Welcome to High Quality Store Chain Saws Collection
Whether it is pruning garden plants or extensive production, cutting timber or large logs, the chainsaw is the ideal tool to facilitate, improve and increase the efficiency of workers in the sector and not.
The invention of the chainsaw is due to the German Emil Lerp who, in 1927 on Mount Dolmar in Thuringia, after a long and arduous period of research, designed and tested the first prototype: it weighed 58 kg and required at least 2 people to be used.
Today, it is possible to use not only manual saws, but chainsaws powered by electric or fuel engines, to ensure precision cutting, halving time and effort.
How to choose a chainsaw
To select the chainsaw that is suitable for your needs it is important to consider the use that will be done, which varies from small gardening jobs to more professional use.
A chainsaw consists of a two-stroke engine powered by an oil-petrol mixture and a "guide bar" that serves to transmit the movement from the engine to the chain, which acts as a real blade. This is a chain similar to that used in bicycles; each segment of this chain has a small blade, called "tooth". Some models (less powerful but lighter) are equipped with an electric motor.
For a mainly domestic use, it is advisable to opt for models that are not excessively powerful (between 1.5 and 2 kW), usually lighter and more manoeuvrable. For a more intensive use it is advisable to opt for models of power and upper displacement, which allow you to section larger logs.
Depending on the type of cut that will be done with the chainsaw, there are models for pruning, for agricultural and forestry use and for the maintenance of particular plants. The difference lies in the chain: the thickness, can vary from 1.1 to 2 mm and the type of mesh can have rounded edges (ideal for occasional use) or straight edges, which last longer and improve performance. The number of links in the chain determines the length of the cut and is obtained by counting the links, ie that part of the chain that comes into contact with the bar and is shaped like a hook.
The cutting sequence can be of the standard type, with the greatest amount of cutting teeth possible to guarantee excellent cutting conditions, or semi-skip and skip; the latter are usually for hobby chainsaws, with lower cutting characteristics due to fewer cutting edges.
Use and maintenance of the chain saw
The chainsaw is usually used in activities such as cutting trees, pruning and cutting logs; it can also be used to open gates in structures (houses, cars, etc.) if access is difficult (use attributed to firefighters or competent personnel).
As far as maintenance is concerned, the chain saw must generally be lubricated with two different oils: one for the engine, mixed with petrol, and the other for the chain. In the first case it is the same fuel that lubricates the engine, as it contains between 2 and 5% of oil. The chain is instead lubricated with a special oil, characterized by a high viscosity that prevents the dispersion and not only helps the chain in sliding inside the guide bar, but also prevents overheating. The use of a wrong oil often causes damage to the saw; it could in fact cause the chain to detach from the metal bar, and it is very dangerous.
An operation to be carried out occasionally based on the amount of wood cut and its hardness is the sharpening of the teeth of the chain; this can be done with a special file or a semi-automatic countertop electric tool, equipped with emery grinding wheel.
