Why Is My Husqvarna Chainsaw Smoking?

There are two possible sources of smoke that could come from your chainsaw while you are using it:

  • From the engine
  • From the chain and bar

To diagnose the issue and find a solution, you must first determine where the smoke is genuinely coming from.

Smoke From the Husqvarna Engine

Several distinct colors may be present if the engine is the source of the smoke:

  • The presence of black smoke suggests a clogged air filter.
  • White smoke signifies condensed water heating inside the chainsaw.
  • The presence of blue smoke suggests that the engine may be flooded.

Smoke From the Husqvarna Chain and Bar

When cutting wood, if smoke is flowing from the chain and bar, it can be caused by one of the following:

  • The type of chain is inappropriate for the particular sort of wood.
  • The bar’s lubricating holes are blocked.
  • The gauge’s depth setting is not appropriate for the specific type of wood.
  • The chain has been improperly sharpened or is dull.

Let me now discuss some of these causes of Husqvarna chainsaw smoke and some simple solutions to the problems.

5 Main Reasons & Solutions to Husqvarna Chainsaw Smoking Problem

Dirty Husqvarna Air Filter

An air filter built into your chainsaw controls the chainsaw’s airflow. Wood waste that accumulates in the air filter while you are chopping wood shocks it. As a result, it prevented the air from passing through and heating up your chainsaw.

If the chainsaw’s engine has a dirty air filter, it harms the engine and, if not managed appropriately, causes even more harm. Additionally, battery-operated devices function poorly and suffer serious damage. The chainsaw now emits white smoke as a result.

It’s fairly simple to fix this; all that’s required is that you use your chainsaw carefully and attentively. The air filter needs to be cleaned every five hours, or every two to three uses. A chainsaw lives longer and is kept from getting damaged by taking care of these minor details.

Excess Oil in Husqvarna Oil-Gas Mixture

Concerned that despite flawless management, your firewood chainsaw is still producing a lot of smoke? Do you mind if I tell you what the issue is? It comes as a result of the gasoline and oil mixture you are utilizing to power your chainsaw.

It is not enough to properly lubricate a chainsaw; you also need to be very careful about the oil-to-gasoline ratio. If the ratio is off, your chainsaw will cause you problems and emit smoke.

Check your chainsaw’s user manual or the one that comes with the chainsaw to avoid this. If you can’t find the handbook, you can read the ideal ratio online by searching for it on Google.

Take a measuring beaker and combine oil and gasoline in accordance with the ideal fuel ratio you have determined. You may set the chainsaw quickly by adding oil or gasoline in accordance with the ration you previously used if you can recall. In the alternative, you might throw it out and refill it with fresh fuel.

Additionally, you are always concerned that your gasoline is clean. If there are any contaminants, check them and change them. Always fill up your chainsaw with high-quality, brand-new fuel. These seemingly insignificant details add up, and you will undoubtedly notice a performance difference.

Poor Husqvarna Chainsaw Lubrication

A gas chainsaw experiences a lot of friction while in use. There are two levels of friction. On one level, the metal-to-metal friction between the chainsaw bar and chainsaw chain. The friction between the metal of the chain and the wood you are cutting is at another level.

When cutting, this intense friction exerts a lot of strain on the chainsaw and, if it is not properly lubricated, causes smoke to be produced. Your chainsaw needs to be properly oiled in order to withstand such high friction. Make sure to check for oil and thoroughly lubricate all necessary parts.

Dull Husqvarna Chainsaw Chain

If you want to make the most of your chainsaw, it’s crucial to regularly sharpen the chain. Such devices survive longer when they are managed and cared for properly. Maintain good positioning for your devices and meet all standards. One of the main causes of smoke is an unsharpened chainsaw chain, which can also cause a lot of other problems. Be aware of when a chainsaw chain should be sharpened.

These are symptoms if you are cutting wood under additional pressure or if there is fine wood dust being produced as trash. You need to be aware of these warning signs and sharpen your chainsaw immediately. Chainsaw chains should be well-sharpened. Rakers should be sharpened first, followed by the teeth, and the chainsaw bar should be checked last.

The correct instructions for step-by-step chainsaw chain sharpening are readily available. Make sure you complete each step in order and promptly sharpen your chainsaw. Then, you won’t have any trouble cutting, and the smoke problem will also be resolved. Learn How to Sharpen a Chainsaw Chain in our step-by-step guide!

Tight Chain

A tight chain is yet another factor contributing to chainsaw smoke. Regarding the chainsaw’s tension over the bar, you should use caution. Otherwise, you risk seriously harming both your chainsaw and chain. It shouldn’t be excessively loose or tight on the chain.

There is one general rule to follow when determining the ideal tension of a chainsaw chain. If you lift the chainsaw chain a little bit while keeping the drive link inside the bar nose, you have the proper amount of tension. Smoke and other harm to the chainsaw or chain are prevented by a tightly tightened chainsaw chain. Visit our How Tight Should a Chainsaw Chain Be? for our guide to keeping the right chain tension.

FAQs (Frequently Asked Questions)

Why is my Husqvarna chainsaw smoking?

This most frequently happens when the chain is dull and too much pressure is applied to the bar and chain in an attempt to make the chain saw cut. It’s also possible that there isn’t enough bar and chain oil (tank empty, small oiler hole), or that the oil is of subpar quality and isn’t lubricating the chain.

Why is my chainsaw chain smoking?

To diagnose the issue and find a solution, you must first determine where the smoke is genuinely coming from. It’s possible that it’s coming from your engine; you may have a clogged air filter, condensed water in the chainsaw, or the engine is flooded. It’s also possible for the smoke to come from the chain and bar; you may have the wrong chain on, a dull chain, incorrect gauge depth, or blocked lubricating holes.

Why is there white smoke coming out of my chainsaw?

There are a number of causes for chainsaw smoke, but one of the main factors for white smoke is poor fuel quality or an improper oil-to-gasoline ratio. Your fuel needs to be of top quality and should be brand-new if you want to avoid this. If the fuel has any contaminants, check it and replace it right away. Additionally, study the user handbook to learn the ideal mixture of oil and gasoline, then add the correct amounts of each to prevent problems.
