Service Tools - Singer Inspiration 4228 Service Manual

Service tools

A reasonable requirement in a domestic sewing machine is that it should able to sew all types
of fabrics used in the home. The settings made when assembling and sewing-in the machines
are those most suited to give the best results in the majority of fabrics and fabric combinations.
In doing so, consideration has been given to the requirements of different markets. This does,
however, mean that when sewing extreme fabrics, better results may be obtained in certain
cases by altering the settings. It must be pointed out that these altered settings can cause
poorer results on more normal fabrics. How the different standard ratings are set can be seen
from the description under each setting instruction. The following list of setting gauges and ser-
vice tools is intended as an instruction about the special service tools needed to servicing this
