Kobe knee lifter too hard to push

[pattysoup]

Hi all 

New to all of this fun.

I have a new clone 341 Kobe? Problem - knee lift too tight

- when using the knee lift the black bar connected to the knee lift is extremely difficult to move. (scratching paint off the machine) and the bolt connecting the knee lift pad spins. 

questions:  1. Can I fix this?  I do not like the knee lift and would like an alternative to using it. Any suggestions.

I think you have the lever under the table on the knee lever in to far. You need it out as far as it will go to give you the leverage to move the lifter.

You can replace the knee lever with a foot pedal that bolts onto the pedal bar and uses a chain to connect to a clip on the end of the black lifting bar.

Or connect the chain to the wire loop that hooks onto the knee lift (although hooking onto the hole at the end of the lifting bar will give greater leverage for lifting).

Thank you for getting back to me.

Purchased the machine from Chris at Japan Sewing Machines. I did ask him for a speed reducer but he said I did not need one and he does not have any to sell. So now what? I found an engineering manual for the1341 on this platform but not the 341 which I believe this machine to be.

I used this platform to do my research before purchasing from Chris - I knew enough to be a danger to myself. I came close to purchasing the Techsew 2750 again all information found here  

Thank you Bert and Wiz - will give it a try. Wiz the pedal bar and chain will be my next purchase. Does anyone know where a Canadian could purchase such a thing?

Kind regards

The label on the machine says LS-1341. The geometry on that knee lifter looks wrong, normally you push sideways with your knee to operate it but yours looks like you have to push up with the knee?

Sadly I cannot draw a straight line, but try this before you go doing else.

Loosen the adjusting nut and move the small lever in red forward, roughly as drawn, then you should be able to lift the foot easier.

Hi Patty

In the future, please start a new thread when your topic is different than the OP's topic.

I agree with Bert51. I would also add a couple of things. Have you called the dealer for some advise? I would remove the connecting cable and back off the tension return spring from the level to see if the pivoting bolt for the level is to tight / sticky and or the lever spring maybe also set to high giving more resistance then necessary. I may even try connecting the cable out to the last hole if possible to get as much leverage you can on the lift lever. The knee pad on the lifting mechanism needs to be move so the pad would be at a 7 o'clock position as a starting point. Bolts need to be really tight and bite into the round shaft or a flat spot ground into the shaft to prevent slippage.

Hi all

Thank you, Tom I will pay more attention to future post location. I just completed the fix and used a combo of all guidance. Pics attached. Enlarged hole and moved wire connection.

 Thank you.
