Despite the increasing presence of modern mechanization, tree felling and timber processing using chainsaws still dominate forestry operations in Serbia, accounting for approximately 90% of the total harvested timber. This highlights the need for a more in-depth analysis of the ergonomic aspects of such work methods. The aim of this study was to assess the physical workload of chainsaw operators engaged in tree felling and logging processing in selection forests of beech and fir, using the OWAS method and the Lundqvist index, as well as to provide recommendations for improving these work practices. The results showed that the majority of body postures observed among the workers fell into the first two OWAS categories out of four. However, all workers involved in the study were found to have a borderline level of physical workload according to the Lundqvist index. Based on these findings, improvement measures were proposed, including better work organization and potential worker rotation, wherever feasible, in order to reduce the risk of long-term physical strain and adverse health effects -primarily damage to the musculoskeletal system (MSD).
