PREFACE
This Engineer's Manual is written for the 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 Manual intended for the maintenance personnel and
sewing operators at a sewing factory.
All personnel engaged in repair of ACF-164-1903 are required to carefully read Section 2 "Standard Adjustment"
which contains important information on the maintenance of ACF-164-1903.
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 latter 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 "ACF-164-1903 Parts Book" together with this Engineer's Manual.
