36 6 Maintenance and care
6.3 Changing the transverse cleaning brush
Free transverse cleaning carriage if required to permit easier change of the brush.
Power down the machine and secure it against reactivation.
The brush package can now be removed entirely from the motor shaft by loosening the
hexagon socket screw "A" (from the bottom in the brush shaft).
If the brush shaft cannot be removed easily, turn in the removal device (Item no.021
205) and remove the brush shafts with it.
Now clamp the brush shaft in the clamp (lower retention nut down)
Use an open-faced wrench (item no.021 202) to loosen the upper retention nut (coun-
ter-clockwise)
Replace worn brushes by new one.
After attachment of the new brushes, tighten the retention nut.
Install brush shaft and secure again with hexagon socket screw "A".
Activate the machine and perform a test run.
