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 coming to a stop, your power chair tips forward excessively. The anti-tip wheels constantly rub the ground.
To adjust the anti-tip wheels:
1.Place a wrench on the inner locknut of the anti-tip bracket located right after the shock strut. See figure 20.
2.Turn the locknut counterclockwise to loosen the cam.
3.Place your wrench on the adjustable cam located on the other side of the locknut.
4.To adjust the anti-tip upward, turn the cam counterclockwise. To adjust the anti-tip downward, turn the cam clockwise. See figure 21.
5.Tighten the locknut.
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 authorized Quantum Rehab Provider make a small adjustment to the pre-programmed deceleration setting in the controller or by moving the seat assembly farther to the rear of your power chair.
WARNING! Consult your authorized Quantum Rehab Provider before attempting to change the anti-tip wheel height! Changing the anti-tip wheel height affects handling under deceleration!
PROHIBITED! Do not remove the anti-tip wheels.
