Husqvarna Leaf Blower How to & Troubleshooting Guide

If you have leaves, grass cuttings, and other debris on your property, raking it all can take up a very long time. It can also be tiring, and you may not finish the job, especially if you have other outdoor tasks to complete. These are what make leaf blowers an excellent choice for cleaning up your lawn. They come in diverse sizes, so you can choose a size that fits your property. 

There are handheld, those you can carry on your back, and those you can push around your property. You need to pick an option that works for the amount of work you will be doing.

If you have many leaves and a large lawn, using one you can carry on your back is always an excellent choice. Several companies manufacture leaf blowers today, but Husqvarna is one of the best. 

Husqvarna is a Swedish company and has been in business since the 1600s. The company makes leaf blowers in different sizes and for various prices. That means any person can find a suitable Husqvarna leaf blower for them.

However, if you plan to buy one, it is essential to learn how it works and repair it. Here is a comprehensive guide to using and troubleshooting your Husqvarna leaf blower.  

How to start a Husqvarna leaf blower

When you get your new leaf blower home, the first thing you will need to do is test it out. You cannot do that if you do not know how to start it. Husqvarna leaf blowers are easy to use. Ensure that you check the type of leaf blower you have; it could be gas or battery operated. 

How to start gas Husqvarna leaf blowers 

Follow these steps to start your gas-powered leaf blower. 

  • Start by mixing the gas and oil carefully. Husqvarna leaf blowers use up gas and oil in a ratio of 50:1. Therefore, it is advisable to mix the gas and oil before putting it into the leaf blower to ensure that it is perfectly mixed. Consider using an empty gasoline can and shaking the contents vigorously. You can mix enough fuel to last up to 2 weeks, but be careful only to mix enough for your work. Gasoline mixtures should not be stored long-term, and you should not use yours after three weeks. 
  • Next, ensure that the gas tank is clean before pouring in the gasoline mixture. Be careful not to spill it. Remember to only put oil up to the Full line on your gas tank and wipe off excess oil and close the gas tank.  
  • Then press the primer bulb. You will need to press it up to 10 times or until you notice that it is filling up with the fuel. You do not need to fill the primer bulb with fuel.
  • Next, move the choke lever to the left, where there are two Hs. The choke lever is right below the primer bulb. 
  • Hold the blower on a flat surface and pull the starter handle three times, then move the choke lever to the first H symbol position. Next, pull the starter handle again until the engine starts, then allow it to warm up. You can now move the choke lever fully to the right. 

How to start a battery-powered Husqvarna blower

Battery-powered Husqvarna Blowers are better for the environment. They are portable, efficient, and quieter than gas-powered blowers. Follow these steps to start your battery-powered leaf blower. 

  • Ensure that the machine is clean and debris-free before putting in the fully charged battery. Next, insert your Husqvarna battery into the battery holder. It should slide in smoothly without sticking. 
  • Push the battery unit as far as it goes; listen for the click, which means it is locked in place. 
  • Finally, use the ON/OFF button to switch it on and the power trigger to pick blower speed.

What kind of gas does the Husqvarna leaf blower use?

Like many other brands, Husqvarna uses regular unleaded fuel. That means you need to use gasoline with 89-octane or higher and a 10% ethanol blend.

How to mix gas and oil for Husqvarna leaf blower 

Mix gas and oil for a Husqvarna leaf blower at a ratio of 50:1. Follow these easy steps. 

  • Pour gas into the can and add the right amount of oil. 
  • Close the can and shake it vigorously until the two are well mixed. It is advisable to mix large amounts at once if you use the blower often. However, gas mixtures should not be used after three weeks of storage, so check that you only mix fuel you can use in that time.

Husqvarna 125B leaf blower will not stay running 

It is frustrating if you have work to do and your blower does not work correctly. If you use your Husqvarna 125B professionally, that leads to significant income loss. A leaf blower that keeps turning off is even more frustrating. Here are some of the causes of this problem and how to fix them, so your blower works correctly. 

Old fuel

Often after a job, you may have a little oil left in the gas tank of your leaf blower. It is not advisable to leave it there till the next time. The fuel is likely to thicken and clog your carburetor, meaning that your leaf blower will keep starting and stopping. If that is the issue, follow these easy steps. 

  • Ensure that you do not use fuel that you have stored for long periods in your Husqvarna 125B. 
  • Use a carburetor cleaner to unclog your carburetor. You will not need to disassemble your leaf blower. If cleaning does not solve the problem, you may replace the carburetor. 
  • Check the fuel filter for fuel residue and other debris that may be clogging it. You can choose to clean it, but it is always best to replace a clogged filter. 
  • Fuel stabilizers help keep fuel fresh and prevent thickening, which causes clogs. 

Clogged fuel filters

A clogged fuel filter causes your leaf blower engine to start, run and then die after a short time. The fuel filter is responsible for removing dirt and debris from your oil. It can get clogged after a while, making it impossible for oil to flow from the gas tank to the engine.

You can correct the issue by cleaning the filter. However, consider buying a new one and replacing it if the filter is damaged.  

Spark plugs

The spark plug ignites air and fuel as the piston in the cylinder rotates. If it is not working, your leaf blower will only run for a short time and stop. To fix this problem, replace the spark plug. 

Clogged fuel lines

Fuel lines transport fuel between the gas tank and engine. Obstructions in the fuel lines will mean low amounts of fuel will get through, which will result in your machine turning on and off.

If there are cracks in the fuel lines, they will also cause your leaf blower engine to die unexpectedly. You can clean clogs in the fuel lines, but cracked lines must be replaced immediately they occur. 

How to adjust the carburetor on a Husqvarna leaf blower

You can adjust the carburetor on your leaf blower at any time. However, the timing of your Husqvarna carburetor is crucial because it determines how the machine runs. If the timing is low, the blower will slow and stop working suddenly.

On the other hand, if the timing is too fast, the leaf blower will constantly be in overdrive. Both these conditions affect the quality of work you will be able to complete using your Husqvarna leaf blower. Follow these steps to modify the carburetor on your leaf blower. 

  • Begin by turning the mixture screw until it barely sits on the seat. 
  • Next, turn it one and half times to the left. 
  • Do the same thing with the idle speed screw.
  • Ensure that the machine is running and adjust the screw until you are comfortable with how your leaf blower is running. 
  • Ensure that you raise the throttle to check whether the new settings can handle an increased power load. 

How to increase the power on your Husqvarna leaf blower

Depending on your tasks, you may want more power from your Husqvarna leaf blower. There are several methods you can use to increase the power of your leaf blower at home. 

Routine Maintenance

One of the ways to ensure that your Husqvarna leaf blower serves you for a long time is to maintain it regularly. Ensure that you do not leave fuel in the tank during storage, clean it regularly and change the filters too. These will ensure that the machine has high-powered performance throughout. 

Changing the impeller blades

If you want to increase power on your blower, consider changing the fans. The fans are crucial in leaf blower efficiency, and a few modifications can create a high-powered leaf blower. For example, you can change the fan angle to raise your leaf blower’s CFM.

Bear in mind that this modification will make your blower noisier. It is also crucial to ensure that your blower motor can handle this modification. Using new fans is another way you can make your blower more powerful.

There are several options available, and you can choose the ones that work for your Husqvarna leaf blower. 

Accessories

Another excellent way to improve power on your blower is by installing accessories. There are many leaf blower accessories in the market today, and you can identify those that are compatible with your machine.

Nozzle extensions are the most common blower accessories. They help increase your leaf blower MPH, making it high-powered and better for cleaning wet and resistant leaves. If your leaf blower has a vacuum, you can also get a mulcher kit for it. 

Husqvarna cordless leaf blower not charging

Husqvarna cordless leaf blower battery lasts between 1 hour and 1.5 hours. The company generally uses Lithium batteries for its products. Therefore, it is not advisable to use other batteries or non-rechargeable batteries on your Husqvarna leaf blower.

In addition, the battery takes about 30 minutes to charge fully. Here are some of the reasons why the blower is not charging. 

  • Lack of power can be one of the reasons that your leaf blower is not charging. You can plug in another household appliance to see whether it charges or use a different socket. If that’s the problem, making repairs will ensure your blower charges typically. 
  • Over time your battery can become damaged by regular use. That means it will not be able to hold power no matter how long you charge it. You can check if this is the problem by plugging your cordless leaf blower into a wall socket and starting it. If it starts, the battery is the problem. Bear in mind that you can only do that with some models, not all of them. 
  • Check your battery voltage if your Husqvarna has an external charger. If you have a spare, you can insert it into your machine to see whether it starts. If it does, then the other battery is damaged, and you should replace it. 
  • A damaged charger will not charge your leaf blower. Check the charger for damage and if there is any, replace it. 

Husqvarna cordless leaf blower not turning on

A cordless leaf blower that does not turn on can be very frustrating. It means you will not get the work done, and if you are professional, you will lose money or a client. If your blower will not turn on, here are the possible reasons. 

  • The battery is not charged. If you did not recharge the battery before using the leaf blower, you might have problems getting it started. So first, check that it is charged and if it is not, charge it. 
  • An improperly inserted battery. If you do not insert your battery correctly into the blower, then the blower will not turn on. Make sure that you push the battery into the slot as far as it will go and only stop when you hear a click. That will ensure the machine works correctly. 
  • A jammed fan or impeller. If there is a stick or other debris in your impeller, it will not turn. Check for grinding sounds from the impeller by moving it by hand if there is no debris. Grinding sounds suggest worn-out bearings, meaning they lock up when you turn on your power tool. 
  • Problems with the electric motor. Check the electric motor by opening the inspection hatch. Make sure that the spindle in the middle turns. If it does and the machine still won’t work, you may need to replace your electric motor. That is because the electric motor brushes are damaged. 

Why does my battery-powered leaf blower keep shutting off?

If you are ready to start work in your yard, a leaf blower that keeps shutting off can be a significant inconvenience. Here are the reasons why your leaf blower does that. 

Damaged motor

Most blowers have a brush-style motor. If the brushes wear out, the power tool will start then stop. Check your motor and if it is a problem, replace it, and your blower should work typically. 

Short-circuiting in the system

If you have loose wires in your leaf blower electric system, they can cause it to stop suddenly. Inspect all connections, terminals, and loose cables as they can make the electric motor stop suddenly. Ensure that you also check that the ON/OFF switch is working correctly.

The fan or impeller

Ensure that a stick or other debris is not jammed in your impeller or fan. That can happen as you work and cause the machine to stop suddenly. 

Husqvarna leaf blower bogging down when the choke is full off

It can be very confusing if your leaf blower keeps bogging down when the choke is full off. If you have noticed that the engine dies when you try to run your leaf blower at full power, you can find the problem by following the following troubleshooting tips. 

Check the air filters

The air filters let the air into the engine. In the process, they also clean it, and over time they can get clogged with debris. If your air filter is filthy and clogged, your leaf blower will keep bogging down. To check the air filters, follow these easy steps. 

Open the air filter cover, and you will see the filter 

If the filter is torn or has cracks, consider replacing it with a new one. 

  • On the other hand, if the filter is dirty, you can use warm soapy water to clean it. 
  • Ensure that you allow it to dry entirely before remounting it. That said, filters are not expensive, and buying a new one is always a better idea compared to washing. 
  • If you are using your leaf blower after a prolonged storage period, check the state of the air filter before you switch it on. You may find that it has a large amount of dirt and debris from the work you did with it before storage.

Check the fuel filter

If the air filter is working, check whether there are any problems with the fuel filter. The fuel filter ensures that debris from the fuel tank does not get into the engine through your blower’s fuel lines.

Unfortunately, that means it can get clogged with fuel residue and other debris over time. Remember, if you leave fuel in your leaf blower for a long time, it starts to thicken. The thickened fuel can clog the filter and affect the power tool’s operation.

If your fuel filter is clogged, you need to replace it. Follow these easy steps to replace your fuel filter.

  • Start by detaching the fuel line and the spark plug from the fuel tank
  • Carefully remove your old filter and put the new one in its place. 
  • Reattach the fuel line and the spark plug to the fuel tank.  

Check the carburetor

The carburetor is an essential part of the Husqvarna leaf blower system. If it is not working correctly, it will affect how your leaf blower works. Here are the reasons your carburetor is not working correctly. 

Dirty carburetor

If your carburetor is dirty, it may cause your leaf blower to keep bogging down. Clean your carburetor thoroughly, and that should solve the problem. To clean, follow these easy steps.

Empty all excess gas. 

Next, open the carburetor and spray it with a good-quality carburetor cleaner. 

Close and reattach it to all components. 

Cracked carburetor

If you notice cracks on the carburetor while cleaning it, you need to replace it immediately. 

Bad carburetor adjustment

If your carburetor is not well adjusted, your leaf blower may become bogged down after you start it. To make adjustments, find the adjustment levers and move them to produce high performance with low smoke. Then, check whether the blower revs fluently to test whether you did a good job. 

How to clean and repair a fuel Husqvarna leaf blower

Battery-operated leaf blowers do not need as much maintenance as gas blowers. Here are the steps to follow when cleaning and maintaining them.

  • Wipe the leaf blower using a cloth. 
  • Check the blower for missing or damaged parts. If some parts are loose, tighten them. Make sure that you also replace missing and damaged parts. 
  • Inspect the air intake for things that will affect airflow, including leaves and other debris. Then, wipe the area clean with a piece of cloth. 
  • Make sure that you also wipe off the battery after use. Check for signs of damage before storage. If your battery has cooling vents check them for debris and remove it. 
  • Store your Husqvarna leaf blower battery in a cool, dry place. Heat and water can easily damage lithium batteries. It is best to leave a 40% charge in the battery for winter storage and about 20% regular storage. Your Husqvarna battery leaf blower will not run out to0% but is built with safeguards so that 10-20% battery charge remains in store.

A hole in your blower bag is inconvenient, as debris will keep spilling out. It is therefore essential to fix any gaps that you see immediately. That said, if your bag has too many holes, you should replace it. Follow these easy steps to patch a tear on your leaf blower bag. 

  • You will need some towel material and high-quality glue. 
  • Empty the bag and brush off any dirt particles around the hole.
  • Use the dimensions of the hole to cut out a patch from the towel material. 
  • Apply glue on the patch and press the patch on the hole from the inside. Make sure you place wax paper on the patch to prevent glue seepage. 
  • Place a piece of wood on the patch and use a heavy object on it overnight. 
  • The patch should hold for a long time. 

Husqvarna leaf blower clunks when starting 

Strange noises coming out of your leaf blower can be very distressing. Although they start as barely audible blower clicks, they can become loud and result in expensive repairs in the future. So here are some of the reasons why your leaf blower keeps making clicking sounds. 

Problems in the spark plug

Damaged spark plugs affect the flow of the electric current that starts up the engine. You will hear the noise every time you try to start your leaf blower or when the engine is idling. If that is happening on your leaf blower, check your spark plug because it is on the outer side of the blower. You can fix it by doing the following things.

  • Begin by removing the spark plug.
  • Carefully check it for build-up corrosion or cracks on the electrode. 
  • Replace it with a new one if you spot any signs of damage. 
  • In case it is in good condition, clean it and reinstall it. 
  • Remember, you need to change your spark plug after using your leaf blower for 20 hours. 

Damaged ignition switch

If the spark plug is working correctly, you need to check the ignition switch. You can easily replace it if damaged by opening the leaf blower housing. Follow these easy steps to replace a damaged ignition switch. 

  • Start by opening the housing to expose the switch. Then, depending on your model, remove all the screws along with the sparkplug. 
  • Next, remove the throttle linkage so that you can access the ignition switch wires and disconnect them from the engine. 
  • Remove the screw to detach the earth wire from the engine.
  • Carefully pull the switch from the engine. 
  • To install the new switch, carefully place it into the housing and realign the wires through it to ensure none get pinched when you close the housing when you finish the job.
  • Place the ground wire on top of the engine and secure it with a screw.
  • Next, reconnect the other ignition wires. 
  • Replace the throttle linkage by looping the end of the throttle cable around the hook on the link and then hoisting its other end onto the trigger.  
  • Carefully replace the housing and secure it in place using the screws. Next, replace the spark plug, and test out your leaf blower. 

Damaged housing

Husqvarna leaf blower housings are usually made with plastic.
