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 specific 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.
