E N G L I S H
ADJUSTING J3 HEIGHT, DEPTH AND
ANGLE
The first phase of the J3 Back hardware installation is complete. It
is now the appropriate time to have the user seated back in the
chair for personalizing the J3 Back. Do not have the user apply full
pressure on the back as it is not fully tightened to the full torque
requirements.
1. Height Adjustment (Fig. 12)
a. With the user in the chair, identify the desired height of the
back. Once identified, have the user remove pressure from
the J3 Back by leaning or sliding partially forward if possible
to allow the adjustment to take place.
b. Loosen the bracket nuts (A) and adjust the height of the back
shell to required position.
c. Securely tighten the bracket nuts (A). The recommended
torque specification is 75-85 in-lbs. (8.5 - 9.3 Nm).
NOTE– After height adjustment is complete, check that the width was not
inadvertently changed.
2. Depth/Angle Adjustment (Figs. 13, 14, 15, 16)
Please note there are two types of hardware that can be ordered–
standard hardware (Fig. 13) or the longer, adjustable hardware (Fig.
14). Both sets of hardware are adjusted the same, but the standard
hardware allows for 2 inches of depth adjustment (Fig. 13) while
the extended hardware (adjustable hardware) allows for a total of
3.4 inches of depth adjustability (Fig. 14).
a. To adjust J3 Back depth and angle loosen left and right bolts
(Fig. 16-B) on bracket slots.
b. Adjust depth and/or angle and securely tighten. The recom-
mended torque specification is 100-110 in-lbs. (11.3 - 12.4
Nm). Ensure that none of the depth adjustment nuts (Fig 16-B)
will slip or rotate.
c. If additional depth is needed, remove back from receivers.
Remove screws (Figs. 13-D, 14-D) from receiver using the
enclosed 4mm hex key, and reposition to desired depth.
Tighten screws to 25-35 in-lbs. (2.8 - 4 Nm).
WARNING
Ensure that all hardware has been properly tightened
once all adjustments have been completed and the J3
Back is ready for use.
