How to check the needle
Sewing with a bent needle is extremely dangerous since the needle may break while the machine is being operated.
Before using the needle, place the flat side of the needle on a flat surface and check that the distance between the needle and the flat surface is even.
If the distance between the needle and the flat surface is not even, the needle is bent.
Do not use a bent needle.
