Danger due to Exiting Material!
According to accident prevention regulation of the
employer’s insurance association, persons allocated the
task of eliminating blockage must wear personal protective

and must position themselves such that they cannot be hit
by exiting material. Other persons may not linger around.
Turn the main reversal switch to position "0".

The main reversal switch is locked in position "0" by pushing the selection
slide (1) to the left as preset and thus the rotation direction is preselected.
If the switch is on the left, the switch can be turned back to zero, but it is
blocked in the right position.
