In the backyard or cottage can not do withoutimprovised tools. Even for elementary harvesting logs need an ax and a saw, and even to create powerful units hozpostroek required, for example, a chainsaw. According to statistics, it is chosen more often than electric models, because there is no reference to a power source. But petrol units are so different in configuration and the weight that it is difficult to determine the specific model. Let us examine together, how to choose a chainsaw for their own needs.

Where chainsaw will be applied
Abilities chainsaw, its power and weightdesigned for different areas of application unit. Manufacturers produce three groups of instruments, each of which copes with a specific task, so you should decide before choosing a chainsaw that she will do in your area and how often.
Saws for small works on a garden site
The lowest power units are amateurclass. They are designed for batch operation, which is not more than an hour a day. Most chainsaws this group have up to 2 kW of power that affects their weight. These models are easy to lift, hold suspended. At the same time you will not feel the vibration of the tool, as it dampens the low-profile chain.
If you are the owner of the finished house or garden, andyour tool is needed to maintain order in the area, minor repairs, you should look at it in the amateur class chainsaws. Trim trees and prepare the wood, make the bench or sandbox - all quite capable of this machine. But your hands will not experience heavy loads, and will be able to control saw even an inexperienced host (or hostess!).
Semi-professional tool: to help in the construction of the house
Making a choice for chainsaw garden or home thatare at the very beginning of construction, it is better to draw the gaze to a semi-tool. They have a power higher than that of amateur units (2-3 kW), so all the construction work related to the timber, you can safely trust them. For example, the workpiece rafters, cutting boards for flooring, paneling timbers houses, etc. The main thing - not "torturing" the unit all day, because it is not designed for 8-10 hours of continuous operation.
Weight semi-model - about 6 kg.
When the rough construction is finished, the saw you will need to care for the garden or when landscaping.
Saws professionals: bring down the forest around the clock
The most powerful class chainsaws - professional. They are designed for organizations that are engaged in felling and cutting of trees on an industrial scale. For this work you need a tool that can cut a lot of hours, and in the most difficult areas, thick and gnarled trees. Therefore, the relevant professional chainsaws power - from 3 to 6 kW. This "beast" is designed for 1,8-2 thousand. Hours, slowly wears out and strongly roars.
In most cases, the choice of such a chainsawhigh-end for personal use is not justified. Professional models are difficult to manage. They strongly vibrate at work and weigh a lot (more than six kilograms). If the owner does not plan construction of log-built (eg, baths) and does not use the oven heating for which you want to cut firewood, you pay a high price for being too power while also giving a strong strain on the hands is hardly worth it.
The optimal capacity of the unit for the holiday needs
To decide what to choose for chainsawcapacity, calculate how thick the wood you will upload tool. After all, the power of influence on how quickly sawed material, would not it be difficulties when working with hard and thick timber.
For gardeners, pick up tool for pruningtrees in the garden and simple work on cutting boards, enough chainsaw, which power up to 2 kW. On the construction of the house is well managed with a roof frame and floors in the Chainsaw 2-2.7 kW. Power over it will affect the ease of management, given the load on the hand, even though the full power of the tool you still will not use.
"Filling" chainsaw: a headset pick up the saw
In addition to power, on the usability of the toolinfluences its content, ie, headset, which includes a chain of tire, how to protect and so on. When purchasing a chainsaw, keep in mind that all the components and parts requiring replacement, you will have to buy from the same manufacturer. Saw headset other brands just do not come to your chainsaw. Therefore, buy a certain brand, that there was no problem finding stars, chains, etc.
How to choose a chain chainsaw: attention to the links of step
The proper choice of the chain depends on howyour drink will successfully cope with difficult trees and how much time to spend it. Available are models with three chain Pitch: 0.404, 3.8, 0.325 inches. These figures - the common designation, so drinking any brand will be in the instruction of these indicators.
With step 3/8 and 0.404 inches are available powerfulmodel of professional and semi-professional class. They can withstand many hours of stress and very thick wood. However, for cutting frozen or contaminated material, even this step is not enough. For such purposes, buy a separate chain created with carbide tipped.
The most running chain step size at summer residents - 0,325inches. Almost all amateur models are equipped with drinking is such low-profile chains. The move is good for short-term work. With long-term continuous use of such chain quickly tupyatsya.
The length and shape of the tire
Before choosing a chainsaw to testify,pay attention to the characteristics of its tires. It can be of different lengths. The instructions for a particular model is always the optimum length of the bus states than that can not be, because it will affect the engine performance. For example, the length of the bus is well cut thick wood, because the deeper bite, but if they saw them ready with a weak power, you will lose speed. The motor will have to expend energy to the crankshaft rotation, at the same time cutting the rate of lost, although the fuel burn more. So that excessive length of the bus can cause rapid wear of the engine.
It happens that the same are for power unitsTyres of different lengths. Preferred for the holiday needs to take, where the tire is shorter. It will work faster and for stems of garden trees and not thick planks of its forces would be enough.
Besides length and analyze tire shape. So, for amateur models are narrow flat tires, which are equipped with low-profile chains and advantageous because it does not give a kickback. Such units are extremely safe, which is important for first-time users.
The second option tires - lightweight. They are so named because they weigh less than normal, and are designed to work at height. On the roof of the house more comfortable working light chainsaw. Lightweight sawbar represents 2 steel plates which are secured within the polyamide.
The third option tire has a replaceable head. This is necessary for chainsaws working in emergency mode on the felling, when the wear rate increases mechanisms. this form does not need tires for domestic use.
Protection and Security Settings
The protective mechanism that increases the level of security when working with a chainsaw, includes the following devices:
- Vibration protection
If no such protection, the at frequentusing the tool will start to hurt the joints of hands. So see how the fuel tank is located in relation to the motor. Ideal, if they are at the maximum distance. Then chainsaw weight is distributed more evenly. The mite introduced and the rubber gasket. They are placed between the body and arms.
- Protection against kickback
When cutting wood, it may happen that the sawOnly grab the barrel end of the bus, why will rebound on him who keeps the tool. As a result, there is a risk raspolosovat his face, shoulders and other body part that gets into the path of the saw fall. To avoid this, put a chainsaw to the two types of protection: the brake and flap.
The first variant is more common. It is a small lever that, when run leans closer to hand, and in the case of kickback brush it automatically presses.
Shields put on the end of the blade, so that when it bouncesIt was isolated. But this element you will not find in chain saws Swedish brand, because there are tools loggers officially end when felling.
