ESD
ATTENTION!
It is of the utmost importance that precautions are being taken in order to avoid damage of the electronics
by electro static discharges ESD (=Electro Static Discharge). To avoid that these errors arise it is important
to handle loose circuit boards in a controlled way.
Electrostatic charges are caused by:
• When a person is walking (influence) over synthetic tilled or carpeted floor
• When its friction between and separation of two insulating materials.
If this static electricity discharges through electronic components, these may be partially or irreparably
damaged. Electrostatically charged persons represent the greatest danger for components. This can be dis-
sipated by controlled electrostatic discharge.
Always use wrist band when servicing.

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 fa-
brics,
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 intended as an instruction about the special service tools needed to servicing this machine.
1. On several different occasions the needle is used as a setting gauge.
The setting ratings are adapted to needle 90. Make sure to use an undamaged needle.
