The chain saw can be divided into gasoline saw, electric saw, pneumatic saw and hydraulic saw according to the same source. The advantages and disadvantages of these four power chain saws are obvious:

Gasoline saw: strong mobility, suitable for field mobile work. But it is noisy, troublesome to maintain and produce more heat.

Electric chain saw: stable power, fast start, heavier than other saws. But if the line is too long, it will be inconvenient to move.

Pneumatic chain saw: safe and pollution-free, low noise, light weight. However, the air compressor must be attached, which increases the floor area and is restricted by conditions.

Hydraulic chain saw: full power, but slow start, stable operation. The volume of hydraulic pump station is smaller than that of air compressor. High cost.
