How to choose a chainsaw photo Modern chainsaw successfully combining such qualities as mobility, safety and convenience at work, durability, has become a valuable assistant in the garden. In this article, we will give advice on the correct choice of a chainsaw and teach you how to use it productively for your own purposes, while ensuring your own safety.

The modern market offers a wide range of different tools, but we can not say that their quality is always at the proper level. Low prices for Chinese-made tools are the reason for their popularity among buyers, providing high demand. However, it should always be remembered that the chainsaw is a source of increased danger. And the problem is not only, or more precisely, not so much that it can break down in the process of work, a much more serious consequence of such a breakdown may be injury to people. We hope that a reasonable consumer understands the absurdity of the situation when the price of such a complex instrument is equivalent to the price of several kilos of sausage. Therefore, we will not even discuss the low-price model of chainsaws and recommend the best online store with low prices.

The trade marks SOLO, STIHL, MAKITA, HUSQVARNA, DOLMAR,null, SHINDAIWA, ZENOAH,null, JONSERED, HITACHI, OLEO MAC and others, which produce tools for professional and domestic use, are widely known. Of these, you can choose a good chainsaw for cottages and houses. The leaders in this list can rightly be called well-known trademarks of STIHL, HUSQVARNA and JONSERED.The latter is a division of the company HUSQVARNA, specializing in the production of professional chainsaws. All these companies have a long history and many years of experience in producing high-quality chainsaws.

The German engineer Andreas Steele was the founder of STIHL for the first time in 1929 to create a two-handed chainsaw with a 6-horsepower engine, which at that time was in great demand. Since then, the company has carried out numerous developments, the results of which have been introduced into production( chains for saws, automatic lubrication of saws, centrifugal clutch, etc.).In addition, the company belongs to the authorship of the invention of a manual chain saw with a drive from a gasoline engine.

The Swedish company for the production of gasoline powered tools HUSQVARNA, the closest competitor of STIHL, is currently a recognized manufacturer of gasoline powered tools, including chainsaws. An interesting fact from the history of the firm: it was founded in 1689 and at that time was known as a manufacturer of weapons. Now professionals, choosing a gasoline-powered instrument, prefer products of the company HUSQVARNA.Let's also note one more Swedish manufacturer - the firm JONSERED, which produces high-quality gasoline powered tools for more than half a century.

The products of the Japanese company SHINDAIWA are little known to our customers, because it does not have such a long history as STIHL and HUSQVARNA.However, professionals respect this brand for the high quality, reliability, practicality and durability of the tool it produces.

Faced with such a variety of firms and having ample opportunities for choice, often a potential buyer is lost. And even if, before making a purchase, he received information from books, magazines, the Internet or just after listening to the advice of friends, then hitting a modern supermarket, he usually hears only laudatory reviews. How to choose the instrument in such conditions is correct?

Choosing a gasoline chain saw

Choosing the instrument of the upper price segment of the market, we can quite afford to slightly abandon the names of brands, focusing on the functions and benefits of specific models.

First you need to decide for what purpose you need a saw. The amount of work that is to be done is very important. If you need a saw for use in the household and you will not use it more than once a week( for example, for the preparation of firewood for a bath or for cutting branches in a garden), then it is worth choosing among small saws. If such a saw you will operate often and intensively, the result may be a spoiled impression of the manufacturer, although, in fact, the wrong choice was made for the saw model. The resource of such saws is limited and they are not designed to perform large amounts of work.

When choosing a saw, hold it in your hand. Do not make a purchase based only on the advertisement of the manufacturer and the standard characteristics of the product. Perhaps you are familiar with the expression "lay down in your hand".When choosing a saw it is very useful. With the same power characteristics, the ergonomic parameters for each saw model can be different. And people differ in their anatomical structure. Therefore, it is necessary to choose the saw correctly which you will be comfortable to use, paying attention to the arrangement and shape of the control levers.

A very important detail of the chain saw is the handle of the inertia brake of the chain. With an inertial brake, even a high-speed chainsaw can be stopped almost instantaneously, which helps to prevent injury to the operator in the event of an emergency. In all chainsaws, regardless of the model and manufacturer, the inertia brake lever is located in one place - in front of the front handle, but the shape and size of the lever, the force at which the brake operates - are different. Therefore, it is necessary to choose a saw that will fit your anatomical features. After all, not only the quality and speed of work depends on how well the tool is selected and adjusted, but also your safety.

Let's say that we have chosen several models of saws that not only meet all of our technical requirements but are also convenient for work and have high manufacturing quality - STIHL MS180C, ZENOAH GZ400 and JONSERED CS 2137.

All of them are approximately the sameweight and size, with the exception of the ZENOAH GZ400, whose bus length is slightly larger. Leaving aside the technical characteristics of these models, we will try to find the most convenient one. And who knows better than yourself what is convenient for you? Therefore, this stage of choice you have to go through without our help.

All listed saws have such an undeniable advantage, as a light weight .Take any one of them in hand and lift it by the front handle. You will feel how well the saw is balanced. When working with such chainsaw you will be less tired, due to the correct distribution of its weight. The exhaust gases generated during operation are removed from all the above models in such a way as to protect the operator from getting into the exhaust stream. Of course, in order to completely protect yourself from the unpleasant effects of combustion products, when working with a saw, you need to take into account the direction of the wind. An additional advantage of the ZENOAH GZ400 is the fact that the exhaust port is equipped with a protective grid. This not only prevents sparks from forming during combustion, but also protects the muffler from foreign objects entering it.

STIHL and JONSERED chainsaws also have spark protection , despite the fact that their models of saws are equipped with silencers without a mesh. But from the accidental ingress of foreign objects into the muffler, they are not insured, and this threatens to fail during work. And although such cases are quite rare, these saws should be treated with particular care, to protect them from breakages, and themselves - from trauma.

At all saws from the side of the hand starter are located refueling points fuels and lubricants. For convenience of the consumer, they are marked with a special marking. An image of a gas station with a droplet marks the fuel cap, and the oil tank is marked with a chain image with a droplet.

The entanglement of refueling points with gasoline and oil is unacceptable, as the consequence may be a serious breakdown. At the chainsaws STIHL and JONSERED the filling points are arranged as follows: the fuel tank is located near the rear handle, and the oil tank is next to the front handle. An additional convenience of the saw STIHL MS180C is the presence of windows that allow visual control of the level of oil and gasoline during operation. At the ZENOAH chainsaw, both filling points are located next to the rear handle. For the convenience of the consumer, they not only have the standard marking, but also differ in color and size. However, if you choose this particular chainsaw, at work you will have to be very careful not to confuse the refueling points.

In addition, it must be remembered that a properly prepared fuel mixture is needed to operate the chainsaw, since the design of its two-stroke engine does not provide for self-mixing of oil and fuel.

Chainsaw service is an important selection criterion.

The most important factor in choosing a chainsaw - serviceability .There are saws with a dense arrangement of machine parts in a tight casing. Agree that in this case the daily maintenance of the saw, including the removal of chips and cleaning from the residues of fuels and lubricants, can become quite a labor-consuming and time-consuming process. Therefore, when choosing a chainsaw, it is worth looking inside the case.

To remove the cover from the STIHL MS180C chainsaw, first depress the throttle key and lower the throttle control lever to the lower position, otherwise the chainsaw mechanism may be damaged.

Further, by turning the special retainer, the cover is easily removed. At the same time you get free access to the chainsaw mechanism and room for maintenance.

The convenience of this model is the possibility of to dismantle the carburetor without having to disassemble the saw body completely, which allows to carry out maintenance as quickly as possible and does not require any specialized tools.

The ZENOAH GZ400 chain saw cover is also easily removable. To do this, just unscrew the screw installed in the cover.

Before the starts servicing the chainsaw, remove the air filter as carefully as possible. If the dismantling is carried out carelessly, the consequence of this may be clogging the carburetor. The front part of the housing slightly overlaps free access to the spark plug, but does not prevent the possibility of quick replacement of the spark plug, if necessary. A significant disadvantage of this model is the fact that quick dismantling of the carburettor is possible only with the use of the tool supplied with the saw.

Remove the top cover of the JONSERED CS 2137 chainsaw only with a special key. The explanation is simple: American standards require restrictions on access to the mechanisms of such tools. And accidentally unscrew three screws, and even those to which the standard keys do not fit, is completely impossible. But do not worry, the process of removing the cover is very simple, and getting free access to the saw mechanism will not take more time than we spent on its description.

A distinctive feature of this particular model of the saw is the ability to perform cleaning of the cooling fins of the cylinder. Such work should be carried out regularly, as this ensures sufficient cooling of the engine during operation.
