Champion 41533 Generator: Specs, Maintenance, Problems & Replacements

The Champion 41533 is a 9,200 starting watt, 7,200 running watt gasoline generator with wireless remote start. Champion no longer sells it, but many are still sitting in garages and sheds, ready for the next power cut.

If you own one, or you are thinking of buying a used one, this guide is for you. It covers the official specs, how the remote start really works, the full maintenance schedule, the problems owners run into, and the parts you are most likely to need.

At the end you will also find the modern Champion generators that come closest to the 41533, in case it is time to move on.

What Is the Champion 41533?

The 41533 is an open-frame portable generator from Champion Power Equipment. Its manual describes it as a gasoline engine driven AC generator, built to power lighting, appliances, tools and similar equipment.

Three things made it popular:

• Real 240-volt power. It supplies 120/240 volts, so it can feed a transfer switch or run a well pump.
• Three ways to start. A wireless remote, a push-button electric start and a pull cord as a backup.
• Wheels included. It ships with a wheel kit and a support leg, which matters on a machine that weighs over 200 pounds.

You may see slightly different wattage figures on old store listings. This guide uses the numbers printed in Champion’s own manual: 7,200 rated watts and 9,200 starting watts.

Champion’s website no longer shows a product page for the 41533. It lists only the operator’s manual. That tells you the model has left the current lineup, though Champion still offers the manual and technical support.

Champion 41533 Specs

The manual also says the generator is rated for continuous use at temperatures up to 104 °F. It can run for short periods from 5 °F to 122 °F.

The Power Panel and Outlets

The panel gives you three kinds of outlet, which covers most home and job-site needs.

You also get:

• Intelligauge. A three-mode digital meter that shows running hours, voltage and hertz.
• Push-to-reset circuit breakers that protect the generator from overloads.
• A battery switch and an ignition switch. Both must be on for the remote to work.
• A ground terminal for connecting a ground rod where local rules require it.

So what can 7,200 running watts handle? Champion’s own wattage chart gives typical figures for home appliances. A refrigerator uses 150 to 400 running watts. A half-horsepower well pump uses 750 to 1,000. A furnace fan uses 300 to 800, and a 10,000 BTU window air conditioner uses 900 to 1,200. Add those up and the 41533 still has room for lights, a microwave and a TV. Always check the labels on your own appliances, and use our Generator Size Calculator to be sure.

How the Wireless Remote Start Works

The remote is the feature people love most, and the one that causes the most confusion. Here is what the manual says.

The system has four parts: a receiver module on the generator, the handheld remote, a battery switch and an ignition switch. The remote only works when both switches are on. It reaches up to 80 feet.

When you press START once:

• The module works the choke for you. Do not adjust the choke yourself.
• The engine tries to start up to six times.
• No power reaches the outlets for about 15 seconds. This delay lets the engine reach full speed before any load is applied.

Press STOP once to shut the generator down.

This single habit prevents the most common complaint about remote start generators: a machine that will not start on the day you need it.

Starting and Stopping It the Right Way

Follow the manual’s order and the generator will last longer.

1. Put it on a flat, level surface outdoors. The low-oil sensor can stop the engine if the generator is tilted.
2. Unplug or switch off every load. Never start or stop the generator with appliances running.
3. Turn the fuel valve on, then press the battery switch and the ignition switch to ON.
4. Start it. Press START once on the remote, or hold the ignition switch at START for no more than five seconds. Wait ten seconds before trying again.
5. Let it warm up for a few minutes, then plug in your largest load first and add the rest one at a time.

If the battery is flat, use the pull cord. The manual says to keep the choke on for one pull only, then move it to RUN. Too much choke floods the engine.

To stop it, unplug the loads and let the engine run for a few minutes with nothing connected. Turn the fuel valve off and let the engine run until it stops by itself. Then switch off the ignition and the battery switch. Running the carburetor dry like this is one of the best things you can do for an older generator.

Fuel and Oil

The 41533 is not fussy, but it does have rules.

• Fuel: clean, fresh regular unleaded gasoline with an octane rating of 85 or more. Ethanol content must be less than 10%. Never mix oil into the fuel.
• Leave space in the tank. Fuel expands, so stop at least a quarter inch below the top.
• Oil: 10W-30 automotive oil. The crankcase holds up to 1.16 quarts. Do not overfill it.
• Check the oil every day you use it. The engine has a low-oil shutoff and will stop if the level drops too far.

The manual is direct about ethanol blends. They absorb water, and over time they can separate and leave a watery mess in the tank and carburetor. Champion advises shutting off the fuel, running the engine dry and draining the tank whenever the generator will sit for more than 30 days. Our guide on how long gasoline lasts explains why.

Champion 41533 Maintenance Schedule

This is the schedule from the operator’s manual. Service more often in dusty, hot or heavy-load conditions.

A few details that save trouble:

• The air filter is foam and washable. Wash it in detergent and water, dry it, soak it in clean engine oil, then squeeze out the excess.
• Valve clearance is 0.005 to 0.007 inch on the intake and 0.007 to 0.009 inch on the exhaust.
• Do not hose it down. Water can get into the fuel system and the generator windings. Use a damp cloth, a soft brush and low-pressure air.
• Leave the governor alone. Tampering with it voids the warranty and can damage your appliances.

Common Champion 41533 Problems and Fixes

The manual’s troubleshooting chart is short and practical. Here it is in plain English.

Two more problems do not appear in that chart but follow directly from the manual’s warnings.

The remote does nothing. Check that both the battery switch and the ignition switch are on. If the battery switch does not light up, the battery is flat or a cable is loose. Charge the battery, or start the generator with the pull cord and let it run.

It will not start after storage. Old fuel is the usual cause. If the generator sat with gasoline in it for months, drain the tank and carburetor and start again with fresh fuel. Our step-by-step guide to a generator that won’t start walks through the checks in order.

Parts and Tune-Up Items

You only need a handful of items to keep a 41533 healthy.

• Spark plug. The original is an NHSP F6RTC. The manual lists the NGK BPR6ES or an equivalent as the replacement. Gap it to 0.028 to 0.031 inch.
• Oil. Any quality 10W-30 automotive oil. You need just over one quart per change.
• Air filter. A washable foam element. Replace it if it tears or crumbles.
• Battery. A 12 volt, 15 Ah unit. Take the old one with you to match the size and terminals.
• Fuel stabilizer. A bottle of STA-BIL Storage protects stored gasoline.
• Fuel line. Due every 3 years according to the schedule.

For exact part numbers, use the manual and diagram search on Champion’s website. The operator’s manual includes full parts diagrams for both the generator and the engine.

Living at altitude? The manual says engine power drops by about 3.5% for every 1,000 feet above sea level. Champion can supply a high altitude main jet for use above 5,500 feet. Do not run that jet at lower elevations.

The one accessory worth buying on day one is a battery maintainer. The manual says the battery should be fully charged at least once a month, at no more than 1.5 amps.

How to Store a Champion 41533

For short breaks, the manual keeps it simple. Start the generator at least once every 14 days and let it run for at least 20 minutes.

For longer storage, follow these steps.

1. Add fuel stabilizer to the tank and run the engine for a few minutes so treated fuel reaches the carburetor.
2. Turn the fuel valve off and let the engine run until it stops.
3. Let it cool, then clean it with a cloth and a soft brush.
4. Change the oil.
5. Protect the cylinder. Remove the spark plug, pour in about half an ounce of oil, turn the engine over slowly and refit the plug.
6. Switch off the battery switch and, for long storage, disconnect the battery leads.
7. Store it in a clean, dry place out of direct sunlight.

That battery step matters on a remote-start model. The manual warns that the ignition switch, fuel valve and battery switch should all be off in storage, so the generator cannot be started by accident. Our full guide on how to store a generator has more detail.

Safety: Where to Run It and How to Connect It

The 41533 comes from a time before portable generators had built-in carbon monoxide sensors. Its manual does not describe any CO shutoff, the feature Champion now calls CO Shield. That makes placement even more important.

The manual adds two clearance rules for the generator’s own sake. Keep it at least five feet from anything that can burn. Leave at least three feet of open space on every side so it can cool.

Connecting it to a house. The manual is blunt here. Plugging a generator into a household outlet can send power back down the utility lines and kill a line worker. If you want to power your home’s circuits, have a qualified electrician fit a transfer switch or interlock, and use the 120/240-volt 30-amp twist-lock outlet. Tell the electrician that the manual describes the generator’s winding as isolated from the frame, because that affects how the switch is wired.

Our guide to connecting a generator to your house explains the options, and the generator safety tips cover everyday use.

Is a Champion 41533 Worth Repairing or Buying Used?

Often, yes. It is a simple machine with a carburetor, a pull cord backup and no complicated electronics beyond the remote module. Champion still publishes the manual and parts diagrams.

But go in with clear eyes.

• There is no warranty left. The 41533 came with a 2-year limited warranty that covered the original buyer only. It could not be transferred.
• It has no CO shutoff and runs on gasoline only.
• It is heavy. At 212.7 pounds net, it needs a smooth path and two people for any step or slope.

If you are looking at a used one, check these before you pay.

• Ask to start it from cold, first with the pull cord and then with the electric start.
• Read the running hours on the Intelligauge meter.
• Watch the voltage and hertz readings while a load is plugged in. They should stay steady.
• Pull the dipstick. Black, gritty oil suggests poor care.
• Smell the fuel. A sour, varnish-like smell means old gasoline and a carburetor that may need cleaning.
• Check that the remote is included and that the battery holds a charge.
• Look for cracked fuel lines, a torn air filter and a rusty tank.

Modern Replacements for the Champion 41533

Generators have moved on since 2013. The newer Champion models add three things the 41533 lacks: a carbon monoxide shutoff, a choice of fuels and a longer warranty.

Common Mistakes With the Champion 41533 (and the Fix)

Pro Tips for Champion 41533 Owners

• Run it every two weeks for 20 minutes. That is the manual’s own advice, and it keeps the fuel system and battery healthy.
• Keep a spare spark plug and a quart of 10W-30 on the shelf. Both are cheap and both can end an outage early if missing.
• Write the oil change date on a piece of tape and stick it on the frame.
• Add the biggest load first. Let the engine settle, then add the next one.
• Test the remote from indoors before storm season, so you know where it works.
• Keep the pull cord in good shape. It is your backup when the battery fails.
• Save the manual as a PDF on your phone. You will want the troubleshooting chart when the lights are out.

Real-Life Scenarios: What Should You Do?
