Hi Jim,
Here is the part beneath the table.

Again loosen 2 cap screws holding the pins and open them wider.
Loosen the cap screws C and move the bracket back ( the bearing is fixed on this bracket and this is te only way to set it up.
Now that everything is free.
** Make sure the power is OFF and remove the plug from the socket.**
Start to tension and line up the blade.

Loosen the 2 capscrews (yours may have only 1) on the top wheel slide They are in the oval recess shown at the top of the wheel.
Tighten the blade to the recommended tension and turn the top wheel by hand, carefully, it is easy to catch fingers.
I usually stick a screwdriver through the spokes, not too far, it will get caught.
Once you have the wheels and blade spinning merrily, you can use the triangular shaped handle on the back ( C in Fig.20. ) to position the blade.
When that is running to your satisfaction, bring the lower guide block forward until the bearing is just clear of the blade, nip the screws C.
Now push one guide pin in just clear of the blade, (You can push it in and use a 0.010" feeler gauge if you wish) and lock with the cap screw.
Run the top wheel again to check the pin is not pushing the blade.
Repeat with the other pin. Then loosen the screws C and adjust the bracket so that the pins sit just behind the teeth of the blade and the bearing sits just behind the back of the blade. Tighten screws C.
Finally the top guide, Loosen screw E and bring the whole block forward until the pins are just behind the teeth again. Tighten screw E.
Push a pin in until it just clears the blade, check by turning the top pulley, adjust the other pin and lock the screws C.
Now the bearing G is brought forward by loosening screw H, this screw holds the bearing in position IN 2 WAYS.
The first thing is to move the shaft and bearing forward until it is just clear of the blade.
Then at the rear of the shaft is a screwdriver slot, the bearing is set on an eccentric and this slot enables you to move the bearing so that ONLY THE VERY OUTER EDGE OF THE BEARING IS IN CONTACT WITH THE BLADE. THIS SETTING IS VERY IMPORTANT.
Run the top wheel and check all is ok. Tighten cap screw H.
Job done, close up machine, plug in to electrical socket, switch on. seeemples 
Any problem let me know, this way the machine is set up properly and you can then have a look at the video instructions (which are very good)
