Generator Maintenance for Safety, at a Glance

Maintenance keeps a generator safe as well as reliable. A neglected one can catch fire from spilled or stale fuel, shock you through a damaged cord, or simply fail to start when the power's out. The habits are simple: check the oil before every use, keep fuel fresh and stored safely, never refuel a hot engine, inspect the cords, keep the vents clear, and test your CO alarms. And it always runs outdoors, at least 20 feet away. There's a printable page-by-page version up top.

Common Questions

1 Why does generator maintenance count as safety, not just longevity?

Because a neglected generator can be a real hazard, not only an unreliable one. Spilled or stale fuel and refueling a hot engine are fire risks, a cracked or overheated cord is a shock and fire risk, and low oil or old gas can leave you without power at the worst moment. The same upkeep that keeps it dependable keeps it safe.

2 How often should I change the oil?

A new generator usually needs an early break-in change after the first few running hours. After that, a commonly cited range is somewhere around every 50 to 100 running hours, or once a year if you run it less — but your own manual is always the final word, and a hard-working unit may want it sooner.

3 Can I add fuel while the generator is running?

No — never. Fuel and its vapors can ignite on a hot engine or exhaust. Shut the generator off, let it cool down, then refuel away from any flame and wipe up any spill before restarting. This is the one fire rule worth treating as absolute.

4 What makes fuel go bad, and how do I prevent it?

Gasoline breaks down over weeks and months and leaves deposits that gum up the carburetor — a classic no-start. Add a fuel stabilizer, use gasoline within a few months, and rotate your supply. Ethanol-free gas, if you can get it, stores better.

5 When should I stop and call a small-engine shop?

Routine oil, air filter, fuel, and cord care are fine to do yourself. But carburetor cleaning or rebuilding, engine repair, fuel leaks, and rough running are jobs for a small-engine shop — and any house wiring is a licensed electrician's work. When in doubt, leave it off until a pro has looked.

6 Does keeping it maintained change the carbon-monoxide rules?

No. Every generator gives off carbon monoxide no matter how well it's kept, so it always runs outdoors only, at least 20 feet from the house, exhaust pointed away, with battery-backup CO alarms inside. Testing those alarms is part of your upkeep, too.

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).
