O. REAR AXLE
The most important adjustment on your Quickie wheelchair is the position of the rear axle. The center of gravi-
ty and wheel camber are determined by the axle adjustment.
1. Center of Gravity Adjustment
WARNING
The more you move your rear wheels forward, the more likely your chair will tip over backwards. Always make
adjustments in small increments, and check the stability of your chair with a spotter to prevent a tip-over. We rec-
ommend that you use anti-tip tubes until you adapt to the change and are sure you are not at risk to tip over.
Refer to additional Warnings in Section VI “Falls and Tip Over”.
NOTE–
Changes to the center of gravity may affect the rear seat height, toe-in/toe-out of the rear wheels and the
squareness of the casters. If you change your center of gravity position, re-adjust all of these settings if nec-
essary.
NOTE–
Adjusting your chair’s center of gravity will require re-adjusting the location of the wheel locks
(if provided). See for instructions on adjusting the wheel locks.
You can adjust your center of gravity position by moving the two axle plate and clamp assemblies (A) forward or
rearward on the seat tube (B). Moving the axle plate clamps forward shortens the wheelbase and lightens the
front end, making your chair more maneuverable. Moving the axle plates and camber tube rearward makes the
chair more stable and less likely to tip rearward.
To adjust the center of gravity location, remove both rear wheels. Loosen the 4 screws (C) (2 per side) that
secure the axle plates (A) to the seat tubes. Slide both camber tube clamps forward or rearward along the seat
tube to the desired position. Make sure both sides are adjusted symmetrically before tightening screws. Tighten
screws to 144 in-lbs. (16.3 Nm).
Once the camber tube clamps are secured, attach the rear wheels, occupy the chair and maneuver it with a spot-
ter to get a feel for the new adjustment.
2. Wheel Camber
Wheel camber, shown as angular relationship (D), provides greater side-to-side stability due to the increased
width and angle of the wheelbase. It also allows for quicker turning and greater access to the top of the han-
drims.
Wheel camber is determined by pairs of interchangeable camber plugs which are available from your authorized
supplier in 0º and 3° angles. You can remove the old camber plugs and replace them with new ones by loosening
the screws (E) and removing or adding the plug to the Camber tube ( F ).
3. Setting Toe-in toe-out to zero
NOTE–
A wheelchair equipped with 0° camber plugs cannot have a toe-in toe-out condition. This adjustment
is only required when using 3° camber plugs.
Toe refers to how well the rear wheels of the chair are aligned relative to the direction of travel. It affects how
well the chair will roll. Drag or rolling resistance is best when the wheel toe is set to zero.
