What do you mean you are unable to pull the bobbin thread through, elaboration would help solve the problem...
I suspect I'm having the same problem with you if it's anything to do with the top thread looping around in the bobbin holder.

Damn machine!

Here's what the manual says:

Before sewing, fit the button-hold foot to the machine (long white plastic thing with red, ruler like markings).

Select the pattern selector dial that is solid green on the left hand side. Set the dial to "1" position. Sew the left side and raise the needle.

Select the pattern selector dial that is solid green on the top and bottom. Set the dial to "2" position. Sew 5-6 stitches and raise the needle.

Select the pattern selector dial that is solid green on the right hand side. Set the dial to "3" position. Sew the right side. Raise the needle.

Select the pattern selector dial that is solid green on the top and bottom. Set the dial to "4" position. Sew 5-6 stitches and raise the needle.

Hope that helps...

SOURCE: machine will not complete a buttonhole, keeps showing error code 6L. No error code listed in manual. Machine will only do first half of buttonhole and then shows code and stops.

I've been looking too and I found here http://sewing.patternreview.com/cgi-bin/sewingclasses/board.pl?t=18328that you need to put the bar behind the needle threader down. I think they call it a button hole stop? I don't know, but it worked. I didn't even know it existed. But it solved my problem. On my Kenmore it looks like a black lever and you pull it down. It tells the button-holer that you are at the end of the hole and it needs to backup. nifty, kind of.
