5.1 General safety information on
installation work
Risk of damage to mobility device
Collisions can be caused if shim rings are
removed from the drive wheels during
installation work. Shim rings are frequently
placed between drive shaft and wheel hub
to compensate tolerances. Collisions can be
caused if these shim rings are removed and not
re-installed.
– Install all shim rings in exactly the same
positions they were in before dismantling.
