Handle the appliance with care
− The sewing machine has suction feet for stability. Nevertheless,
ensure that the machine is placed on a stable, level work
surface and that all four feet are touching the work surface.
− When the appliance is in use, the air vents must remain free: do
not allow any foreign objects (e.g. dust, pieces of thread etc.) to
get into the openings.
− Never place anything onto the foot pedal.
− Use only the supplied accessories. Needles are available from
specialist retailers.
− Only use specialist sewing machine oil to lubricate the

the net from above over the spool.
− Pull the net over the spool up to the end and
turn up the excess part.
If the yarn has already been threaded,
the thread spool can be removed from
the yarn needle and the net pulled up
over the spool from below.
