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 ROHO 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 twist-
ing it clockwise. (Fig. 9)
4. Sit on the J3 Cushion, with the DRY FLOATATION
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 promi-
nence, 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.

IMPORTANT ADJUSTMENT NOTES
• Your J3 Cushion with DRY FLOATATION
been ordered with two valves, one on each side of the cush-
ion. If you have two valves, steps 1-6 above should be
repeated for each valve. Two valves indicate that your cush-
ion insert is divided in the middle. You, your clinician or care-
giver 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 DRY FLOATATION
in altitude. You may have to repeat steps 1-6 above as you
change altitudes.
