• This service manual consists of independent chapters dealing with both technical and assembling data, adjustment instructions and the guideline how to use special tools, jigs, fixtures and aids.
• The main purpose of this manual is to provide basic information for assembly, dismantling and service repairs of main assemblies of the machine.
• The unit assemblies are marked in this manual in the same way as in the spare parts catalogue.
• Before the dismounting, we recommend you to mark the parts disassembled keeping in mind the way how they will be put back and to blind all holes of the hydraulic system to prevent contamination of hydraulic circuits.
• During assembling the parts to the machine, tighten each bolt or nut according to the tightening torque table (Chapter 13.6.) if it is not stipulated otherwise in the text.
• Always follow safety regulations and measures shown in Chapter 2.
• The manufacturer is continuously improving his products on the basis of operational experience and latest developments. He, therefore, retains the right to make changes, on the basis of research and development, as compared with Figures, descriptions, procedures and designs given in this manual.
• Terms such as in the right-hand, left-hand, front or back are used in this manual for the customer’s information – that means when the machine goes forward.
