White Model 1455 manual?

I came into a White model 1455 machine of recent. I searched online 
where to buy a manual and only managed to get ripped of for $18 by 
SewingStyle.com - They do not send my manual nor answer my email or 
telephone messages but send me offers to buy more stuff now.
	Anyway - I do not know about sewing machines. I figured out how to wind 
the bobbin. Some fooling around got me a stich that looked pretty good 
on top but a wadded mess on bottom. I figured that might mean I need to 
adjust some tension on bobbin but see no way to do that.
	Thanks in advance if anyone should have any helpful suggestions.
