that is a PDF of the owners manual you can click it and pull it up in browser and bookmark it. OR you can DL it (right click save link as yada yada) and keep it for always.
Sorry I dont know the answer if I did I would tell you but this should point you in the right direction at least. also if you go to this link here :

you can scroll down the page and DL the workshop manuals in PDF.
I hope this helps and you can sort it out.
