Caster Angle Adjustment
When you change the seat angle, you must also change
the caster angle so that the caster barrels remain at a 90°
angle to the ground. See figure 40. There are 7 possible
angles with a quick-release caster and 13 possible
angles with a bolt-on caster.
NOTE: There are two screws that fasten the caster
barrel assembly to the frame. The nuts that secure the
screws are eccentric. The eccentric nuts should be
positioned to the appropriate setting for the desired
angle. A right-angle square is recommended for
aligning the caster barrels to ensure 90° alignment to
the ground.
WARNING! If your wheelchair is
equipped with a transit securement
system, the caster angle should only
be adjusted by a Quantum Rehab
Provider or a qualified technician.
To change the caster angle:
1. Remove the screws that fasten the caster wheel
assembly to the frame.
2. Reposition the eccentric nuts to the desired setting
and reinsert the bolts.
3. Tighten the screws.
NOTE: Make sure that both casters are adjusted to
the same angle.
Caster Wheel Removal
The casters can be removed one of two ways, depend-
ing on caster style.
To remove the bolt-on caster wheel:
1. Remove the hardware that attaches the caster wheel
to the frame of your wheelchair. See figure 41.
2. Repeat for the other side if necessary.
To remove the quick-release caster wheel:
1. Press the quick-release button and pull the caster
wheel off. See figure 42.
2. Repeat for the other side if necessary.
