You may find this at www.diplodocs.com or www.scribed.com free, otherwise you will probably need to buy it from www.sewingpartsonline.com or www.sewing-machine-manuals.com , I think it came as 2 books, Instruction Manual and Sewing Guide.

For basic overlock stitch, usually the tensions are all set at the midway point, although there is usually some tweaking for any particular machine. ...

Can be a variety of reasons. Firstly, is it a Quality thread? Cheap thread can be inconsistent in strength and also creates more 'dust'. Secondly, check the thread path for the top thread and also the bobbin thread. Reset tensions. Third, have you broken a needle lately - may have created a small burr on the bobbin / shuttle. Fourth, change the needle - is it the correct type and size for what you are sewing? Hope that helps!

Serger tension adjustment: reduce all dials to zero. Beginning with left needle, increase tension until an even stitch forms. Continue with right needle, then lower looper, and upper looper. If you are not able to adjust, take it to an experienced tech.

Check to see if feed dogs are engaged.

Looks like only the straight stitch and triple straight stitch can be decentered to the left by using the switch width slide.

Grasp the outside of the Flywheel really firmly and then using a piece of that rubber mat grip, grasp the inner wheel and turn it towards you. Sometimes if the machine hasn't been used for some time, the flywheel will get quite tight and you may need to apply some force. Is your machine the Blue top Star Series SU? Great strong workhorse machine. If you are a bit mechanical and what to delve into the machine, I'd suggest you find the Yahoo Group called Elna Heirlooms where owners of these Swiss made beauties share their passion and knowledge of these machines.

Not sure if you have a Star Series SU or the newer Air Electronic SU machines but its similar for both. Firstly unplug the machine from the power. On the top of the machine head above the light and presser foot, there is a little hole, place the tiny screw driver that came with your accessory kit into this hole and push down. The bulb and assembly will come down on a spring, you may need a spare hand from someone to push this down. The bulb is a bayonet socket, so push and turn bulb to release. It goes in on an angle though, sometimes its easier first time to lie machine over on a towel on its side and have a look at what you are doing as you push down on the socket. Bulbs are 15w bayonet, if you remove the old one and take it to the shop, should be able to find something similar even if its not branded Elna. Hope this assists.
