Anti-tip Wheel Adjustment
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.
NOTE: Each drive tire must be inflated to 35 psi (2.4 bar) in order for the anti-tip wheels to be properly
adjusted.
To adjust the anti-tip wheels:
1. Place an adjustable 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.
3. Place your wrench on the adjustable cam located on the other side of the locknut. See figure 21.
4. To adjust the anti-tip upward, turn the cam counterclockwise. To adjust the anti-tip downward, turn the cam
clockwise.
5. Tighten the locknut.
6. Make the same adjustment to the other anti-tip wheel.
WARNING! Consult your Quantum Rehab Specialist before attempting to change the anti-tip
height! Changing the anti-tip wheel height affects handling under deceleration!
WARNING! The higher you raise the anti-tip wheels, the more tendency your power chair has to
tilt forward when coming to a stop. You can compensate for this by making 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.
PROHIBITED! Do not remove the anti-tip wheels.
