Peel - an essential tool for each summer residentand the private owner of the house. Even for firewood in the grill and then I needed her help, not to mention the cutting of trees and the construction of pavilions, terraces, etc. And if previously used handsaws and hacksaws, then, thanks to progress, now have the opportunity to acquire an excellent gasoline saw. The only question is what kind of, as a model that is suitable for intermittent operation, is unlikely to survive the whole process of the construction of a log house or a wooden bath. Here's how to choose a chainsaw considering the intensity of use and ease of maintenance.
Most low-power class chainsaws - amateur. It presents a model that will stand only periodic use of no more than 40-45 minutes a day. Typically, power chain saws household does not exceed 2 kW. They are low-profile chain, reducing vibration during operation. However, and performance of such chains is weak.
To support the order in the garden and periodic firewood for the fireplace is enough to buy a low-power consumer chainsaw
They are lightweight, easy to use, do not give a strong stress onhand and well suited to the needs of country: firewood, pruning, small-scale construction work. To fully built private house or villa, where repair work is carried out only occasionally, as well as to maintain order in the garden of this class enough chainsaw.
This class includes models which possesssufficient capacity and are able to work both on felling and on the construction site. The only negative - are not designed for long-term use, ie, if you do, then this tool will serve to cut short to 10 hours daily. Power semi units ranges from 2 to 3 kW, though preferably 2.5 kW. stem diameter - 40 cm Weigh like chainsaws 5-6 kg..
Ideal for the person who startsbuilding your own home, where a lot of work on the wood, creating a roofing frame Coanda floors, etc. And even after the completion of construction they will be indispensable helpers in the garden and on the site.
The novice developer will help in the construction of the house semi-professional chainsaw
The most "strong" class - the professional model,having a large capacity (2,7-6 kW) and capable of many hours of daily load. It is unlikely that the choice of this class chainsaw justified for personal use, unless the owner has no plans to build a log house, and after - a bath, and even himself to cut firewood for the house for the winter. As a rule, professional models are buying organizations engaged in felling, because the blade is very wear-resistant, can withstand about 2 thousand. Hours and are designed to work with thick trees.
The capacity of the professional chainsaw for the usual summer resident zamnogo
At home, without professional skillsto cope with such a saw is not easy: it has a high level of vibration (and therefore productivity is high!) and considerable weight - more than 6 kg. This puts considerable strain on the hands, especially for those who have no experience with such a tool.
Power - this is the main factor influencing thethe ability of the tool to cope with the heavy tree, cutting speed and possible depth. In order to understand their needs, move the estimated load on the tool head. If you do not plan to cut thick logs, operate the instrument on a daily basis, and choose the assistant for horticultural purposes, the power up to 2 kW will be enough with a vengeance. For personal settings suited chainsaws with capacities from 2 to 2.6 kW. Remember: the more power the unit has, the harder it is. And to cope with them will not be easy.
Now consider the nuances of the selection unit based on the capabilities saw sets.
It meets three types of guide bars:
- Narrow flat. They are placed on household chainsaw, which willuse non-professionals. A narrow tire is paired with a low-profile chain and has almost no such disadvantage as a reverse punch (say about him later). This is done to minimize the possibility of injury when using the tool.
- Lightweight. These tires are made of steel and areconsists of two plates between which is packed with polyamide. This design is specifically designed to reduce the overall weight of the unit, which is quite a significant impact on the quality of some works. For example, cut at the height of such a tool is much easier than usual.
- With interchangeable heads. This professional-grade tire designed for high-power saws, which are open every day for many hours.
Long tire suitable for sawing large trees, and short work with greater speed
In addition to the type of tire, pay attention to its length. It must be consistent with the capacity of the engine. Long buses are more comfortable with a thick tree, because you can make a cut deeper. But if she Packaged with a low-power engine, its power will not be enough to fast cutting, because the need to expend energy on the crankshaft rotation. You will be cut slowly and gasoline will more than usual, and the motor instantly wear out. The instructions to the saws must be specified the recommended option tire length. It can not be exceeded. The smaller size - are allowed. By the way, if there is a choice between two models of the same capacity, the small trees or better to take the boards, in which the tire is smaller because it higher cutting speed.
On the cutting speed and the ability to cope withheavy timber affects the chain pitch. To determine which chainsaw is better, you should know that three-step chain is found: 0.325 inch, 3/8 inch and 0.404 inch. This is a common notation for all producers, therefore, analyze the features of the circuit to each of these parameters.
Chain pitch is selected based on the power chainsaw
Step into 0.325 inches have everyday low profilechain. This is the optimal size for short-cutting, because the different low vibration. Long-term stress such a chain would break down and instantly becomes blunt.
The chainsaws are powerful chain or 3/8 increments0.404. They are able to work for a long time and saw the thick trees. But even these units are not designed to work with the frozen and dirty wood. For such purposes are produced chains having tipped.
When replacing any part of the saw sets we need to look at the detail of the same manufacturer
Keep in mind that buying a chainsaw, youautomatically become a "fan" of the brand, because the components saw sets from different manufacturers do not match each other. Those. sprocket, sprocket, bar and chain must be released one plant, and when damage is necessary to search the item of the same brand, or you simply do not collect the kit.
In the process of working with the most dangerous toolthe phenomenon of the so-called "kickback", ie saw a rebound in the direction of a man who works with her. Kickback may occur when a tree hit the very end of the bus. And when choosing a tool, better check if there are models you are interested in this phenomenon of protection.
Protection against "kickback" will help inexperienced operators to avoid injury
Protection is of two types: using a special or additional brake flap. The brake is more common. It looks like an arm-guard that can switch in position 2. When the tool is run, arm position becomes "closer to the hand," and when there is a "kickback", the hand automatically presses the lever, and that translates to a position immediately stops the chain movement.
Additional panel created to handthe operator does not come into contact with dangerous machinery, the saw in operation. He put on the headset and end the guide called defensive sectors. This protection is not found in Swedish chainsaws, as in this country loggers used tires at the end of the forest cutting. And it is officially allowed.
In the selection of the saw certainly ask the sellerturn it on and hold in their hands. Light household saw not strongly vibrate, but if they have a rubber gasket, it has a positive effect on the quality of work. Located such spacers between the arms and the body of the unit. The powerful models of the engine and the fuel tank must be separated from each other, so that the unit weight is distributed evenly on the entire structure.
Chainsaws without protection suit only those who work rarely and briefly. The longer a tool in the hands of the stronger impact vibration on the hands that will eventually lead to diseases of the joints.
It happens that some of the works on the siteWe have to deal with and for women. And if we analyze what is the best chainsaw for female hands, then, should be chosen from the group undoubtedly only low-power amateur units, because they weigh little and slightly vibrate. On the powerful forces model of female hands are not enough.
For weak female hand fit only low power household model chainsaws
But if there are no problems with electricity, it is worthgive preference saws. With it, and easier to manage and easier to maintain:. It is not necessary to change the oil, pour gasoline, etc. With such a unit to handle even the skinny lady.
