Preface:
These operating instructions have been written for the machine operator and for the maintenance personnel of the machine.
They contain:
– The technical data.
– The safety requirements.
– The operating instructions.
– The maintenance instructions.
The operating instructions are to be read and used carefully by all persons who carry out work with or on the machine before putting the machine into service for the first time and later, at regular intervals.
Work with or on the machine includes, for example:
- Operation including setting up and equipping, rectifying malfunctions during the course of work, resolving production dropouts, care, disposal of operating and process materials.
- Maintenance, including maintenance, inspection and repair work.
- Transportation or loading the machine.
The operating instructions allow the machine operator to familiarize themselves with the machine more easily and prevent malfunctions occurring due to improper operation. The observance of the operating and maintenance instructions by maintenance personnel:
- Increases reliability in use.
- Extends the service life of your machine.
- Reduces repair costs and downtime.
The operating instructions belong with the machine for the entire lifetime of the machine. Place a copy in an easily reached position on the cab storage shelf. This copy must be replaced immediately if lost, damaged or unreadable.
The operating and maintenance instructions must be completed by information on current national regulations for accident prevention and protection. In addition to the operating instructions and legally binding regulations on accident prevention which apply in the user country and at point of use, authorized specialist rules for safe and correct working procedures are also to be observed.
These operating and maintenance instructions contain all the information required for operating and maintaining your machine.
- Some illustrations in these operating instructions may depict details and working devices which differ from your machine.
- In some illustrations, protective devices and covers have been removed in the interests of better presentation.
- Improvements, which are always being incorporated into our machines, may result in changes to your machine which are not yet indicated in these operating instructions.
