Causes of defects of power chainsaws

Abstract The article presents results of one-year long observations concerning the main causes of failures of power chainsaws of various manufacturers. The observations were conducted at two authorised service repair shops. It was found that new chainsaws subject to free guarantee surveys constituted the highest number of serviced devices. On the other hand, the principle causes of defects included: the feeding system and the body as well as the piston-crankshaft system (total of 50% of defects). The smallest number of defects was recorded in the case of the exhaust system followed by the starter system and elements of the work safety. The majority of defects resulted from the application of improper use of operational materials, incorrect usage and inadequate knowledge of users as well as discrepancies between the intended application of the analysed equipment and real operational conditions.
