think it’s safe. Better yet how about one of the hitch cargo carrier that would hold it outside and cover it.
