Electric saw

A power saw is a portable mechanical tool powered by an electric motor. Most modern electric saws are universal tools that can help in solving various household problems. Let's look at the structure of electric saws, the features of their independent choice and practical use, and also get acquainted with the rating of the highest quality modern models.

Electric saw structure - what does the tool consist of?

Almost all electric chain saws that are currently on sale have an almost identical design. Their device consists of the following main parts and mechanisms:

• electric motor operating from a network with a voltage of 220 Volts;
• removable bar and chain with a sprocket - a saw set responsible for sawing wood;
• chain tensioner and tension level regulator - mechanisms that allow you to adjust the tension of the saw element without using tools;
• lubrication system - a set of parts and mechanisms responsible for distributing lubricant to the bar and chain;
• chain braking system - consists of a safety relay and a protective shield that prevents the operator from injury during a kickback;
• handles for comfortable work with an electric saw;
• power cable;
• direct drive or bevel gear – the first mechanism is provided if the electric saw motor is located in a transverse position. The second mechanism is equipped with saws with a longitudinal motor arrangement.

The conclusions of experts and practical indicators confirm that a more reliable and convenient option for use is a chain saw with a transverse motor. Its design is much better balanced, so working with it does not tire the operator so quickly.

Electronic chain saws. Which ones are better?

In a private home, it’s no different at the dacha without a saw. It is very difficult to cut down an old or unnecessary tree, arrange a site, carry out construction and repairs without this tool. It will also help when sawing various boards and logs. If you are not going to visit the forest to prepare firewood, then an electric chain saw will do. Which model is better? At the moment, meet to figure it out!

Types of electric saws.

• A circular (parquet) saw will help you cut wood, plywood, chipboard, plastic, metal (each of them has its own disc). Parquets can be manual and mounted on a frame.
• Reciprocating saws are used when working with wood in places where other equipment is difficult to reach. The cutting blade has a length of up to 35 cm. It is used for installation and roofing work.
• An electronic jigsaw will help you cut a curved hole of any shape in wood, laminate, ceramics and sometimes metal. However, you cannot cut down a tree with a jigsaw.
• An electric chain saw, a powerful and reliable tool, will help you do this. With its help, tree crowns are trimmed and shaped, and small construction work is carried out.

Which chainsaw is best? Electric or petrol?

Gasoline and electronic saws are similar in design and operating mechanism. Since gasoline is not poured into the electric saw, it does not need a tank. That’s why there is only an oil tank (0.09-0.27 l, depending on the manufacturer).

Most models of electric chain saws, especially older ones, do not have a clutch. This is due to the fact that it is not difficult to manage them anyway. However, modern tools, despite this, are equipped with different clutch variations. This is due to the fact that the heavy rotor of the motor does not stop when it suddenly turns off, the chain continues to spin. When the clutch is present, its rotation quickly stops and the chain stops. This reduces injuries and protects the saw from damage.

Advantages of an electric chainsaw over a gasoline one

• Availability of power supply. There is no need to take and deliver gasoline for it.
• It is much quieter than a chainsaw.
• Lighter in weight.
• Does not create exhaust gases and does not pollute the environment.
• You can work indoors.
• There are no problems with starting in winter.
• Easy to turn on and easy to operate.
• An electric saw is cheaper than a gasoline saw.

Flaws

Electricity is not always available at the place of work. For such cases, you will need a cordless chainsaw. Therefore, when purchasing, inquire about the possibility of autonomous operation. The battery will have to be taken separately. If you often intend to work far from a source of electricity, its purchase will be justified.

You should not buy an electric chain saw to prepare firewood for the winter . Its speed is almost one and a half times lower than that running on gasoline. Therefore, it will take longer to saw with it, and it will also fail faster.

The operation of an electric saw is very dependent on voltage fluctuations. And the network itself in the house cannot always withstand quite a decent load from the saw.

Electric chain saw device

It is approximately the same as that of a chainsaw. The rotating motion from the engine is transmitted to the chain through a sprocket (transverse arrangement) or a bevel gearbox (longitudinal arrangement).

The chain, connected in the form of a ring, moves along the tire during operation. Its rotation speed is approximately 13 m/s. The tire comes in lengths from 30 to 40 cm.

Power

The weight of the instrument (from 4 kg to 6.8 kg) and its price largely depend on the value of this indicator. Electric chain saw power from 1000 W to 2800 W. Therefore, the value cannot be judged on performance . The manufacturer indicates power consumption, not productive power. The efficiency of the model, which depends on the brand, is of great importance here. It is usually higher for expensive models.

When choosing a tool, you need to take into account possible loads and leave a reserve so that it can cope with increased loads. In addition, a saw with high power does not react so strongly to voltage changes.

Ergonomics

The electric chain saw motor can be located along and across the bar . It is more convenient to work with a saw with a longitudinal arrangement. Especially if you have to use it in different planes. In addition, the balancing of such units is better than transverse ones. These models are more expensive, but not significantly.

If you have a choice, get a power saw with a soft start. It is stronger and more durable.

Chain tension and adjustment

With constant use of a power saw, the chain gradually sags. To work further, it needs to be tightened. To do this, the saw is disassembled and adjusted using tools. This is not very convenient and takes a lot of time. Therefore, some manufacturers produce saws with a chain that can be easily adjusted using a quick tension system. There is no need to disassemble the case and look for the necessary tools. By loosening the large nut (“wing”), the tire can be easily moved in the desired direction.

Chain lubrication

If there is insufficient lubrication, the saw motor quickly fails. Therefore, you cannot miss the moment when you need to add oil. As the chain accelerates, small drops of lubricant should appear on the working surface. If they are not there, then you urgently need to replenish the stock. Oil is poured inside through a special hole. It is convenient to control its level by looking through the window.

You need to take special oil designed for chain saws. It is best if it is the same brand as the saw.

In many models, oil application occurs automatically. The auto pump turns on along with the engine and lubricates the cutting surface. It saves oil and does not spray it after switching off or during a short stop.

READ Which Oil Is Best For Lubricating Chainsaw Chains

Chain brake

Modern models instantly stop the saw in the event of a “kickback” when touching the surface being processed. The hand, jerking back from the oncoming blow, hits the shield, which interrupts the movement of the chain. This extends the life of the saw and reduces the risk of injury.

Precautionary measures

When stored in a cold room, condensation forms in the motor windings. This results in a short circuit. In spring, the saw needs to be dried in a warm place for at least a day to remove it.

It is strictly forbidden to work with an electric chain saw in the rain.

Particular attention should be paid to the voltage in the network. If it is very low, then the saw motor (in the absence of protection) overheats greatly. The result could be melted insulation or a shorted armature.

Engine overload occurs when working with a chain with blunt teeth.

The saw needs to be adjusted after every day of work.

Check the oil level regularly. If there is no automatic lubrication system, then the saw bar needs an additional one. To do this, after work it is immersed in a container with oil.

At the end of the working day, check the fastening of parts, which may become loose due to vibration, the serviceability and insulation of the wiring.

If the saw worked easily and did not require excessive effort, then it probably does not require special adjustments. In this case, the chain is removed, cleaned and stored.

Cordless saws are protected from direct sunlight.

Price-quality ratio"

The cheapest electric chain saws can be bought for 4 thousand rubles. Often these are low-quality products that quickly become unusable. But it’s also not worth looking for the most expensive one if you don’t intend to work with it professionally.

When buying a saw, you need to decide what you will be doing. It should be noted that household electric saws are no different:

• durability;
• time of continuous operation.

What types of electric saws are there - types and descriptions

Nowadays, electric saws are used not only for work in the garden, but also as assistants in performing various household, repair and construction tasks. Depending on the area of ​​application and functions, the following types of electric saws are distinguished:

• chain saws - tools of this type are used in the garden to care for trees and prepare the required amount of firewood for heating. The working element of such saws is a saw set, which includes a bar and a chain. The market also offers garden band saws, the working part of which is a steel band instead of a chain. If necessary, to work with chain and band tools, you can use various attachments for electric saws, which will allow you to cut metal or foam concrete;

• Circulating electric saws - among their main advantages is maximum cutting accuracy. Because of this, circular saws are often used around the home to make various wood and metal parts. Tools of this type can be used for cutting wood, metal, polyvinyl chloride and other materials;
• jigsaw electric saws - tools of this type are intended for precise figured sawing of laminate, wood, PVC pipes and metal. Among the features of such electric saws, high vibrations of the cutting part should be highlighted. Thanks to this, when using jigsaws, longitudinal and transverse cutting of materials can be performed;

• reciprocating electric saws - equipment of this kind allows you to perform repairs and cutting in hard-to-reach places. Electric reciprocating saws can cut not only wood, but also metal or foam concrete;

• electric hacksaws - equipment of this kind is very similar in form and function to tools of the previous type. The only difference between them is that hacksaws are more powerful and durable, which allows them to be used for cutting harder materials.

Each of the listed types of equipment is presented on the market in models with different characteristics. Powerful tools are suitable for use in industry and construction, while small models with more modest performance can be successfully used in everyday life.

How to choose the right electric saw - tips for beginners and more

Choosing an electric saw for gardening and other household purposes is a rather difficult task, especially if the buyer does not have the experience and necessary knowledge. To choose the right tool that will meet your specific requirements, you should study a number of basic factors. Their list includes:

• engine power - the higher this parameter, the larger the equipment will be. As a rule, a saw with a power of 2 kW is optimal for household needs, but we must not forget that the tool’s motor must have a certain power reserve. This is required in order to avoid excessive loads on the device motor;
• the presence of a soft start function - at the moment of starting the saw, the maximum current affects it, which leads to increased wear of the engine. The soft start option allows you to avoid this and extend the life of the electric saw;
• chain brake - this mechanism allows you to avoid kickback when the saw set comes into contact with the surface being cut;
• an automatic lubrication system is a set of elements and mechanisms whose main task is to distribute the required amount of oil to the saw bar and chain;
• 12 Volt battery – the presence of this element allows you to temporarily use the tool in places remote from a direct power source.

In addition to all the listed parameters, the availability of spare parts for the selected electric saw is of great importance. In most cases, finding spare parts will not be difficult, since brushes, gears and other consumables are almost universal and are suitable for completely different electric saws. However, there are still tools on sale whose malfunctions can only be repaired using exclusively original spare parts.

Advantages of electric drive

An electric saw is an excellent, relatively inexpensive and quite productive tool that can easily replace the owner with a regular wood hacksaw, bow saw and two-handed saw. Compared to gasoline analogues, the electric drive has a lot of undeniable advantages:

• No exhaust gases, which allows you to use the tool even in enclosed spaces.
• Significantly lower noise levels.
• Lower cost.
• Small weight and size indicators.
• Easy to maintain and manage.
• High maintainability due to the simpler design of the power unit.

In addition, electric saws do not require fuel costs and work well even at sub-zero temperatures.

How to use a power saw - recommendations for beginners

Proper operation and care of the electric saw are the most important factors on which the service life of the tool you choose depends. The instruction manual and a number of factors can help with this; if you adhere to them, you will be able to work with the equipment without worrying about its breakdown. The basic rules for using a saw include:

• Sharpen the saw chain regularly - this will create minimal load on the tool’s motor. Chinese electric saws suffer especially badly from working with a dull chain - because of this, their engines overheat almost instantly;
• store the electric saw correctly - this issue will be especially relevant for batteries, which should be stored only in a warm and dry room;
• Do not use the saw under any circumstances during strong voltage drops in the network - some models of equipment are not equipped with a protective relay, which will lead to instant overheating and failure of the saw motor. The same Chinese saws suffer especially often from voltage surges;
• Operate the saw only in a dry room, away from sources of water and moisture.

Compliance with all of the above recommendations will help you avoid sudden repairs of your equipment and unnecessary financial costs.
