All wheel bearings are prelubricated and sealed. They require no subsequent lubrication.
The body shroud has been sprayed with a clear sealant coating. You can apply a light coat of car wax to help it retain its
Check all electrical connections. Make sure they are tight and are not corroded. Batteries must sit flat within the battery tray, with the battery terminals facing inward, toward each other. Refer to the battery wiring label for the correct wiring layout.
WARNING! Even though the power chair has passed the necessary testing requirements for ingress of liquids, you should keep electrical connections away from sources of dampness, including direct exposure to water or bodily fluids and incontinence. Check electrical components frequently for signs of corrosion and replace as necessary.
Daily Checks
With the controller turned off, check the joystick. Make sure it is not bent or damaged and that it returns to the neutral position when you release it. Check the rubber boot around the base of the joystick for damage. Visu- ally inspect the boot. Do not handle or try to repair it. See your Quantum Rehab Provider if there is a problem. Visually inspect the controller cable. Make sure that it is not frayed, cut, or has any wires exposed. See your Quantum Rehab Provider if there is a problem.
Check for flat spots on solid tires. Flat spots could adversely affect stability.
Inspect the seating system, armrests, and front riggings for loose hardware, stress points, or damage. See your Quantum Rehab Provider if there is a problem.
Weekly Checks
Disconnect and inspect the controller from the power base. Look for corrosion. Contact your Quantum Rehab Provider if necessary.
Ensure that all parts of the controller system are securely fastened to your power chair. Do not overtighten any screws.
Check for proper tire inflation. Pneumatic tires should be inflated to the psi/bar/kPa air pressure rating indi- cated on the tire. If a tire does not hold air, see your Quantum Rehab Provider for replacement of the tube. Check the brakes. This test should be carried out on a level surface with at least 3 feet (1 meter) of clearance around your power chair.
To check the brakes:
1. Turn on the controller and turn down the speed level of your power chair.
2. After one second, check the battery condition meter. Make sure that it remains on.
3. Slowly push the joystick forward until you hear the electric brakes click. Immediately release the joystick. You must be able to hear each electrical brake operating within a few seconds of joystick movement. Repeat this test three times, pushing the joystick backwards, then left, and then right.
Monthly Checks
Check for drive tire wear. See your Quantum Rehab Provider for repair.
Check the caster wheels for wear. Replace them as necessary.
Check the caster forks for damage or fluttering which indicates that they may need to be adjusted or have the bearings replaced. See your Quantum Rehab Provider for repair.
Check the entire power chair for loose hardware and changes in the function or performance of the power chair. See your Quantum Rehab Provider for service and repair.
Keep your power chair clean and free of foreign material, such as mud, dirt, hair, food, drink, etc.
Yearly Checks
Take your power chair to your Quantum Rehab Provider for yearly maintenance, especially if you use your power chair on a daily basis. 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.
Batteries that are regularly and deeply discharged, infrequently charged, stored in extreme temperatures, or stored without a full charge may be permanently damaged, causing unreliable performance and limited service life. It is recommended that you charge the batteries periodically throughout periods of prolonged storage to ensure proper performance.
You may wish to place several boards under the frame of your power chair to raise it off of the ground during periods of prolonged storage. This takes the weight off the tires and reduces the possibility of flat spots developing on the areas of the tires contacting the ground.
Disposal of Your Power Chair
Your power chair must be disposed of according to applicable local and national statutory regulations. Contact your local waste disposal agency or your Quantum Rehab Provider for information on proper disposal of power chair packaging, metal frame components, plastic components, electronics, batteries, neoprene, silicone, and poly- urethane materials.
Cleaning and Disinfection
Use a damp cloth and mild,
If necessary, clean your product with an approved disinfectant. Make sure the disinfectant is safe for use on your product before application.
WARNING! Follow all safety instructions for the proper use of the disinfectant and/or cleaning agent before applying it to your product. Failure to comply may result in skin irritation or premature deterioration of upholstery and/or power chair finishes.
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.
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 entire wheel assembly. Replacement tires, tubes, and wheel assemblies are readily available through your Quantum Rehab Provider.
WARNING! The wheels on your power chair should only be serviced or replaced by a Quantum Rehab Provider or a qualified technician.
WARNING! Be sure that the power to the controller is turned off and the power chair is not in freewheel mode before performing this procedure.
WARNING! When changing a tire, remove only the center lug nut and washer, then remove the wheel. If any further disassembly is required, deflate the tire completely or it may explode.
