7.3 Adjustments
7.3.1 Brush Deck
The brush deck must be free to move
pivoted to its support so that the brush
acts parallel to the floor. This allows the
brush to evenly lean to the ground and
perform its function properly.
Requirements: Mounted brush, switched
off machine.
Procedure:
• Hook the brush to the base.
• Loosen the adjustment nuts.
• Lower the brush deck to the ground
so that the brush lies uniformly and
parallel to the floor.
• Tighten the adjustment nuts.

the brush has a chance to pass under
the base in an easy manner. In any case,
the lowest part of the deck, must have a
height from the ground of at least 7 cm.
