8.2 Cleaning
To clean the viaplus, use only conventional household detergents.
Clean the drive, handlebar and battery pack only with a moist (not wet) cloth.
Clean the bracket attached to the wheelchair with a moist (not wet) cloth.
Regularly clean the drive wheel, using a dry brush or compressed air cleaner.
Your viaplus is a low-maintenance device. With the exception of the tyres, the add-on
drive does not contain wear parts. To ensure that the drive or braking force respec-
tively of your viaplus is transferred properly, the tyres must not be worn beyond the
specified wear limit.
New tyres (see figure A) have a proper tyre profile and thus ensure optimised contact
pressure and safe drive behaviour.
If the profile and the side radiuses [R] are not visible any more, the tyre of your
viaplus is worn (see figure B). At this point, the diameter [X] of the tyre is 94 mm.
The tyre must be replaced without delay as there might not be sufficient contact
pressure to the ground.
To change the tyre, contact your authorised specialist dealer or Alber representative.
!
Should you observe a deterioration of the drive behaviour of your
viaplus (e.g. irregular rolling, slipping wheels), contact your author-
ised specialist dealer or Alber representative to check the tyres.
!
All service and repair work on the viaplus must be carried out by the
manufacturer, an Alber representative or an authorised specialist
dealer. If you encounter any problems with your viaplus, contact your
authorised specialist dealer or Alber representative.
