Notes on adjustment

.01
All adjustments in this manual are based on a fully assembled machine and may only be car-
ried out by technical staff trained for this purpose. Machine covers, which have to be re-
moved 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 ma-
chines that have to be completely adjusted. Both the preceding and following chapters must
be observed if only specifi c individual work steps are carried out. Screws and nuts indicated
in brackets ( ) are fastenings for machine parts, which must be loosened before any adjust-
ment and tightened again afterwards.
