INSTALLATION OF THE RACKS
MOUNTING RACK TO GATE
A strong base on the gate is required for the mounting of the rack.
1. Manually open the gate and place a rack section to mesh with
the pinion (gear) on the Drive Unit. Mark the top of the rack
where it is in contact with the gate. Manually close the gate and
continue to mark the top of the rack with a marker until the gate
is fully closed.
2. Once the line is established, place the top edge of the rack on
it and mark the centers of the rack slots. The first rack should
start 20mm from the edge of the gate. Once the line is
established, place the top edge of the rack on it and mark the
centres of the slots in the rack on the gate. Drill and tap for 6mm
(1/4") screws.
3. Once the first section of the rack is mounted on the gate,
check that it meshes with the pinion gear on the drive unit.
4. When joining the remaining racks check the mesh by
placing a spare rack upside down (teeth facing upwards) and
putting it into mesh with the racks being joined (see Fig. 5). Do
this before tightening the racks. This will ensure that the drive
unit pinion can run along the racks without obstruction.
