It is a back to base warranty and is managed via the supply source where the system was purchased.
It is a limited liability warranty and does not cover damage to third-party wheelchairs.
Power Drive Systems and Wheelchair Compatibility
Wheelchairs are designed to safety standards that define how stable and how durable they must be to safely perform
during a typical usage lifecycle (ISO 7176:1-20). This standard is written to simulate typical use with reference to manual
propulsion and is tested to simulate a lifespan covering 350 km of travel*.
Using a wheelchair with a Power Drive System may expose it to wear and tear far in excess of the typical wheelchair
design lifecycle. Regular use with a Power Drive System over unsealed terrain and over extended distances may accelerate
wear of critical wheelchair parts.
It is important that the user contacts their wheelchair manufacturer/supplier to confirm the wheelchair warranty
conditions and service requirements if being used with a PAWS Powered Drive System.
