Members Teslabolt Posted January 21, 2020 Members Report Posted January 21, 2020 What would cause my presser foot to stay in the up position after using the knee lift or the hand lever? I can release it if I press very hard on the top of the foot. Consew 206RB-1 Thanks! Quote Sewing Machines: Consew 206RB-1

Members Pintodeluxe Posted January 22, 2020 Members Report Posted January 22, 2020 Might need a few drops of oil from above. Sometimes machines do this temporarily, if they've been sitting unused for too long. Other times you have a bent part. More times than not, a liberal oiling will free it up. One quick test to rule out the feet as a potential source... Remove the feet and re-test the lifting action. If the problem remains, it's the articulations in the head at fault. Quote
Moderator Wizcrafts Posted January 22, 2020 Moderator Report Posted January 22, 2020 An out of round hole in the pressure adjuster screw will cause the foot bar to hang until you rotate it to the right position. Also, add more pressure to overcome the out of round condition.

Members Gregg From Keystone Sewing Posted January 22, 2020 Members Report Posted January 22, 2020 See attached, it's likely the knee stopper highlighted index 2 is making contact before the knee lifter mechanism on the machine is. Also, the thrusting bar as they call it may be hitting and stopping at the bell crank, making it more like you are lifting the machine out of the stand rather than continuing to lift the bell crank up under the machine.

It still sticks after removing the feet. Can you be more specific on the articulations in the head being at fault? 11 hours ago, Wizcrafts said: An out of round hole in the pressure adjuster screw will cause the foot bar to hang until you rotate it to the right position.

I checked that as well and it is good. I can recreate the issue if I push down on the lift bar at the back that is connected to the lever underneath where the knee lift operates. How far is the presser foot designed to be moved up? Wondering if I am lifting too far? As I go up it becomes tighter and tighter. I will post a video of where it's hanging. Possibe the bar is bent? Man, I hope not. Quote Sewing Machines: Consew 206RB-1

Moderator Wizcrafts Posted January 22, 2020 Moderator Report Posted January 22, 2020 If rotating the adjuster screw doesn't free the presser bar, open the faceplate cover and observe the bar as you raise and attempt to lower it. You'll probably see where it is hanging up and be able to adjust or oil that part to free it.

If I tighten the presser bar spring (flat) all the way down, it does come free, but then I have will have terrible marks in my leather. I have the front faceplate off and cannot tell where it is getting hung up. I definitely feel some rubbing as I get to the top. Quote Sewing Machines: Consew 206RB-1
