The machines in this handbook are designed essentially for agricultural and associated applications. This is their intended use. Any modifications made to the machine without prior written approval from CLAAS or if the machine is used in any way contrary to the intended use or if the machine is not properly driven or maintained then the Company will not accept any liability whatsoever for any damage or injury (whether direct or consequential). The method of operation and maintenance specified in this handbook should be strictly adhered to. For your parts requirements, it is essential that only genuine CLAAS parts are fitted. Any resultant damage from non-genuine parts will invalidate your machine warranty. CLAAS operates a policy of continuous improvement to its products and reserve the right to change specifi- cations and equipment without notice. Therefore some information within this handbook may differ from your machine.
