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:
n When coming to a stop, your power chair tips forward
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 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.
NOTE: Each drive tyre must be inflated to 2.4 bar/35 psi (if equipped with pneumatic tyres) and
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. Place a spanner on the inner locknut of the anti-tip bracket located in front of the shock strut. See figure 16.
2. Turn the locknut counterclockwise to loosen.
3. Place a spanner on the adjustable cam located on the other side of the locknut. To adjust the anti-tip upward, turn
the cam counterclockwise. To adjust the anti-tip downward, turn the cam clockwise.
4. Tighten the locknut
5. Raise or lower the other anti-tip wheel so that it is at the same height.
