1 General information
1.1 Operating instructions
These operating instructions are valid for the machine named on the cover
sheet.
The operating instructions convey important notes for the safe and efficient
handling of the machine. It is part of the machine and must be kept in legible
condition and accessible in the immediate vicinity of the machine for the

2.7 Residual hazards
The machine was subjected to a risk assessment. The hazards determined
in doing so were, in as much as possible, removed and detected risks
reduced. But the machine still harbours residual risks which are described in
the following section.
The warnings and safety instructions listed in here and in the action chapters
of these instructions must be observed without fail in order to prevent
possible damage to health and dangerous situations.
Danger zones which cannot be avoided due to the construction of the
machine are marked with warning signs.
