This may damage the special needle bar coating.
13.01 Notes on adjustment
All adjustments in this manual are based on a fully assembled machine and may only be
carried out by technical 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 that have to be completely adjusted. Both the preceding and following chapters
must be observed if only specific individual work steps are carried out.
The screws and nuts indicated in brackets ( ) are fastenings for machine parts, which must
be loosened before any adjustment and tightened again afterwards.
Unless otherwise stated, the machine must be disconnected from the electric
and pneumatic supplies for all adjustment work!
Risk of injury due to accidental machine start-up!
