How to choose a chain electric saw
In addition to individual indicators, in the choice of an electric saw, a manufacturer of high-quality electric chain saws is of great importance. 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 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 electric chain saws are domestic models from manufacturers such as Zenit, Interskol and others. The electric saw is not a 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.
Engine 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 an electric 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 do 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.
Criteria for choosing a good electric saw
For each category of user, the criteria for a good saw will be different. For a professional they are one, for a summer resident - others. General recommendations imply the purchase of a quality tool, safe and functional, which can serve for a long time.
A quality saw must meet the following requirements:
- be powerful and productive;
- not cheap, but not too expensive;
- economically use lubricants and fuel;
- be ergonomic (with comfortable handles, balanced center of gravity of the body and blade);
- ideally, give out minimal vibration;
- meet safety requirements;
- contain an easily tensioned and replaceable chain.
User manual
Electric Chainsaw The Gauge is a traumatic tool and, if used incorrectly, can harm the operator's health. Therefore, before starting operation, be sure to read the instructions for use.
Before using the chain saw, be sure to inspect the plug and cable for integrity. They must be sealed and free from any damage.Carrying out work with electric saws Gauge is possible only in dry weather and with dry wood, since moisture can get inside the engine and lead to its failure.
When working with the Power Saw Gauge, the cable should always be behind the operator. It must not come into contact with hot or sharp surfaces.
If you are cutting down branches or a tree as a whole, be sure to think over the place where the wood falls, it should not fall on the cable or the operator.
Criterias of choice
Power. This criterion is considered the most important. It affects the number of revolutions of the blade, as well as the depth of cut. If you plan to do only light household chores with the help of a circular saw, options with a power of up to 1200 W are perfect.
If the work is more complex and voluminous, it is best to consider models with a power of more than 1600 watts.
Experienced craftsmen strongly advise beginners to purchase a power tool with a margin of power characteristics so that in the future there will be no problems with its use.
Disc diameter. An equally important parameter affects the cutting depth. When using a circular saw for domestic purposes, the ideal option is with a diameter of 89-185 mm, capable of cutting 27-45 mm.
Semi-professional power tools have a cutting depth of 50-55 mm and a blade diameter of 160-170 mm. As for the units of a professional level, they have a depth indicator of 60-100 mm and a disc diameter of 160-235 mm.
It is important to take into account that the larger the circular saw blade, the more expensive it will cost to purchase. Rotational speed
This criterion affects the permissible density of the processed material, as well as the cleanliness of the work process. The average speed for circular saws is 5500 rpm
Rotational speed. This criterion affects the permissible density of the processed material, as well as the cleanliness of the work process. The average speed indicator for circular saws is 5500 rpm.
It is best to choose a power tool with this speed or faster, whether it will be used in a home or professional environment.
Comparison with gasoline chain saws
For a correct comparison, you need to take into account the following parameters:
- Autonomy of use.
- Convenience of service.
- Reliability.
- Time of continuous work.
- Price.
In terms of autonomy, chain saws are inferior to gasoline ones. The area of their action is limited by the length of the "carrying". In addition, the electrical cable makes it difficult to work at height and requires constant attention (to eliminate the risk of falling under the circuit).
In terms of ease of maintenance, electric saws are superior to gasoline ones. All their service operations are reduced to infrequent replacement of worn out engine brushes, topping up oil and tightening the chain.
The more complex the tool is, the more likely it is to break. This rule is also true when comparing chain benzo and electric saws. In an electric saw, as the people say, "there is nothing to break." The performance of a gasoline analogue depends on a number of factors (the quality of the fuel-oil mixture, the cleanliness of the air filter, the condition of the spark plug).
Gasoline saws have a longer continuous operation time. The electric motor needs frequent stops to cool down (after 15-20 minutes). An internal combustion engine needs rest no earlier than 40-50 minutes after starting.
Price is an important buying argument. All other things being equal, a gasoline-powered tool designed for cutting wood is more expensive than an electric one.
Finally, we note that an electric drive is more environmentally friendly than a gasoline one. When working with an electric saw, you don't have to breathe in toxic exhaust fumes.
Features of operation and maintenance
The main condition for a long life and high-quality operation of an electric chain saw is a well-sharpened and tensioned chain.If we add to it the requirement for constant lubrication of the guide bar, then the list of operating rules will be complete. Since the chain tightening time coincides with the moment when the saw needs to be turned off to cool down, it does not bring discomfort to work.
The best indicator of the sharpness of the saw teeth is sawdust. As long as they are large, you don't have to worry about sharpening. As soon as their size decreases, you need to turn off the tool, remove the chain and take it to sharpening. Working with a blunt chain is not only physically difficult, but also harmful for the motor, which quickly loses its resource.
Regarding the operation of the chain, the masters give this advice: for work you need to have two saw chains, periodically changing them for even wear of the drive sprocket. When its teeth are engaged and the saw chains begin to slip, they acquire a new set.
After installing the new chain, the saw is allowed to run for 2-3 minutes, after which the tension is checked. To do this, take the chain with two fingers in the middle and pull it up. If it comes out of the "stream" of the tire by no more than 3-4 mm, then the tension is normal.
