本维修指导书按照相应的次序来说明该缝纫机的调整方法。请注意在结合
处各种位置设定都是相互关联的，所以绝对有必要按照描述的顺序来进行
调整。
对与形成线迹有关的零件安装调整时，要装一根无损坏的新机针。
在检查和调整操作中，机器罩壳拆下和重新装上的内容在本文中未提及。
请注意：
Caution: Risk of injury !
In case of repair, alteration or maintenance work turn off the main
switch and make sure to protect the machine from powering up
accidentally.
Carry out adjusting operations and functional tests of the running
machine only under observation of all safety measures and with
utmost caution.
The present service instruction describes the adjustment of the sewing
machine in an appropriate sequence. Please observe in this
connection that various setting positions are interdependent. Therefore
it is absolutely necessary to perform the adjustment following the
described order.
For all setting operations of parts involved in the stitch formation use a
new needle without any damage.
Machine covers having to be screwed off and on again for checking
and adjusting operations are not mentioned in the text.
281缝纫机的上轴上有扁榫， 这使调整相当便利。
万一需要调整，按转动方向上的第一排螺钉支住扁榫。
Please note:
The shaft of the special sewing machine 281 is provided with flat spots.
This facilitates the adjustment considerably.
In case of adjustments on flat spots the first screw in rotation direction
is put on such a flat spot.
