How To Choose A Cordless Chain Saw

Cordless chain saws

The cordless saw is a versatile portable tool equipped with an electric motor, which runs on rechargeable batteries. Chainsaws with a battery are akin to a saw in terms of environmental friendliness and the noise produced, but their power is small. Electric and cordless chain saws are very effective in small summer cottages.

Household saw

A household saw will perfectly cope with occasional work at a summer cottage. Its very simple design, low weight and inexpensive materials from which such tools are made allow you to set a low price.

Makita chain saws are considered a universal option. In terms of cutting speed, these tools are slightly inferior to the average, but, for example, the Stihl, with even less power, is more expensive and at the same time less practical. If there is a lot of dust ahead, it is better to purchase a chain saw with a high cutting ability. Quite high cutting speed, admittedly in a bosch chain saw.

If you remember the unenviable fate of domestic chain saws. Almost all of them were oriented towards professional use. But the enterprises of woodworking of steel are massively switching to other equipment, more high-tech, to which, however, Russian saws were inferior very little. But the plight of the domestic chain saw manufacturer was aggravated by this.

Hand saws

A hand or chain saw are power saws for sawing by hand. This saw can be used both alone and together. It is not difficult to use: the object intended for cutting is clasped by a chain on both sides, the tool moves and makes sawing.

The electric chain saw is equipped with an electric motor, which is connected to the saw unit through a transmission system. The engine is operated from the mains, to which it is connected for power supply using an electric cable.

Chain saw applications

Chain saws are professional, semi-professional and household.

Tools

An electric chain saw is an excellent tool, indispensable when cutting building material, any work in the garden, at the dacha, harvesting firewood. In addition, with a certain skill, you can use it to cut materials such as foam blocks, plastic, etc. How to choose a really good tool so that He not only lasts a long time, but also becomes a reliable assistant in the household?

With the current wide range of models with varied functions, it is not so easy to make a choice. Each buyer, of course, would like to get for his money exactly the model that most fully meets his requirements.

Electric chain saws

The electric saw is economical to use, since it does NOT need refueling, the noise during operation is low, and due to the absence of exhaust gases, it can be used when working in closed rooms. An important advantage of modern electric and chainsaws is the presence of a chain brake in the tool. in the event of a dangerous situation, the brake instantly stops the chain. The saw is very convenient during operation, but in comparison with chainsaws, its power is low. The lack of mobility allows the use of such dust mainly in small areas.

The performance of a chain saw depends on the condition of the chain. With a blunt chain, the engine will work with increased load and will lose power, therefore it is necessary to make sure that the chain is in good condition. Any owner of a summer cottage who often has to use a saw to remove excess branches from trees, sawing firewood, knows about the need for frequent sharpening of the chain, but basically it only slightly polishes it to return their sharpness to the teeth. In some cases, it can be quite cost-effective to purchase a sharpener for chain saws.

Types of chain saws. Chainsaw working principle

The two main components of a chain saw are the engine and the so-called saw part, which consists of a base, a bar, and a chain pulled over it. The chain and bar of a chain saw is also sometimes called a headset, since these are removable elements. The chain saw is operated as follows: the engine torque is applied to a chain closed in a ring, which has cutting edges. Moving along the guide bar, the chain sprays using the cutting edges.

Location of the electric motor

Actually, in modern saws there are two location options, longitudinal and transverse. Saws with a side-to-side motor arrangement are great for vertical cuts.

Such a saw is convenient for sawing fallen trees or for harvesting firewood. The disadvantage of this arrangement is the imbalance of the instrument, which causes significant discomfort when holding it in the hands for a long time.

The transverse position of the motor in the chain saw also makes it difficult to cut trees horizontally. Cuts with such a saw are not quite even. But it is worth noting that the price of saws with this motor arrangement is cheaper than models with a longitudinal electric motor.

A chain saw with a motor, which is placed along the body of the device, will help to cut the tree more comfortably. The cost of units with a longitudinal arrangement of the electric motor is higher, but if you overpay, you can become the owner of a universal tool.

Due to the longitudinal positioning, the chain saw is perfectly balanced and comfortable to hold. Such a saw can effectively spray at any angle and the process itself will be more comfortable.

Blade length. Depending on the purpose for which you use the tool, the length of the cutting part (tire) also varies.

Small tires with a length of 30 to 40 centimeters are quite suitable for working in personal plots, cutting branches and preparing firewood. If you need to cut on an industrial scale, a longer bar will be required.

How to choose a good chain saw: the nuances of choosing

Saw Indispensable in a country house. Since the manual version of this tool requires considerable effort from its owner, the advent of automatic chain saws was received with enthusiasm.

The energy source for work can be gasoline or electricity, with the latter option being more popular among non-professionals. Therefore, the question of how to choose the right chain saw is of great importance. But first, you need to figure out what technical elements the saw consists of and what the principle of its operation is based on.

Engine power indicators

The choice of a chain saw for this indicator should be carried out Based on the conditions of use of the device. To cut old branches in the garden, it will be enough to choose saws with minimum power indicators.

In the case of regular and long-term use of the tool, say, for sawing thick trees, it is worth focusing on more powerful units. In the first case, it will be quite enough to choose a saw with an operating power in the range of 1.5-2 kW.

The power of the tool, which will be used often and will perform a large amount of work, should be in the range from 2.5 to 4 kW. In the case of using the device in country houses or in summer cottages, experts advise buying a lower power tool or additionally purchasing a voltage stabilizer in the power grid.

The fact is that the voltage in the electrical network in suburban settlements is extremely unstable and the tool often simply does not have enough incoming voltage for normal operation.

In order to minimize the shortage of voltage, the current increase function is activated in the electric motor. This puts additional stress on the engine, which reduces its overall running time.

Electric Saw Chain Brake

A very essential function capable of protecting the worker. The thing is that when cutting hard trees or other materials, during the contact of the rotating chain with the material, the tool is often sharply thrown up, towards the person, as it sprays.

The presence of the function of stopping the chain, which is made in the form of a plastic shield and located near the tool handle, allows an involuntary hand movement at the time of the saw rebound.

This movement will move the guard forward and stop the chain momentarily. The chain stops instantly, so the possibility of injury to a person is completely excluded.

Overheat protection. This function is a relay that regulates the temperature of the device. When the maximum load is reached, the relay automatically switches off the engine, thereby preventing it from overheating or igniting.

Engine heating can occur for various reasons, but the most common situations are chain seizure during operation or when the oil level in the tool reaches a critical level.

How to choose a chain saw

When choosing a saw, it is necessary to build on the technical characteristics. There are a large number of models of the presented power tool, but each of them is designed for different purposes and different amounts of work.

In addition to individual characteristics, a manufacturer of high-quality electric chain saws is of great importance in choosing a saw.

The choice in favor of a well-known and time-tested manufacturer, despite the often higher price, guarantees high quality and reliability of the tool.

The most famous foreign firms producing high quality electric tools are:

  • Bosch.
  • Stihl.
  • Foresta.
  • Partner.
  • Sparky.

Cheaper, but no less reliable analogues of foreign chain saws are domestic models from manufacturers such as Zenit, Interskol and others. The saw is not the tool to save on.

By purchasing cheap counterparts from dubious manufacturers, you can get a low-quality, heavy, noisy or power tool that does not have proper protective devices.

Electric dust chain design

The tool discussed in this article consists of the following elements:

  • Electrical engine.
  • Metal chain.
  • Guide rail.
  • Oil reservoir.
  • Oil pump.
  • Power cable from the 220 V network.
  • Ergonomic plastic housing.
  • Power and lock buttons.
  • Tire retainer.
  • Chain tension adjuster.
  • Overheating fuse.
  • Safety shield.
  • Lever.

How the saw works

The saw works as follows. After connecting the tool to the 220 V electrical network and pressing the power button, the electric motor starts.

The started motor drives the gearbox, which makes the tire rotate on which the metal chain is fixed.

Actually, with the help of a rapidly rotating chain, the spray is carried out. The oil pump installed in the saw ensures that oil gets into the chain cutting elements.

Through this process, the chain is lubricated. This improves the efficiency of the saw and increases its service life.

Presence of blocking function

This locking device is found in all modern chain saws. If this button is NOT present in some electrical tool, then such a unit is a low-quality fake.

The ability to block dust is an extremely useful function that guarantees safety, eliminates the possibility of accidental and untimely switching on of the tool and the occurrence of accidents.

In order to quickly and efficiently cut wood, you must use a chain saw. This tool is indispensable when it comes to working with wood.

There are many models of domestic and foreign manufacturers on the market. Unlike gasoline counterparts, electric models are more unpretentious in operation, but they are also less mobile and dependent on the presence of a stable voltage.

Choosing a suitable saw model is quite difficult, but following the points described above and Taking into account the advice of professionals, it will be much easier to make the right choice.

Parameter # 5. security

Any saw for woodworking is a potentially dangerous tool. Therefore, when choosing a machine, it is so important to protect yourself from possible injuries while using the tool.

When choosing a power tool, pay attention to the presence of an accidental start lock. It will protect you from danger if you DO NOT comfortably grip the tool with one hand or, after switching on, find that you are not yet ready to work with it.

When working with a chain saw, “kickback” is especially dangerous. It occurs when the end of the bar touches the hard surface of the lumber, as a result of which the tool is sharply thrown back, and its moving chain can injure the operator.

To prevent “kickback”, modern models are equipped with an automatic brake system, which is a flap-shaped lever located under the handle

The automatic brake is activated when the hand slips, when a “kickback” occurs: when pressure is applied to the guard, a spring is activated, which activates the brake and stops the chain.

Chainsaw working principle

Saw. a tool necessary in the household, which is often used when cutting branches in the garden, sawing wood and carpentry.

Compact and easy-to-use tool does not require knowledge and skills in handling a gasoline engine

Initially, hand-held chainsaw models were rather bulky and heavy. Unsurprisingly, the introduction of electric chain saws to the market has been enthusiastically received by most consumers. In addition to ease of use, a significant advantage of the power tool is that it is environmentally friendly, since it does NOT emit exhaust gases during operation. This is especially true when cutting materials in confined spaces.

The main structural elements of the chain saw are:

  • Electric motor in the housing;
  • Guide rails;
  • Chain;
  • Oil pump with oil reservoir.

When the unit is turned on, the motor generates a rotational movement, which is transmitted to the sprocket by means of a bevel gear or direct drive. The sprocket placed in the common plane with the chain begins to rotate it, thanks to which the cutting blade easily cuts wood.

Recently, many manufacturers are equipping models with a centrifugal clutch, warning that during a loop, the breakdown of the electric motor and the saw gearbox.

Electric models of chain saws are famous for their long service life, which is achieved by constant lubrication of moving parts during operation

The chain oil in a special container is pumped by a pump onto the tire, from which it spreads through the chain along the sprockets and the cutting blade. Many models have a lubrication intensity adjustment function that allows you to work with materials of different hardness.

The volume of the container is on average 120-200 ml. This volume is enough for 2 hours of continuous work. The operator’s task is to control the oil level in the tank, otherwise, working “dry”, the motor will quickly overheat and the tool will fail.

To facilitate the task of controlling the volume of liquid, manufacturers make transparent inserts in the case or predict the presence of a special probe.

Parameter # 1. engine location and power

The first thing to look for when choosing a tool is engine power. Not only performance depends on this parameter, but also its durability.

If power surges are common in your power grid, choose a tool with sufficient power reserve. The motor of such a chain saw will not overheat when the voltage is lowered, giving the rated power.

The power of the chain saw motor for the domestic version can vary within 1.5-2 kW, and for the professional one can reach 3.5 kW

If the voltage is unstable, experts recommend choosing models equipped with a thermal control system, which automatically turn off the tool. The thermal relay is activated when the temperature of the motor winding reaches the set threshold. But it should be borne in mind that with too frequent shutdown in conditions of unstable voltage, the performance of the unit also decreases.

If we focus on the location of the engine in the structure, then it can be:

  • Transverse. here the engine is perpendicular to the width of the unit, and its center of gravity is slightly shifted. When working with such a tool, you will have to constantly maintain balance. It is most comfortable to work with it in a vertical plane when cutting from top to bottom.
  • Longitudinal. the construction is a straight line, in which all components are well balanced. This design provides excellent balance of the blade when cornering, giving the tool more maneuverability.

Cross-cut saws are intended for general use. The power of such tools fluctuates around 2 kW, and the mass does NOT exceed 4 kg.

Saws with a longitudinal motor arrangement are indispensable for carpentry work.

The absence of a protruding motor from the side simplifies the work with the tool, but increases the weight of the unit, the value of which can reach 6 kg

Here, a considerable weight of the hands will quickly get tired, and then with such a tool it will not be very convenient to operate for several hours of continuous work. this should be taken into account.

Saw KRÜGER ECSK 25-40

A very good, increased power tool is offered by the German brand KRÜGER, which has long won popularity and consumer confidence. Saw KRÜGER (Germany) has a compact size and is used for harvesting firewood, sawing a bar, sawing off branches and branches. The power of the KRUGER electric saw is 2500 W. Impact resistant plastic protects the device from damage. Functions include automatic chain lubrication, start lock. It is convenient to work: the Kruger electric chain saw weighs only 5 kg.

, which is more than acceptable for a German manufacturer. Without a doubt, this device is the best demonstration of the ideal value for money.

Parameter # 2. chain tension control

Low-profile chains are used in the manufacture of the saw. Although they have lower performance, they are good in that they subject the tool to less vibration, making it safer to use.

The correct tension affects performance and safety of work, therefore, during operation, the saw chain must be re-tightened quite often.

On sale there are models in two versions of chain tension:

  • Classic. to tighten the chain, the fastening bars are loosened and gently moved with a flat screwdriver. This is a rather painstaking method, time-consuming and requires the availability of the necessary tools at hand.
  • Simplified. chain tension is achieved by loosening the nut and shifting the bar with a slider.

The lubrication of the close unit in modern models is carried out using an oil pump automatically. The pump is activated simultaneously with the start of the saw. This greatly simplifies the maintenance of the unit. The saw owner’s job is to control the oil level and add it as needed.

The presence of a lever on the side panel allows you to easily adjust the tension, the system is convenient in that it does not require the use of special tools

Parameter # 3. bus length

The working bus, on which the chain is fixed, can have various modifications. The length of the bar is directly related to the power of the tool. It can reach 30-45 cm.Taking into account that it is unlikely that you will have to cut thick logs in a suburban area, a 40 cm long tire is considered the best option for household work. Tools with a longer tire will be much heavier, more powerful and, therefore, more expensive.

Cut quality depends on the thickness of the cutting blade.

For household tools, the standard tooth pitch is 3/8 ”: the thicker the chain, the more powerful the motor needs to be

Saws from different manufacturers can be fitted with different types of chains and bars depending on the performance of the tool. Over time, movable items will wear out and require replacement. Therefore, in order to prevent problems with finding parts in the future, choose power tools with the most common type of chains.

Household or professional tool?

Like any power tool, the chain saw is presented on the market with household and professional models. Professional tools are more powerful, which allows them to operate without stopping for a longer time. It is better to choose them when you need frequent use.

Most professional models Equipped with the function of maintaining a constant engine speed, as well as vibration protection and comfortable handles

The only drawback of professional chain saws is their high price, which is often several times higher in comparison with household counterparts.

Household chain saws are more designed for short-term work. The time of continuous operation of the tool is limited to 10-15 minutes, after which it is necessary to pause, giving the engine “rest”.

The simple design of THESE models and the use in the production of inexpensive materials can significantly reduce the cost of household chainsaws

In order not to prog, before choosing a chain saw, determine for yourself the scope of the proposed work and the frequency of use of the unit. If you need a tool for seasonal work in the country, it is quite possible to limit yourself to the household option.

How to choose a chain saw: tips and advice from professionals

The chain saw is widely popular among country farm owners. Although it is NOT capable of fully replacing its “sister” with an internal combustion engine, there is no better option for small sawmills. The tool is easy to use: you just need to plug it in to get started. How to choose a chain saw that has a sufficient set of functions, but at the same time will NOT overpay too much? To make a competent choice, you must take into account a number of factors, the main of which we will consider in the article.

Parameters for choosing a quality saw

The modern market offers a wide range of models. Among the well-known brands of well-established manufacturers, the most popular are: Bosch, Sparky, Patriot. There are also less promoted brands, which are often not inferior in the presented functions. Therefore, when choosing a chain saw, you should be guided not only by the advertising of the brand, but also by the performance characteristics of a particular model.

Parameter # 4. soft start

The systems for starting and braking the engine are perhaps the most extreme operating modes of the unit. The reason for this is that at these moments shock doses of current pass through the motor winding, which significantly reduces its resources.

Significantly facilitates operation and protects the motor from extreme loads a soft start system that limits the starting current, allowing the motor to gain speed gradually

The soft start system extends the life of the unit.

The inertial brake allows the motor to stop in a fraction of a second when the tool is turned off, thereby reducing energy consumption.

Types of chain saws

Chain saws are:

Chain saw applications

At home, where great power and long-term work are not required, it is appropriate to use chain saws for a household. The tool has a small engine volume (up to 55 cm3), and the power is about 2.5 kW. Mostly saws are equipped with low profile chains, which determines a smooth ride.

Semi-professional saws will be more powerful (from 2.5 to 4 kW), have a large engine displacement (from 55 to 70 cm3) and are designed for heavier tasks. Semi-professional saws are more versatile, but counting on long, uninterrupted daily cutting of wood is not worth it.

Professional chain saws have an engine capacity of over 70 cm3 and a power of over 4 kW. Equipped with full profile chains for maximum performance. Only such a tool is able to cut from time to time throughout the day and without interruption. Dust materials are the most durable and reliable, and the resource reaches 2500 hours. Professional dust can be applied anywhere but the main area. Forestry and industrial timber harvesting.

Saws

Saws operate on the basis of an electric motor that drives the saw element. The electric saw operates from the mains, for connection to which a cable is provided. The saw is also environmentally friendly, as it does NOT emit combustion products into the atmosphere. After that, you can easily work with it indoors, for example, in a shop, inside facilities under construction, in a garage. Also, the saws are NOT noisy.

Among the disadvantages: the vast majority of models are low-power (not for an industrial saw for wood), and work can also be carried out in a limited area, as far as the network cable and carrying allow.

Chainsaw

The most powerful saw power tool available. Basically, all chainsaws run on a two-stroke internal combustion engine and drive the watch part through the gear system. The clutch of the device is centrifugal, thus, the web at idle speed remains stationary, and therefore safe. In case of force majeure, an instant stop of the chain is provided.

Of the minuses of the chainsaw, you can single out High noise. But in terms of performance and versatility, the chainsaw is unmatched, both at the construction site and in the forest, and at home.

When choosing which type of saw is best, the key is how you plan to use your chain saw. Since it is one thing to dust small branches on the kindling of the stove, and quite another. Felling perennial trees with solid wood somewhere in the forest all day.

Cordless chain saws

Cordless saws operate on a battery, which significantly expands the range of applications, in contrast to electric counterparts. This is the best option when work is coming up on a small summer cottage and garden.

How to choose the right chain saw?

There is a convenient tool for each type of activity. And if we talk about manipulating wood, then among the leading devices is, of course, a chain saw. Its area of ​​application is very diverse: from sawing to overthrowing trees into separate stumps to figured cutting of bowls and holes. With the help of a chain saw, firewood is harvested for the winter, in the stove and fireplace, construction work is carried out.

Currently, there is a huge mass of such instruments on the Ukrainian market. “What to choose for your specific goals?” not an easy question, but you can figure it out. What we propose to do.

How a chain saw works and how is it built

Chain Saw. A power tool, the defining component of which is a circuit, closed in a ring. When the motor is started, it moves along the guide rail and thus cuts off the wood layer.

Currently, there are several types of tools among chain saws: hand saws, electric (network), gasoline, cordless. Depending on the type of power supply, the saws differ in design. So, gasoline saws have a tank for the fuel mixture, when there is such a component in electric saws. But they provide a cable for connecting to the network and a rechargeable battery.

Based on how the engine is located in the device, there are transverse and longitudinal chain saws:

Saws with the motor along the body are more convenient if you plan to dust the branches on a tree, in places with difficult access. Such a saw is maneuverable, it easily and safely dust wood from any angle.

Transverse chain saws. Ideal for cutting logs. They are not heavy, because the load on the back is small, and such a unit is also more powerful, which makes it possible to cope with tasks faster.

It should be added that modern chain saws have a protective shield in front of the handle. And the handle itself is covered with non-slip material, which provides a secure grip of the tool.

Mechanical saws

Everyone knows the simplest method of sawing wood with a hand saw (hacksaw, Druzhba saw), when a lot of effort is needed. An option that works, but does not give the opportunity to do work quickly and efficiently.

Features of the choice of a chain saw

When choosing dust for home or work, the following criteria must be considered:

Engine power. Above we have already talked about what capacity and for what work is suitable. One has only to add that it is better to buy a chain saw with potential for future use. After all, it so happens that I bought one tool, and very soon a resource is required, which the current saw cannot be given. After that, it is better to spend money once and stock up on good equipment for all occasions. As a rule, the best option for home. Saw 2 kW (Interskol PC-16 / 2000T, Intertool DT-2201, Black Decker CS1835).

Engine orientation. Transverse. For cutting logs, where the operator is in a constant tilted position. Dust rips will be appreciated by those who work with a saw in places with difficult accessibility, for example, between branches on a tree.

Bus length. A longer bar can cut a larger diameter log. For most household sawing tasks, a 30-40 centimeter tire will be sufficient (Partner P340S, Rebir KZ1-400, Husqvarna 550XP, Stiga SP426-40, Vitals Master BKZ 3717o).

The presence of a chain brake. Protects against kickback. Saw. The instrument is dangerous, and if you fix it in your hands incorrectly, you can easily leave your fingers. And when working with hard wood, dust can be thrown towards the operator’s head, hence injuring him. It is the chain brake that prevents such troubles.

Overheat protection. By means of a special thermal relay, if the temperature indicator of the system is exceeded, the power supply to the saw is turned off. In this way, premature tool failure can be prevented.

Blocking of inclusion. Another element of human safety, does not allow you to press the start of the saw accidentally. As a rule, all famous brands of saws have a lock: Einhell, Husqvarna, Bosch, etc.

Fuel and oil tank capacity. The larger it is, the less often you will have to stop to refuel the tool with consumables.

It is worth noting that cross-cut saws are considered more durable and reliable, since their design is simple, and saws with a longitudinal motor arrangement are more durable. We also recommend buying dust with the “soft start” function, so that during the start the saw does NOT make a sharp jerk to the side, which is quite dangerous.

The chain saw consists of the following elements:

  • Engine. In gasoline saws it is a 2-stroke internal combustion engine, in electric saws it is an electric motor. The motor generates rotational movements and transfers them to the chain.
  • Reducer. This element is required to transfer power from the motor to the tracking headset.
  • A saw chain is made up of different types of links that cut, guide and connect each other. Its width is wider than the width of the tire, which prevents jamming.
  • The bus is the element along which the chain is guided. It is constantly exposed to heavy loads, therefore it is made of durable materials. most often it is steel. The chain runs in a groove on the outside of the tire where oil is fed.
  • Chain tensioning mechanism. It can be key and keyless. The advantage of the second is that it is not necessary to carry a key with you: you can tighten the chain with a handle or a nut.
  • Oil tank. Oil is poured there for automatic chain lubrication.
  • Emergency brake. needed to protect against kickback. When throwing the saw, the hand moves forward by inertia, where this brake is installed. A person involuntarily presses on it, the chain stops and excludes the possibility of crippling oneself.

These are the main structural elements of the saw. Gasoline tools still have an ignition system. in most models, this is a contactless electronic ignition, which makes it easier to work with the tool. To ensure normal engine operation, chainsaws have a carburetor that mixes oxygen and fuel. In addition, the design also includes a fuel system consisting of a gas tank, a hose and a fuel filter.

The principle of operation is extremely simple: after pressing the button, the engine starts, which begins to create a rotational impulse and transmits the impulse through the gearbox to the tire, and the chain begins to rotate and cut the material. At this time, oil is automatically supplied to the drive through the oil pump, which is necessary to ensure smooth movement and eliminate overload and breakdown.

The advantages of an electric saw:

  • The absence of waste fuel emissions into the atmosphere allows you to use it even in a closed room, it is not harmful to the person who uses it;
  • Consumes little electricity and does not require refueling, therefore it can be considered economical;
  • Easy to operate and safe;
  • There is a lot of noise during operation.

Unfortunately, it is not very portable, you will always be tied to the power cord. You may need a lot of extension cord. The saw models do NOT differ in high power and are used only for domestic needs. Always check the condition of the chain: when it is dull, the engine is heavily loaded and breaks quickly.

Parameter # 2. chain tension control

Low-profile chains are used in the manufacture of the saw. Although they have lower performance, they are good in that they subject the tool to less vibration, making it safer to use.

The correct tension affects performance and safety of work, therefore, during operation, the saw chain must be re-tightened quite often.

On sale there are models in two versions of chain tension:

How To Choose A Cordless Chain Saw
  • Classic. to tighten the chain, the fastening bars are loosened and gently moved with a flat screwdriver. This is a rather painstaking method, time-consuming and requires the availability of the necessary tools at hand.
  • Simplified. chain tension is achieved by loosening the nut and shifting the bar with a slider.

The lubrication of the close unit in modern models is carried out using an oil pump automatically. The pump is activated simultaneously with the start of the saw. This greatly simplifies the maintenance of the unit. The saw owner’s job is to control the oil level and add it as needed.

The presence of a lever on the side panel allows you to easily adjust the tension, the system is convenient in that it does not require the use of special tools

Dust classes and purposes of their use

All models produced in our time can be divided into three classes depending on production characteristics and place of use. Household saws include small tools with a power of NOT more than 3 kW and an engine capacity of 40-50 cubic meters. See They are specially made for rare use and are NOT intended for cutting heavy and sturdy wood.

For medium-heavy work, a semi-professional saw with a power of 3-4 kW is required. Despite the higher class, they are also NOT intended for daily hours of work.

For industrial purposes, professional chain saws are used, the engine capacity of which exceeds 70 cubic meters. See, and the power is 4 kW and above. All parts are made of the most durable materials to ensure long-term hard work without breakage. Forest workers use only such tools.

How to choose a chain saw for a summer residence: determining the type of saw you need

The first thing to understand before buying is what type of tool you need. There are the following types:

  • Electric, in which the movement of the sawing element is due to the operation of an electric motor. Works only on mains via cable.
  • Rechargeable. can be considered a subtype of electrical, since it is charged from the mains. portable and mobile than electric. Before choosing a cordless chain saw, be sure to determine the exact area of ​​your work, because it is only good for a small area.
  • Gasoline. runs on a gasoline engine and is the most powerful among all the above types.

Sometimes you can find a hand chain saw, which consists of a chain with links and handles on both sides and requires a lot of joint efforts in order to cut the material. Now she has already gone out of use.

Overview and general characteristics of the tool

Before choosing electric chain dust or any other, it is important to study the structure and features of this tool. In any type of chain saw, spraying is achieved by moving a closed chain with gears along a guide. These saws are used not only for household purposes. All loggers and firefighters use improved versions of THESE tools, allowing them to cut even thick trunks of many years. Some artisans use chainsaws to create ice sculptures.

For the first time, a tool resembling a modern analogue was used in medicine for cutting bones. It was invented in 1830. It has little resemblance to a modern saw. Gradually, the device was modernized, new parts were added and from the 20th century, the massive use of chain saws began.

Parameter # 3. bus length

The working bus, on which the chain is fixed, can have various modifications. The length of the bar is directly related to the power of the tool. It can reach 30-45 cm.Taking into account that it is unlikely that you will have to cut thick logs in a suburban area, a 40 cm long tire is considered the best option for household work. Tools with a longer tire will be much heavier, more powerful and, therefore, more expensive.

Cut quality depends on the thickness of the cutting blade.

For household tools, the standard tooth pitch is 3/8 ”: the thicker the chain, the more powerful the motor needs to be

Saws from different manufacturers can be fitted with different types of chains and bars depending on the performance of the tool. Over time, movable items will wear out and require replacement. Therefore, in order to prevent problems with finding parts in the future, choose power tools with the most common type of chains.

Chain saw: design, principle of operation, rating of the best models

A chain saw is a tool that is very necessary in the household, especially when living in a private house. He helps in construction, cleaning the territory, and solves many other problems. Let’s talk in more detail about how to choose a good chain saw that will serve its owner for a long time.

Parameter # 1. engine location and power

The first thing to look for when choosing a tool is engine power. Not only performance depends on this parameter, but also its durability.

If power surges are common in your power grid, choose a tool with sufficient power reserve. The motor of such a chain saw will not overheat when the voltage is lowered, giving the rated power.

The power of the chain saw motor for the domestic version can vary within 1.5-2 kW, and for the professional one can reach 3.5 kW

If the voltage is unstable, experts recommend choosing models equipped with a thermal control system, which automatically turn off the tool. The thermal relay is activated when the temperature of the motor winding reaches the set threshold. But it should be borne in mind that with too frequent shutdown in conditions of unstable voltage, the performance of the unit also decreases.

If we focus on the location of the engine in the structure, then it can be:

  • Transverse. here the engine is perpendicular to the width of the unit, and its center of gravity is slightly shifted. When working with such a tool, you will have to constantly maintain balance. It is most comfortable to work with it in a vertical plane when cutting from top to bottom.
  • Longitudinal. the construction is a straight line, in which all components are well balanced. This design provides excellent balance of the blade when cornering, giving the tool more maneuverability.

Cross-cut saws are intended for general use. The power of such tools fluctuates around 2 kW, and the mass does NOT exceed 4 kg.

Saws with a longitudinal motor arrangement are indispensable for carpentry work.

The absence of a protruding motor from the side simplifies the work with the tool, but increases the weight of the unit, the value of which can reach 6 kg

Here, a considerable weight of the hands will quickly get tired, and then with such a tool it will not be very convenient to operate for several hours of continuous work. this should be taken into account.

Saw KRÜGER ECSK 25-40

A very good, increased power tool is offered by the German brand KRÜGER, which has long won popularity and consumer confidence. Saw KRÜGER (Germany) has a compact size and is used for harvesting firewood, sawing a bar, sawing off branches and branches. The power of the KRUGER electric saw is 2500 W. Impact resistant plastic protects the device from damage. Functions include automatic chain lubrication, start lock. It is convenient to work: the Kruger electric chain saw weighs only 5 kg.

, which is more than acceptable for a German manufacturer. Without a doubt, this device is the best demonstration of the ideal value for money.
