Seat Height Adjustment
Front Seat Height
The front seat height can be adjusted in ½" increments by repositioning the caster wheel within the fork.
1. Use two 4mm Allen wrenches to remove the cap screws and push the internally threaded axle from one
hole location and move up or down to the desired location.
2. Reposition the two 6mm screws and tighten to 80 in./lbs.
3. Resquare caster wheels.
Setting Toe to Zero
NOTE: A wheelchair equipped with 0° camber plugs cannot have a toe-in toe-out condition. This
adjustment is only required when using 2°, 4°, 6° and 8° camber adapters.
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.
To Set Toe to Zero:
1. Remove the lower base mounts by removing two bolts per side using a 3mm Allen wrench. If anti-tips
are present, the image will look different, but the process is the same.
2. Adjust the camber tube so it is centered in the mounts and rotate the tube until the camber is facing
upward, relative to the ground if the chair is upright.
3. Reinstall the lower basemounts with the hardware loose.
4. Tighten the bolts in the sequence shown below (1,2,3,4) to 70 in/lbs.
NOTE: Ensure the camber tube is perpendicular to the seat frame rails. Ensure the towers and
clamps are aligned identically on both sides.
