Gauges And Service - Husqvarna 1200 Service Manual

Setting gauges
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 service tools is chiefly
intended as an indication as to how service men or service
workshops should be equipped.
The needle is often used as a setting gauge. The setting ratings
are adapted to needle size 90 and when setting in the feed direction,
the needle should be set in the middle of the needle hole. (Page.29).
