For the first time the chainsaw Ural was released in 1935. In 2005 at the machine-building plant named after F.E. Dzerzhinsky in the city of Perm collected a 14 millionth copy of the legendary instrument. 80% of the felling in the country is still conducted with the use of the Ural motor saw. Simultaneously with the assembly line the model for small works on farms comes off - the Druzhba saw, but it is a class lower than the older brother.
Characteristics of a Soviet saw motor saw
Initially, the chainsaw Ural stood on the technical equipment of the army, and only in 1955 the plant switched to the production of logging products, giving the model the name Ural 2. The tool weighed 1, kg. At the same time, the engine power was, l. from. The saw blade turned to a right angle during work, which facilitates the work of the fellers. The chain was forcibly lubricated, in the rigging of the unit was a hydrocline.
A sample of the chainsaw Ural of the 1946 edition is exhibited in the Artillery Museum of St. Petersburg. In 1958, the instrument was awarded a gold medal at the Brussels Exhibition of Achievements.
The Soviet Union was in isolation, the created equipment was valued, distributed to the forestry enterprises according to the order. The same distribution system did not allow the private ownership of not only the chainsaw Ural, but Friendship, too.
Technical characteristics of the chainsaw Ural 2:
- engine two-stroke, single-cylinder;
- power - 5 liters. from.;
- a fuel tank - 1.6 l;
- tank for lubrication of the saw unit 4 l;
- length of the tire - 46 cm;
- chain, number of links - 64;
- Step of the link 04 inches;
- slot width mm.
An important condition for the long operation of the Ural chainsaw was its proper break-in. The engine was initially started at idle using an enriched fuel mixture. It was necessary to burn 4 full tanks of fuel. After 25 hours prescribed work in a sparing regime on the same enriched fuel mixture. After that, a working mixture of 20 liters of AI-72 gasoline was used, 1 liter of oil.
Modern Chainsaw Ural 2T Electron
The plant made some changes to the production of power saws, and a new name was assigned to the improved model. The saw is still in service with forest workers and in private use. On the failure-free operation of the instrument is evidence of the 1997 model of the model, put up for sale.
Chainsaw 2T Electron is created taking into account work under severe conditions at any time of the year. It is made of high-strength materials. It is allowed to operate the tool in an aggressive environment and at all temperatures in the street. Therefore, detailed step-by-step instructions are developed on how to repair complex mechanisms independently in the field.
Despite the existing system of vibration damping, the layout with the separation of nodes turned out to be stiff and the vibration at work is strong. In this regard, it is prescribed, wood fellers work with a saw not more than one and a half hours per day. This will prevent the development of occupational diseases associated with harmful working conditions.
Powerful chainsaw has one special property that makes you reconcile with the disadvantages of the mechanism. It easily conducts both transverse and longitudinal sawing. In addition, the tool is reliable, high handles allow you to not stoop, to work in full growth. On the other hand, having got acquainted with the imported, professional equipment, the specialists see the shortcomings of the native model:
- The engine works with increased gas generation, the waxer has to work in a gassed environment;
- is used in 2 times more enriched with oil mixture than on imported machines;
- maintenance of the saw requires experience and skill;
- fuel consumption increased;
- chain brake less.
This is not a complete list, in which the old technology is inferior to modern foreign models. The demand is supported by the low price of the Ural chainsaw. However, entrepreneurs prefer foreign technology. The plant announced the termination of the production of the chainsaw Ural 2E Electron in 2013. In the sale of the models come from the manufacturer's factory and now.
At the plant, a new model was developed, the Ural 70 chainsaw, but so far it has not entered production. There was a new model in the lightened version, saw the gasoline chain Ural BP-3650. Powerful saw is declared as portable household. In it there was an automatic stop of a chain at idling. The ergonomics changed, the weight of the instrument decreased, the cooling system was created.
Model specifications:
- producer Ural;
- engine power l. from.;
- length of the tire - 45 cm;
- Weight, kg.
The declared price of the saw blade model BP 3650 is 6 thousand rubles.
Chainsaw regulation and repair
Experts argue that every action that must be performed while operating the tool is detailed in the technical operation manual. One of the main points after the break-in is the tuning of all conjugate systems. And for this it is necessary to know the structure and operation of the mechanisms.
The saw consists of the main components:
- engine;
- clutch;
- frame with handles;
- saw unit;
- engine starting system.
Much in the work of the motor depends on the correct adjustment of the carburetor chainsaw Ural. From the factory, the tool must come with an accurate working configuration of the most important components. However, sometimes you have to fix the flaws. As for the carburetor, everything is different. Initially, it is adjusted for the enriched mixture used during the break-in of new equipment.
Adjustment of the carburetor chainsaw Ural necessarily be required in the transition from run-in mode to a normal fuel mixture. To do this, position the nozzles. There are three screws:
- low speed propeller screw;
- screw for high speed control;
- screw idling.
The rotation of the propeller screws regulates the throttle valve of the fuel-air ratio. But at the same time this action changes the power and speed of rotation of the chain. When adjusting the tachometer, the conformity of the revolutions to the passport is checked. There is also an obvious way. On a poor mixture, the saw squeals, if the composition is rich - smoke comes from the muffler.
The engine system is designed to use AI-72 gasoline, but it is not produced. You can replace the fuel AI-93.
