1. According to the classification of chain saws, it can be divided into large, medium, small and micro according to the power of the initiator. Those with 4.4 kilowatts or more are large; those with 3 to 4 kilowatts are medium; those with 1-2 kilowatts are small; and those with 1.5 kilowatts or less are micro.
According to the type of saw handle, it can be divided into two types: high-handle chain saw and low-handle chain saw. The weight of the high-hand chain saw is evenly distributed on both arms, and it is convenient to carry. There is no need to bend over during operation. The machine is easy to maintain; the low-hand chain saw is compact in structure, light in weight, and has less vibration during operation. It is suitable for stopping in mountainous forests.
