sewing machine settings

Hello, does anyone have instructions on how to adjust the back of the machine? It's a Pfaff 335 clone. It's hard to lift the presser foot.

Hi Romana,

What material are you sewing? Does the machine make good stitches?

Presser Foot Pressure

On my machines I typically reduce the force of the presser foot because it's uncomfortable to lift the presser foot otherwise. But I'm stitching lightweight materials predominantly. @Wizcrafts is often reminding us that the presser foot must not lift off the table when the thread take up lever tugs on the top thread to complete the stitch.

In some cases (stitching on corrugated plastic signs when i do not want to crush the signs) I remove the main pressure spring altogether. But for thinner material I have to put the spring back in or the feet don't contact the cylinder bed well enough.

Lubrication

In the case of the Pfaff 545, I needed to add a healthy dose of grease to the plates on the back of the machine where the knee lift connects---otherwise it was noisy and hard to move the knee lift.

Comfort Grips

Also in the case of the Pfaff 545, the hand lever for lifting the presser feet is so tiny and awkward that I wrapped some foam around it and held it in place with duct tape. This made it somewhat more comfortable to lift by hand. (The knee lift was much better after greasing)

Thank you, I'm currently taking the whole machine apart, cleaning it and putting it back together 😂
