The aim of the study course is to understand the essence and necessity of machine repair.In this course students acquire in-depth vehicle and agricultural equipment defect types, their causes, diagnostics and troubleshooting techniques. Get acquainted with the techniques for determining the technical condition and repair methods of vehicle parts and elements.
• Knowledge of the prevention of failures of vehicles and their units, repair options and equipment and materials used in the refurbishment process;
• Skills to determine the technical condition of vehicle parts, as well as the most effective techniques and means for restoring the performance of vehicles and their units;;
• Competence to perform technical maintenance and renewal of vehicles, to select equipment and tools appropriate for these works.
The knowledge and skills acquired in this course will be assessed by 3 tests, 1 independent task and laboratory works and their reports.

Laboratory work must be developed, defended and completed. All tests must pass a grade of at least 4.
Laboratory work must be developed, defended and credited.
Independent work must be developed and completed.
Exam.
Students develop independent work in the form of a concise description of vehicle engine failures, their diagnostics and repair techniques. The topic of the independent work is coordinated with the lecturer.
Test tests are counted if they score at least 4. The test evaluation criteria determine the number of points for each correctly answered test question.
Laboratory work will be credited if developed according to the requirements of laboratory work reports, and they successfully defended.
Independent work is evaluated with a mark.
The examination grade can be posted automatically if all laboratory works, independent work and all tests have been successfully completed and defended. The final assessment consists of the average assessment of the tests, independent work, as well as the assessment of the completeness and quality of laboratory work.
