H. PADDED SWING-AWAY ARMRESTS (OPTION)
Swing-away armrests can be detached or can swing away to allow lateral transfers. They are height
adjustable (6" in 1" increments) by moving bolts (G) up or down in predrilled holes on armrest
bracket.
1. Height adjustment
a. Pull armrest straight out of the receiver.
b. Remove the indexing Bolt (H) and move it to the desired adjustment hole
c. If more height adjustment is required, the bracket can be inverted and re-attached.
d. Tighten the hardware to 63 in-lbs.
2. Angle adjustment
a. To Change the angle of the Armrest, Remove the Bolts (G)
b. Reposition to the required angle, Re-insert the hardware.
c Tighten the hardware to 63 in-lbs.
I. CASTERS
NOTE– Setting the wheelchair on a very flat table or a workbench makes this setting more accurate.
1. Adjusting Caster Angle
Checking for Caster Squareness:
Your Quickie wheelchair leaves the factory with the casters adjusted square. Any time you change
your wheelchair rear axle height, rear tire size, center of gravity position or camber tube, you
should check that the casters are still square. A caster that is not square will result in the caster lift-
ing off the floor as it rotates around the stem bolt and may also lift the front of the wheelchair up
and down. Check for squareness by placing your wheelchair on a flat, horizontal surface. Rotate
both forks so that the casters are towards the rear of the wheelchair. Place a square or pocket
level against the flat surface on the rear of the fork and note whether this surface is vertical
(square). If this surface is more than 1 degree away from vertical, your casters require re-squaring.
2. Re-squaring Your Casters
Locate the bolt (A) inside the right caster tube and loosen (Do not remove) using a 10 mm open
end wrench. Loosen this bolt enough to allow the teeth on the upper and lower splines (B) to
clear one another. The caster fork should pivot freely. Place the wheelchair on the floor so that the
two rear wheels and left caster contact the floor. Place some weight in the seat towards the rear
to help stabilize the chair. Place a square or pocket level against the flat surface of the fork and
pivot the fork until it is vertical (square) . With the fork vertical, engage the teeth of the two
splines to the closest mating position. Make certain that the teeth are properly engaged and not
crossed. Shine a bright light behind the mating spline teeth and check for proper teeth engagement.
Tighten the screw (A) to secure the spline mating position. The screw should be tightened to 100
in-lbs. (11.3 Nm) to ensure that it does not loosen during use.
Record the teeth engagement position of the splines on the right fork, and adjust the left fork in a
similar fashion to the same position. Reassemble both casters, and re-check that they are square.
Replace caps.
3. 3-D Perpendicular Alignment
The allen bolt adjustment (C) provides another dimension of adjustability in addition to the spline
system. The bolt may be loosened to relieve tension in the stem assembly. The caster angle may
then be fine-tuned and the bolt retightened.
4. Correcting a Pull to the Right or Left
Determine which direction the chair is pulling (right or left). Make the following adjustments to the
caster on that side of the chair:
a. Loosen the screw (A) inside the caster tube using a 10mm open-end wrench.
b. Loosen the screw on the upper spline (C).
c. Rotate the upper spline (D) to turn the caster fork toward the forward driving direction.
Turn the ring clockwise, and the fork will swing outwards. Turn the ring counterclockwise,
and the fork will swing inwards.
d. When the caster fork is correctly rotated forward, retighten the screws.
e. After making the desired adjustment, recheck the squareness of the casters.
f. Retorque bolt (A) to a minimum of 100 in-lbs. (11.3 Nm).
