CTM FAQ

Why does my scooter/chair not move?

There are several possibilities which may cause the scooter/chair transmission system to stop working. The following steps should be taken to identify if the problem is in the controller or some other part of the system.
NOTE: Turn on key before beginning any diagnostics.
If the Self Diagnostic Warning Light if OFF:
Check that the battery power supply level is correct and that the batteries have no problem
If the Self Diagnostic Warning Light is FLASHING:
See FAQ Q2 for more details.
If the Self Diagnostic Warning Light is permanently ON:
This could indicate a problem with the potentiometer, motor, brake or any connecting wiring. Please contact your authorized dealer.

What should I do if the Self Diagnostic Warning Light is flashing?

Any fault condition on the controller will cause this. Flashing occurs in bursts, separated by a 2 second pause. The number of flashes in each burst is referred to as the Flash Code and indicates the nature of the individual fault. Faults that would affect the safety of the rider will cause the system to stop, whilst less critical ones will be indicated but allow the scooter/chair to continue driving. Some faults will automatically clear when they are removed, in which case the Self Diagnostic Warning Light will become steady and the system will operate as normal. Other faults are latched and must be cleared by turning the system off, waiting for 2 seconds, and then turning it back on again.

Why does my scooter/chair stop after a few minutes driving?

Check the Power Reserve Indicator light to see if the batteries need to be recharged.
The scooter/chair may be overloaded. Check the weight on the scooter/chair to ensure it is not over 135kg. Press the circuit breaker and try the scooter/chair again.
Check if the Self Diagnostic Warning light is flashing. Please refer to FAQ Q2 for more details.

Why can my scooter/chair not be run at maximum speed?

Check the battery condition from the Power Reserve Indicator lights. If they are lit in only the red or red and yellow zones, you should plan to recharge the batteries very soon.
If the batteries have been used for over 12 months, you should consider replacing them.
Check the motor bushes for abrasian. Replace with new brushes.
If the temperature of the motor or controller feels hot, contact your authorized dealer.

Why does my scooter/chair not run smoothly?

Check the motor brushes are not abrasian.
Check that the condition of the batteries is OK from the Power Reserve Indicator lights. It can cause a problem if the lights are extinguished quickly diving. It is recommended to replace the batteries.
If the scooter is surging while driving or the Speed Dial is not working properly, contact your authorized dealer to replace the potentiometer with a new one.

Why cannot I recharge my batteries?

When you recharge your batteries and the Right Battery Charger Light flashes green for over 40 minutes, this indicates abnormal charging has occurred. You should check that...
The battery charger is plugged in and switched on
The charger is plugged into a working power source.
The charger is the correct type
The charger fuse has not burned out
Note: Disconnect the charger from both the mains socket and battery charger socket before checking the fuse.
The scooter is turned off.
If none of these is a problem

How should I properly maintain my scooter/chair?

All technical maintenance and repairs should be done by an authorized dealer. The following require periodic inspection...
Tire Pressure (for air-filled tires only)
The condition of the tires and maintaining the specified tire pressures not only influence tire life, but also road safety to a considerable extent. Incorrect pressures are often a cause of tire problems and could result in an accident. The recommended tire pressure is 35lbs.
Tire Tread-Tire Damage
Inspect the tires frequently for damage, the presence of foreign bodies, unusual wear and sufficient tread depth (which should not drop below 1mm/0.04i if possible).
Front Caster Wheels (for Power Chair only)
If badly worn, replacement is recommended.
Electrical Connections
The battery terminals and all plug connectors need to be firmly attached. If battery terminals are corroded, please contact your authorized dealer for replacement.
Hardware
Ensure all fasteners are present and secure. Replace any which are missing and lighten loose ones.
Seat Towers
The seat should remove easily. If it does not, check that the locking levers in the seat release mechanism are operating correctly. Clean the seat towers, but do not lubricate.
