No. I didn't think of trying that because the saw actually likes a bit more manual downforce.
On the strength of your suggestion, I'll try that when I get home next week too.

Ya, that spring arrangement is strange. Tensioning the spring actually assists in lifting the blade, hence @David_R8 's suggestion for backing off the tension (less lift).
This is a very well written article Gerrit. I could only wish for a few photos.
Thank you.
For right now, you have hit the nail on the head.
By inside, I assume you mean inside of the bandsaw loop.
Thanks, I think I see now why I couldn't find one. I was looking for a classic eccentric shoulder not one with multiple flats. So I assume it has to be removed to select an appropriate pair of flats to obtain the right pinching force. That probably also means there are only 6 set points or so.
I'm not home till next wednesday, so I'll check it then along with the other suggestions I have received.
I hope no-one thinks I'm complaining though. The saw is a million times better than my best manual hack saw. I'm also quite pleased with the cut quality.

When you replaced the bearings (you did replace them right? 
they are dirt cheap to buy), one shaft on each set will have been an eccentric. Loosen the nut slightly, then turn the shaft using the hex next to the bearing to get the 0.025"+ setting for blade clearance. (the wierd angle of the bearing is an optical thing)

When you replaced the bearings (you did replace them right?
Actually no. I did not replace any of the bearings on the saw. They all seemed just fine.
I guess that will be added to my priority to do list.
So now I'm confused again Gerrit. Is the eccentric shaft round or with indexed flats?
When I loosened these Bolts,
nothing would turn and neither one appeared to have an eccentric shaft.
OK.
Am away babysitting my mom right now. Will do it when I get home in a week.
Thanks Gerrit.
You guys have lost meThis adjustment does what to the blade?
I believe it adjusts the blade pinch clearance for the guidance bearings against the blade.
Not that I have ever done it, but I wanted to! Mine are pinching the blade too tightly. I couldn't find the eccentric described in the user manual. Gerrit is showing me where it is.
Did you have difficulties installing the new blade?
Yes. It kept wanting to pop off the drive wheels and it's hard to get it between the bearings.
If I tighten the blade tension too much it stalls. If I loosen it too much it pops off. To get it to stay on I had to apply manual down pressure.
When I get home I will
1. Back off on the cutting spring which should increase cutting PRESSURE. Odd arrangement but if it works, it works!
2. Adjust the bearing clearance.
3. Run through the document Gerrit supplied above for other adjustments.
That's the plan anyway.
Of course that all has to be balanced with how horny mother nature is. I gotta plant seed asap.

The eccentric is the bolt holding the bearin
the nuts just loose, the excentric on underneath the bearing (guide) both sides (or should be). Same crappy casting everyone uses.
Can you send me a pic(s) of the tension pulley.
Will do. Won't be home till a week or so from now, but I'll take a photo for you when I can.
@gerritv , @Degen , @Tom O , @YYCHM and anyone else I missed.
I am home now.
The eccentric is on the outside not the inside. I bet that's an assembly issue because it's on the inside on other members saws and my manual says inside too.
There is no eccentric indexing. At first I thought there are no flats either. But they are there - just very hard to access. I had to make a thin wrench that was thin enough to fit between the bearing and the extension bar. The eccentric is a very tight friction fit.
After relieving the blade pinching force, the blade no longer pops off. Yippee!
Here is the drive @Degen, and the top gear is after that. Hope it shows whatever you need. The blade looks like it's touching the drive, but it isn't.
