Kobe 1541S alternating lift height adjustment

[plinkercases]

I have a new to me Kobe 1541S (made by same as JUKI contractor so clone or rebadge whatever...) and the pressure feet do not lift the same height when walking.

They do when lifted by knee or hand.

I can find no info on how to adjust the walking lift of just one of the feet.

The front or needle foot will only lift less than half the height of the rear foot when walking and this make it almost useless to me but I am sure can be changed somehow.

If it's the same as a Juki 1541 will these manuals help? http://www.danreetz.com/blog/2013/09/29/juki-dnu-1541s-service-manual-and-users-manual/

Sometimes it's necessary to adjust the position of the clamps on the bar that the outer presser foot is mounted to.

Great link to the manuals, I found these great. Thanks Dikmam

It’s sure helpful if one prints out the pages so to view one page and simultaneously is able to read the adjustment instruction on opposite page, as intended.  So to help this posted question pages 8-9 would be in a good view.  

Theres no doubt you should print the manual link, or save it then later try it. Its sometimes handy to check how its setup, so to print double side correctly for your layout viewing pages. 

Good day

ps: i started using them stickies for holes on the page the 3 ring binder uses.

Dikman thanks and yes I have these (but excellent link thanks) and suspect that while there isn't a specific fix fro the problem I have I can apply the lift height fix to the alternating walking lift issue. I think since this doesn't have the adjustment knob I need to look at this area....  I suspect the screw in the slot on the right but haven't had time to patiently fiddle with it.

Stay tuned.

It maybe benefit to check pages 12 & 13 in that manual, carefully.

I found it a best practice to look over each step in the manual, particularly as they many times work upon the other, so following an order seems to be correct, 

  Good day

A bit different to my machines (I suspect those slotted pieces are just guides? A bit hard to see with all those fluffy bits in there). Best thing is to study the motion/movement of the feet and look at the various linkages and clamps. Try adjusting one at a time to see what effect it has, that way you should be able to set them back to how they were. These things aren't rocket science (just clever mechanical contraptions) so what can be undone can be put back together - eventually.

As I thought as well. I am not afraid of mechanical things since as you say they can be put back together (by someone at least!).

More will be revealed.....

Heres a step from the link that can help. 

I think the picture is at top of page 12 in the manual linked, and corresponding to this copied text below. Pretty sure this works. It does and did on each of my 4 Jukis

Good luck on your mission  

 

(2) Alternate momentum

1. Set the stitch dial to “0”.
2. Turn the handwheel to make sure that the amount of alternate
vertical movement of walking foot 1 and presser foot 2 is
almost equal.
3. When the amount is not equal, loosen setscrew 3 in the top
feed rear arm and adjust so that the amount should be equal. Adjust the amount almost to A = B.
TM When the amount of alternate vertical movement of the walking foot is larger than that of the presser foot :
1) Loosen setscrew 3 in the top feed rear arm in the state that walking foot 1 is raised a little, press walking foot 1 to the feed dog.
2) Re-tighten the setscrew and turn the handwheel to make sure of the amount of the amount of alternate vertical movement of the walking foot and the presser foot.
Adjust the vertical stroke of the walking foot so that it is larger than that of the presser foot in accordance with the sewing products.
TM Sewing sponge material or the like
TM Sewing material with overlapped sections
When the alternative vertical strokes of the walking foot and presser foot are considerably different
TM The stitch pitch is different from the value set by the dial.
TM Decrease the number of revolution of the motor a little since the feed efficiency is decreased.

Thanks brmax.... I will apply what I can but this model doesn't have a dial on the top....

I understand, mine don't either. I sure wished, but in any case that specific adjustment for us both on standard styles will be pictured on top of page 10 and its written adj. procedure adjacent page. 

The adjustments now for the walk and presser foot ( equal ) are listed as mentioned pictured on page 12 of the Juki manual and written on the adjacent page.  

It does as you can notice have a separate designation photo for machines with automatic thread trimmer. Mine doesn't so the photo left is relevant to me. 

Many times reminding ourselves the stitch knob positioned correctly for these adjustments is critical. They many times require different settings for different steps in these adjustments. 

 

Have a good day
