Notes on adjustment

.01
All following adjustments are based on a fully assembled machine and may only be carried
out by expert staff trained for this purpose.
Machine covers, which have to be removed and replaced to carry out checks and
adjustments, are not mentioned in the text.
The order of the following chapters corresponds to the most logical work sequence for
machines which have to be completely adjusted. If only specific individual work steps are
carried out, both the preceding and following chapters must be observed.
Screws, nuts indicated in brackets ( ) are fastenings for machine parts, which must be
loosened before adjustment and tightened again afterwards.
