5.  Safety instructions

Like any other electrical device, a sewing
machine can cause serious, even life-threatening
injuries. To avoid this, and in order to work

safely:

• Before initial use of your sewing machine,
read these operating instructions thoroughly.

• Keep the operating instructions in a suitable
place near the machine. When passing the
appliance on to others, always enclose the
operating instructions.

• Always disconnect the power supply when
leaving the machine unattended. This will

prevent the risk of accidents if the machine
is switched on accidentally.

• First pull the power plug before changing
the bulb or performing maintenance work
on the machine.

This will prevent possibly life-threatening
electric shocks.

• Do not remove the plug from the socket by

pulling on the cable. Always grip the plug
and not the cable when pulling out the
power plug.

• Only use the sewing machine in dry rooms.

• In case of any visible damage on the machine,
the foot switch or the power cable: Have the

damage repaired by Customer Service before
using the sewing machine again.

• Never let children or elderly persons handle
the machine unsupervised because they may
not properly appreciate the possible dangers.
Keep electrical appliances outside the reach
of children.

• Never use the machine when the ventilation
apertures are blocked. Keep the ventilation
apertures of the machine and the foot switch
free from fluff, dust and waste material.

 Warning

against injuries and material damages:

According to legislation, you as the user of
an electrical appliance are responsible for
preventing possible accidents through safety­conscious behaviour:

• Keep your work space tidy. An untidy

workplace can lead to accidents.

• Provide adequate lighting when working!

• Do not wear loose clothing or jewellery,
as these can be caught in the moving parts.
You should also wear a hair net if you have
long hair.

• Avoid abnormal posture. Remain steady
and in a well-balanced position at all times.

• Be alert! Pay attention to what you are doing.
Always take a rational approach to your work.
Never work with the sewing machine if you
are unable to concentrate or if you are feeling
unwell!

If accidents occur as a result of handling the
machine with insufficient care, or failure to
follow the safety instructions in this manual,
then the manufacturer cannot accept liability.
