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 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 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 deceleration!
WARNING! The higher you raise the anti-tip wheels, the more you increase your power chair’s tendency to tilt forward when coming to a stop. 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 further to the rear of your power chair.
To adjust the anti-tip wheels:
1.Remove the anti-tip wheel.
2.Remove the nut and bolt on the anti-tip bracket. See figure 21.
3.Raise or lower the anti-tip wheel.
4.Reinstall the nut and bolt on the anti-tip bracket.
5.Reinstall the wheel.
6.Raise or lower the other anti-tip bracket so that it is at the same height.
NOTE: Each drive tire must have 35 psi (2.4 bar) in order for the anti-tip wheels to be properly adjusted.
