DAILY CHECKS
● With the controller turned off, check the joystick. Make sure it is not bent or damaged
and that it returns to center when you release it. Check the rubber boot around the base
of the joystick for damage. Visually inspect the boot only. Do not handle or try to repair it.
See your authorized service center if there is a problem.
● Visually inspect the controller harnesses. Make sure that they are not frayed, cut or
have any wire exposed. See your authorized provider if there is a problem with any of
these harnesses.
WEEKLY CHECKS
● Disconnect and inspect the controller and charger harnesses from the electronics
connector housing. Look for corrosion. Contact your local provider if necessary.
● Ensure that all parts of the controller system are securely fastened to your powerbase
wheelchair. Do not over tighten any screw.
● Check for proper tire inflation, there should be 30-35psi in each tire. If a tire will not hold
air, replace the tube.
● Calibrate the joystick if a noticeable difference in performance is detected or if the
joystick does not operate properly.
● Check the brakes. This test should be carried out on a level surface with at least three
feet of clearance around your powerbase wheelchair.
To check the brakes:
1. Turn on the controller and turn down the speed response adjustment knob.
2. After one second, check the battery gauge. Make sure that it remains on.
3. Slowly push the joystick forward until you hear the electric brakes click.
Note: The powerbase wheelchair may move when performing this test. Immediately
release the joystick. You must be able to hear each electrical brake operating within a few
seconds of joystick movement.
