GT WITH XTR SUSPENSION REAR AXLE
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 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 (A). Slide camber tube assembly forward or rearward along frame tube (B). 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 maneuver 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 further away from the
hips. It also compensates for camber adjustment and gives the proper wheel spacing to maximize pushing effi-
ciency.
Adjust the wheelbase width by loosening the nut (C) and repositioning the axle sleeve (D) in its corresponding
hole. Make sure the axle sleeve (C) spacing is equivalent on both sides of the chair. Retighten nuts.

REAR WHEEL AXLE NUT ADJUSTMENT
To adjust the axle you will need a 3/4" wrench to turn the adjustment nut (E). You will also need a 1/2" wrench
to securely hold the ball detent end of the axle (F) to prevent it from turning.
If the wheel and axle (G) will not lock into the camber plug then the axle requires adjustment. Turn the nut (E)
counter-clockwise approximately 1/4 revolution and try to lock the axle into the camber plug. If it doesn't lock,
continue making small nut adjustments until it securely locks.
If the wheel is locked on the chair but there is excessive wheel play (the wheel hub can be pushed back and
forth on the axle) then adjust the nut clockwise until there is no perceptible gap between the wheel and camber
tube and the axle is securely locked onto the chair.
CAUTION– Quick-release button (H) must be flush with the edge of the wheel hub for detent balls (F) to be
engaged.
G. REAR WHEEL SPACING
Rear wheel spacing is measured as the gap between the top of the rear wheels and the backcanes, and is shown
as dimension (M) Factory settings will be as narrow as possible depending on the options chosen.
NOTE–
When setting the rear wheel spacing only make adjustments to one side of the chair at a time.
Loosening both sides will undo the toe setting.
To adjust the rear wheel spacing, the camber inserts (I) telescope in and out of the camber tube (K) with hard
stops at each end of travel. On the left side of the chair, loosen screw (L) (the one closest to the camber tube).
Slide the camber insert in or out to establish the required wheel spacing. Tighten screw to 144 in-lbs. (16.3 Nm).
Repeat on the right side of the chair, matching the wheel spacing set on the left side.
