Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Powered chair will not drive / drives weakly / cuts out
- Confirm the batteries are charged and the freewheel / clutch levers are engaged for drive.
- Read the controller flash / fault code (count the flashes on the joystick module).
- Check the joystick centres to neutral and the motor / brake connectors are secure.
- Load-test or replace the batteries as a pair.
- Replace the joystick module or the drive controller as the code / testing indicates.
Symptom: Short range / battery will not hold charge (powered)
- Charge fully and confirm the charger reaches full output.
- Load-test the battery pack.
- Inspect for corroded terminals or a chafed loom.
- Replace both batteries together.
- Confirm range and hill-climb after replacement.
Symptom: Wheel / castor drag, wobble or bearing noise (manual)
- Lift each wheel, spin it and feel for roughness and check for play.
- Inspect the tyres / rims for damage and correct pressure (pneumatic).
- Repack or replace the wheel / castor bearings.
- Check castor-fork alignment and stem tightness.
- Confirm the chair rolls straight and free.
Symptom: Wheel lock (brake) will not hold / chair creeps
- Check tyre condition and pressure - a soft tyre kills brake bite.
- Adjust the wheel-lock to the manufacturer's engagement gap.
- Replace a bent or worn wheel-lock.
- Confirm the chair holds on a ramp with a load and both sides engage evenly.
- Check the anti-tip tubes are fitted and swing freely.
