• With the correct broom adjustment the parallel sweeping marks have to appear on the floor (sweeping track)
• The sweeping track width should be for the HM40R and HM47R (KS40R- KS47R) 2 Inches ± .2 inches (50 ± 5mm).
• Note: Exceeding the specified sweeping track parameter has a negative effect on the service life of the cylindrical broom.
• The sweeping track reduced as the broom diameter reduces due to wearing of the bristles.
• Adjust parallelism

• Adjust parallelism at the stop screw
• Bearing shell
• Torsion shaft
