5. Setting the Toe to Zero – Alternative Method
a.
Loosen the 2 cap screws (D) (1 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.
b.
Before tightening the screws (D), 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 (D) to
100 in-lbs. (11.3 Nm).
N. CENTER OF GRAVITY (CG) ADJUSTMENT
The most important adjustment on your Quickie wheelchair is the position of the rear axle. The center of gravi-
ty, wheel camber and wheelbase are all determined by the axle adjustment.
NOTE - Use a torque setting of 60 in.-lbs. when adjusting rear axle clamp bolts (E).
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 cap head screws (E). Slide camber tube assembly forward or rearward along frame tube . Retighten the
screws. 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 maneuver it with a spotter
to get a feel for the new adjustment.
