A typical day covers everything from routine repairs and maintenance to engine overhauls.
There may be little differences depending on the company, but a technician will generally perform repairs, verify warranty where applicable, and diagnose vehicle malfunction. They document the work and ensure it meets standards. They can take vehicles for road tests for quality assessment outside the workshop. They maintain a neat and orderly work area in the workshop and ensure the customer's vehicles are clean after repair work.
Two days can differ, but the tasks and duties are universal: at the workshop or in the field. The nature of work is demanding and may require the use of physical strength apart from concentration and attention to detail. It involves moving, sitting, standing, stooping, and bending for long periods, and the technician must be able to work on simple and complex heavy-duty engines to be successful.
