The subtleties of the choice and operation of electric chain saws

An electric saw is a valuable household tool. However, choosing and operating it is not easy. It is required to carefully study all the nuances.

A quality electric chain saw does an excellent job of tackling small jobs. It is impossible to use such a device in the field or simply for large trees. However, if you have to work in confined spaces or in hard-to-reach areas, the situation changes.

The inherent advantages of the electric saw are as follows:

• efficiency in work;
• the lightness of the instrument itself;
• no environmental damage.

Since a saw with an electric motor weighs an average of 3 to 5 kg, even women and teenagers can use it. There are many models of sawing devices on the Russian market. To deal with them correctly, you need to take into account what value each parameter has.

The structure of an electric chain saw differs only in the type of power plant.

The main components are as follows:

• electric motor;
• reservoir for lubricant;
• oil pump;
• tire;
• chain element with cutting parts.

The electric motor can be installed transversely or longitudinally. In the first case, the rotation from the motor shaft is broadcast directly, and in the second, a gearbox is used. Thanks to the sprocket located in the same plane with the aggregate tire, the chain can be easily tensioned.

Since the saw blades are wider than the main busbars, jamming in the material is excluded. An additional benefit of such a solution is the increase in the speed of work.

Since the saw chain and bar can easily wear out, a lubrication system must be used.

The chain spreads the grease collected from the bar, and as a result, both the drive and guide sprockets are processed. Of course, all these components must be carefully coordinated with each other.

The electric saw can be used for both small and large jobs. The chain tool is deservedly considered a compromise between gardening and construction tools.

It can be used for the following purposes:

• sanitary pruning;
• forming scraps;
• preparation of furniture;
• preparation of firewood for the winter.

The electric saw is more durable than the gasoline counterpart. But only with strict observance of the basic rules of operation. Since the coupling of the armature with the gearbox is carried out according to a rigid scheme, the slightest overload can lead to damage to the motor.

A dedicated tool lasts much longer despite increased uptime. When you have to work 3 or 4 hours a day, you can safely give preference to a home device, because in this case, special wear resistance is not required from structural materials.

The main purposes of using such a tool are as follows:

• cutting down trees;
• sawing firewood;
• trimming boards during the construction of a fence and other work;
• cutting chipboard, laminate and similar tasks.

At home, electric mini-saws are often used, which help save space. This is the ideal solution if the stationary circular saw is redundant.

Such a device will be able to perform the following actions:

• cut the tree along and across the fibers;
• cut plywood, chipboard and so on;
• to process soft grades of metal.

The mini-saw, along with its compact dimensions, stands out for its low weight - it does not exceed 2 kg. Low power and small blade size result in limited cutting depths. Most often, the saw blade is placed in the front. The steel grade and the geometry of the disc teeth are selected according to the material to be processed.

If it is very hard, hard metal solders are needed, but the acceleration of work turns into a deterioration in the cutting geometry.

It should be borne in mind that a high-quality mini-saw is a rarity. Almost the entire assortment of retail and chain stores is made up of heavy universal devices.

If the power is 400 W, it will only be possible to cut plywood and thin strips. The fast-spinning disc diminishes the hopes of sawing plastic.

The most complex work is performed by professional-grade equipment. For foam blocks and when cutting on aerated concrete, you can use saber saws and structures of the "alligator" type. A special saw designed to process aerated concrete must always be powerful and high-performance, otherwise it will not cope.

The best reciprocating saws for processing stone materials of natural and artificial origin are equipped with victorious solders and specially hardened cutters.

This cermet formulation includes hard metals such as cobalt and tungsten. The total power of the reciprocating saw ranges from 400 to 1600 W, in its design it resembles an improved hand hacksaw. The undisputed market leader is the Bosch reciprocating saws, which are distinguished by their impeccable workmanship.

But the saber tool can be improved even more. We are talking about "alligators". The grooves made in the bar are fitted with a pair of parallel blades. The cut occurs simultaneously in two opposite directions at the highest possible speed.

The alligator scheme has the following advantages:

• maintaining a straight line even with excessive heating of the working part;
• elimination of the reactive effect;
• ability to work in confined spaces;
• balancing a pair of canvases (they mutually damp vibration).

Small reciprocating saws can also be used for metal work. This is most likely a hybrid of a chain machine and a jigsaw.

It's better to start the review with cheap modifications. All the same, for household purposes, there is no particular need to purchase expensive professional devices.

• Greenworks version G40CS30 deservedly leads in relation to other battery versions.Yes, cutting down timber on a large scale will not work. However, the device is quite suitable for use at home or in the country. Some inconvenience can be caused by the generated noise - it reaches 94.7 dB. Average working session time is 1 hour. The manufacturer has managed to provide a decent level of build quality. The powerful and inexpensive saw already has many fans.

• For indoor use among budget class products the best fits Champion CSB60... The engineers were able to think over the design properly, as a result, it helps to remove unnecessary thickets in the garden, and prepare for a small-scale construction.

• If you need the most reliable devices, you need to pay attention to the products of a Japanese manufacturer - for example, Makita BUC122Z... The advantages of this model are relative lightness, flawless installation, small dimensions, ease of use and the ability to quickly tension the chain.

But still, reviews show that budget electric saws do not work stably enough.

• A chain saw is an example of a truly reliable machine. Husqvarna 436 Li... It operates at a constant speed with a tire length of 35 cm. The noise level reaches 100 dB. A chain braking device is provided to protect users.

• Similar devices include Karcher CS 330 BP... The sound volume of such a device is 99 dB. 1 charge is enough for 108-405 minutes depending on the specific conditions. The dry weight is 3.76 kg. A 50 V battery is optional. As in the previous case, the chain brake is installed.

Among the products of Russian production, attention is drawn to itself Parma brand... Despite all the perturbations in the country, it has been produced since the 1970s. The M6 ​​model is considered the smallest and has limited power, which in some cases is just justified, because not everyone needs to cut large logs in huge quantities. But the almost zero risk of overloading a home or apartment power grid is very important.

Therefore, the resource has slightly decreased in comparison with the samples produced in the 1980s. However, it will still be difficult to find analogs that are similar in terms of price and quality. A decent fit of parts allows you to work efficiently. The design is made as ergonomic as possible, minimally fatiguing of the hand.

Of foreign high-quality saws, it is worth mentioning Husqvarna 420EL... The power of the device is 1800 W. Thanks to the 35 cm busbar, you can do almost all everyday work. As the chain travel is carefully selected, maintenance is not a problem. The only noticeable weakness is the 5 kg weight. Because of her, very long work provokes fatigue.

Even a cursory acquaintance with the electric chain saw market shows that it is difficult to choose the right model according to the manufacturers' descriptions. Each firm strives to show that all of its models are almost universal. But there are universal principles that allow you to choose the device that is optimal for a particular case. So, the power of 2000 W and more is really needed only by those who are going to saw thick trunks.

An important role is played by how the motor is delivered - longitudinally or transversely. There is a choice between reliability, price and the ability to work in a small space. The length of the bar determines how deep the cut will be made. But this parameter is also influenced by the power of the bus itself.The products of well-known manufacturers who value their names are all right here: the power grows proportionally with the addition of length.

Given the width of the busbar groove, it is easy to estimate the strength of the chain to be installed and its estimated service life. For domestic use, thin chains are quite justified.

The pitch of the chain element must be proportional to the power of the electric motor. It is important to understand that the increase in performance with increasing step is achieved at the expense of coarser work. In addition, the vibration level rises. Worst of all, the force of the chain against the workpiece increases. This not only complicates the work, but also makes it noticeably more dangerous.

At the same power, they will be heavier than plugged into an outlet. Autonomy is the only advantage of this design. It is necessary to approach the choice of this technique as carefully as possible.

It is imperative to remember every second that a chain saw, even with the most modest power, presents a great potential danger. Therefore, you can work with her only in an impeccably sober state.

Children and pets should not be allowed near the electric saw. But you need to take care of protecting the device itself. It will be preserved only if it is connected to the mains with the standard voltage. When this voltage is 15% below normal, the saw may even run ... but the level of load on the motor increases disproportionately. With a very long and hard work, this turns into a quick loss of resources.

Before starting work, it is imperative to make sure that the oil tank is full and its lid is closed.... It should also be assessed whether the chain brake is working properly, whether the start interlock is activated. When sawing, do not apply excessive pressure on the tool. High-quality fixation of workpieces and supports for them is very important.

Do not cut in poor lighting conditions, in damp places, or on slippery, unstable surfaces.

Installing and tensioning the chain is quite simple. In most models, a special regulator is provided for tightening the working part.

It is recommended to carefully read the instructions when preparing for work for the first time.... The typical sawing cycle is 40 seconds of action and 20 seconds of stopping. It is undesirable to break such a rhythm even in the presence of thermal protection.

Proper preparation for using the electric chain saw requires wearing protective gloves, face shield, goggles, and earplugs.

If you have to work on the street, it is necessary to put the table or the trestle not only stable. It should be dry and clean. It is imperative that there are no objects in the vicinity that easily catch fire when heated.

Sawing through an already started cut should be carried out doubly carefully. Blunt chains are not allowed. Even with an acute shortage of time, the workpieces are processed sequentially.
