Height adjustment
The height adjustment is set to 3 mm at
the factory. If streaks appear despite an
optimum angle adjustment, the di-
stance of the rollers to the floor must be
adjusted by changing the number of
washers on the holder.
In the case of very smooth floors, e.g.
varnished floors, linoleum etc.:
Number of washers = 2. This corre-
sponds to a distance of approx. 2 mm to
the floor.
In the case of very uneven floors, e.g.
badly laid tiles (water does not run off):
Number of washers = 4. This corre-
sponds to a distance of approx. 4 mm to
the floor.
