Reviews about the chainsaw Soyuz

The smallest chainsaws – amateur, they endure only 40 minutes a day of periodic use. Often the power of such devices does not exceed 2 kW. In such units – low-profile chains, which significantly reduce the level of vibration at work. But the productivity of such chains is very low. But you can count on the insignificant weight, as well as ease of operation. The operator does not strain his hands and can prepare firewood, perform minor construction work and trim trees. For a private house or a private home where repair work is done only occasionally, a chainsaw of this class will be the best solution.

The Russian chainsaws described in the article are also available for sale as semi-professional models. They can withstand construction work, have sufficient power and can be used for the forest role. The only disadvantage is the lack of ability to use the devices for a long time. If you watch for 10 hours in a row every day, the tool will not withstand long work. The power of such units varies from 2 to 3 kW.

However, mostly chainsaws of the semi-professional class are on sale, the power of which is 2.5 kW. At the same time, the device is able to handle a trunk, the diameter of which does not exceed 40 cm. You can assess the convenience of working with such a chainsaw, knowing that its weight on average is about 6 kg.

Technical characteristics

The operational possibilities of this model are expanded by equipping the chainsaw 3.5 with a powerful power unit with a working volume of 45 cm3. The compact two-stroke ice works on a standard gasoline-oil fuel mixture.

Its design benefits include

  • High torque adaptation to variable loads;
  • availability of an easy-start system and an assisted start system, which is best suited to the economical carburetor output;
  • low noise level, in the range of 110 dB;
  • longer service life due to wear-resistant coatings on the cylinder face and friction parts.

Fuel and oil for the Soyuz chainsaw

As mentioned above, the Soyuz chainsaw is equipped with a two-speed engine with forced air cooling function. The rubbing parts of such engines contain oil in the fuel mixture, which can be prepared at home. For this purpose the necessary amount of AI92-95 gasoline is poured into a measuring tank and engine oil is added in a certain ratio. The oil/gasoline ratio for the Chinese chainsaw engine is 1/25. It is necessary to work out a tank or two of such a mixture at idling speed with periodic ngazovalka for 20-30 seconds.

Important: Before starting the engine, you must set the sawmill, also it is forbidden to run the engine only at idle speed – this can lead to a decrease in its power and a considerable reduction in its service life.

After running the engine, switch to a 1/50 fuel mixture and make several fillings in a smooth mode, without overheating or overloading the Union.

List of recommended engine oils for the Union chainsaw:

  • Union MSS-0104B;
  • storm om0201b;
  • ZMD-2-M Standard ZMD;
  • Echo Jaso FD with donor;
  • Husqvarna HP.

Your power tiller is equipped with an automatic sawmill lubrication system that requires high quality oil. Don’t skimp and don’t pour different surrogates into the tank and work some more.

Recommended chain oils:

  • ZMP M-Expert Bison;
  • Echo Premium B&C;
  • Husqvarna Chain Oil;
  • Oleo-mac Polar Lubricant;
  • Stihl Forestplus.

A powerful drive unit allows you to take advantage of the performance advantages of the detachable equipment. The 450 mm bar length is long enough to cut large diameter wood. Longevity of the bar and saw chain is ensured by automatic supply of special oil to the working area.

Precise dosage of the working fluid, taking into account the engine speed, is created by the oil pump with adjustable capacity. The complexity of the design is balanced by the availability of 50% oil for the sparking chain, which is an extension of the life of the saw set.

Chainsaw Starter Repair

The chainsaw starter can be repaired yourself by unscrewing the 3 cover screws. For this purpose, the spark plug wrench included in the kit is ideal. The starter is removed, then one screw of the mechanism is unscrewed, the coil of the starter and soft starter is removed. The mechanism is removed, as is the cable winding spool. For repair, prepare a cable of suitable diameter, which length should be 1.3 m. Tie a knot at one end, and then pass the line through the hole in the spool. It is not necessary to wrap the cable.

If the chainsaw starter is repaired, the next step is to install the spool in place, the groove must get into the seam of the spiral spring. It is important to check by turning the coil clockwise that it is restored. In the next step, the soft starter mechanism can be installed, with the edge fitting into the spiral of the coil. A screw with a washer is screwed, and after the second end of the cable is inserted into the outlet hole.

advantages and disadvantages

Despite the budget price, the union of the model PTS-99520T is equipped with modern systems that provide confident, economical consumption of fuel, comfortable and safe working conditions.

In a small list of design and operational shortcomings:

  • moderate quality of assemblies and circuits;
  • large, relative to similar analogues, weight;
  • There are justified claims to the quality of assembly.

Owners reviews

I am the only owner of a chainsaw Soyuz PTS-99520T in the whole county, so I had to single-handedly bring the tool to a normal level. Powerful and thought-out machine assembled effortlessly, the carburetor is not set correctly, the quality of the regular saw chain leaves much to be desired. By putting in screw mounts, tuning the fuel system and replacing the headset with a stylus, the saw was 100% ready to go. There were no problems with sawing dense and frozen wood. To the surprise of my neighbors, I cut down a tree with a diameter of about 400 mm in one go. Particularly liked the engine, when working with a low octane number traction is reduced slightly, even at high load detonation noise is virtually absent. Kirill

On closer examination, it turned out that bought with the hands of a second-hand soybean chainsaw is of Chinese origin. On the recommendation of a good acquaintance, I gave the machine, purchased for half price, to be reworked in a service shop. For 600 rubles from a half-finished product made an excellent tool for its value, I still had to pay specifically for the installation of a branded chain. Sergey Petrovich

Product operation

Lubrication of the saw chain is automatic. The pump regulates the dosage depending on the type and intensity of work. To extend the life of the device, it is important to consider the rules of operation:

  • Read the instructions before using it for the first time.
  • To avoid injury, regularly clean the work area of dirt and choose well-lit areas for mowing.
  • Do not use the device in areas with explosive materials.
  • Use protective clothing;
  • Check that the device is working properly before switching it on.
  • It is better to have repairs done in a special repair shop;
  • Release accumulated gasoline fumes when refueling;
  • Do not touch the surface when sawing to avoid a hiccup;
  • Hold the saw securely with both hands;
  • Saw at maximum speed;
  • Do not lift unit above shoulder height.

Self-service includes sharpening the chain mechanism and repairing the saw starter.

The file for sharpening is chosen depending on the division of the chain (4-5.5 mm). Some kits contain a special round file. It should be at right angles to the vertical level of the chain.

In Internet sources, you can often find mono information that “Soyuz-99371” refers to the category of semi-professional saws. Perhaps this is due to the powerful motor and the medium-length bar, the versatility of which allows it to perform a variety of works. But make no mistake: the Union is just a budget saw, and recordings showing a professional forester turning over a hectare of forest with this tool are most likely a fake.

The division of saws into classes is not at all about size and performance, although these parameters also affect the price segment and application area. It is a question of reliability and protection, which have all the nodes and units. And in this sense we have to say honestly: the Union loses not only against Calm, Husqvarna or Makita, but also against its more reliable Chinese brothers like partners or champion.

With very moderate use, “straight” hands and a certain amount of luck the saw can work in the village for two or three years. More – this is a rarity.

Overview of the range of electric saws Union. Technical characteristics, service and the opinion of experienced users

  • simplicity of the device;
  • no problems with starting the electric saw;
  • high maintainability; economy of easy maintenance;
  • eco-friendliness of electric tools;
  • compact size and low weight.

instruction for use and maintenance

Soyuz electric saw at work

When operating the saw, the safety instructions for the power tool must be strictly followed:

  • The saw can only cut wood and wooden objects.
  • It is strictly forbidden to work with the saw in wet and rainy weather.
  • Since sawing wood is dangerous work, it is necessary to strictly follow the special recommendations, to master certain skills.
  • The saw can be removed from the tree only with the help of a moving chain.
  • It is necessary to use the center of gravity of the saw when sawing workpieces.
  • I have never sawed the end of the bar to avoid rebounding.
  • For optimum chain tensioning, use a cross bar and turn the tensioning screw clockwise. Keep in mind that the chain will increase in size as it heats up and may slip off the drive link.
  • Because the chainsaw is highly stressed, check the oil level in the oil tank before each use – the oil level window must be completely closed.
  • Check the sharpness of the saw systematically.
  • For even wear of the bar, flip it over after each time you tension the saw chain.

Main malfunctions, repair methods

To avoid malfunctions and breaks the manufacturer recommends timely maintenance of the saw and use of high-quality oil. If the breakdown could not be avoided, you can try to fix the arisen small problems. In the case of serious breakdowns, you should contact the professionals.


  • If the saw does not work, check the condition of the cables, plugs, sockets and the presence of voltage in the network. The carbon brushes may have worn out or the brake may be on.
  • The chain will not move when the motor is running – the chain brake is loose.
  • Chain overheating may be caused by insufficient lubrication.
  • Poor saw quality – Check chain sharpening, tensioning, and proper saw system installation.
  • If the saw works hard, adjust the tension.

Owners identify some disadvantages of “Soyuz” electric saws: poor quality plastic housing, fairly short life of the saw system, unreliable pulling of the string strength.
