receivers by inserting left and right mounting
pins (F) in the left and right receivers (H).
b. Locate the back to the approximate location
relative to both the chair and the user.
c. Tighten bolts on the inside of the mounting
pin (I) (Fig. 15) to a torque of 100-110 in-lbs
(11.3-12.4 Nm).
d. Tighten the bracket nuts (E) to a torque of
75-85 in-lbs (8.5-9.3 Nm).
e. Test the back release by pressing the release
levers (G) forward and removing the back
off the chair. Proper alignment of the
mounting hardware and back is correct when

and release of the back assembly.

smoothly.

on back canes (C).
d. Using a 5/8" wrench, loosen the nut (D) that
secures the lower mounting pin (E) so that it
slides fore and aft.
e. Slide lower receiver up (F) until it surrounds
the lower mounting pin (E).
NOTE - Leave 1/8" to 1/4" of space between the
bottom of the lower mounting pin (G) and the
bottom of the lower receiver channel (H)
f. Once properly aligned, tighten the hardware
receiver clamp screws (B). The recommended
torque is 75-85 in-lbs (8.5-9.4 Nm). Then
tighten the lower mounting pin nut (D) and
torque to 100-110 in-lbs (11.3-12.4 Nm).
