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 spanner on the inner locknut of the anti-tip bracket located right after the shock strut. See figure 21.
2. Turn the locknut anticlockwise to loosen the cam.
3. Place the spanner on the adjustable cam located on the other side of the locknut.
4. To adjust the anti-tip upward, turn the cam anticlockwise. To adjust the anti-tip downward, turn the cam
clockwise. See figure 22.
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
Quantum Rehab Dealer 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 Quantum Rehab Dealer before attempting to change the anti-tip wheel
height! Changing the anti-tip wheel height affects handling under deceleration!
PROHIBITED! Do not remove anti-tip wheels.
NOTE: Each drive tyre must be inflated to the psi/bar/kPa air pressure rating indicated on the tyre if equipped
with pneumatic tyres. The user must also be seated in the power chair in order to properly adjust the anti-tip
wheels.
