Abstract

Chainsaw is the main tool for work in a phase of wood felling and processing of forest harvesting in BiH. The aim of the research was to determine fuel and lubricant consumption of the chainsaws Husqvarna 365 and Dolmar PS – 7310 in the phase of felling and processing of wood assortments at the area of P.J. Forest Office „Zavidovići“, forest compartment 203. The volumetric method was applied for the measurement of fuel and lubricants consumption, with precise determination of fuel and lubricant quantity in chainsaw tanks. In total 140 trees of the sessile oak were felled (70 trees with
chainsaw Husqvarna 365 and 70 trees with chainsaw Dolmar PS – 7310) during the research. The diameter at the breast height of felled trees ranged from 15 to 84 cm, while tree height ranged from 10,3 to 37,2 m. The total volume of processed assortments was 180,11 m3. The average fuel consumption per m3 processed assortments was 0,306 L/m3 for trees felled by chainsaw Husqvarna 365 which is for 0,042 L/m3 larger in comparison to chainsaw Dolmar PS – 7310 with average fuel consumption of 0,264 L/m3. The average lubricant consumption per m3 processed assortments was 0,102 L/m3 for trees felled by chainsaw Husqvarna 365 which is for 0,012 L/m3 larger in comparison to chainsaw Dolmar PS – 7310 with average lubricant consumption of 0,09 L/m3. Considering conducted research it can be assumed that there are differences in fuel and lubricant consumption between this two type of chainsaws for considered working conditions, but differences are not statistically significant.

The aim of the research was to determine fuel and lubricant consumption of the chainsaws <i>Husqvarna 365</i> and <i>Dolmar PS – 7310</i> in the phase of felling and processing of wood assortments at the area of P.J. Forest Office „Zavidovići“; forest compartment 203. The volumetric method was applied for the measurement of fuel and lubricants consumption; with precise determination of fuel and lubricant quantity in chainsaw tanks. In total 140 trees of the sessile oak were felled (70 trees with <br>chainsaw <i>Husqvarna 365 </i>and 70 trees with chainsaw <i>Dolmar PS – 7310</i>) during the research. The diameter at the breast height of felled trees ranged from 15 to 84 cm; while tree height ranged from 10; 3 to 37; 2 m. The total volume of processed assortments was 180; 11 m³.
