Informational support

The list of advantages of the brand’s model range includes a large selection of models with different power and technical equipment. The official website of the manufacturer provides detailed information on the products and features of gasoline and electric saws, the production of which is mastered in the near future.

The relatively low service life of Chinese chain saws of different categories is compensated by the increased power of the drive, simplicity of design, standardization of spare parts and other consumables.

Operational properties

Soyuz chain saw

Inexpensive and economical in the enterprise, chainsaws “Soyuz” focus on a fairly wide range of sawing jobs.

Skills with the tools of this brand extend to:

  • Felling timber, firewood;
  • Trimming wood;
  • Construction and production of decorative wood elements for the yard and landscape design.

The performance of the more powerful and technically advanced models is as close as possible to the skills of semi-professional chainsaws.

The instruction manual included with the standard set has become more informative, so that owners can install the fuel equipment, set up the saw headset and make simple repairs to the equipment at home with their own hands.

Despite their cheap price range, Soyuz chainsaws are equipped with complete systems for quick starting, fail-safe ignition, perfect air purging and safe operation. Most notably:

  • Emergency stop mechanism actuation time has been reduced to 0.12 seconds to meet current standards;
  • Measures have been taken to extend the life of the engine, saw system and other components, which operate in difficult conditions with high temperatures, static and dynamic loads.
  • The carburetor adjustment was significantly simplified, and access to the chain tensioning mechanism became more convenient.

When developing the latest versions of the series numerous reviews and wishes of the users who use “Soyuz” chain saws in different regions of the country were taken into account.

Setting the carburetor

The regular “Soyuz” chain saw carburetor provides the optimal quality of gasoline-air emulsion, supplied to the engine cylinder, and stability of traction parameters at all operating modes. With a little skill the tuning of the carburetor can be done by the owner of the saw himself.

The main criteria for a correctly tuned fuel supply are quick RPM, stable idle speed, no smoke from the muffler and no knocking in the engine cylinder.

Setting the saw chain tension

It is strictly forbidden to operate the chainsaw or its electric-driven counterpart with the chain glued or broken. In the first case, it is not excluded from its exit from the hoop and the creation of a traumatic moment. Because of the excessive tension, there is intense jamming of both the chain itself and the guide bar.

The availability of light starting system and booster pump allowed adapting this model for full-fledged operation in the northern regions of the country. Durability of the power unit was increased due to application of wear-resistant chrome-nickel coating on the inner diameter of the cylinder and parts of the permanent connecting rod piston group.

The semi-professional class of the tool has a positive effect on working comfort, complaints of vibration and noise have been greatly reduced.

An overview of the electric-powered union

  • Compact size and less bulky;
  • no problems with winter starting;
  • simple design;
  • improved maintainability and cost-effectiveness.

Owners reviews

After a small test of all systems and suitable suspension Union went to work. I have two years incomplete without any problems.

The machine is not particularly satisfied with the quality of units and assemblies, but justifies the money invested in the purchase after careful refinement. Kirill Vasilievich

What they write on forums: Reviews of owners of Soyuz chainsaws

Anton Matzkevich, 38 years old, Smolensk region:

Chainsaw Soyuz PTS-99520T was bought at the end of 2016. For such a price was ready for the disadvantages, but they turned out not so much: the plastic is not very high quality and a lot of noise. The noise is understandable – quite a powerful motor. I do not use the saw that often – mainly for logging and sawing firewood. So far it has never failed me. Trees, cut down with the roots and with the diameter of 50-55 centimeters – it saws perfectly. The device starts up very easily and in any weather. I would like to note the successful construction of the starter.

Ivan Shestakov, 36, Altai Territory:

After buying a chainsaw Soyuz PTS-99520T I had to sweat a lot to remember it. The saw is not assembled very well – half of the bolts and screws are not tightened, parts are loose. After I filled up the fuel tank I realized that it was leaking and had to be repaired. When I worked, the saw vibrated a lot and made some noise, but later it seemed to work. In general, I got a totally compatible device with a powerful motor and a very low cost. I don’t use it much, so I don’t know how it will do in an intensive mode.

Advantages: Inexpensive, powerful motor, starter motor, again – the price;

Disadvantages: poor build, leaky tank, I often have to adjust the carburetor.
