9.2.2 Lowering mechanism / wheel shock absorbers
The wheel shock absorbers are virtually mainte-
nance-free. The damping effect will decrease after

The lowering mechanism / wheel shock absorbers and
their fixings need to be regularly checked for oil leaks,
damage, ageing, breakage and material fatigue.
Servicing work must only be carried out by qualified
specialists.
