2. Wheel Camber
The wheel camber adjustment provides greater side-to-side stability due to the increased width and angle of
the wheelbase. The wheel camber adjustment also allows for quicker turning and greater access to the top of
the handrims.
Wheel camber is preset at the factory at 3°. You can achieve a 0°camber by removing the axle sleeve(C) and
Camber washers(D) and flipping them 180°.
NOTE–
Adjusting your chair's center of gravity will require re-adjusting the location of the wheel locks
(if provided). See Section T for instructions on adjusting the wheel locks.
3. Wheel Base 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
efficiency.
a. Loosen the nuts and reposition the axle sleeve (A) to the desired width.
b. Retighten nuts to a torque of 360 in-lbs.
4. Seat Height Adjustment
Seat height can be adjusted by loosening the large axle sleeve nuts(B). enough so that the axle washers will
move along the axle plate vertically in the slots. Be sure to adjust both sides of the chair to an equal vertical
seat height adjustment.
NOTE– Be sure the ridges for indexing washers are fully engaged in Axle plate grooves before tightening.
NOTE– A front caster adjustment should be made to correspond with any change in seat height.
NOTE– In most cases the Anti-tip Receiver is used as the internal axle nut in this assembly. Loosen the
external axle sleeve nut enough so that the whole assembly can be adjusted up or down. Tighten
the axle sleeve nut to 360 in-lbs when the adjustment is complete.
