Service Tools - Husqvarna VIKING 350 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 thosemost 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 service tools is
