7 Common Husqvarna T435 Problems & How To Fix [Detailed Guide]

Here I am going to discuss in detail the 7 common problems of the Husqvarna T435 chainsaw and how to fix them quickly. Apart from these, there are other problems you can find with these chainsaws, but they are not seen frequently.

Problem 1: Chain Coming Off The Bar Or Keeps Loosening

The chain coming off the guide bar repeatedly while working is annoying and a waste of time. Many times, this type of incident can be dangerous and lead to accidents. If the chain protrudes over 1/2 inch from the guide bar after pulling, you know it is loose.

Chain Coming Off The Bar Or Keeps Loosening


Excessive dirt accumulation, wear, or loss of proper shape on the chain and guide bars are among the causes of this problem. This problem can also occur if there is a problem with the tension screw.

How To Fix:

There are several steps you need to take to resolve this issue. Clean the grooves of the chain and guide bar thoroughly to ensure that there is no dirt. Tighten the chain as required. If there is a problem with the shape of the guide bar, try to repair it. Replace if not possible.

Check if the tension screw is ok. Replace if there is any wear or stripping problem. Ensure a required level of lubrication by adjusting the oiler.

Problem 2: Blue Smoke After Starting

If you notice excessive blue smoke coming out of the chainsaw after starting it, you may be feeling upset. Several Husqvarna T435 users have reported facing these types of issues.

Blue Smoke After Starting


Usually, excess fuel in the carburetor can cause excess blue smoke to come out of the chainsaw at startup. The accumulation of dirt in the air filter is also one cause of this problem.

How To Fix:

To solve this problem, you need to pay more attention to carburetor maintenance. Clean the carburetor thoroughly and remove any excess fuel. Clean the air filter, and replace it if possible.

Problem 3: Kickback

You must not expect unexpected upward motion or kickback of the guide bar when cutting wood. However, the Husqvarna T435 chainsaw has a bad reputation for kickback. It can also lead to accidents at any time.

Kickback Problem


Basically, kickback problems occur when the oiler is not working properly or the chain and guide bar are not lubricated properly. Sometimes you can face this kind of problem even if the chain is dull.

How To Fix:

To solve kickback problems, you need to make sure the guide bar and chain is lubricated by adjusting the chainsaw’s oiler. You can easily adjust the oiler using just a flathead screwdriver. T435 models have a screw on the bottom for oiler adjustment. Rotate the screw counterclockwise to increase the oil flow.

If this does not increase oil flow, you may need to disassemble and clean the oiler and reassemble it. In that case, the video below can help you.

Problem 4: Carburetor Issue

The carburetor plays an important role in keeping a chainsaw running smoothly. It controls the ratio of very tiny amounts of fuel and air entering the engine. If there is a problem with the carburetor, the chainsaw will not run smoothly, the engine will bog down under load, turn off at idle, and have trouble starting.

Carburetor Issue


Dirt or not using the correct ratio of fuel and oil mixture is the major causes of carburetor problems. Also, low-quality fuel and oil are responsible for causing carburetor problems.

How To Fix:

Pay attention to carburetor cleaning and maintenance. If the problem persists after using clean, quality fuel, you may need to replace it.

Problem 5: Difficult Starting

Difficulty starting the chainsaw at the beginning of the work will spoil the interest in the work. This is quite annoying and this type of problem is more common when chainsaws are old.

Difficult Starting


This problem can occur due to many reasons, including problems with a spark plug and ignition module, dirty air filter, and carburetor problems among others. Low-quality fuel can also be responsible for this problem at times.

How To Fix:

Clean the spark plug and air filter thoroughly. Clean the carburetor and adjust it properly. Check the ignition module, and fix it if there is any problem. Above all, be careful with maintenance to keep the chainsaw running smoothly to avoid these types of problems. Be sure to use quality fuel and oil in the correct ratio.

Problem 6: Idling Issue

You may have noticed that some chainsaws stop when idling. In some cases, the chainsaw is running at high rpm even at idle. In both situations, the matter is not convenient. While frequent stops are annoying, running at high RPMs is also a waste of fuel.

Idling Issue


This problem can occur if the carburetor is not adjusted. On the other hand, you can face this problem even if you do not use the fuel and oil mixture as per the correct ratio.

How To Fix:

Clean the carburetor thoroughly and adjust its low-speed screw. This screw determines the RPM of the chainsaw’s engine at idle. Besides, you must use standard fuel and oil mixtures according to the company’s prescribed ratio.

Problem 7: Overheating

Overheating of chainsaws is one of the major obstacles to uninterrupted operation. However, many users report overheating problems with Husqvarna T435 chainsaws.

Overheating Issue


There can be many reasons for a chainsaw overheating. Among these, wrong oil and fuel mixtures, and a blocked or clogged exhaust are the most common reasons.

How To Fix:

You must use the correct fuel and oil mixture. Clean the exhaust system if it is blocked by dirt. You may need to make muffler modifications if necessary.
