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 sur-
faces, it may be necessary to adjust the anti-tip wheels to
better suit your needs. The anti-tip wheels may need ad-
justment if the following occurs:
! When coming to a stop, your power chair tips forward
excessively.
! 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 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 Specialist 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.
