Fig. Fig. 2: If a door is being installed, first mount the door and tighten the hinge bolts lightly

  1. If a door is being installed, first mount the door and tighten the hinge bolts lightly.
  2.  

If the door has not been removed, determine which hinge bolts must be loosed to effect alignment.

  1. Loosen the necessary bolts just enough to allow the door to be moved with a padded prybar.
  2.  
  3. Move the door in small movements and check the fit after each movement.
  4.  

Be sure that there is no binding or interference with adjacent panels.

  1. Keep repeating this procedure until the door is properly aligned.

    Door panel lower edge-to-platform panel: 7mm plus or minus 2mm
     
    Door outer panel-to-platform panel (closed): 14mm plus or minus 1.5mm
     
    Door edge-to-roof panel: 5mm plus or minus 2mm
     
    Door edge-to-pillar: 5mm plus or minus 2mm
     
    Door edge-to-door edge (closed): 5mm plus or minus 2mm
