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 handrims.
Wheel camber is determined by pairs of interchangeable camber plugs which are available
from your authorized supplier in 0º, 3°, and 6º angles.
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 adjust-
ment is only required when using 3° and 6° camber plugs.
Toe refers to how well the rear wheels of the chair are aligned relative to the ground. It
affects how well the chair will roll. Drag or rolling resistance is optimally minimized when the
wheel toe is set to zero.
Setting the Toe to Zero
Loosen the 2 cap screws (E) (2 per side) that secure the camber tube clamp. Observe the ball
in the level (G), and rotate the camber tube (F) until the ball is centered in the level. The toe
is now set at zero.
Before tightening the screws (E), make certain that the camber tube is centered left-to-right
relative to the wheelchair frame. There should be an equal gap on both sides or none at all.
Torque fasteners (A) to 62 in-lbs. (7 Nm).
Setting the Toe to Zero– Alternative Method
Place the entire wheelchair on a flat horizontal table or ground surface. Loosen the 2 cap
screws (E) (2 per side) that secure the camber tube clamp. Locate the flat surfaces on the
front and rear of the camber plugs ( I ). Place an object that is known to have an accurate 90°
corner (such as a carpenters square, drafting triangle, etc.) down on the flat horizontal sur-
face and up against the flat of the camber plug. Rotate the camber tube and plug assembly
until the flat surface of the camber plug is parallel to the measuring tool.
Before tightening the screws (E), make certain that the camber tube is centered left-to-right
relative to the wheelchair frame. There should be an equal gap on both sides of the wheel-
chair or none at all. Torque the fasteners to 62 in-lbs. (7 Nm).
E. REAR WHEEL AXLE NUT ADJUSTMENT
Tight axle sleeves should be maintained for proper performance of the wheelchair.
a. To adjust the axle (G) you will need a 3/4" wrench to turn the outside axle nuts (H).
b. You will also need a 1/2" wrench to lodge the ball bearings (I), on the opposite
end of the axle, and prevent the axle from turning.
c. Turn the outside axle nut (H) clockwise to tighten.
d. There should only be zero to ten thousandths of an inch (.010") of play.
