PREFACE
This Engineer’s Manual is written for the technical personnel who are responsible for the service and maintenance
of the machine.
The Instruction Manual for these machines intended for the maintenance personnel and operators at an apparel
factory contains operating instructions in detail.
It is advisable to use the Instruction Manual and Parts List together with this Engineer's Manual when carrying out
the maintenance of these machines.
This manual gives the "StandardAdjustment" on the former section under which the most basic adjustment value
is described and on the latter section the "Results of Improper Adjustment" under which stitching errors and
troubles arising from mechanical failures and "How To Adjust" are described.
