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 Provider 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 Provider 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 curb if they are not adjusted correctly. Contact your Quantum Rehab Provider for more information.

To adjust the anti-tip wheels:

1. Loosen bolt A. See figure 21.

2. Remove bolt B.

3. Raise or lower the anti-tip wheel by 0.50 in. (1.25 cm) or 1 in. (2.54 cm) increments by aligning the appropriate adjustment holes. See figure 21.

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 be inflated to the psi/ bar/kPa rating indicated on the tire in order for the anti-tip wheels to be properly adjusted. The user must also be seated in the power chair in order to properly adjust the anti-tip wheels.
