1. The Chain won’t stay in place

One of the most common issues that Husqvarna T435 chainsaw users face is the chain not staying in place.

There can be several reasons behind this problem, such as a worn or loose chain tensioner, a damaged chain, a worn sprocket, or a bar.

The solution to this problem depends on the cause. If the chain tensioner is worn or loose, you need to check the tensioner and adjust it according to the manufacturer’s instructions.

If the chain is damaged or worn, you need to replace it along with the bar. And if the sprocket or bar is worn, you need to replace the worn parts with new ones.

2. Chainsaw won’t start

Another common problem that you may encounter with your Husqvarna T435 chainsaw is that it won’t start. This can be frustrating, especially if you need to use the chainsaw urgently.

There are several reasons why your chainsaw may not start, such as fuel issues, a faulty spark plug, a carburetor, or an air filter.

To troubleshoot this problem, you need to first check the fuel quality. Make sure that you are using fresh gasoline that is mixed with the correct ratio of oil.

The fuel mixture ratio recommended by Husqvarna for the T435 chainsaw is 50:1. If the fuel is fine, check the spark plug. The spark plug should be clean and gapped correctly.

If the spark plug is dirty or damaged, replace it with a new one. Another common cause of a chainsaw not starting is a clogged carburetor or air filter.

To fix this issue, clean the carburetor and air filter, and replace them if they are severely clogged.

3. Chainsaw stalls while in use

If your Husqvarna T435 chainsaw starts but stalls while you’re using it, it can be due to several reasons such as the carburetor or fuel issues, a clogged air filter, or a faulty ignition module.

To fix this issue, first, check the carburetor and adjust it according to the manufacturer’s instructions.

If the carburetor is fine, check the fuel quality and replace it if necessary. If the fuel and carburetor are fine, check the air filter, and clean or replace it if it is clogged.

If none of the above solutions work, there may be an issue with the ignition module, and you may need to replace it.

4. Chainsaw lacks power

If you notice that your Husqvarna T435 chainsaw is not performing as well as it used to, it may be lacking power.

This issue can be caused by several reasons such as a clogged air filter, a faulty spark plug, or fuel issues.

To fix this issue, first, clean or replace the air filter. If the air filter is fine, check the spark plug, and replace it if it is dirty or damaged. Check the fuel quality if the spark plug is fine, and replace it if necessary.

5. Chainsaw overheats

Although rare, your Husqvarna T435 chainsaw may overheat.

This can be due to several reasons such as a clogged air filter, the fuel mixture being incorrect, or using the wrong type of oil.

To fix this issue, clean or replace the air filter, use the recommended fuel mixture, and use the recommended oil.

6. Chainsaw leaks oil

If you notice that your Husqvarna T435 chainsaw is leaking oil, it can be due to several reasons such as damaged oil seals, a worn oil pump, or an oil tank cap that is not sealing properly.

To fix this issue, replace the damaged oil seals, oil pump, or oil tank cap.

7. Chainsaw produces excessive vibrations

If your Husqvarna T435 chainsaw produces excessive vibrations, it can be due to several reasons such as damaged or worn guide bar, chain, or engine mounts.

To fix this issue, replace the damaged or worn guide bar, chain, or engine mounts.
