Sunrise Medical JAY J3 BACK Mode D'emploi page 10

ENGLISH
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. 10)
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. 11, 12 &13)
Please note there are two types of hardware that can
be ordered– standard hardware (Fig. 11) or the longer,
adjustable 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 hardware (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. 13-B) on bracket slots.
b. Adjust depth and/or angle and securely tighten. The
recommended torque specification is 100-110 in-lbs.
(11.3 - 12.4 Nm). Ensure that none of the depth
adjustment nuts (Fig 13-B) will slip or rotate.
c. If additional depth is needed, remove back from
receivers. 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).
WARNING
Ensure that all hardware has been properly tightened
once all adjustments have been completed and the
J3 Back is ready for use.
WARNING
To ensure optimal security of the back fitment, the
locking pin must be inserted before the backrest can be
used, (Fig. 14 & 15).
