This workshop manual provides notes for trained technicians to maintain our tractors. Read and observe the information in this documentation. This will help you prevent accidents.
Intended use includes maintaining operating the service and maintenance conditions as specified by the manufacturer. Operation, maintenance and repair of the tractor may only be carried out by people who are familiar with this equipment and aware of the associated dangers. Ensure that this documentation is available to and understood by everyone involved in operation, maintenance and repair. Not observing this documentation
can lead to faults, damage and personal injury.
The prerequisite for the Fendt 818, 820 Vario COM III tractor being correctly serviced and maintained is the perfect condition and availability of all necessary equipment, standard tools and general workshop equipment as well as special tools. Special tools must only be used where absolutely necessary. The tools are displayed where they need to be used in each case.
The machine must be maintained according to its proper use. Always replace parts with genuine FENDT spare parts! When ordering parts, please provide the chassis number as per the most up-to-date spare parts documentation.
Workshops should also refer to documentation on maintenance work and technical data. Once maintenance is complete, take a test drive to ensure the vehicle’s correct operation and road safety.
The model table distinguishes chassis 729 and 731, each starting at 1001-. Auto-Guide testing instructions, Greentec system documentation, technical data and repair schedules are separate publications.
