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 either
of the following occur:
n When accelerating, your power chair tips rearward excessively.
n The anti-tip wheels constantly rub the ground.
WARNING! Consult your Quantum Rehab Specialist before attempting to change the anti-tip wheel height!
Changing the anti-tip wheel height affects handling under deceleration!
WARNING! The higher you raise the anti-tip wheels, the more you increase your power chair’s tendency to
tilt rearward when accelerating. You can compensate for this by having your Quantum Rehab Specialist
make a small adjustment to the pre-programmed acceleration setting in the controller or by adjusting the
seat assembly.
WARNING! The anti-tip wheels may cause trouble when ascending or descending a kerb if they are not
adjusted correctly. Contact your Quantum Rehab Specialist for more information.
To adjust the anti-tip wheels:
1. Loosen bolt A. See figure 18.
2. Remove bolt B.
3. Raise or lower the anti-tip wheel by 1.27 cm or
2.5 cm increments by aligning the appropriate
adjustment holes. See figure 18.
4. Insert bolt B into the appropriate hole for the desired
anti-tip height and tighten.
5. Tighten bolt A.
6. Raise or lower the other anti-tip wheel so that it is at
the same height.
PROHIBITED! Do not remove the anti-
tip wheels.
NOTE: Each drive tire must have at least 2 bar
(30 psi) in order for the anti-tip wheels to be prop-
erly adjusted. The user must also be seated in the
power chair in order to properly adjust the anti-tip
wheels.
