6. Preposition the Mount Links so that the Mount
Shaft Base that receives the Pitch Mount Shaft is
located in the lateral 1/3 of the clients torso on
the side which you intend to use the WREX Arm.
7. Snug but do not tighten the six Clamp Screws
using the Large T-Wrench. Add enough
tension so that the joints do not move easily
but can be repositioned if required to optimize
the arm alignment.
Note: Do not tighten the Clamp Locking Set
Screws at this time.
8. Hold the Pitch Mount Shaft so that the black Pitch
Pivot is at the proximal end, the hole through the
Pitch Pivot is in the line of progression of the chair
and the plate of the pivot is facing laterally. Insert
the Pitch Mount Shaft into the Mount Shaft Base.
Snug but do not tighten the Shaft Screws on the
Mount Shaft Base.
9. With client sitting in the chair align the square
hole in the Pitch Pivot approximately 1 ½ inches
above their shoulder.
