Height adjustment
The height adjustment is set to 3 mm at
the factory. If, despite an optimum an-
gle adjustment, streaks are produced,
the distance between the rollers and
floor must be adjusted by altering the
number of washers (Fig. 28/6) on the
holder.
In the case of very smooth floors, e.g.
laminated screed, PVC, linoleum, etc.:
Number of washers = 2. This corre-
sponds to a clearance of approx. 2 mm
to the floor.
In the case of very uneven floors, e.g.
poorly laid tiles (puddles form):
Number of washers = 4. This corre-
sponds to a clearance of approx. 4 mm.
