If this is a follow up question regarding replacing the spool pin, I don't think you HAVE to take the cover off to replace it. However, as a general rule, on Singer machines, the back cover must be removed first, and I have a feeling you tried to remove the front cover. Most repairs can be made from the back anyway.

If you really want to know, call or email Sewing Parts Online; they carry service manuals, and although they don't have yours in stock, they are always happy to order it for you, and a nominal fee.

You probably need to open the left cover first, then look for a latch or something to release the top.

How do I remove the top on a Bernina 807 in order to chnage th elong belt ?

V-Belt replacement 801/801 Up Machines

Only the belt cover needs to be removed for this belt change. This is done by removing the three screws on the end/belt cover. Loosen the 5mm Allen socket head screw below the step pulley to relieve the belt tension. Remove the lower motor belt. Lift the step pulley and slide off the hand-wheel, (assuming that you have already removed the release knob and clutch ring).

Additional top cover removals 807/801 Minimatic machines

Early 807 machines had two expansion nipples in the top cover that fit into receptor holes in the upper arm frame. Simply pull up the top cover.

Very late models may have a push button latch mechanism, same as on the 801 machines except those fitted with carrying handles, i.e. 801 Sport, 810 machines.

This is accessed by opening the light cover and finding an aluminum knob in the upper left hand corner of the upper arm frame. Push this in and the cover will release. Lift off the top cover.

How to remove a sewing machine cover?

Most machines have some sort of clip or clamp near the bottom to release the cover, if it is the carrying case you're trying to remove. If you are trying to open the machine to see the motor and moving parts, many of them simply pop open at the side or top, or you may need to remove some screws. The model name would help.

Pfaff Creative 1475 CD Hi. Something is loose or broke inside the machine at the top right. I can see inside where the bobbin is pre-wound and the manual wheel that things are loos. How do I go about...

Quite easy - open the top cover. There are two screws - one in front of where the thread spool sits, the other up near the right hand end. Undo them and the top cover will come off.

The cam seems to be locked up and won't release. I have the settings where the manual says to, but the button does not go down to release the cam.

Is this a Supermatic (green), Star SU (white with blue top) or an Air Electronic SU model, I'm guessing that it is one of these Elna models?
If it is one of the two latter models, then you need to set the stitch width to zero, stitch length to zero to disengage the feeler arms that read off the disc. Then press on the cam release knob in the middle of the Elnagraph.

The earlier Supermatics were a bit different and there was a tool you used to remove the cams I think.

You could try to remove to the top cover and then see if you can get some oil in under the Elnagraph, this may help to free up the mechanisim. There is a little finger that goes into the cam from the underside and you don't want to damage this as you remove the cam.

My other suggestion is to join the "Elna Heirlooms" user group on and see if one of the members there has a suggestion on how to get the cam off. There are some really knowledgeable Elna owners there so one of them may have encountered this problem too.

Bobbin cover door is stuck on Bernina 930 Electronic, and won't open. Can you help me?

Tricky !!! I dont know why the door is stuck, but its possible that the spring-loaded plunger in the top of the bobbin door is stuck into the cover of the free-arm. If there is suficient gap between the top of the bobbin door and the free-arm cover, you could try sliding a thin piece of metal or a very small flat-bladed screwdriver between the two, in the dead-centre of the bobbin door - that's where the plunger is located. By gently manouvreing the screwdriver in, you might be able to release it - be careful, because it's possible that the retaining circlip has dropped-off the bottom, in which case, the plunger and its pressure spring might fly out when the bobbin door opens. If that doesn't work, you could try unscrewing and removing the stitch plate and, again, with a small flat-bladed screwdriver, see if you can release the free-arm cover catch that's next to the top-left-hand-side of the bobbin door, but that's a very risky approach, because the feed-dogs will be in the way and you dont want to mangle any of the hook/shuttle parts etc. You need to find out why the bobbin door is not seated properly - it may be that the bottom hinge that also carries the hook/shuttle retainer has come out of the left-hand hinge mount in the free-arm. Good Luck.

How do you take the top off of a Bernina 817 sewing machine

Open the face plate (the hinged door where the light bulb lives). Near the top and back, near the upper hinge, is a round, grooved button. Push the button and the top cover is released. It's in the manual, but the picture isn't clear, or something has changed. You can get a free manual by searching for bernina 817 manual pdf.

Thread wound around disc of take-up lever on bernina 1008

Hi, there is no top cover on this machine. First the side cover has to come off then the back cover. Under the back cover there is a rigidity plate with many screws that has to come off and then you might be able to get at the take up lever mechanism. I'm not saying you can't do this but it might just be the time to have a tech go in and service this machine completely.
The thread must have slipped out of the end of the takeup lever and wound in the mechanism. It happens.
If you feel you want to do this yourself feel free to contact me and I can walk you through getting the covers off.
Possibly you can get a tweezers or needlenose pliers in through the front slot, grasp the thread and turn the handwheel bit by bit and see if it will unwind as you pull it out.
