detect mechanical and electrical faults by using instruments that check charging and starting circuitry; batteries, ignition and ignition timing; fuel injection systems and speed control; cylinder compression, engine condition, braking efficiency, and wheel balance and alignment
repair and maintain the hydraulic components of diesel and petrol/gas engines that are used to power attachments such as hoists, booms, scrapers, buckets and augers
