6. Peeping into the square hole of the back frame, check the position of the massager to adjust.

When the massager has been raised excessively : Turn the up/down detection gear clockwise to adjust.
When the massager has been lowered excessively : Turn the up/down detection gear counterclockwise to adjust.
While adjusting the distance between the square hole and Guide roller assy. to 0 ±5mm, check by using the up/down
adjustment button found on the manual operation panel of the controller.
