What to do if squeegee lift linkage arm/knob doesn’t raise or lower squeegee on Nilfisk-Advance Floor Machine?
- M
  Ms. Denise LewisSep 10, 2025
  If the squeegee lift linkage arm/knob doesn’t raise or lower the squeegee, it could be due to a worn cable bushing under the eyelet of the squeegee cable in the steering column, or a bent/sheared weldment linkage because the squeegee lift cable is too tight. Follow the instructions in the “Squeegee Lift Cable Adjustment - ST” section.

  Melissa SilvaAug 25, 2025
  If the squeegee lift linkage arm or knob on your Nilfisk-Advance Floor Machine isn’t raising or lowering the squeegee, the cable bushing under the eyelet of the squeegee cable in the steering column may be worn. Alternatively, the weldment linkage could be bent or sheared because the squeegee lift cable is too tight. To resolve this, follow the instructions in the “Squeegee Lift Cable Adjustment - ST” section.
