To the reader
The Service Manual for the HATTAT A90, A100, A110 tractors is intended to be a practical reference source to be used in
workshop.
The repair instructions in the manual are based on methods which have been worked out in practice during normal
workshop conditions and which are based on the use of special tools from the manufacturer when stated in the
instructions. The manual also contains descriptions of the design and function of the components.
Detailed maintenance instructions can be found in Operator’s Manual.
The Service Manual will be continually updated with new revised pages which should be inserted in the manual. Alterations
and additions will first appear as service bulletins.
Only genuine Hattat Tarım spare parts should be used to ensure the best possible function of the machine. Certain
operations should be carried out with the aid of special tools designed by Hattat Tarım .
