10 Causes of RedMax Leaf Blower Stalls, Stutters, and Death

Your leaf blower is giving you trouble; it won’t stay on and you have to constantly restarting it. I’ve compiled a list of potential factors contributing to this issue, along with advice for addressing each.

When the air, fuel, and spark are insufficient, a RedMax leaf blower will start, stall, and die.

This might be the result of a number of issues, including an outdated fuel supply, a filthy carburetor, a clogged fuel filter, a clogged fuel line, a blocked vent on the fuel tank, a faulty spark plug, a faulty ignition coil, a clogged spark arrestor, or an inappropriate choke setting.

To prevent your RedMax blower from starting, always disconnect the spark plug wire. To avoid damaging the engine, you should wait until all moving parts have stopped and the temperature has dropped.

When troubleshooting, repairing, or using a piece of equipment, be sure to first read and follow any safety recommendations found in the handbook. If you don’t feel confident in your ability to conduct the repair safely due to a lack of experience, training, or health, it’s best to call in an expert.

Top 10 Causes of a Deadly RedMax Blower Shutdown

1. RedMax Leaf Blower with Incorrect Choke Setting

To control the quantity of air that is sucked into the engine at startup, the choke is opened and closed using the choke lever.

To turn over a cold engine, you must have the choke lever in the CLOSED position. With more gasoline and less air, the engine will run more efficiently.

If your engine is cold, you should start it by closing the throttle. The RedMax will not continue to operate without the choke lever being moved to the OPEN position once the engine has been started and warmed up.

2. RedMax Leaf Blower Air Filter Clogging

If your RedMax blower suddenly turns off or loses power, the air filter should be one of the first items you examine. The engine is safeguarded by the air filter, which traps dust and other particles before they may damage the engine.

Working in such dusty conditions means that the air filter will quickly get clogged and will need to be cleaned or replaced. If the filter gets dirty enough that not enough air can get through it, your RedMax blower may splutter and stop working.

If your air filter is broken, moist, extremely dusty, or doesn’t seal correctly, you should get a new one.

Never, not even to get the work done faster, operate your blower without a filter. If dirt gets inside the engine, it can wear it down and perhaps cause harm.

In general, you should replace your air filter once a year, or more frequently if you find that it is in bad condition after checking it on many occasions.

You should inspect your RedMax leaf blower more often if you use it more often than the typical homeowner or if you use it in exceptionally unclean circumstances.

• Air filtration FELT for the RedMax fan:
  • Take it apart and brush off the dirt to clean it. As an alternative, you might use a solution of mild dish soap and water to clean it.
  • Lay flat to dry after rinsing under running water. Clean the air filter housing and cover with a damp cloth before reinstalling.
  • If the filter is a dark color, I know I need to replace it to keep the air clean.

• PAPER air filter and FOAM pre-filter for the RedMax fan:
  • Take off the air filter and pre-filter.
  • Clean the air filter housing and cover by wiping it down. Keep the air filter free of dust and debris.
  • To disinfect the foam pre-filter, just wash it with a solution of mild dish soap and water.
  • The water should be clear after rinsing. Rinse the filter in cold water and lay it flat to dry.
  • Check the condition of the paper filter. Throw it out and get a new one if it’s soiled. If not, feel free to put it to good use again.
  • Put in the dry pre-filter and the air filter.
  • The air filter cover must be reattached.

For information on how to clean the filters in your RedMax leaf blower, which may be of a few various sorts depending on the model you have, please see the handbook that came with your specific unit.

3. Incorrect Fuel Use with a RedMax Leaf Blower

Gasoline quality and age do make a difference in the performance of your RedMax leaf blower. Problems with your fuel system and the performance of your blower can worsen if you use old gas or gas with a high concentration of ethanol.

The ecologically favorable substance ethanol is added to most gasoline types. Though maize is commonly used to produce this alternative fuel, other plants with a high starch content can also be used.

Water vapor in the air is drawn to the fuel system by ethanol because of its hygroscopic nature. The varnish and gums left behind by the ethanol and water combination can harm fuel system components and reduce fuel flow.

An excessive amount of ethanol will damage your blower’s little motor. Unleaded gasoline having an octane value of 89 or higher and an ethanol percentage of 10% or less is required.

Two-cycle RedMax leaf blowers need an oil/gasoline combination of 50:1.

Premium 2-cycle engine oil, such as RedMax MaxLife oil or an oil certified to ISO-L-EGD and JASO M345 FD, must be blended with gasoline for optimal performance. This oil is not like regular motor oil.

A damaged engine might be the consequence of using the incorrect type of oil or an inadequate amount of oil. Never use undiluted gas in your RedMax fan. We are in a dire gas shortage. Without 2-cycle oil, the engine will freeze up and stop working.

Fuel stabilizers are recommended for use in your RedMax fan.

After only 30 days, gas might start degrading. Fuel stabilizers, such as Sea Foam Motor Treatment, can be added to new fuel to extend its shelf life. When you use a fuel stabilizer, you can reduce the likelihood of problems caused by using stale gas.

It’s important to remember that some 2-cycle oils also act as a fuel stabilizer. Read the fine print to find out how long the stabilizer in the oil will keep the gasoline stable, even though the label claims it has one.

Don’t think it will work for more than 30 days if there is no specified duration. For additional information on how to pick the best gas and maintain it, see here RedMax leaf blowers run on this fuel.

4. RedMax Leaf Blower with Clogged Fuel Filter

A gasoline filter serves the same purpose as an air filter in that it ensures the blower only receives clean, dust- and debris-free air.

In the gasoline tank, you’ll find the fuel filter. It is connected to the gasoline line’s terminus. If dirt accumulates in the filter, your RedMax blower will stop working.

To prevent this, it should be updated on a regular basis. At least once a year, I said, you should swap out the filter. Changing the filter on a business blower every three months is recommended.

When you need to change the fuel filter on your RedMax, do the following:

• Clean the area around the gasoline cap with a rag to prevent dirt and debris from entering the tank.
• To use, take off the top.
• The gasoline tank’s fuel filter must be removed. The filter may be easily retrieved using a clean, bent wire.
• Take the filter out of the gasoline line once you’ve taken it out of the tank. The retaining ring must be protected at all costs. Hold tight to the fuel line ring.
• Simply insert the fuel filter’s male end into the fuel line and tighten the retention ring to secure the fuel filter to the line.
• Return the filter to its home in the gasoline tank.
• To fill the tank, replace the cap.

5. Broken RedMax Leaf Blower Fuel Lines

The fuel lines’ ability to carry gasoline might be clogged by the sticky deposits left behind by old fuel. If this happens, you’ll need to remove the gasoline line and replace it with one of the same size.

If the gasoline line is dry, fractured, or bent, it must be replaced.

6. RedMax Leaf Blower With Blocked Fuel Tank Vent

A vent is necessary for the RedMax fuel tank to allow air to circulate. When this opening is blocked, a vacuum is created in the gasoline tank.

Because gasoline can’t escape the tank due to the vacuum, the leaf blower stops working.

When a decent filter and clear fuel lines have already been ruled out as causes of a carburetor’s lack of fuel, a blocked fuel vent is the next likely suspect. Put your RedMax leaf blower to the test by setting it on a flat area.

If you want to start the blower, you need to let air into the tank, therefore loosen the gasoline cap. It is imperative that you keep the gasoline tank from leaking. The fuel cap should be replaced while the blower is operating.

Keep it running for a little longer. With the cap on, it sputters and dies, but when you take it off, it fires right up and keeps running, therefore the fuel tank vent is probably the culprit.

Put in a new fuel tank vent in its place. A fuel line leading from the tank will have this little component attached to it.

7. Sticky RedMax Leaf Blower Carburetor

If you want to get your RedMax leaf blower going and keep it going, you need a carburetor that blends the right amount of air and gasoline.

There are a number of potential causes for the blower to quit working, including blockage of the passages or malfunction of the many minor components.

RedMax carburetors often fail because of stale gasoline. In some cases, a carburetor can be cleaned or rebuilt to restore its functionality. If this does not work, you will need to replace the carburetor.

8. Faulty RedMax Leaf Blower Spark Plug

The spark plug was responsible for creating the first spark that kicked off the engine, so if it’s unclean or broken, the generator may splutter and die.

Take out the spark plug and inspect it. Replace the spark plug if the tip has turned a very dark color, the electrode is worn, or the porcelain is shattered.

If it seems in good shape, remove the spark plug wire and clean it with a wire brush before checking the electrode gap and reattaching it. A generator may stop working if there is a frayed wire or if the spark plug gap is not properly adjusted.

9. RedMax Leaf Blower with a Bad Ignition Coil

Make sure your spark plug is in good shape before you start looking for a broken ignition coil. In order to get the engine started, a spark plug requires a certain amount of voltage, which is supplied by the ignition coil.

Your RedMax leaf blower may cease functioning due to overheating of the ignition coil. There is a risk of a short circuit if the coil’s windings come undone.

An inoperable engine is the result of a spark plug or ignition coil that is unable to produce an arc that ignites the fuel/air mixture.

Use a high-quality spark plug. Determine if your ignition coil has a break in continuity by using an ohmmeter. If your ignition coil is malfunctioning, you should replace it.

10. RedMax Leaf Blower with Clogged Spark Arrestor

In order to prevent burns or fires from the leaf blower’s hot exhaust, it is equipped with a tiny metal screen. As carbon accumulates on this little screen, engine performance will suffer.

Take the wire off the spark plug. To get to the spark arrestor screen on most RedMax blower models, you’ll need to remove the engine cover and the engine exhaust cover.

Remove the spark arrestor screen with caution. Use a metal brush to scrub the display.

A new spark arrestor screen should be used if the old one is too dirty, broken, or has a hole in it to be effectively cleaned.

Keep your blower running at full speed on occasion to reduce carbon buildup on the spark arrestor. Allowing your blower to operate at low rates or idle for extended periods of time will lead to carbon accumulation.

If you’re still having trouble with your RedMax Leaf Blower, don’t hesitate to get in touch with your neighborhood retailer.
