Back To The Top
To adjust timing on Consew 206RB style machines Rotary Hook screws need to released, the Rotary Hook aligned with the needle and then secured back on it's shaft. This is also a good time to check the condition of the sharp point of the rotary hook, if it is not perfectly rounded (bent), have a rough to touch surface or it's point is significantly dull - it is a time to get a new Rotary Hook.

1. Slide away Bobbin Cover Plate and remove Needle Plate by removing 2 screws on it's top.
2. Tilt the machine head back to open access to the bottom of the machine. Remove bottom bobbin from Rotary Hook. Check if Rotary Hook sharp point is in good condition - rotate Fly Wheel until the Rotary Hook sharp point is exposed - see pic, inspect it's condition. If it is damaged, order a new Rotary Hook before adjusting timing.
3. Release 2 screws, that secure the Rotary Hook on it's shaft, do not remove them. Release one screw, then rotate the Fly Wheel to expose and release the second screw.
4. Lower the needle to it's lowest position by rotating the Fly Wheel
5. Rotate the Rotary Hook by hand until it's sharp point will be against the needle, touching it with it's flat sharpened part on the sharp point. While holding the Rotary hook in this position slightly rotate the Fly Wheel to slightly move the needle up, until the sharp point of the Rotary Hook will be in the middle of the needle cut out - see picture.
6. Holding the Rotary Hook at above position with the sharp point touching the needle slightly move the Rotary Hook away from the needle along it's shaft, to create a minimal distance between the needle and the Rotary hook - Do Not rotate the hook on it's shaft while doing it.
7. While carefully holding the Rotary hook in this position tighten back it's screws, that secure it on it's shaft, the ones, that were released at the beginning of this alignment. Tighten one screw first, let go your hand of the Rotary Hook and then rotate the Fly Wheel to expose and tighten the second screw.
8. The alignment is complete. Tilt back the machine head and install back the 2 cover plates that were removed at the beginning of alignment.

Consew 206RB-5 foot pushing back material issue fix - adjustment
Back To The Top
When you experience an issue with material being pushed back before it is fed forward by the walking foot the walking motion of your machine may need adjustment.
This issue is caused by walking foot landing too early, as it is still travels forward to it's front most position. To fix this problem - lower the presser foot and then lower the walking foot by spinning the wheel until it is as close to the front as it gets. Now slightly release the screw shown on the picture and tighten it back. It will adjust the timing of the walking foot reaching the front and landing simultaneously. Problem solved.
