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 high-gloss appearance.
Check all electrical connections. Make sure they are tight and are not corroded. Batteries must sit flat within
the battery well, with the battery terminals facing inward, toward each other. Refer to the frame decal 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. Visually
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 harness. Make sure that it is not frayed, cut, or has any wires exposed. See your
Quantum Rehab Provider if there is a problem with any harnesses.
Check for flat spots on solid tires. Flat spots could adversely affect stability.
Inspect the armrests 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 electronics tray. 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. Maintain but do not exceed the psi/bar/kPa air pressure rating indicated on each
tire for pneumatic tires. 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 three 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 backward, then left, and then right.
Monthly Checks
Check that the anti-tip wheels do not rub the ground when you operate the power chair. Adjust them as
necessary. See V. “Comfort Adjustments.”
Check for extreme wear on the anti-tip wheels. Replace them as necessary.
Check for drive tire wear. See a Quantum Rehab Provider for repair.
Check the rear casters for wear. Replace them as necessary.
Check the rear forks for damage or fluttering which indicates that they may need to be adjusted or have the
bearings replaced. See a Quantum Rehab Provider for repair.
Keep your power chair clean and free of foreign material, such as mud, dirt, hair, food, drink, etc.
