CAUTION

Always make sure to turn the power switch off and disconnect the machine from power supply before changing the needle.

zTurn off the power switch.

Raise the needle to its highest position by turning the handwheel counterclockwise, and lowering the presser foot. Loosen the needle clamp screw q by turning it counterclockwise. Remove the needle from the needle clamp w.

xInsert a new needle into the needle clamp w with the flat side to the rear. When inserting the needle into the needle clamp w, push it up as far as it goes. Tighten the needle clamp screw q firmly by turning it clockwise.

cTo see if the needle is good, place the flat side of the needle onto something flat (needle plate, glass, etc.). The gap between the needle and the flat surface should be consistent. Never use a bent or blunt needle.

A damaged needle can cause permanent snags or runs in knits, fine silks and silk-like fabrics.
