Jump foot

[Guest Paul]

Hi there I have brought a singer 45k89 with the jump foot and the top keeps slipping has anybody got info on setting it up properly the 45k manual doesn’t even mention this part

I moved you over to Leather Sewing Machines, where you're more likely to get some help.

I'm going to suggest that you join the forum here so you'll be able to receive notifications about replies. 

I believe this machine has been talked about here quite a bit, so searching may uncover what you're looking for.

Post some pictures of your machine please. I had a flat bed version of the 45K with I think the same jump foot mechanism but that was some time ago.

I have jump feet on my Adler 4-4 and on my Adler 5-8 as well.

Picture 1 shows the screw around the top of the machine head to increase or lessen foot pressure.

Loosen the bottom slotted lock nut - adjust pressure as needed - tighten lock nut.

 

Picture 2 shows the screw to adjust "height of jump" = foot lift.

The more you screw in the bolt - the higher the lift.

Foot lift should be adjusted to a minimum = max. about 1/8"(3mm) above material at full lift.

 

If all fails - have the bottom of your foot bead blasted to obtain more traction.

Forgot to mention - the Adlers came with a little C hook spanner for the locking nut for the foot pressure.

The size is 25 to 28mm = 1" to 1 1/8" --- you can still buy them new from Ebay for example.

 

Many of the old bicycle flat "all in one tools" have such a concoction built in - maybe you have one kicking around your shed.

Here is one that looks like it may work for a Singer - if your 45K has this lock nut - the ones in the manual do not :

Also check your bottom feed dog.

Most have a long slot where it is attached to the drive mechanism to adjust lift - if the feed dog does not produce enough lift - it will not transport material properly.

Here just a pic :

Hans,

the jump foot mechanism on a 45K89 is different compared with the one from the Adler 4 or 5.

However at one time Singer had a similar one as Adler. With other words Singer had 2 different jump foot systems on the 45k line.

Okay - I´ll keep that stored in my memory bank.

But the screw to adjust foot pressure is in the same place - just don´t know if the Singer 45K89 had the lock nut.

When I was looking for bigger sewing machines - it was hard to find the 45K models with reverse - have yet to see one with jump foot AND reverse.

Also the Adler 4 and 5 here in Germany used to be quite moderately priced - I got both of mine for a very decent price each - even though for the 4-4 I had to drive nigh on 1200 klicks ( 750 miles ) there and return to pick it up. That amounted to a looong day of driving.
