Putting a portable generator away so it starts on the first pull next time — fuel, battery, storage spot, and the spring wake-up. Rather have a hand deciding? My number is (330) 200-8042.
Storing a Generator, at a Glance
A generator that sat all winter with untreated fuel is the single most common reason one won't start when an outage finally hits. This guide walks through the two right ways to handle the fuel, where and how to store it safely, tending the battery, and a simple checklist for waking it back up in spring. There's a printable 29-page version up top.
Common Questions
1 What's the biggest mistake people make storing a generator?
Leaving the fuel untreated. Stale fuel is by far the most common reason a stored generator won't start months later — stabilize it or run the carburetor dry before it goes away.
2 Should I stabilize the fuel or run the tank dry?
Either works well when done properly — check your owner's manual for its recommendation. Stabilizing is simpler; running it dry leaves nothing in the carburetor to gum up over a long storage stretch.
3 Where's the right place to store it?
Somewhere cool, dry, and ventilated — a garage or shed is fine — and always away from living space and anything with a flame or pilot light.
4 Does the battery need attention if it just sits?
Yes. A battery left alone for months often loses its charge or is damaged. A small battery tender keeps it topped off and ready for spring.
5 Can I store it in my basement?
No — keep it out of any living space, even while it's off, because of fuel fumes and fire safety. A detached garage or shed is the right spot.
6 How do I know it's really ready in spring?
Work through a proper wake-up checklist — oil, fuel, battery, a look-over for pests — then start it outdoors and run it under some load, not just a quick idle.
Would You Rather I Just Help?
Two short visits a year — put-away and spring wake-up — keep a generator reliable for years. I'll handle the fuel, the cleaning, and the checks, with nothing to sell you. $99 flat for a visit, 30-day come-back-free.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
