1. WORKING PRINCIPLE

The side brush wipes the dirt

at borders and edges into the

collecting track of the wide

lindrical broom.

This broom transports the

debris overhead and into the

dirt hopper. The fine dust

raised during this operation is

evacuated to the suspended

evacuated

the

suspended

filter by the suction fan where

the dust is separated. The air

returned into the environment

is clean.

3.2 Main Broom Adjustment

•Check Sweeping Track

• Park machine on level concrete or asphalt surface.

• (check inflation pressure of pneumatic tyres and adjust pressure if required)

• Turn on cylinder broom and let it run dry for a short time.

• 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

• Loosen left bearing shell of the torsion shaft

• Adjust parallelism at the stop screw

• Bearing shell

• Torsion shaft

• Stop screw

Sweeping Track Adjustment

• The sweeping track is adjusted after loosening of the handle and turning the star-shaped knob in the engine compartment.

possible wear of the sealing strips.

•

• Proceed to adjustment of the sealing strips at the bottom of the broom compartment on level ground only.

•

• Check the inflation pressure of pneumatic tyres and modify pressure if required.

•

• The sealing strip at the front folding apron has to be lightly inclined backwards and stand on the floor.

•

• Ground clearance of the left- and right-hand sealing strips is 5/64” (2mm)

•

• Ground clearance of the rear sealing strip is approx. = .20” (5mm)

•Note: Replace defective sealing strips immediately

3.4 Side Brush Adjustment

Adjust inclination of the side brush such that approx. 2/3of the brush perimeter has contact with the floor.

For right-hand side brush this ground contact is recommended between 11 and 3 o’clock seen in direction of travel.

For left-hand side brush this ground contact is recommended between 9 and 1 o’clock seen in direction of travel.

•Adjust inclination after loosening the gear holder and by displacing in the oblong holes.

•Adjust height of the lifted side brush at the Bowden cable such that the alignment of the top edges of the belt pulleys is

approx. 10°less than vertical axis. Then the distance between the top side of the V-belt and the fairing holder is about

15mm.
