Chainsaws are the most basic mechanical tools used to harvest and pre-treat wood. Unfortunately, these devices emit noise and vibrations exceeding the maximum permissible levels for an 8-hour working day. Many factors influence the level of noise and vibration emitted by chainsaws. Since the conscious choice of the saw chain can significantly contribute to: productivity increase, vibration reduction and the operator's permissible total exposure time extension the influence of the type of a cutting tooth and its wear on the vibration level recorded on the handles of the device has been investigated in this paper.
