The height needs to be adjusted so that the gate does not rest on the
reduction unit traction gear (Fig. 5, 6).
Holes with a diameter of 7 mm should be made to fix the rack into the
gate, and they should be threaded using a M8 type screw tap.
The pinion must have a clearance of 1 to 2 mm with respect to the rack.
