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
