1. BASIC INFORMATION
Sewing machine S-311 is determined to sew buttonholes for outwears. Buttonholes type are listed on page
no. 1-6. The sewing machine S-311 is designed and produced to be simple for operation and very reliable.
Important design goals have been made to provide a safe machine that is simple and inexpensive to
maintain.
Sewing machine S-311 has four basic models: AF, CT, LTT and RDE. Each model can be combined
with ACL, except the model RDE.
Special electronic and mechanical safety devices protect the operator and the machine. There is a
special power lock out switch that permits the machine to be locked in the off position, so that it
cannot be cycled accidentally. There is a low air pressure detector that will not permit machine
operation if air pressure is dangerously low.
There are safety-warning labels on the machine in all areas that require special care. These must not
be removed. If they are lost replace them immediately.
You are the most important safety equipment of all. Be sure you understand the proper operation of
the machine. Never remove safety mechanisms or labels. We have made every effort to provide the
safest possible machine, but without complete knowledge of how this machine operates, and the use
of proper care by the operator, this machine can cause serious injury or death. That is why there are
safety warnings throughout these instructions that carry one of these messages.
Machine types are listed in the table on the manual page no. 1-4, 1-5.
DANGER! Possible loss of life.
WARNING! Possible serious injury or machine damage.
NOTICE! Possible injury or machine damage.
We recommend that service workers from AMF Reece oversee the installation and initial training of your

The most effective safety precaution is a well-managed safety program. Be sure those who use this
