Main Broom - Nilfisk-Advance Retriever 300B Bedienungsanleitung Und Ersatzteilliste

Main Broom

The main broom loads the debris into the rear hopper.
Caution !
Never sweep wires, strings, etc..., because they may wind around the broom and the bristle can be damaged. NOTE: it is advisable to check
the broom periodically.
Main Broom Adjustment
The main broom must just touch the ground leaving a 1-3/16" (3cm) wide broom pattern (check when the machine is stationary on even surface,
drwg. A). When the main broom, no longer touches the ground leaving dirty traces, this means it is worn to a point where its lowering must
be adjusted as follows:
NOTE: The second notch and arrow 3 (fig 3) correspond to the working position with new main broom (1-3/16" / 3 cm broom pattern).
Loosen nut 4; rotate knob 5 clockwise moving it by one notch. Each notch corresponds to a 3/32" (2.5 mm) lowering of the broom, to again
adjust to a 1-3/16" (3 cm) broom pattern. Lock nut 4.
Main Broom Replacement
1 Remove the debris hopper and lift the walk-behind sweeper from the front side.
2 Remove the two screws 1 fastening the broom to drive pins 2.
