PREFACE

This Service Manual is intended for use by service personnel and details the specifications,

construction, theory of operation, and maintenance for the Brother machines noted on the front

cover. It includes information required for troubleshooting and service--disassembly, reassembly,

equipment in a timely manner and order spare parts as necessary.

To perform appropriate maintenance so that the machine is always in the best possible condition

for the customer, service personnel must adequately understand and apply this manual.
