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
boxes and battery well frame with the battery terminals facing inward toward each other. Refer to the battery wiring label
for the correct wiring layout.
!
All wheel bearings are prelubricated and sealed. They require no subsequent lubrication.
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 Specialist if there is a problem.
!
Visually inspect the controller communications cable. Make sure that it is not frayed, cut, or has any wires exposed.
See your Quantum Rehab Specialist if there is a problem.
!
Check for flat spots on solid tires. Flat spots could adversely affect stability.
Weekly Checks
!
Disconnect and inspect the controller and the charger harness from the electronics tray. Look for corrosion. Contact
your Quantum Rehab Specialist 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. There should be 35 psi (2.4 bar) in each tire. If a tire does not hold air, see your
Quantum Rehab Specialist for replacement of the tube.
!
Calibrate the joystick if a noticeable difference in performance is detected or if the joystick does not operate properly.
To calibrate the joystick, power off the unit, place the joystick in the neutral position, and power the unit back on. If
a problem still exists with your joystick’s performance, contact your Quantum Rehab Specialist.
!
Check the brakes. This test should be carried out on a level surface with at least 3 feet 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 your Quantum Rehab Specialist 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 Specialist for repair.
!
Keep your power chair clean and free of foreign material, such as mud, dirt, hair, food, drink, etc.
