4. 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°, 6° and 9° 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 (A) (1 per side) that secure the camber tube clamp. Observe the ball
in the level (C), and rotate the camber tube (B) 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. There should be an equal gap on both sides or none at all.
Torque fasteners (A) to 144 in-lbs. (16.3 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 (A) (1 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. There should be an equal gap on both sides of the wheel-
chair or none at all. Torque the fasteners to 144 in-lbs. (16.3 Nm).
K. GT W/ XTR SUSPENSION REAR AXLE
The most important adjustment on your Quickie wheelchair is the position of the rear axle.
The center of gravity, wheel camber and wheelbase are all determined by the axle adjustment.
NOTE: Use a torque setting of 100 in.-lbs. when adjusting rear axle.
1. Center of Gravity
Moving the center of gravity to the front will lighten the force required to turn the chair.
The further back the axle and clamp, the more stable the chair becomes.
The center of gravity is adjusted by moving the rear axle and clamp forward or backward on
the frame. Moving the axle and clamp forward will increase your turning speed and lighten
the front end.
IMPORTANT NOTE: Changing the center of gravity increases the risk of a fall or tip over. Be very careful
to assure the chair will not tip over backwards when tilted.
2. To Move Center of Gravity
Loosen bolts (E). Slide camber tube assembly forward or rearward along frame tube (F).
Retighten bolts. Be sure to measure the new position for evenness on both sides of the chair.
Once the axle plate clamps are secured, attach the rear wheels, occupy the chair and maneu-
ver it with a spotter to get a feel for the new adjustment.
3. Wheelbase Width Adjustment
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 nut (G) and repositioning the axle sleeve (H) in
its corresponding hole. Make sure the axle sleeve (H) spacing is equivalent on both sides of
the chair. Retighten nuts.
