Q. FRAME WIDTH
The frame of the IRIS is built to accommodate growth from 10" to 18" wide using the three
strut tube assemblies. Moving one hole position on each side of the strut provides a 1"
frame width change.
1. Width Adjustment
a. Remove the bolts (C) from one side of the strut tubes (D) for all strut tubes.
b. Slide the adjustable extension (E) to the desired width according to the matrix in the
ordering guide.
c. Replace and tighten the bolts in all strut tubes.
d. Repeat on the other side.
IMPORTANT NOTE– The adjustment on each side of the chair should be exactly equal and the align-
ment of the holes must remain horizontal.
NOTE– Use a torque setting of 96 in.-lbs. when setting up frame width.
R. SEAT PAN
The seat pan of the IRIS is designed to accommodate depth adjustment.
Depth adjustment
a. Loosen and remove all bolts (F).
b. Adjust the seat pan to the desired depth.
c. Replace and tighten all bolts.
S. CUSHION INSTALLATION
a. Place cushion on seat pan with hook material side down. The beveled edge of the
cushion should be in front.
b. Press firmly into place.
T. REAR AXLE
1. To Mount and Remove Rear Wheels (optional)
Do not use this chair UNLESS you are sure both quick-release axles are locked. An unlocked
axle may come off during use and cause a fall.
NOTE– Axle is not locked until the quick-release button (A) pops out fully.
2. To Install Wheel
a. Depress quick-release button (A) fully. This will release tension on ball bearings at
other end.
b. Insert axle through hub of rear wheel (B).
c. Keep pressure on button (A) as you slide axle (C) into axle sleeve (D).
d. Release button to lock axle in sleeve. Adjust axle if it does not lock.
e. Repeat steps on other side.
3. To Remove Wheel
a. Depress quick-release button (A) fully.
b. Remove wheel by sliding axle (C) out of axle sleeve (D).
c. Repeat steps on other side.
4. Rear Wheel Axle Adjustment
Tight axle sleeves should be maintained for proper performance of the wheelchair.
a. To adjust the axle you will need a 3/4" wrench to turn the outside axle nuts.
b. You will also need a 1/2" wrench (E) to lodge the ball bearings (F), on the opposite
end of the axle, and prevent the axle from turning.
c. Turn the outside axle nut counter-clockwise to tighten.
d. There should only be zero to ten thousandths of an inch (.010) of play.
5. Weight Distribution
Weight distribution between the front and rear wheels is primarily adjusted by moving the
rear axles forward or rearward on the frame.
Moving the axles REARWARD provides better forward and rearward tipping stability.
