F. 2 Adjusting the brushes of the sweeper

Four adjustments can be made to the brushes to achieve the ideal and optimal setting for each sweeping situation.
• Brush pressure
• Forward angle of the brushes
• Sideways angle of the brushes
• Distance to the suction nozzle.
NOTE:
PARK THE MACHINE ON A FLAT, FIRM AND UNINTERRUPTED SURFACE.
NOTE:
USE AN SW27 OPEN-ENDED SPANNER AND AN SW30 OPEN-ENDED SPANNER TO ADJUST THE DIRECTION OF THE BRUSH UNIT.
NOTE:
ONLY A ONE-OFF ADJUSTMENT OF THE BRUSH PRESSURE IS REQUIRED.
F. 2.1 Brush pressure
The force the brushes exert on the ground is mostly due to their own weight. A relief spring reduces the brush pressure to prevent excessive wear of the brushes.
As the brushes slowly wear and become lighter the spring force will decrease proportionally and maintain the brush pressure at a constant level.
F. 2.1.1 Adjusting the brush pressure:
• Turn the adjusting nut (4) clockwise or anticlockwise.
• The brush pressure will then be decreased or increased, respectively.
• First, adjust the pressure to the minimum (the bristles just touch the ground).
• Next, use the adjusting nut (4) to adjust the brush pressure so that the bristles are pushed against the ground and bend outwards by 1 cm.
NOTE:
INCREASING THE BRUSH PRESSURE FURTHER SERVES NO PURPOSE. GREATER BRUSH PRESSURES WILL GREATLY INCREASE THE RATE OF
WEAR OF THE BRISTLES, AND WILL NOT IMPROVE THE SWEEPING PERFORMANCE.
