Terms and Conditions

The Mybility Warranty

Updated Jan 2017

The Four X DL CW4 range of chairs has a 10 year frame warranty, 5 years for the driving controller system, drive motors, actuators and seat. The batteries, tyres, charger, soft knee brace, chest harness and cushions are not covered in the warranty. The Four X Urban has a 5 year warranty.

The warranty is assigned to the individual named in the Mybility invoice. The Warranty can only be transferred to a new owner after inspection of the wheelchair and approval from Mybility.

This warranty covers faults that occur in normal operation of the wheelchair. The warranty does not cover faults caused by normal wear and improper or lack of maintenance as indicated in the owner’s manual and the service instructions.

Furthermore, the warranty does not cover faults originating from overloading or incorrect programming. The warranty does not cover wear and tear or accessories.

Normal wear occurs in parts such as tyres, rubber mountings, leaf springs, joints and slide surfaces. Increased noise of the driving motors is also caused by normal wear.

Faults and issues must be reported immediately to Mybility UK Ltd in writing and immediate action taken to prevent any further damage. Failure to do so may void the warranty.

Indirect expenses or transportation costs incurred in dealing with faults are not included in the warranty.

The warranty is only valid if Mybility UK Ltd carries out a yearly service or a Mybility and Chasswheel joint authorised service engineer, and covers the chair under normal operating conditions. Repairs or alterations  by non authorised service or repair agent may lead to further damage and will void the warranty. The yearly service is timed from the manufacturing date of the wheelchair shown on the chassis plate.

Written permission must be sought for any work carried out to the wheelchair, other than that allowed in the manufacturers manual,  failure to do so will void the warranty.

During the service the wheelchair must be brought up to manufactures specifications. Any damaged parts or issues which are assessed to potentially cause problems will be dealt with during the service and charged.

Failure to keep the wheelchair up to manufacturers standard specifications will void the Mybility warranty.

We are always happy to advise if there are any questions regarding your wheelchair and the warranty.

A storage and maintenance charge of £25 per week will be levied if the wheelchair has to be kept in the workshop due to non payment of services, goods or repairs for over 2 weeks from invoice date.


Where applicable the Manufacturers (Chasswheel) warranty terms and procedures take precedence over the Mybility warranty.

The Warranty Specifications are subject to upgrade and modification.



Extracts from the Manufacturers ManualWheelchair Servicing –

After driving under moisture circumstances, take care of drying the wheelchair for example by storing it in a warm space. Do not leave the wheelchair outside or in cold and moisture spaces. Not following these instructions might damage the wheelchair.

By servicing the wheelchair regularly, you ensure the functioning and safety of your wheelchair. A well serviced wheelchair is a long-term aid and it can last at least ten years if service is taken care of. Part of the servicing can be performed by users themselves (these operations are mentioned below). However, the more demanding service operations (such as electrical malfunctions, driving motors, actuators, frame parts, seat parts,  and other technical problems) can only be done by a qualified technician in order to maintain the warranty.

The manufacturer intends the wheelchair to be serviced/maintenanced by qualified technician (either distributor, service agent or the manufacturer) at least once a year.

Service card of the wheelchair is in the last pages of the Owner’s manual. Please take care of that the Owner’s manual goes with the wheelchair to the service. When it is a time to service the wheelchair, please contact to your FOUR X distributor.

Following routine operations the manufacturer intends the user to be responsible: – daily inspections
– weekly inspections
– cleaning the wheelchair

If necessary the user could ask assistant or some other person for help.

Daily inspections

Before beginning the drive check the general condition of the wheelchair visually. When the driving controller is switched off, check that the joystick is not bent or damaged and that it returns to the middle when released. Check that all the connectors are in place and undamaged and the cables are in good condition. Check that the thin protective rubber around the steering stick is not damaged. Handle the protective rubber with care. Make sure that the control module is well attached to the wheel chair. Do not over tighten the screws.

Weekly inspections

Brake tests are made on an even floor, with at least one meter of free space around the wheelchair. Switch on the control system. Check that the light bar is lit in one second or flashes slowly. Push the joystick slowly forwards until you hear the parking brakes working. The wheelchair may start moving. Release the joystick immediately, and you should be able to hear the sound of the brakes operating in a few seconds. Repeat this test three times also by pushing the joystick backwards, and to the left and right.

Check the operation of the lights, turn indicators and the balance adjustment. If the wheelchair has an electrically adjustable back and/or foot rest, also check their operation. In problem situations, do not use the wheelchair, but contact service.

Cleaning and disinfection the wheelchair

Clean the wheelchair with a moist soft fabric and diluted cleaning fluid. Avoid the use of undiluted cleaning fluids as these may damage the plastic and fabric parts of the wheelchair. Follow the recommendations set by the cleaning fluid manufacturers regarding the different materials. In the event of the control module becoming dirty, it must be cleaned immediately. Pressure cleaning or use of a shower is forbidden, as the wheelchair has electric units, which will be damage when wet.

The wheelchair can be disinfected totally for example by spraying the disinfectant on the wheelchair. The electronics of the wheelchair are in the battery box so keep the battery box closed during the disinfection. While disinfecting, notice the wheelchair’s texture surfaces (seat, supports) which should be disinfected with the suitable methods.

All the materials are tested acc. to ISO 7176-16 and the materials are inflammable.

Following operations the user is able to do with help of assistant or some other person:

  • –  measuring the tyre air pressure
  • –  changing tyres
  • –  disconnecting the batteries
  • –  installing the batteries
  • –  changing the lamp
