• The roof brush is lifted by the drive when the freewheel operates in driving mode
• The motor rotation direction is reversed to lower the brush
• The downward movement of the brush occurs by its own weight, controlled by the motor's speed
Mounting:
• Internal Freewheels FCN … R are supplied without bearing support
• To achieve the specified torque ratings, the outer ring must be installed in a housing with an external diameter K
