1. Using the operating instructions
1.1 General
This operating manual (OM) introduces the Band Saw BS 820 and explains
how to use it properly. The document takes you, as the reader, through the life cycles
of the machine and shows you, among other things, how the machine can be operated
and serviced safely and economically.
In contrast to drawings and details in this OM, the company reserves the right to make
technical modifications that are necessary to improve the machine or the assembly.
The “Meyer Burger AG” company name is abbreviated in this document to “MB”.
Note: In addition – this OM must be kept at the machine’s installed site at all times.
810002683-en-00BS 820 - Using the operating instructions
1.2 Target group
The OM must be read, understood and all points complied with by all persons
who are tasked with the following work with or on the machine:
■Operation including preparation, trouble-shooting during the working sequence,
removal of production waste, care, disposal of process materials
■Servicing (maintenance, inspection, repair)
■Transport
1.3 Assessing the operating manual
When drafting this OM, we carefully applied standards DIN 62079 (VDE0039)
and EN ISO 12100-2. Despite our efforts, experience tells us that an OM is not a static do-
cument – it is a living document and is experienced by others.
Please let us know of any suggestions for improvements to or comments about this OM!
Every contribution is welcome and will be reviewed by us.
Thank you in advance for your contributions.
