Q R I
K. REAR WHEEL SPACING
1. Adjusting the Wheelbase Width
Adjusting the wheelbase width allows the rider the option to move the wheels closer or fur-
ther away from the hips. It also compensates for camber adjustment and gives the proper
wheel spacing to maximize pushing efficiency.
Adjust the wheelbase width by loosening the left and right capscrew (A) and moving the cam-
ber plug (B) in or out equally on both sides. Do not rotate the camber plug as this adjustment
is made because it will effect the toe-in/toe-out adjustment. Slide the Camber insert in or out
to establish the most effecient wheelbase width.
2. Adjusting Rear Wheel Spacing
Rear wheel spacing is measured as the gap between the top of the rear wheels and the back-
canes, this gap must be equal on both sides
ble depending on the options chosen.
NOTE– When setting the rear wheel spacing only make adjustments to one side of the chair at a time.
Loosening both sides will undo the toe setting.
To adjust the rear wheel spacing, the camber plugs (B) telescope in and out of the camber
tube (C) with hard stops at each end of travel. On the left side of the chair, loosen screw (A)
(the one closest to the camber tube). Slide the camber insert in or out to establish the
required wheel spacing. Tighten screw to 144 in-lbs. (16.3 Nm). Repeat on the right side of
the chair, matching the wheel spacing set on the left side.
L. CASTERS
NOTE– Setting the wheelchair on a very flat table or a workbench makes this setting more accurate.
1. 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 lifting off the floor as it rotates around the stem bolt
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)
from vertical, your casters require re-squaring.
2. Adjusting Caster Angle
For optimum performance, the caster housing should always be at a 90 degree angle to the
floor (perpendicular to the ground). This adjustment is made with an eccentric (offset)
attachment bolt mechanism.
a. To change the angle, place the chair on a flat surface (such as a table).
b. Remove the nuts (D) from the caster plate (E), You do not have to completely remove
the bolts. The caster plate is slotted at the top and bottom for adjustment purposes,
and is now free to be adjusted.

c. Place a large square
housing.
d. By rotating the eccentric washers (F) independently you can align the caster stem
perpendicular to the floor surface.
e. Re-attach the nuts, and tighten to 75 in-lbs.
f. Repeat the process for the other caster.
