CARE AND MAINTENANCE
TYRES AND TUBES
If your Quantum Dynamo ATS is equipped with pneumatic tyres, you
should check the air pressure at least once a week. This prolongs the
life of your tyres and helps to ensure the proper operation of your chair.
If you have a flat tyre, replace the tube. Replacement tyres and tubes
are readily available through the Dealer where you purchased your power
chair.
WARNING! Completely deflate the tyre before attempting
repair!
WARNING! To avoid possible injury, be sure that the
controller's power is turned off and the power chair is not in
freewheel mode before performing this procedure.
Follow these easy steps for a quick and safe tube or tyre
replacement:
1. Completely deflate the tyre (if pneumatic).
2. Use a 17-mm socket spanner and driver to remove the nut from the wheel axle. See figure 24.
3. Pull the wheel off of the axle.
4. Separate the tyre and tube from the wheel.
5. Remove the old tube and/or tyre and replace with the new tube or tyre.
6. Slide the wheel back onto the shaft and torque the nut to 16 ft.-lbs.
7. Inflate the tyre to 2.4 bar (35 psi) (if pneumatic).
WARNING! Overinflating tyres can cause them to explode and can result in personal injury.
WARNING! Do not use a high pressure hose to inflate your tyres.

shorting out the batteries and severely damaging your power chair!
