Members Romana Posted Wednesday at 04:38 PM Members Report Posted Wednesday at 04:38 PM 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. Quote
friquant Posted Wednesday at 05:29 PM Report Posted Wednesday at 05:29 PM (edited) 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) Edited Wednesday at 05:30 PM by friquant Quote friquant. Like a frequent, piquant flyer.

Tlak přítlačné patky Na svých strojích obvykle snižuji sílu přítlačné patky, protože jinak je nepohodlné ji zvedat. Ale šiju převážně lehké materiály.@Čarodějnictví nám často připomíná, že přítlačná patka se nesmí zvednout ze stolu, když páka navíječe nitě tahá za horní nit a dokončuje steh. V některých případech (šití na vlnité plastové cedule, když nechci cedule zmačkat) hlavní přítlačnou pružinu úplně odstraním. Ale u tenčího materiálu musím pružinu vrátit zpět, jinak se nožičky dostatečně nedotýkají lůžka válce. Mazání V případě Pfaff 545 jsem musel přidat pořádnou dávku maziva na destičky na zadní straně stroje, kde se připojuje kolenní zvedák – jinak byl hlučný a obtížně se s ním pohybovalo. Komfortní rukojeti Také v případě Pfaff 545 je ruční páka pro zvedání přítlačných patek tak malá a nepraktická, že jsem ji omotal molitanem a připevnil lepicí páskou. Díky tomu se zvedání rukou o něco pohodlněji provádí. (Zvedání kolenem bylo po promazání mnohem lepší.) I have already put the back of the machine back together, but after dropping the presser foot, the outer presser foot won't let go and stays hanging. I also discovered that there is a spring left in it and I don't know where it belongs. Quote
friquant Posted 9 hours ago Report Posted 9 hours ago (edited) That spring likely slides around either the outer presser foot bar or the inner presser foot bar. On my machine, these two bars are different diameters, so that will tell you which one it goes around. Looks too short to be the one that drops in the top for your pressure adjustment. By any chance do you have pictures from before and after? Perhaps someone with a 335 can post a picture to show where the springs belong. Edited 9 hours ago by friquant Quote friquant.
