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 4 cap screws (A) (2 per side) that secure the camber tube clamp. Observe the ball
in the level (B), and rotate the camber tube (C) until the ball is centered in the level. The toe
is now set at zero.
Before tightening the screws (A), make certain that the camber tube is centered left-to-right
relative to the wheelchair frame. The end of the camber tube should be flush with the outer
most portion of the camber tube clamp. 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 4 cap
screws (A) (2 per side) that secure the camber tube clamp. Locate the flat surfaces on the
front and rear of the camber plugs (D). 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 (A), make certain that the camber tube is centered left-to-right
relative to the wheelchair frame. The end of the camber tube should be flush with the outer
most portion of the camber tube clamp. Torque the fasteners to 62 in-lbs. (7 Nm).
N. 4-LINK REAR SUSPENSION
Rear suspension can affect the stability of the wheelchair. To avoid a fall, use a
spotter and/or anti-tips when becoming familiar with new equipment.
1. Tuning the 4-Link Rear Suspension
a. To stiffen the suspension, turn the spring preload adjustor (E) clockwise (looking up at
the suspension system from underneath the wheelchair).
b. To soften the suspension, turn the spring preload adjustor (E) counter-clockwise (look-
ing up at the suspension system from underneath the wheelchair).
2. Alignment of Suspension Link Arms
Do not adjust the link arms (F). These are set at the factory to ensure proper tracking
and performance of the 4-Link Rear Suspension system.
Setting the Toe to Zero
Loosen the cap screws (G) (3 per side, unless equipped with anti-tips then 4 per side) that
secure the camber tube clamp. Observe the ball in the level (B), and rotate the camber tube
(H) until the ball is centered in the level. The toe is now set at zero.
Before tightening the screws (G), make certain that the camber tube is centered left-to-right
relative to the wheelchair frame, and the flat portions underneath outer camber tube clamp
are parallel side to side. The end of the camber tube should be flush with the outer most
portion of the camber tube clamp. Torque fasteners (G) 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 cap
screws (G) (3 per side, unless equipped with anti-tips then 4 per side) that secure the camber
tube clamp. Locate the flat surfaces on the front and rear of the camber plugs (D). Place an
object that is known to have an accurate 90° corner (such as a carpenters square, drafting tri-
angle, etc.) down on the flat horizontal surface 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.
