Description of the Husqvarna 240 petrol chainsaw

The Husqvarna 240 petrol chainsaw is a semi-professional sawing tool intended primarily for private use. It is used for cutting tree branches, tree crowns, harvesting fuel and sawing logs and planks. It can be used in the private sector as well as for urban work, in forestry and on construction sites. The chainsaw design is robust and easy to maintain, and it is able to withstand heavy operating loads.

The Husqvarna 240 chainsaw weighs 4.7 kg without the guide and chain. It is powered by a 2.04 hp two-stroke engine with X-Torq carburetor, which not only reduces the amount of harmful emissions but also increases the unit’s performance. The engine is started manually by an inertia starter and has a built-in easy-start system.

The throttle control is combined and the ignition system is contactless, with an upgraded carburetor. For increased comfort of work, a vibration damping system (with special fasteners on the handles) is installed. The chain tensioner is attached to the side of the device and guides with a length of 33 to 40 cm can be used. For added user safety, the chainsaw has a chain brake and hand guard. The saw chain is automatically lubricated.

Along with the chainsaw, the kit includes:

  • Tires;
  • Chain;
  • Oil in a container.

A protective cover can be purchased separately.

Prepare chainsaw for work

Before commissioning, the tool must be properly prepared:

  1. The chainsaw is assembled into a single structure.
  2. The headset is mounted and the saw chain is tensioned.
  3. The saw is filled with oil and a ready-made fuel mixture.
  4. The tool will start. as described in the manual.
  5. The function of the braking system is checked immediately.
  6. Control of the oil flow to the chain.
  7. The idle speed is set.

The saw is started, all systems are involved and working – it remains to retract the chainsaw. And the video will tell and show how to properly start the Husqvarna 240 chainsaw.


The break-in period for the chainsaw is about 10 hours. During this phase, the device should be operated in gentle mode without subjecting it to increased stress.

The aim of breaking in is to optimally coordinate all moving parts of the chainsaw. If you skip this process and load the chainsaw to its maximum from the start, the risk of piston binding increases significantly. This can lead to engine damage.

How to properly prepare the fuel mixture

To create a flammable mixture, the manufacturer recommends taking:

  • High-quality gasoline with an octane number of at least 90 and no more than 93;
  • Original Husqvarna XNUMX-stroke engine oil.

The ratio of petrol to the original two-stroke oil is 50/1 (that is approx. 2%), when using engine oils from other manufacturers (oil of the JASO FB / ISO EGB class is permissible) the ratio is approx. 3% – 33/1.

The use of original chain oil with a special viscosity is recommended as a lubricant for the chain.

Servicing the Husqvarna 240 chainsaw

In order to ensure a long service life of the chain saw, the owner of the machine must carry out regular maintenance work, which is limited to the following:

  • Filling with fuel and oil;
  • Chain sharpening;
  • Cleaning the tool from dirt;
  • Air filter maintenance;
  • Spark plug service
  • Carburetor adjustment;
  • Checking the condition of the braking system;
  • Cleaning of oil passages;

New owners of devices ask the following questions:

  • How to remove a carburetor from a Husqvarna 240 chainsaw;
  • How to adjust the carburetor on a husqvarna 240 chainsaw yourself.

carburetor adjustment

After breaking in, some chainsaw owners adjust the carburetor. It consists of several stages:

  1. Start the saw, turn the high and low speed adjustment screws until they stop. turn back 1.5 turns;
  2. Warm up the saw for about 10 minutes. Adjust the idle speed with the idle screw. With the correct settings, the chain will not move on the bar when idling;
  3. Check the saw for acceleration. When you press the gas pedal, the speed should increase quickly.

We offer you to watch a video showing how to disassemble and assemble the Husqvarna 240 chainsaw.

Owner Feedback

Thomas Schneider, 33 years old:

I purchased the 240 model in 2014. The saw is excellent. It started without any problems and the running-in process also went smoothly. I use them for tending the garden, and the branches I cut off serve as fuel for the sauna. The tool is lightweight, powerful and works flawlessly. I changed the filters and replaced the starter a year ago – everything still works great. I am very happy with the purchase.

Advantages: light, powerful, durable. Disadvantages: none noted.

Maria Müller, 40 years old:

I’ve read a lot of praise for Husqvarna and I’m confused: either I got a fake from China and everything is abysmal, or the reviews are rigged. The saw is difficult to start, you almost lose hope, then suddenly you want to work with it… Everything wobbles and has play… the chain cuts badly, everything falls apart, the parts don’t fit even though they should be original!

Positive: found nothing, everything is bad. Cons: Falling apart, won’t start. Parts don’t fit.

Johann Schmidt, 46 years old:

I use the chainsaw almost every day. My Husqvarna is now 2.5 years old. I earn my living with it – I saw firewood for neighbors, cut branches and trees and even had to demolish buildings with it a couple of times. The tool cuts great, starts easily and when I noticed it was starting to overheat I replaced the spark arrestor and everything worked again. Of course, the cable broke off, but overall I’m happy with the chainsaw.

Advantages: powerful, light, repairable, handy. Disadvantages: none noted.
