Abstract The chain-saw is one of tools commonly used for professional work in the forest and home yards. While working the tool is a source of considerable noise. Experiments on vibration and noise damping abilities of mineral and vegetable oils were carried out at the PIMR – Industrial Institute for Agricultural Machinery in Poznań. The experiments were conducted on a specially constructed measuring stand. The chain saw was running along the bar, while no wood was being cut. Noise was measured with a Bruel & Kjaer meter at a height of the longer symmetry axis of the bar, when the bar plane was vertical and the symmetry axis was horizontal. Measurement results showed that noise levels observed were high and varied with oils used, ranging from 99.6 dB(A) for one of the vegetable oils to 105.2 dB(A) for a mineral oil.
