The chainsaw has to combine such qualities as safety, durability, mobility and convenience during the work. The modern market offers wide choice of similar tools, but it is impossible to tell that their quality is at the high level. It is necessary to select the chainsaw according to certain criteria.
Criteria for selection of the chainsaw
First of all it is necessary to define for what purpose the chainsaw is necessary for you. It is important when choosing the tool the forthcoming volume of the performed works. If you use further saw in household (for cutting of branches in garden or preparations of firewood for bath), then it is the best of all to choose small model. The resource of such tool is limited, it is not intended for performance of large volume of works.
Irrespective of producing country and brand of the chainsaw are divided into four categories. Household saws are characterized by the low power and modest dimensions, are intended for small operating time (till twenty o'clock in month). One-handed chainsaws are used in park economy, gardening. Operating time of semi-professional model much more, the tire length, power and resource of work are sufficient for daily works in economy. Professional saws are characterized by big resource of engine hours, have big capacity, can work till sixteen o'clock in day.
Time of cut is not less important characteristic when choosing the chainsaw which depends on power, the correct selection of chain and also its correct sharpening. It is necessary to mention in this characteristic arrangement of the engine of the chainsaw. Stop the choice on model with longitudinal arrangement of the engine, otherwise you risk to get saw with the displaced centroid and it is necessary to level the line of cutting constantly. It is extremely inconvenient and time of cut increases.
Power and vibration characteristics
Power of the tool depends on the motor and type of the chainsaw. Professional tools (in comparison with household) have big power. It is unlikely you have need to get saw in 6 horsepowers for periodic cutting of trees or branches. For the household tool will be the power of 1.7-2 kW enough. Than power is more, more than the engine displacement and mass of saw will be that. It is necessary to approach vibration characteristics on which the further convenience of work with the chainsaw depends attentively. The anti-vibration protection at model is higher, the work and less fatigue are easier will test your hands, the best quality of cut turns out. The handle and the engine case in the high-quality tool have to be separated from each other. It is desirable that the fuel tank has been combined with the handle, in this case energy of vibration is spent for the mass of tank. The best check of reliability of anti-vibration system – start of the chainsaw in your hands before purchase.
