One of the aims of maintenance services in modern enterprises is to achieve certain production efficiency. As a result of processes during the operation, component parts or elements of machines may wear and lead to shutdown of work. Thus, the achievement of necessary efficiency is obtained by proper planning of machine operation. The applied preventive approach – prevention rather than repair - requires the use of certain methods of failure analysis. The FMEA methodology adopted in the context of machines assessment is presented in this thesis. The case study is an assessment of selected components of the wood chaff cutter, in case of which operational reliability depends on identified factors. The Machinery FMEA allowed to create a list of potential sources of failure, which was especially useful to plan the range of service during inspection, a list of spare parts, the potential shutdowns caused by not applying to occupational safety and health rules were also emphasized.
