FASTENING THE RACK
 If the rack is already set up, the next step should be to adjust the rack-and-pinion coupling distance, otherwise,
fasten it:
- release the gearmotor (see RELEASING THE GEARMOTOR paragraph);
- rest the rack above the gearmotor pinion;
- 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 joint, then fasten it using two clamps.
ADJUSTING THE PINION-RACK COUPLING
Manually open and close the gate and adjust the pinion-rack coupling distance using the threaded feet (vertical
adjustment) and the holes (horizontal adjustment). This prevents the gate's weight from bearing down on the
operator.
