7.3 Roller brush head
A unit with a working width of 108 cm is used as the roller brush unit for the
Scrubmaster B260R.
The roller brush unit can also be extended with a side brush unit.
Use the guide rail to adjust the dirt hopper so that the brush strip is positioned all-
round on the housing and the dirt hopper can still be easily inserted.
Due to the high dead weight of the roller brush deck, it is relieved by 2 springs. (Figure
7.6 A und B). Before the roller brush head can be removed, these springs must be
relieved. First loosen the fastening screw of the clamping plate (M8 x 20). Then loosen
the springs with the tensioning screw M10 x 150. Now the fixing bolts of the upper
rocker can be loosened from the lower rocker (M10 x 30). The springs are tensioned
in reverse order. (see Figure 7.7)
The spring in figure 7.6C is used to increase the pressure at the highest pressure
level.
