...

go google and type in-- operators manual for janome 2008 sewing machine --- down load a site that has a pdf version and it will have all the information that you will need

The manufacturers web sites often have detailed threading diagrams to view, try there. If not email them for help. Janome are usually helpful

sewusa.com has some threading diagrams

The detail for threading could not be more clear...there is a diagram on the inside door...ensure thread is pulled tight in tension units.

I would really suggest that you start with this website www.sewing.about.com, there is so much really good general information on sewing, sewing machines, threading up, trouble shooting, using the right sized needle and quality thread and it is all free.

I have found a pdf file of the manual on line ftp://ftp.drivehq.com/ click on the link saying "RX18S instructions", it will take a while to load as its 17MB.

Try changing the needle sometimes over use causes burrs on the end of a needle and always remember to use proper needles to appropriate fabrics. Change needles frequently to avoid unnecessary wear on the feed dog teeth

If it was sewing correctly BEFORE the needle break...why did the needle break in the first place?...and what fixes did you make?
If it sewed properly...what changed?

Cut your upper thread close to the spool...make sure the presser foot is raised and pull the cut off thread section through/out of the machine from the needle area (sewing direction...do not pull the thread backwards!)

Clean out the bobbin area...remove any traces of lint or pieces of thread...look for any broken off needle pieces... brush the bobbin area out....then add a drop of sewing machine oil (but only if your manual says to oil that area).

Remove the needle plate to expose the feed dogs...brush/clean out that area too and add a drop of sewing machine oil...then secure the needle plate back on.
Replace the needle...do it again...yup...some needles arrive bad from the factory. Make sure the needle is inserted and positioned properly. Then thread the machine WITH the presser foot in raised position. (The thread needs to get seated into the upper tensions.)
..with the.presser foot down...thread the new needle.
Oh...and use the correct needle for the thread. (a universal 80/12 is standard).
Thread can cause issues too. Try a different bobbin, or maybe a different spool of thread to see if that makes a difference.

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!
