The travel direction can be changed during the cleaning
operation. This way, a certain position can be intensively
cleaned by driving back and forth several times.
1. Set the travel direction switch to "forward".
Note
To reduce vehicle width, the suction bar can be fastened to
the transport holder. Narrow spaces can then be easily
passed through.
Note
The inclination and height of the suction bar can be adjust-
ed to improve the vacuuming results (see chapter Adjust-
ing the suction bar).
Note
When the waste water tank is full, the float switch closes
the suction opening and the suction turbine runs at a high-
er speed. In this case, raise the suction bar and drive to the
location for emptying the waste water tank.

The speed is shown on the display during the adjust-
ment. The display is shown in percentage of the maxi-
mum speed.
