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:
When accelerating, your power chair tips rearward excessively.
The anti-tip wheels constantly rub the ground.
WARNING! Consult your Quantum Rehab Dealer 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 Dealer 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 Dealer for more information.
To adjust the anti-tip wheels:
1. Loosen bolt A. See figure 13.
2. Remove bolt B.
3. Raise or lower the anti-tip wheel by 1.25 cm
(0.5 in.) or 2.54 cm (1 in.) increments by
aligning the appropriate adjustment holes. See
figure 13.
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 pneumatic drive tyre must be inflated
to the psi/bar/kPa air pressure rating indicated on
the tyre to be properly adjusted. The user must also
be seated in the power chair in order to properly
adjust the anti-tip wheels.
