This paper presents the results of research of efficacy of the lightweight   low power chainsaw Stihl MS 260 in the operations of juvenile thinning in   preserved even-aged mixed stands of pedunculate oak with hornbeam, ash and   other hard hardwoods. The investigations were carried out in the territory of   FE “Sremska Mitrovica” in three sample plots of different ages. It is the   first research of this kind based on the choice of optimal technological   solution for the cleaning cuts of oak stands. Technology of work is based on   cutting unwanted species at a certain height in order to favor pedunculate   oak as the main species. In sample plot 1 the cutting through of undesirable   species was carried out in one place and then third parties carried out their   processing and transportation. In sample plots 2 and 3 workers cut the   unwanted species in several places and stacked the timber on the ground so as   not to interfere with the growth of pedunculate oak which does not tolerate   shading. In this study, we applied time and work study. Group system of work   was recorded. The group typically consisted of 4 workers and a foreman. Fuel   consumption was recorded by the method of tank refuelling. The research   results show that operating conditions have a significant impact on the   effects of work with a chainsaw, as well as on the consumption of fuel and   lubricants. The differences are mainly caused by different structures of cut   timber
