If the lift motor doesn't run and the display shows an error fault code, it indicates a lift motor electrical system failure. Please, refer to chart in “Main Controller Error Codes” for service actions.
Why does the squeegee lift linkage arm at the steering column keep bending or breaking on my Nilfisk-Advance Advenger BR 755 Floor Machine?
If the squeegee lift linkage arm at the steering column keeps bending or breaking, the squeegee lift cable is likely too tight. Follow the instructions in the “Squeegee Lift Cable Adjustment - ST” section.
Why lift motor runs in both directions but does not raise or lower the squeegee tool assembly on Nilfisk-Advance Advenger BR 755 Floor Machine?
The lift motor may run in both directions without raising or lowering the squeegee tool assembly because the threads in the moveable lift motor assembly drive tube are damaged (stripped), or the lift cable is damaged (stretched or broken).
What to do if squeegee lift linkage arm/knob doesn’t raise or lower squeegee on Nilfisk-Advance Advenger BR 755?
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.
How to fix squeegee hopping on Nilfisk-Advance Floor Machine?
If the squeegee is hopping, it may be because the wheel isn’t making contact with the floor. Reposition the wheel in the slot on the squeegee tool. Refer to the “Squeegee Adjustments” section.
What to do if squeegee tips are being driven into the floor on Nilfisk-Advance Floor Machine?
If the squeegee tips are being driven into the floor, adjust the squeegee using the adjustment knob, turning it clockwise (CW) to raise the tips.
What causes squeegee lift actuator overload in Nilfisk-Advance Floor Machine?
A squeegee lift actuator overload can be caused by binding or frozen squeegee lift linkage, excessive weight on the squeegee, or a short circuit in the wiring or actuator motor. Check for these issues, and repair or replace components as necessary.
What does squeegee lift actuator open mean for Nilfisk-Advance Advenger BR 755?
A squeegee lift actuator open can be caused by disconnected actuator wiring, an open in the wiring, or a defective actuator motor. Check for these issues and repair or replace. Also, check the controller output voltage at the BLK/YEL wire.
Why is there not enough adjustment of squeegee tool by turning adjustment knob on Nilfisk-Advance Advenger BR 755?
If there is not enough adjustment of the squeegee tool when turning the adjustment knob, the squeegee mount weldment bracket may be bent. Replace it.
