Removing/installing the brush head
Note
The roller brushes or disc brushes must be removed before re-
moving and installing the new industrial cleaning heads (steel
housing), so that the cleaning head does not catch on the frame
parts. The cleaning head can be moved on the steering rollers.

Checking/adjusting the brush pattern
Note
● The cleaning head can be lowered and raised in test mode in
the "Brush head" menu. The red KIK key is required for this.
● The sweeping pattern must be adjusted on a flat insensitive
surface with new roller brushes.
● The suspension of the cleaning head must not be bent or dam-
aged.
● Both brush motors should draw the same current when the
cleaning head is correctly adjusted. This can be checked in
test mode.
● Turn the steering wheel to the straight-ahead position.
● Start the brush motors in test mode and move the lifting motor
down until both roller brushes rest on the ground.
● Note the current consumption of both motors. If there is a de-
viation, the cleaning head can be adjusted at the tie rods.
● If the tie rod nuts are tightened (shortened), the rear roller
brush presses harder into the ground. If the tie rod nuts are
loosened (extended), the rear roller brush pressure is re-
duced.
● Always change both tie rods in parallel.
● After correct adjustment, lock the tie rod nut.
