4.13 Caster Angle Review
Please put the wheelchair on a flat table while adjusting in order to ensure the
accuracy.
4.13.1 Make sure the caster adapter is 90 degrees to the ground.
4.13.2 Once you adjust the seat height, front caster, rear wheel and the center of
gravity position, please make sure the caster adapter is 90 degrees to the
ground.
4.13.3 Rotate both forks so that the casters are towards the rear of the wheelchair.
Place a square or pocket level against the flat surface on the rear of the fork
and note whether this surface is vertical. If this surface is more than 2 degrees
away from vertical, your casters require re-squaring. (See Figure 4.29)
4.13.4 Use the tool to loosen the screws and nuts on the caster adapter. (See Figure
4.30)
4.13.5 Adjust the caster adapter to 90 degrees toward the ground.
4.13.6 Place a square or pocket level against the flat surface on the rear of the fork
and note whether this surface is vertical. (See Figure 4.29)
4.13.7 Place the eccentric hexagonal pads in the appropriate direction, and lock
the screws and nuts of the front caster adapter. (See Figure 4.31)
