Chain saws are divided into gasoline saws, electric saws, pneumatic saws, and hydraulic saws according to the same source. The four types of power saws have obvious advantages and disadvantages:
Gasoline saw: strong mobility, suitable for field mobile work. However, the noise is high, the maintenance is troublesome, and the heat production is more.
Electric chain saw: stable power, fast start, bulkier 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 and light weight. However, an air compressor must be attached, which increases the area and is subject to conditions.
Hydraulic chain saw: full power, but slow start and smooth operation. The hydraulic pumping station is smaller than the air compressor. higher cost.
