7. Operation
During operation the machine has to be driven solely in floating position for better adaption to
ground unevenness and in order to avoid damage to the machine itself and to prevent high
brush wear. An additional contact pressure has to be absolutely avoided.
The depth wheel has to been adapted according to the brush position.
The adaption of the machine has to take place through the implement triangle or the three-
point hitch. The hydraulic hoses have to be firmly mounted. The clearance of all movable
parts has to be ensured.
7.1 KM 20 T / TS - Function mini-control panel with hydraulic cylinder
The control desk has 2 functions. On the one hand the telescoping of the main frame
with brush (2S1, left-right) and the other hands tilting the brush head (2S2: up-down).

8. Work deployment
Depending on the intensity of dirt on the surface to be cleaned and its material the
performance and the necessary approach differ very much and it can only be learnt by
practice and experience.
To get an optimal cleaning result while treating slick or smoothed surfaces or for removing
heavy earth and snow the brush disc should be inclined accordingly.
For weed cleaning an inclined position has always to be selected.
This is the only way for intensive cleaning.
Setup: very steep - for cobblestone
Slightly flatter - rectangular or interlocking stone

After changing a brush for tight fit of the screws must be checked and these may need to be
tightened after one working hour.
IMPORTANT Check all fittings and locks are secure.
10.1 brush change – Flat steel brush
The different brushes at the brush plate
Attached and can be solved simply by
the 4 screws and remove the brush insert
changing.
In the flat steel brush (KM20-5) are for fixing rubber bushings
mounted at the top.
These need to be cut from the inside along at 3-5 cm after a brush wear of about 5 cm to the
worn area with a knife (ideally utility knife), so that they retain their elasticity.
