Husqvarna chainsaw device
All chainsaws from this company differ in technical characteristics, but are similar in structure. The main parts of the structure that should be paid attention to include:
- Saw body;
- Engine;
- Chain and bar;
- Handles.
The Husqvarna company uses two-stroke engines in its devices. Their ignition system is electronic. A distinctive feature is the carburetor, which allows you to use the saw in any position.

When creating the case, shockproof plastic is used, which is excellent for harsh winters, as it can withstand very low temperatures. Husqvarna saws also have two handles, one of which is made of durable plastic and aluminum material. It is attached to the main body using self-tapping screws. The second handle is firmly attached with shock absorbers.
Over the years, Husqvarna has created a number of features that make their saws special. These include:
- Air Injection. Thanks to this function, it became possible to increase the operating time of the saw by pre-filtering the incoming air. This eliminates the need for constant filter maintenance. This is due to the fact that less debris reaches the filter.
- Pump. This company was one of the first to put into operation oil pumps that supplied lubricant to the chain. This made it possible to significantly save lubricants and increase the operating time of the chainsaw.
- Smart Start. The system is designed to reduce resistance when starting the saw. Husqvarna engineers were able to reduce this figure by almost half by adding a spring to the design, which helps rotate the flywheel.
- Removable filter. The air purifying filter can be pulled out and cleaned or replaced in a few seconds. This design was invented a long time ago, but at one time it made a big breakthrough in the history of chainsaws.
- X-Torq is a technology that has reduced fuel consumption and increased the environmental friendliness of the device. It is patented by Husqvarna and cannot be used on devices of other brands.
- Fixed nuts. A small innovation in the design of saws that will eliminate the eternal problem of lost nuts.
Pros and cons of using
Any chainsaw has both positive and negative aspects associated with its operation, maintenance and repair. Husqvarna 236 is no exception. According to real users of this saw, it cuts perfectly, but does not start very well.
Service center experts claim that the Husqvarna 236 is very capricious in maintenance and repair. This is especially true for the carburetor, the design of which is slightly different from that installed on previous Husqvarna models.
The 236 is equipped with a Zama carburetor with an accelerator pump, which, if stored incorrectly, quickly breaks down.
The Zama carburetor is installed on Husqvarna 236 chainsaws
The problem can be solved by replacing the o-ring, which is installed on the pump piston. Repair kits that contain accelerator pump rubber bands are quite rare on sale and for this reason you have to replace the carburetor completely, which greatly increases the cost of repairs.
The assembly of the Husqvarna model 236 chainsaw is of very high quality, the body parts fit well, there are minimal gaps between them, but the structure of the saw is very inconvenient. For example, in order to remove the carburetor, you need to unscrew several screws, remove the control lever and unscrew the rear handle.
Operating instructions for Husqvarna chainsaws
If you use the saw incorrectly, it will begin to break and stop performing its functions. In order for a chainsaw to serve without any complaints, you need to know the rules for using it.
First, you should properly prepare the chainsaw for work. The chain must be well tensioned and must not come into contact with other parts of the device. Then you need to pull the lever, but only if the engine is completely cold, and put your foot in the rear handle. Then pull the cord until the saw starts
What kind of gasoline should I put in my Husqvarna chainsaw?
You cannot use old gasoline for Husqvarna chainsaws. When using stale fuel, tool parts may quickly wear out and engine power will decrease.
Also, all instructions for saws talk about the dangers of 95 and 98 octane gasoline for the device. Since all Husqvarna chainsaw models run on two-stroke engines, only 92 gasoline is suitable for them. Otherwise, detonation will begin in the engine.
How to properly fill gasoline into a Huksvarna chainsaw
The cleanliness of the fuel also affects the operating time. If there are foreign impurities, debris or rust in gasoline, it is necessary to strain it through thin gauze.
Which oil is suitable for a Husqvarna chainsaw?
Gasoline alone is not enough for Husqvarna saws to operate smoothly. You will need a mixture that will include:
- Petrol
- Chain oil
- Two-stroke oil
- Filter oil
The Husqvarna company has created its own oil for chainsaws. It is only suitable for two-stroke engines. It does not dissolve well in liquid. It is noted that this particular oil is suitable for cold temperatures. Typically, oil is sold in black cans, on the back of which there is a detailed recipe for the fuel mixture for saws.
Which oil is suitable for a Husqvarna chainsaw?
For the chain, it is better to use Vegoil oil, which has low consumption and is resistant to frost.
Air filter oil is highly effective at capturing excess particles in chainsaw filters. It prevents debris from entering the engine combustion chamber.
Of course, you can use other oils, but Husqvarna chainsaw manufacturers recommend using their own brand of fuel.
The ratio of gasoline and oil for a Husqvarna chainsaw
To prepare the fuel mixture, you need to mix little and gasoline in strict proportions. So, for conventional saws, up to 50 milliliters of oil are taken per liter of gasoline. However, in the case of Husqvarna chainsaws, it is recommended to mix 4 liters of gasoline and 100 milliliters of oil.
It is better to prepare the mixture in special measuring canisters. They have two holes into which gasoline and oil are poured. This mixture can be stored for no more than a month. Using older fuel will cause the chainsaw to malfunction.
Run-in
Before starting work, each saw needs a break-in so that individual parts of the engine can break in. Also, running it in will help beginners better understand the principles of using the device.
To break in, you need to turn on the cyclic mode and the lightest load, and then saw for one minute. Then turn on idle for half a minute.
Important! It is strictly forbidden to turn on the idle speed first, as this may cause a malfunction of the spark plugs.
Sawing
To cut down a large tree, you need to determine which way it will fall. To do this, you need to count the number of branches and understand where the largest ones are directed. It is also important to pay attention to the tilt of the barrel and the direction of the air flow. Based on this information, you can understand where it is better to dump him.
sawing trees with a Huksvarna saw
After cutting down a tree, all branches must be cut off. To do this, it is better to stand on the left side of the trunk. It is better to work carefully and slowly, without touching the wood with the nose of the saw. First, cut off the upper branches, then go down below. Then you can start sawing the trunk itself. Unlike branches, the trunk is sawed from below, gradually rising to the top.
Important! When bucking crooked trees, you must not be below the trunk. And if the cutting part is stuck, then you need to turn off the engine, tilt the tree and free the chainsaw.
General rules of use
All instructions for chainsaws contain points that are recommended to be followed to avoid accidents. They look like this:
- Do not work with a poorly adjusted tool.
- Do not wrap the starter cord around your hand while starting the saw.
- It is advisable not to cut the tree trunk completely, but leave a few centimeters.
- When moving from one object to another, it is important to turn off the chainsaw engine.
- Adjust the device only with the engine turned off.
- Avoid felling trees on a steep slope or overhanging trees.
- It is forbidden for strangers to be within a radius of 50 meters from the tree that is going to be felled. The sawyer and his assistant can participate in the cutting.
- Pay close attention to where the tree is going to fall and adjust the side if necessary.
- It is strictly forbidden to use matches and lighters when refueling the chainsaw.
- If the chain breaks, you must immediately turn off the saw.
A chainsaw is a very dangerous device that requires not only experience in use, but also knowledge. If you use the tips given above, you will not have any problems during your work.

Typical faults and repairs of Husqvarna chainsaws
When purchasing a Husqvarna chainsaw, it is important to clarify what malfunctions are typical for it. You also need to figure out how to fix such problems. We'll look into this further.
How to adjust the carburetor on a Husqvarna chainsaw?
It is necessary to adjust the carburetor if:
- The engine starts with difficulty.
- The idle speed has increased.
- The revs do not increase and there is no traction.
- The tool smokes during operation.
To adjust the operation of the carburetor, you will need to prepare screwdrivers for screws, a tachometer, a Phillips screwdriver and a compressor for purging.
To begin, the chainsaw is set to factory settings, turned on and warmed up for two minutes. Then, using the rotation screw, you need to find the position in which the engine will operate at the highest speed. After this, the screw must be turned a quarter turn in the opposite direction and the power of the tool must be adjusted. To do this, you should connect the tachometer, press the gas and check the values on the tachometer. They can be adjusted using a screw. It is important to bring the values to those specified in the technical specifications.
How to remove the clutch on a Husqvarna chainsaw?
Chainsaws from different companies have their own nuances in repair. But the principle of removing the clutch remains the same for all tools.
The first step is to remove the chain brake cover. Afterwards, you need to unscrew the nuts a little, thereby reducing the tension in the chain. The nuts can be completely removed and the cover removed only after loosening. Next, the chain is removed and disassembled, and the entire device is cleared of debris. Then you need to fix the piston by first unscrewing the cylinder spark plug. To fix it, you need to rotate the crankshaft until the exhaust hole is clogged. You can stop the piston by placing a rope in the hole, which must be removed after the repair has been successfully completed. It is necessary to remove all the nuts on the clutch, disassemble the mechanism and check it for damage. Damaged and old parts should be replaced with new ones. Afterwards the mechanism is assembled in a mirror order.
Oil does not flow to the Husqvarna chainsaw chain - reasons and solution
Oil may reach the chain in insufficient quantities or not at all due to several reasons. They may be as follows:
- The filter is too dirty
- One of the pump parts is broken
- Contamination of fuel supply channels
- The chainsaw was filled with thick fuel. This problem usually appears during the cold season as the oil becomes thicker.
If the fuel supply channels are clogged, they must be thoroughly cleaned. It is also necessary to control the amount of oil in the tank. In some cases, it may be necessary to replace the pump or the tank itself.
Husqvarna chainsaw chain
To determine which parts need to be replaced, you need to completely disassemble the tool. For people who have not previously dealt with chainsaws, it is better to contact a workshop. Because even after self-repair, the problem may not go away. There is always a risk of incorrectly reassembling a repaired device.
