The device chain saws and the principle of operation

Among the entire range of chainsaws can be identified as follows: with electric drive and engine running on gasoline. Considering the device chain saw, it can be distinguished the following main elements:

• housing;
• electric motor;
• chain;
• guides tires;
• compartment for the oil pump and the oil itself;
• protective screen, chain brake lever;
• screw fastening tires and chain tension.

The case of an electric saw serves button panelthat control the inclusion and blocking of the tool. Also there is a comfortable grip and protective shield. Some differences are found in more modern and improved models, in which a special handle can be found that allows you to control the degree of chain tension.

This tool works as follows: the first action is engine starting, as a result, a torque is generated that spreads to the gearbox, sprocket and chain, and this leads to the rotation of these elements, thereby starting the cutting process.

Consider that a chain equipped with cutting edges has wide width compared to a fixed tire, while the tool is running, the risk of jamming in the material being processed is excluded.

In the process of cutting electric saw on the cutting surface of the chain from the container in the case, the oil enters what provides its lubrication.

Acquainted with the principle of operation of an electric chain saw, you can proceed to the consideration of the main parameters that must be considered when choosing this tool.

The first thing I would like to begin to consider the chain electric saws - the companies that produce them. This point should be paid special attention, because it directly affects the quality of the selected tool.

To date most famous have received electric chainsaws offered by the following companies:

1. PATRIOT.
2. BOSCH.
3. SPARKY and many others.

Choosing a power saw of any of the above brands, the consumer can be sure of high quality products and its reliability. However, the sale can be found models and other brands that, despite the lesser fame, still worthy of attention because of their compliance with European standards.

First of all, they are able to attract the attention of the consumer thanks to more affordable price. The most prominent representatives of this list are such companies:

• Interskol.
• EFCO.
• STRONG.
• Zenith.

In the light of the above, it can be concluded that today such a tool as a chain power saw is available to almost every consumer, regardless of the level of his wealth.

If you are interested in a model of lesser-known manufacturers, keep in mind that by acquiring such an aggregate, you get a tool that will have not quite attractive properties. For example, some saws can be quite cumbersome, others have a plastic surface, due to which it will not be very convenient to work with such a tool.

In addition, these products are not all right may be with ergonomics. The products of some manufacturers may altogether do not provide for service.

For this reason, it is recommended to consider products from reputable manufacturers if you want to purchase a tool for frequent use. And do not be afraid of the higher price of such products, because all this will be offset by high quality saws.

Having decided on what type of power saw is more suitable for you, you can proceed to the consideration of technical characteristics.

In that case, if you are interested in the model, so that with its help it was possible to prune garden trees, then you can limit yourself to an aggregate with lower power parameter.

In the first case, it is recommended to consider models whose power rating ranges from 2.5 to 4 kW. In this case we are talking about professional toolused in industrial plants for harvesting wood.

But for those who need a power saw, which will be convenient to work in the country, you should choose units with a capacity of 1.5 to 2 kW. These indicators correspond to the model of electric chainsaws for domestic use.

If you follow the recommendations of experts, it is advisable to stop the choice on models of electric saws, which have a small power reserve. An alternative here is the option of sharing a tool with special voltage regulator.

The need for this is due to the fact that often where there are summer cottages, there is a voltage mismatch with accepted standards. In addition, from time to time in such territories it is observed to decrease.

In the event of such situations, certain changes occur in the operation of the engine, which results in an increase in the current strength in order to compensate for the decrease in voltage. However, such situations do not benefit the engine, which is why its resource decreases.

Features of the location of the engine

If the saw is needed to cut vertically, then it is best to choose a model that has lateral arrangement of the motor.

Such a unit will be the most suitable tool for cutting wood at an angle of 90 degrees from top to bottom.

If we consider this parameter, we can distinguish two options:

• the first involves the placement of the power unit across the body;
• the second is the placement parallel to the motor.

On sale there are many models in which disturbed balancing, because of what work such a chainsaw will not be so easy. There is no guarantee that by placing the instrument in a different position, it is possible to achieve improved conditions for the operation. Say, difficulties can arise if you need to trim the branches of a tree at an angle above head level.

More preferable in this plan are electric saws, which provide longitudinal engine placement. Such saws can be used to perform almost all types of work. Naturally, such versatility determines the high cost of such tools.

However, this does not prevent them from remaining in demand in the market. A similar device has correct balancingtherefore, having placed it in any plane and at the required angle, the owner will not experience problems in solving many problems.

In this regard, even before buying an electric tool, you should decide for what tasks you acquire it.

In that case, if you only need an electric chain saw for cutting wooden building materials, then you should not choose a unit with a longitudinal position of the electric motor, which, in addition to everything, will cost more than other models with similar capabilities.

When the issue with the manufacturer, power and location of the engine is resolved, you can consider other characteristics.

If you have to deal with thick trees, then it is best to give preference to the unit, which the tire is long.

If an electric chain saw is purchased for trimming trees in the garden or sawing wood, then you can stop the choice on the tool with minimum tire length. Most often, a saw, which has a tire length of about 30-40 cm, can perfectly cope with such tasks.

Chain brake

When working with an electric saw, the owner may encounter such a phenomenon as a kickback, which occurs as a result of the contact of the working part with a material of high hardness. All this leads to the fact that the power saw leans sharply to the side location of the worker with an upward offset.

All this creates the risk of injury to the hands of the worker. To avoid negative consequences, manufacturers use a special adaptation - chain brake.

In its performance, it looks like a lever, having the appearance of a disk, which is located directly in front of the handle. During the return strike, the worker, unwittingly, displaces his left hand mechanically to this lever, and this leads to turn off the motor. In practice, all this happens in a very short time - about 0.1 seconds.

Power lock function

This addition is implemented in the power tool in the form of a button, which is located on the body. Its presence allows you to be sure that nothing will threaten health during the operation of the electrical system.

Considering that a power tool can cause serious harm to human life and health, then each manufacturer must install a lock button on their product, in order to guarantee safety working person.

If you neglect it, it can lead to the following consequences. At the most unexpected moment, the saw may turn on, and this will already create a risk of serious injury.

According to experts, should refuse to purchase power tools that are not equipped with a similar element. If the saw does not have a lock button - this is a clear sign of a violation of production technology, or you are being offered a fake.

Electric chain saw is a popular tool among summer residents. To make it really a reliable assistant and noticeably simplify the execution of many works, it is necessary to choose the right tool.

First of all, deserve attention saw specifications, since it depends on them how effectively the tool will cope with the tasks assigned to it.

Also needed focus on security, as a power saw is a traumatic tool and can cause serious harm to human health if it does not provide special locking mechanisms.
