2. Use the 3mm Hex key supplied to remove the 3 fixings that fasten the shell
into the base plate. The shell, eyeball and T plate should now be free of the
base plate.
3. You will notice that the eyeball features a slight lip on one edge. This is the
sun-visor and should always be on the top of the eyeball perpendicular to
the ground. Adjust the eyeball so it is in the desired orientation within the
shell and hold in place.
4. Replace the T shaped retainer plate by re-fastening the cross headed screw
removed in step 1. To do this, carefully flip the shell upside down, taking
care to keep the eyeball in position. Fit the T bar in position so that the holes
line up correctly with the holes of the shell. The cross headed retainer screw
fastens the hole at the bottom of the T bar into the threaded boss on the
shell. The two holes at each end of the T’s cross bar fit over the bosses
through which the shells outer hex fastening are positioned. Ensure the T
bar is screwed tightly into the shell to prevent movement of the eyeball prior
to finally locking into place on the base plate.
