TIRE
Follow these easy steps for a quick and safe repair for both pneumatic and solid tires:
1. Turn off the power to the controller.
2. Set the power chair up on blocks.
3. If you are changing a pneumatic tire, completely deflate it before removing the wheel.
4. Remove the drive wheel nut and washer from the axle. See figure 27.
5. Pull the wheel off the axle. Make sure that you keep the axle key.
6. Remove the nuts and washers from the wheel hub to separate the rim halves. See figure 28.
7. Remove the old tube from the pneumatic tire and replace it with a new tube or replace the entire assembly if
it is a solid tire.
8. Refasten the rim halves.
9. Slide the wheel back onto the axle. Make sure that the key is in the axle slot.
WARNING! Failure to ensure that the axle key is properly installed into the axle slot when
mounting the wheel can result in electronic brake failure, personal injury, and/or product damage.
10. Reinstall the drive wheel nut and washer onto the axle and tighten.
WARNING! Make sure both the nut and washer are reinstalled and tightened properly.
11. Inflate the pneumatic tire to the psi/bar/kPa air pressure rating indicated on each tire.
