Chain saws on wood look like gasoline ones, but for network models, power is supplied from a single-phase power supply: the tool is connected to the outlet via an electric cord. Such an electric saw can work for a long time - this is an excellent option for work in the workshop or for the preparation of firewood in everyday life. If you need to move around the site with the tool or carry out dismantling work at heights, a cordless power saw is convenient.
In addition to the type of power, electric saws differ in the location of the engine. Models with a longitudinal arrangement differ in good balancing, with a transverse one - they are convenient when working in a vertical position of the tool. As an important design feature of the electric saw, you can highlight the chain brake, which is triggered by jamming of the chain and the threat of a reverse blow.
Depending on the area of use and upcoming tasks, choose an instrument of suitable power. Electric models for domestic use are equipped with engines up to 1000 - 1500 watts. A professional power saw can have a power of up to 2000 - 2500 watts. For cordless tools, the analogue of power is the battery voltage: 18 V - for small loads, 36 V - for intense ones.
How long the workpieces can be cut depends on the length of the tire. For small boards and logs, a model with a tire up to 30 - 35 cm is suitable. For large wood materials, it is better to choose a tool with a saw set up to 40 - 45 cm.
