Bonis A18 skipping stitches

[JazzVinz]

Hello !

I just bought a Bonis A18. My grandfather was a furrier and I watched him a lot while working when I was a kid.

While trying the machine, I saw it was skipping some stitches. When doing manual the 1st stitches were good and then only 1 / 2 or 3, and none with the electrical motor.

I tried to change the thread but didn't change anything except I broke the needle (292 serie). I think my threading is good.

I have found a way to buy new needles (bought 3 different sizes 16, 18 & 20, but doesn't know what size to chose...).

I would like to know what can I do to fix the stitiching problem, if anybody as an idea

Can we see a video of the skipping?

Your needle isn’t set correctly, or even the wrong needle is installed.

Like Gary said you might have to not set your needle so deep.Here's a manual.
