Foot Platform Angle Adjustment

Anti-Tip Wheels
The anti-tip wheels are designed to give your power
chair increased stability on rough surfaces. The anti-tip
wheels are preset at the factory for smooth surfaces or
indoor use only. If you plan on using your power chair
on rough surfaces, it may be necessary to adjust the
anti-tip wheels to better suit your needs. The anti-tip
wheels may need adjustment if the following occurs:
When coming to a stop, your power chair tips for-
ward excessively.
The anti-tip wheels constantly rub the ground.
WARNING! Consult your Quantum
Rehab Provider before attempting to
change the anti-tip wheel height!
Changing the anti-tip wheel height
affects handling under acceleration!
WARNING! The higher you raise the
anti-tip wheels, the more you increase
your power chair’s tendency to tilt
forward while decelerating. You can
compensate for this by having your
Quantum Rehab Provider make a small
adjustment to the pre-programmed
deceleration setting in the controller
or by moving the seat assembly farther
to the back of your power chair.
PROHIBITED! Do not remove the anti-
tip wheels.
NOTE: Each drive tire must be inflated to the psi/bar/
kPa air pressure rating indicated on the tire for pneu-
matic tires. The user must also be seated in the power
chair in order to properly adjust the anti-tip wheels.
To adjust the anti-tip wheels:
1. Loosen bolt A. See figure 23.
2. Remove bolt B.
3. Raise or lower the anti-tip wheel bracket. Each hole
is in 0.50-in. (1.27-cm) increments.
4. Reinstall bolt B.
5. Tighten bolt A.
6. Raise or lower the other anti-tip wheel so that it is
at the same height.
