ANTI-TIP WHEELS
The anti-tip wheels are an integral part of your power chair’s mid-wheel design because they provide you with stability during deceleration. The anti-tip wheels are preset at the factory to a height of 3/4-in., which is measured from the ground to the bottom of the wheel. This is the ideal setting for most power chair users. However, you may encounter situations where you may need to adjust the anti-tip wheels. For instance, if you drive your power chair on surfaces such as deep pile carpeting, you may notice that the anti-tip wheels have a tendency to drag on the carpet. In this case, you may need to raise the anti-tip wheels. If you drive your power chair primarily on smooth surfaces such as linoleum or tile, you may find that you tip forward more than is comfortable for you. (This may be more apparent for lighter users.) In this case, you may need to lower the anti-tip wheels.
WARNING! Consult your authorized Pride 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 forward when coming to a stop. You can compensate for this by having your authorized Pride provider 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.
Anti-Tip Wheel Adjustment
You will need a 1/2-in. wrench and socket and a Phillips head screwdriver.
To adjust the anti-tip wheels:
1.Make sure that the manual freewheel levers are in the drive position.
2.Unplug the controller connectors from the electronics tray.
3.Remove the seat. See V. "Disassembly."
4.Unplug the left and right motor connectors.

| 6. | Remove all four seat post ball detent pins (4) and remove the |
| | |
| | seat posts. | | |
| 7. | Remove both left and right shrouds by loosening and removing | | |
| | the four Phillips head screws. Two screws fasten each shroud | | |
| | section to the frame. These screws are located on the top of | | |
| | the shroud near the seat post holes. | | |
| 8. | Locate the anti-tip adjustment nut. See figure 17. | | |
| 9. | Use a 1/2-in. wrench to turn the adjustment nut. To lower the | | |
| | anti-tip wheels and soften the suspension, turn the adjustment | | |
| | nut counterclockwise. To raise the anti-tip wheels and stiffen | | |
| | the suspension, turn the adjustment nut clockwise. Make the | | |
| | same adjustment on both anti-tip wheels. | | |
| 10. Reinstall the left and right shrouds. | | |
| 11. | Reinstall the four seat posts. | | |
| 12. Reinstall both battery boxes. | | |
