Blade Adjustment

[Old Toolman]

Where can I get some instruction and guidance and blade adjustment particularly the back and forward oscillation of the blade.  I am new to scrolling and just purchased a Delta 40-695.  Their manual has very little on blade adjustment.  Thanks.

On the left side, under "Reviews" click on Dewalt tune-up. 
My understanding is that although Delta changed the outside of the machine slightly, the internal workings are still identical to the 788.  I used this info to get my 40-690 running much straighter. 

Good Luck
