Main points of purchase
1, according to the classification of chain saw.
According to the power of the engine, it is divided into large, medium, small and micro: large above 4.4 kW; 3 ~ 4 kilowatts is medium; 1 ~ 2 kW is small; Everything below 1.5 kW is miniature.
According to the type of saw handle, it can be divided into two types: high-handle chainsaw and short-handle chainsaw. The weight of the chain saw with high handle is evenly distributed on both arms, which is easy to carry, and it is not necessary to bend over when working, so the machine maintenance is simple; The short chain saw has compact structure, light weight and low vibration when working, and is suitable for comprehensive cooperative industries such as stopping cutting, pruning and timber making in mountainous forest areas.
2, according to the shape of the saw chain to choose
There are two kinds of saw chains: straight tooth type and angle steel type (universal type). Straight-toothed saw chains are suitable for cutting wood. Angle steel saw chain can stop cutting wood horizontally or obliquely, and it is simple to manufacture. Filing is simpler than straight tooth saw chain, and it is a widely used saw chain type.
Wood-inserting teeth are the supporting points when the chainsaw saws wood. The local force of the chainsaw and the reaction force when the chainsaw saws wood act on the wood itself, which increases the rest intensity of the operator. For ease of operation, the chain saw is also equipped with a control device including a saw handle.
3, according to the budget to choose
Of course, if the budget is low, you can choose to buy a hand saw or even an axe, but if the task is big and the hand saw can't meet the demand, you should choose a chainsaw and a chainsaw. There is no doubt that chainsaws can be recharged. This is regional. The chainsaw burns gasoline, which can be taken to the wild at will.
Because of charging, the power of chainsaw is relatively small, and it is generally used to cut wood with smaller diameter. Because the chainsaw uses gasoline, it has high power and sufficient horsepower, and it can cut large-diameter trees. Because of the difference between gasoline and electricity and the price of the machine itself, the cost of chainsaw is lower than that of chainsaw.
