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. And this manual describes “Standard Adjustment”, “Adjustment
Procedures”, “Results of Improper Adjustment”, and other important information which are not covered by the
Instruction Manual.
It is advisable to use the relevant Instruction Manual and Parts List together with this Engineer’s Manual when
carrying out the maintenance of these machines.
In addition, for the motor for the sewing machine with thread trimmer, refer to the separate Instruction Manual
or Engineer’s Manual for the motor. And for the control panel, refer to the Instruction Manual for the control
panel.
This manual gives the “Standard Adjustment” on the former page under which the most basic adjustment value
is described, and on the latter page “Results of Improper Adjustment” under which stitching errors and troubles
arising from mechanical failures are described together with the “Adjustment Procedures”.
