• 4mm hex key
• 10mm box end wrench
• 5/8" box end wrench
Installing the 4-Point hardware
1. loosen the clamp screws (a) with the supplied 4mm
hex key and slip the clamps around the Back canes
(B).
2. The mounting hardware should be at equal heights on
each back post (Fig. 8) and parallel to the seat frame
(Fig. 7).
3. Hand tighten clamp screws (a). loosen bracket nuts
(c) and Mounting Pin bolts (F) using the supplied
10mm box-end wrench until hardware can move easily
in all directions
notE:
For large tube diameters, clamp screws may have to
be removed completely.
4. attach the J3 Back by inserting left and right Mounting
Pins (D) in the left and right latch Receivers (E).
5. Install back to the approximate location, relative to both
chair and user.
6. Tighten bolts on the inside of the Mounting Pin (F).
Torque to 100 - 110 in-lbs.(11.3 - 12.4 Nm).
notE:
Receivers may require additional lateral adjustment
to ensure proper alignment.
7. Tighten bracket nuts (c). Torque to 75 - 85 in-lbs. (8.5 -
9.3 Nm).
notE:
Back height may require additional adjustment to
ensure proper fit to the user.
