motor plate securing screw on the belt side with the
9/16” box end wrench.

the motor plate to lift higher than the left side. By
pushing down on the right front side you can level
the plate and then tighten the front, right screw to
secure in a level position.
15. Tighten the rear securing bolts with the two 9/16”
