Nick-O Sew NKS-441 Series, Engineer'S Manual, Page: 3 / 34

This Engineer’s Manual is written for technical personnel who are responsible for the service and maintenance of
the sewing machine.. This manual describes “Adjustment Procedure”, “Results of Improper Adjustment”, and other
functions which are not covered by the Instruction Book intended for the maintenance personnel and sewing operators
at a sewing factory.
All personnel engaged in repair of NKS-441 are required to carefully read Section 2 “Standard Adjustment” which
contains important information on the maintenance of NKS-441.
The “Standard Adjustment” consists of two parts: the former part presents illustration and simplified explanation for
the convenience of reconfirmation of the required adjustment values in carrying out actual adjustment after reading
this manual once; and the other part provides “Results of Improper Adjustment” in which sewing and/or mechanical
failures, and the correcting procedures are explained for those persons who perform such adjustment for the first
time. It is advisable to use “NKS-441 Parts Book” together with this Engineer’s Manual.
