4.1 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.
