Safety instructions 4
Keep electrical equipment out of reach of children
Children are not aware of the dangers posed by electrical equipment.
Never allow children to use the sewing machine unsupervised. Remember that
needles can also cause injury even when the machine has been turned off.
Keep the packaging out of the reach of children. There is a risk of suffocation.
Mains cable and mains connection
• Only connect the appliance to a power socket (230 V ~ 50 Hz) that is easy to
reach and is close to the place where you have set up the appliance.
• The power socket must be freely accessible so that you can unplug the
appliance quickly, if necessary.
• When you unplug the appliance, always take hold of the plug itself, not the
cable.
Fully unwind the cable during operation of the appliance.
• The mains cable and extension cable must be positioned so that no one can
trip over them.
• Never expose the cable to hot surfaces.
• When you perform the following activities, switch off and unplug the sewing
machine: Threading, changing the needle, setting the sewing foot, replacing
the light bulb, cleaning and maintenance work, when you have finished
sewing, and if your work is interrupted.
Never undertake your own repairs
• If the plug, cable or appliance is damaged, pull the mains plug immediately.
• If the sewing machine or mains cable has visible damage, the appliance must
not be used, in order to avoid risks.
Warning
Never try to open and/or repair the appliance yourself. There is a
risk of electric shock! If there is a fault contact our Service Centre
or other suitable specialist workshop.

holding screw.
• Do not use bent or blunt needles.
• When sewing, do not hold the fabric tight or pull the fabric. The needles could
break.
• When you have finished sewing, always move the needle to its highest
position.
Cleaning and storage
