ENGLISH
ADJUSTMENT
1. Open the air valve by twisting it counterclockwise. If your
cushion comes with two valves, open both valves using the
same technique. (Fig. 7)
2. Attach the rubber hose on the pump to the end of the valve.
Inflate the cushion insert with the pump until just before the
cushion begins to arch. (Fig. 8)
3. Remove the pump hose from the valve and close it by
twisting it clockwise. (Fig. 9)
4. Sit on the J3 Cushion, with the AIR insert installed, in your
normal sitting position with armrests and footrests properly
positioned. (Fig. 10)
5. Slide your hand beneath your buttocks to locate your
lowest bony prominence, usually the ischial tuberosites. If
necessary, your clinician or caregiver should assist you.
(Fig. 11)
6. Leaving one hand in place beneath the lowest bony
prominence, use the other hand to open the valve. As air
is released from the cushion insert, you will begin to sink
into it. When your fingertips touch its base, close the valve.
Approximately 1/2" (13 mm) of air should be between your
lowest bony prominence and the base of the cushion. (Fig.
12)
IMPORTANT ADJUSTMENT NOTES
• Your J3 Cushion with AIR insert may have been ordered
with two valves, one on each side of the cushion. If you
have two valves, steps 1-6 above should be repeated for
each valve. Two valves indicate that your cushion insert is
divided in the middle. You, your clinician or caregiver should
locate the lowest bony prominence on the same side as the
air valve used to adjust the cushion.
• You, your clinicians or caregivers should check the cushion
insert daily to ensure that you have not bottomed out (ie.
lost air and are now sitting on the base of the cushion). If
you have bottomed out, the protective value of the cushion
insert is lost. You should also check to be sure the cushion
insert is not over-filled with air. The cushion insert will work
best with approximately 1/2" (13mm) of air between you
and its base.
• The AIR insert may be affected by changes in altitude.
You may have to repeat steps 1-6 above as you change
altitudes.
