ADJUSTING J3 HEIGHT, DEPTH AND
ANGLE
The first phase of the J3 Back hardware installation is com-
plete. 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 tight-
ened to the full torque requirements.
1. Height Adjustment (Fig. 10)
a. With the user in the chair, identify the desired height of
the back. Once identified, have the user remove pres-
sure from the J3 Back by leaning or sliding partially for-
ward 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 recommend-
ed 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. 11, 12, 13 & 14)
Please note there are two types of hardware that can be
ordered– standard hardware (Fig. 11) or the longer, adjust-
able hardware (Fig. 12). Both sets of hardware are adjusted
the same, but the standard hardware allows for 2 inches (5
cm) of depth adjustment (Fig. 11) while the extended hard-
ware (adjustable hardware) allows for a total of 3.4 inches
(8,65 cm) of depth adjustability (Fig. 12).
a. To adjust J3 Back depth and angle loosen left and right
nuts (Fig. 14-B) on bracket slots.
b. Adjust depth and/or angle and securely tighten. The rec-
ommended torque specification is 100-110 in-lbs. (11.3 -
12.4 Nm). Ensure that none of the depth adjustment nuts
(Fig 14-B) will slip or rotate.
c. If additional depth is needed, remove back from receiv-
ers. Remove screws (Figs. 11-D, 12-D) from receiver
using the enclosed 4mm hex key, and reposition to
desired depth. Note: Prior to replacing the screws the
application of a suitable medium strength threadlocker
e.g. loctite 243 is strongly recommended to the receiver
and screw threads, if the back is to be repositioned.
Tighten screws to 25-35 in-lbs. (2.8 - 4 Nm).
Ensure that all hardware has been properly tightened
once all adjustments have been completed and the
J3 Back is ready for use.
To ensure optimal security of the back fitment, the lock-
ing pin must be inserted before the backrest can be
used, (Fig. 15 & 16).
