Fastening the rack
1
Release the operator.
2
Rest the rack on the pinion.
3
Weld or fasten the rack to the gate along its entire length.
To assemble the rack modules, use an extra piece and rest it under the join, then fasten it in place using two clamps.
Adjusting the pinion-rack coupling
Open and close the gate manually.
Adjust the pinion-rack coupling distance using the threaded feet (vertical adjustment) and the holes (horizontal adjustment).
The weight of the gate must not bear down upon the operator.
