Chainsaws are devices that exhibit intense dynamic effects. Their duty cycle can be divided into several stages. In particular: start-up, operational run and run-down. During each stage the engine unit is connected to or disconnected from the working part through centrifugal clutch. When driven by internal combustion engine, the unfavourable vibrations occur at the handles due to unevenness of its run. Chainsaw manufacturers pay special attention to emergency braking in critical situations. Time necessary for chain to stop from encountering the first emergency trigger is taken as a measure of effectiveness of the breaking system. To assess specific chainsaw systems, it is necessary to create detailed computational dynamic model.

Keywords: Chainsaw, Dynamic conditions, Starting, Emergency braking
