Notes on adjusting
All adjustments in these adjustment instructions are based on a completely installed
machine and must only be carried out by appropriately trained specialists. Covers on the
machine which sometimes have to be removed and replaced for checks and adjustment
work are not mentioned here. The screws and nuts in brackets () are attachments of
machine parts which are to be loosened before making the adjustment and tightened again
after the adjustment has been carried out.
