construction, substandard materials or poor workmanship.
Guarantee claims against Küschall AG may only be made by
the distributor and not by the wheelchair user.
Limitation of liability
The guarantee does not cover normal wear and tear, the
consequences of improper handling or damage, poor
maintenance and incorrect assembly or commissioning by
the purchaser or a third person or faults which are
attributable to circumstances beyond our control. The
guarantee is voided if modifications are made to the

1.4 Service life
We estimate that the Küschall® wheelchair has a service life
span of five years. It is difficult to state the exact length of the
service life of our products, and the length stated is an
estimated average life span based on normal use.
The life span may be considerably longer if the wheelchair is
used to a limited extent, and if it is used with care, maintained
and handled properly. The life span may be shorter if the
wheelchair is subjected to extreme use.
