How to Use a Champion Dual Fuel Generator for the First Time

Add the correct oil, place the generator outdoors well away from the house, pick gasoline or propane, then start it with no load connected and let it settle before you plug anything in. To turn it off, unplug your loads, let the engine run a minute or two, switch the engine off, and close the fuel supply. Controls differ by model, so keep your Champion owner's manual open and treat it as the final word.

Before you start: unbox and prepare

Most portable generators ship with the engine dry, which means no oil in the crankcase. Read the manual first and find the oil fill point, the fuel selector, the start controls and the outlet panel. Running the engine without oil can ruin it in seconds, so this step comes before anything else.

Set the generator on a flat, level spot outdoors. Level ground matters because the oil level reading and the low oil shutdown depend on it. Install any parts the box asks for, such as wheels or a handle kit, and connect the battery if your model has electric start and the manual says the battery needs to be hooked up.

Add the oil type the manual recommends, up to the fill mark. Check the dipstick with the generator level.
Confirm the generator is off and nothing is plugged in.
Check for loose parts, damaged hoses and anything blocking the air vents.
Keep the manual, a flashlight and a fire extinguisher nearby.

Choose gasoline or propane

A dual fuel generator runs on either fuel. Gasoline is easy to measure with the tank gauge and usually gives the higher output. Propane stores well and burns cleanly, which suits emergency kits and long outages when you can keep a spare cylinder.

Expect less output on propane. Our comparison data shows the same pattern on other dual fuel units: the Westinghouse iGen12000DFc lists 9,000 running watts on gasoline and 8,100 on propane, and the iGen5000DFc lists 3,900 versus 3,500. We do not have Champion figures in our data, so check your own model's label for both numbers. If you are still choosing a unit, our best dual fuel generator page puts these specs side by side.

Fuel	Good for	Keep in mind
Gasoline	Higher output, easy fuel gauge reading	Fuel ages in storage, so use fresh fuel and do not overfill
Propane	Clean burning, easy storage, spare cylinders	Lower running watts, and the hose and regulator must be sealed tightly

The exact order changes by model, but the basic sequence is the same. Start with no load connected, because the engine needs a moment to stabilize.

Place the generator outdoors, level, with the exhaust pointing away from windows, doors and neighbors.
Check the oil level one more time.
Set the fuel selector to gasoline or propane. For gasoline, fill the tank without overfilling and leave room for expansion. For propane, connect the hose to the regulator and cylinder, open the cylinder valve slowly, and check the connections with soapy water. Bubbles mean a leak.
Turn the fuel valve on if your model has one, then set the choke if the manual calls for it on a cold start.
Turn the engine switch to run. Then start it with the button, the key, the remote or the recoil pull, depending on your model.
Once the engine runs smoothly, move the choke to run if you used it, and wait a minute or two before adding any load.

Break-in and your first run

A brand-new engine benefits from a gentle first session. Many owners run the generator for a short time under a light load, then change the oil at the interval the manual gives. Follow your manual on this, since break-in guidance can differ from model to model.

Add loads one at a time, starting with the biggest motor-driven item such as a refrigerator or pump. Use the running watts on your generator's label as your limit and remember that motors can briefly draw more when they start. Our best generator page explains how to match running watts to what you need to power.

Use heavy-duty outdoor extension cords rated for the load, and never run cords under rugs or through doorways that pinch them. If the generator has a 240V outlet, a transfer switch or interlock kit installed by a licensed electrician is the safe way to power a home circuit.

Shutting down in the right order protects both the engine and your equipment.

First, switch off or unplug every appliance. Then let the engine run with no load for a minute or two so it cools a little. Turn the engine switch off. If you were running on propane, close the cylinder valve first, let the engine burn off the fuel left in the line until it stops, then switch off. If you were running on gasoline, close the fuel valve if your model has one.

Let the unit cool before you move it or cover it. Never refuel a hot or running generator.

Safety rules that matter

Generators produce carbon monoxide, which you cannot see or smell. Never run one in a garage, basement, shed or near an open window, even with the door open. Keep it well away from the house and point the exhaust away from every opening. Install battery-powered CO alarms inside your home.

Gasoline and propane are both flammable. Store fuel outside living spaces, keep it away from the hot engine and any spark, and wipe up spills before you start. Keep the generator dry, since rain and wet hands combined with electricity are dangerous. Use a dry, covered, ventilated spot such as an open-sided canopy designed for generators.

Engines are loud. Wear hearing protection if you will be working next to it for a long stretch. Wear eye protection when you pour fuel or handle tools around the unit.

Common first-time problems

If the engine will not start, check the oil level first, since low oil shutdown can stop it. Then check that the fuel valve and fuel selector are set correctly, that the tank or cylinder has fuel, and that the engine switch is in the run position.

If it starts then stalls, the choke may be in the wrong position, or a load may be too big for the fuel you chose. If it runs but nothing powers up, check the breaker or reset button on the panel and confirm your cord is rated for the load. For anything else, use the troubleshooting section of your manual or contact Champion support.

Frequently asked questions

Can I switch fuels while the generator is running?

Some models allow it and some do not. Check your manual. The safe habit is to shut the unit down, change the fuel setting, and restart.

How often should I run it when I am not using it?

Running it briefly on a regular schedule keeps the engine and fuel system in better shape. Your manual gives the recommended interval and storage steps.

Do I need a special cord for the 240V outlet?

Yes. Use a cord or cable with the plug that matches the outlet and a rating that fits the load. Home connections should go through a transfer switch or interlock kit installed by a licensed electrician.

Can I run it in the rain?

Not uncovered. Use a generator-rated cover or canopy that keeps water off and still lets exhaust and air flow freely, and keep it well away from the house.
