IV. INSTALLATION, USE, AND ADJUSTMENTS
C. Adjusting Height, Depth, and Angle
Once the initial installation is complete, adjustments can be made with the user seated in the chair for a
personalized fi t. Ensure that the user does not apply their full weight to the back until the hardware has
been fully tightened to the specifi ed torque requirements.

D-Fig. 19 for FP).
c.
Move back to the correct height, and tighten the nuts to 8.5-9.6 Nm [75-85 in-lbs].
2.
Depth and angle adjustment
Depth adjustment varies with the type of hardware ordered. HD and FP hardware have
approximately 2 inches of depth adjustment.

If additional depth is needed, remove the JAY FIT 2U Back from the receivers. Remove the
screws (Fig. 16 for HD, Fig. 17 for FP) from the receiver using a 4mm hex key and reposition
the hardware to the desired depth. After adjusting to the correct depth, tighten the screws to
2.8-4 Nm [25-35 in-lbs].
