First of all, thank you very much for choosing FIXYA today for your online technical support needs.
Here is a link to the Mitsubishi Sewing Machines Support website which has links to the instruction manuals for all their products:http://www.mitsubishi-sewing-machines.com/products/lockstitch-machines/
I was unable to locate the exact model number you quoted, but the LS2-1130-BOB / MOB / HOB models were the closest listed.
To see the instruction manuals for these machines, just click on the link, which is the underlined and blue highlighted text just above.
When you get to the SUPPORT WEBSITE, just click on the exact model number which most closely matches your machine.
Then look on the right hand side of the next page and click on the INSTRUCTION MANUAL icon.
When it asks you if you want to open or save the document, select OPEN.
This will open a new web browser page automatically for you and allow you to view the information at the website indicated and the contents of the Owner's Manual.
