How To Choose A Good Chainsaw For Home
The most common class of chainsaws is amateur.
The models presented in it can withstand continuous work only for a few hours a day. Usually the power of household chainsaws is 2 kW.
The chains on these models are low profile and reduce vibration during operation. But the performance of such chains is much lower.
Amateur chainsaws are very convenient and ideal for summer cottage work: harvesting firewood, pruning trees, solving small construction problems. For a country house or summer cottage, as well as for order in the garden, such a chainsaw will be enough.
Kick back this is the rebound of the saw when working towards a person. Kickback occurs when the end of the tire hits the tree. When choosing and buying a saw, be sure to check if the selected model has protection against this phenomenon.
Chainsaw protection against kickback goes two types:
- Using a special brake;
- With an additional shield.
Chainsaw brakes are much more common. It looks like a flap lever. When the tool is operating, the lever is set to the closest position to the hand, and with a reverse impact, the hand will automatically press the lever, and it will be transferred to the stop position of the chain movement.
An additional guard prevents the operator’s hands from touching dangerous machinery while the saw is in operation. It is installed at the end of the saw headset. This protection is not available on Swedish chainsaws.
Choosing a good and inexpensive chainsaw for summer cottages and houses: Tips Tricks. Overview
Chainsaw this is the right tool for the summer resident and gardener. In a private house, such a tool also does not hurt. For example, for preparing firewood for a stove and barbecue, pruning trees and building gazebos, etc.
Previously, only hand saws and hacksaws were used, but thanks to technical progress, today it is possible to purchase an excellent chainsaw.
When choosing a tool, the question will certainly arise, which chainsaw to choose for a summer residence? And which chainsaw to choose for building a house?
The fact is that a model for periodic work is unlikely to cope with the construction of a wooden frame. In our article, we will take a closer look at how to choose a chainsaw for the home, taking into account the frequency of its use and ease of maintenance.
When choosing and buying a chainsaw for your home, ask the seller to check it and hold it in your hands.
Light amateur saws should not vibrate too much. To reduce vibration in such chainsaws, rubber gaskets are installed. They are located between the handles and the saw body.
In professional power saws, the engine and the fuel tank are separated from each other to evenly distribute the total weight over the entire structure. Chainsaws without special anti-vibration protection are suitable for those who work for a limited time.
The longer you work, the more vibration will affect your hands, and this will lead to inevitable joint disease.
How to choose a tire for your chainsaw?
Exist three main types of saw bars:
- Flat, narrow. They are put on amateur chainsaws. A narrow tire is usually paired with a low profile chain and has no kickback. This is necessary to reduce injuries when working with this chainsaw.
- Lightweight tires. They are made of steel, they are two special plates with polyamide packed between them. This design significantly reduces the overall weight of the chainsaw. And it becomes much easier to work with such a tool.
- A tire with replaceable heads. Installed on professional chainsaws, with high power, which work continuously for ten hours a day.
Long tires make it easier to cut thick wood as the cut is deeper. But if such a tire comes with a low power mechanism, then its power will not be enough for fast sawing. You will start sawing more slowly and the chainsaw motor will wear out instantly.
All instructions for chainsaws indicate the recommended tire length. This figure cannot be exceeded. You can reduce the size.
And if you have a choice between models of the same power, then for a small volume of wood and boards it is better to choose a chainsaw with a smaller tire, since its cutting speed will be much higher.
What oil to choose for refueling a chainsaw?
The oil is selected depending on the type of engine: for 2-stroke and 4-stroke models. Most chainsaws have a two-stroke engine: if air cooling is used, any oil marked 2T will do, if the liquid is TC-W3.
Quality is of the utmost importance: poor quality grease forms carbon deposits on the piston rings and cylinders. This leads to seizure and overheating.
When choosing, you should take into account the seasonality: mineral oil hardens in the cold, it can only be used in warmth. At the beginning of frost, you can use semi-synthetic oil, when working in winter, exclusively synthetic. There are also biodegradable lubricants on the market that are a great option for those who care about the environment. If a little begins to thicken, it can be diluted with kerosene in a ratio of 1: 4.
Saw won’t start
- There is not enough fuel or its supply is difficult (you need to check the hoses and the fuel filter);
- Problems with the spark plug it’s time to replace or clean it.
- The breather element, which is located on the cover and is responsible for equalizing the pressure, is dirty. The hole can be cleaned with a regular needle.
- Clogged muffler or exhaust valve.
- Need to debug carburetor.
Which gasoline is best for the saw?
For chainsaws, AI-92 gasoline is best suited: it is this octane number that is best suited for garden equipment. Old saws (Friendship, for example) can be refueled with AI-80 gasoline: their engines are unpretentious in terms of fuel quality. Contrary to popular belief, expensive fuel of the AI-95 and higher class will not be beneficial: when turned on, the piston is pushed into the counter-duct and burned.
It is not recommended to fill in fuel that has been in a plastic canister for a long time: due to evaporation, beneficial properties are lost, which can lead to problems during starting and a rapid drop in power.
How to sharpen a chain?
In order to increase the resource of the chain, it must be sharpened regularly: the more the teeth have had time to grind, the more material will have to be removed. It’s time to sharpen the saw blade when:
- You have to apply more forces to cut;
- Fuel and oil consumption has increased;
- When sawing, small chips are formed instead of coarse ones.
Depending on the original geometry, the teeth need to be sharpened at a specific angle. Front corners are sharpened at 60-85 for quick plunge, rear corners at 50-60 for easy glide. The sharper the angle, the faster the cutting of softwood; when working with hard and frozen rocks.
Every 5-10 sharpenings, it is necessary to file the depth gauge: that the recoil and vibration did not increase.
For work, you can use the following tools:
How to choose a tire for your chainsaw?
The cutting depth depends on the length of the bar. It is selected in accordance with the tasks ahead and the power (a low-power motor will not pull a long tire). often the length of only the working part is indicated in inches or centimeters.
You should also take into account the width of the groove and the sprocket pitch, the distance must match the parameters of the saw. It is best to use original chains and bars from the same manufacturer.
Adequate quality lubricant will help prevent premature wear and overheating.
A little about the design and principles of operation of chainsaws in general
Each saw powered by energy from gasoline runs on a gasoline two-stroke engine, which is actually the starting link for spinning up the chain mechanism capable of sawing thick wood and other non-fragile materials. In addition to these two important components, the chainsaw has in its structure:
- The tire on which the sawing component itself is held;
- Each chainsaw has a tank for storing its own gasoline fuel;
- To turn on the entire system, it is necessary to supply gas, and activate the starter using a special handle;
- The design provides a security system, a button that protects against accidental activation;
- Air outlet column;
- Of course, where there is a start, a finish is also needed, it is the chain brake lever.
How to choose a good chainsaw for your home
A saw for use at home, in the country, or in professional enterprises is a very useful thing, because what used to take half an hour, an hour, and for which sometimes two or three people were required, now you can cut one in a minute, you have only a portable one in your hands a circular saw running on gasoline. Today we will tell you how to choose a chainsaw that is suitable specifically for your tasks, and consider a little the principles of its structure and operation. You can find out detailed technical characteristics of portable chainsaws and make a good choice on the website https://dtv-instrument.com/ru/news/-rejting-benzopil-stihl.html. Well, let’s get started.
Which saw is best for your task
If you choose a tool for your home and garden, then professional decisions will be superfluous. The ideal option is a standard household gasoline saw, it has approximately the following parameters:
- Power reserve up to 2 kilowatts;
- Weighing no more than 4-5 kilograms;
- Tire length from 240 to 350 millimeters;
- Spacing of the teeth of the chain itself 0.325 inches.
This type of saw perfectly reduces vibration during work, and allows you to safely use it for 40 minutes a day. If you do not exceed this limit, then the purchase will serve you for many years. If you are looking for more professional solutions, they will have higher parameters and cost more.
Tips in the article “What are the advantages of natural tiles” here.
In addition to the increased power up to 3 kilowatts, the weight will increase by at least one kilogram, the bar length will be longer, and the sawtooth span will increase to 3-eighths of an inch. As a rule, such a saw is designed for several hours of work a day, and with proper care for it: when changing the chain, you should turn the chainsaw tire, such a solution will not only help to cope with repair work, but will also serve further helping in household problems.
Which brand to choose?
The choice of a brand depends only on the planned budget for the purchase, personal preference. Reliable chainsaws of different classes are produced by the following manufacturers:
The cost depends on the technical characteristics, power and configuration. All manufacturers supply the device in a cardboard box with a headset protective cover.
Chainsaw is a tool of increased danger, if used incorrectly, it can lead to injuries. Difficulties arise when you hit back. This is the moment the chain touches the solid surface, when the apparatus is thrown back. For protection, a special handle with a screen is installed on the models to stop the chain.
A structural part of the engine associated with the fuel system. Usually not indicated in instructions. It rarely fails, a characteristic sign of a breakdown is work only at idle. The features of the power plant are usually not taken into account when choosing a chainsaw model.
Design and principle of operation
Chainsaws are equipped with a carburetor internal combustion engine; in most cases, a two-stroke single-cylinder engine is used. The design can be conditionally divided into two parts, the machine body and the moving saw fixed on the rail (headset). The movement of the cutting chain is based on a centrifugal type clutch. In most models, the couplings are designed in such a way that when the chain is jammed, the engine does not shut off, this increases the service life and smooth operation.

Weight and dimensions
Household models are lightweight, which lightens the burden on the hands and simplifies light work. Professional chainsaws transfer the load to the hand, skill in use is required. The weight of amateur models does not exceed 3 kg, which is convenient not only for operation, but also for transportation. Felling saws can weigh over 6 kg.
The second important parameter when choosing a tool size is the length of the tire. This is the mechanism on which the chain is attached. Affects the maximum diameter when cutting wood. The main types of tires:
- 30-35 cm are suitable for cutting logs up to 30 cm in diameter;
- 40-45 cm are able to saw through a tree up to 40 cm at a time;
- Over 45 professional grade features, suitable for felling old trees from 80 cm in diameter.
When choosing a chainsaw, you should check the availability of chains for a specific tire on sale. In the future, this will make it easier to replace.
