How do I change the needle ?
- Only use recommended home sewing machine needles. Use of any other needle may bend the needle or damage the machine.
- Never use bent needles. Bent needles can easily break, possibly resulting in injuries.
Checking the needle
-
The sewing needle must always be straight and sharp for smooth sewing.
-
Put the flat side of the needle on a flat surface. Check the needle from the top and the sides. Dispose of any bent needles safely.
(1) Parallel space
(2) Level surface (bobbin cover, glass, etc.)
Replacing the needle

Turn off the machine.
Always turn off the machine before you change the needle. Otherwise, injuries may occur if the foot controller is accidentally pressed and the machine starts sewing.
-
Raise the needle by turning the handwheel toward you (counterclockwise) so that the mark on the wheel points up.
