I have a brother KH 881 and a KR 850 ribber, everytime i set it up the ribber bed falls off leaving the setting plates and brackets left in the main bed, it appears the brackets are not holding properly. I am not sure how to fix this frustrating problem.
The brackets fit on to a peg with an oval shaped fitting. To fit them correctly you have to lay the ribber upside down on a flat surface.Turn each bracket through 90 degrees towards the outside of the machine, fit them over the pegs so that the oval piece comes through the groove and turn them down into the correct position. Hope this helps.
