Changing the needle
CAUTION:
Always make sure to turn the power switch off and
disconnect the machine from power supply before
changing the needle.
Raise the needle by turning the handwheel toward you
and lower the presser foot.
Switch off the power switch.
Loosen the needle clamp screw by turning it coun-
terclockwise.
Remove the needle from the clamp.
Insert a new needle into the needle clamp with the
flat side of the needle to the rear.
When inserting the needle into the needle clamp,
push it up against the stopper pin and tighten the
needle clamp screw firmly.
• To check the needle:
To check needle straightness, place the flat side of the
needle onto something flat (a stitch plate, glass etc.) The
gap between the needle and the flat surface should be
consistent.
Never use a blunt needle.
Fabric and Needle Chart
• Use a needle size of 11/75 or 14/90 for general
sewing work.
• A fine thread and a fine needle must be used to
sew lightweight fabric to prevent damage to the
fabric.
• Heavy fabric requires a needle large enough to
pierce the fabric without the needle thread fraying.
• Always test the needle size on a spare section of
the fabric you will be using for sewing.
• In general, use the same thread for the needle
and the bobbin.
