INSTRUCTIONS: ADJUSTING THE OBSTACLE CLEARANCE SPACE
The proper obstacle clearance space is 25 mm ± 0.5 mm. If the frame is distorted, the gap for the
passage of moving obstacles in the upper part of the unit will not be adequate.
•
If you do not obtain this measurement, it means the unit is sagging or bending towards the middle.
•
This gap, as well as overall leveling, is critical to proper operation.
Adjust the position of the shims [B] in relation to the anchors [A] to adjust the gap.
