VIII. CARE AND MAINTENANCE
Yearly Checks
Take your power chair to your Quantum Rehab Specialist for yearly maintenance. This helps ensure that your power chair
is functioning properly and helps prevent future complications.
Storage
Your power chair should be stored in a dry place, free from temperature extremes. When storing, disconnect the batteries
from the power chair. See VI. Batteries and Charging.
WARNING! If you fail to store the unit properly, the frame can rust and the electronics can be
damaged.
Cleaning Instructions
WARNING! Never hose off your power chair or place it in direct contact with water. Your power chair
has a painted, ABS plastic body shroud that allows it to be easily wiped clean with a damp cloth.
WARNING! Never use any chemicals to clean a vinyl seat, as they may cause the seat to become
slippery or dry out and crack. Use soapy water and dry the seat thoroughly.
Tire/Wheel Replacement
If you have pneumatic tires and you have a flat tire, you can replace the tube. If your chair is equipped with a solid tire
insert, then you must replace the whole wheel assembly. Replacement tires, tubes, and wheel assemblies are readily
available through your Quantum Rehab Specialist.
WARNING! To avoid possible injury, be sure that the controllers power is turned off and the
power chair is not in freewheel mode before performing this procedure.
WARNING! Completely deflate the tire before attempting repair.
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
