Questions about my new Pfaff 1245

[dikman]

Yet another way of doing it, nice one Brtz.

[Northmount]

Item 1

You should reverse after the needle has risen about 1/4" from bottom of its stroke.  Stop before you reverse so you have control.  If you reverse too early, the hook won't have caught the loop and you have a missed stitch.

When starting a line of stitching, you can start in reverse about 3 stitches before the beginning end of the stitch line, then switch to forward.  Same rule as above applies.

Item 2

By hand-wheeling and adjusting the reverse leaver/stitch length to hit the target.

Item 3

When starting a stitch line, hold both tails to keep tension on them for the first few stitches.  When doing your top stitching, don't pull the seam too tight.  When reversing, don't lift the presser foot.  You might need more top and bottom tension.

Item 4 - belt dust

Could be rough spot on a pulley, or misaligned.  Possibly over tightened might do it too.  Should be able to depress the belt about an inch by pressing with your thumb midway between pulleys without having to exert a lot of pressure.  There is not a heavy load on these belts, so doesn't need to be really tight.  Do you have a belt riding high above the rim of one of the pulleys?

Tom,

Thanks a lot for explanations!

#1 - I did practice but need to work on it. Not always getting through the same hole result.

#2 - Didn't practice yet, but I didn't realize that reverese lever can be used for that, all videos I've seen involved pressure release and material movement.

#3 - I will practice more. Yesterday I tried to increase tension on both top/bottom and started to get a lot of tangles on a bottom. Took me awhile to figure out. What happened was that top thread got out of tensioner and was on a tensioner spool but not between plates. And even with releaved pressure it wasn't getting in. Good expirience I guess!

#4 - See picture. I think it makes less dust now. It is straight, it does deflect about 1 inch. Completely inside pulley on bottom pulley, top pulley see pic, about even.

Belt is at the correct depth on the top pulley.  Bottom pulley belt should not ride in the bottom of the groove.  Is that bracket or guard just to the right of the belt rubbing on the belt?
