Neddle brakes - Out off the course when sewing large patterns
The reason of this missbehave is a destroyed plastic buffer, which is attached to the move limiter for the needle bar frame. It is quite a little delicate to open the machine's housing due to some hidden scews. Neccesary is to open it. You have to empty the accesory drawer. Then you have to remove the underside cover. The right side cover must be removed as well (take care of the screw which fixes the middle part of this. It is found from below through a small channel, just fitting a screw driver through the hole). Below the movable small table at the lower left front, there is a small turnknob for adjusting the horizontal alignment of big patterns. This knob has to be pulled out, also the round cover below it (best use a little hook and pull the cover out at its small hole seen from below). Remove the two screws directly under the movable table. Remove all screws, which are fixing the front cover from below the machine. Remove the hood which covers the needle bar just as you would like to change the light bulb). There are two scews to be removed holding the front cover. The foot presser handle has to be removed as well. Now gently pull the front cover off the machine. It might be neccesary to help moving the cover at the upper side, inserting a screw drivers blade into the gap between cover and machine frame. The cover should snap off now, if there are no forgotten screw connections left.
After the cover is released, take care of the ribbon cable, wich connects the display etc. with the electronich mainboard. the ribbon cable can be teared out carefully of the mainboard connector. Now you have clear sight onto the needle bar's mechanics. if you push the needle bar to the right, you can see, that the needle bar frame is stopped from a small metal piece, fixed with two screws. At the touch point of the frame and the metal piece, there is (or was) the plastic buffer, which is now destroyed and has the consistence of used chewing gum.
There are two choices: Either you find a spare part metal piece with good plastic buffer or you will have to improvise the buffer by handcrafting it.
After you repaired the metal piece, you will have to adjust it.
Moving the needle bar to the right, the needle bar clutch have to release the needle bar before the needle is over the point to stitch to the plate.
Remark: Due to the different length of the screws it might be a good idea to give some notes, which length belong to which hole.
Wish a good success,
