Frequently Asked Questions - SC400 NILFISK

How to install the brush on the SC400?
To install the brush, lift the brush head by levering on the handlebar. Position the brush under the head, then lower the head. Turn the selector to the washing program (brush symbol), press the validation push-button and the brush rotation levers simultaneously for a few seconds until it clicks.
How to adjust the solution flow?
The solution flow is adjusted using the solution flow push-button (reference 67). The LEDs (68) indicate the amount: 1 LED for minimum ECO flow, 2 LEDs for intermediate flow, 3 LEDs for maximum flow, and LEDs off for closed flow.
What to do if the motors do not work?
First check that the battery connector (29) is plugged in. If the batteries are discharged, recharge them. Check the fuses, especially fuse F0 (125 A) and F3 (5 A). If the problem persists, contact an authorized after-sales service.
How to clean the squeegee?
To clean the squeegee, stop the machine and set the selector to '0'. Disconnect the suction hose, loosen the fixing knobs and remove the squeegee. Wash it with water, paying attention to the conveyor compartments and the suction orifice. Wear protective gloves.
How to replace the rubber blades of the squeegee?
Remove the squeegee and the fixing springs. Replace the damaged front or rear blade. For the rear blade, if the edge is worn, you can turn it over to use the other side. Replace the springs and reassemble the squeegee.
How to charge the batteries?
Place the machine in a well-ventilated area. Make sure the selector is set to '0'. Use the built-in charger: plug the charger cable into the mains. The red/yellow LED indicates charging, the steady green LED indicates charging complete. For WET batteries, remove the recovery tank and open the caps during charging. Do not smoke.
What is the machine's autonomy?
The working autonomy with standard batteries (2 x 12 V - 76 Ah GEL) is approximately 1.5 hours. The autonomy may vary depending on use and battery condition.
How to drain the tanks?
Stop the machine, lift the squeegee and activate parking. Use the recovery water drain hose (16) and the solution level/drain hose (18). Rinse the tanks with clean water after draining.
What to do in case of suction system blockage?
If the suction is blocked, first check if the recovery tank is full: empty it. If the float is in the closed position, open the cover and reset the float. Also check that the suction hose is properly connected and that the squeegee is clean.
How to configure the machine for different battery types (WET or GEL/AGM)?
Disconnect the battery connector. On the electronic board in the electrical box, set the micro-switch (C) to the WET position for lead-acid batteries, or leave it in the GEL/AGM default position. Also consult the charger manual for the settings.

  • In case of fire, use a powder fire extinguisher, not a water one.
  • Do not tamper with the machine safety guards and follow the ordinary maintenance instructions scrupulously.
  • Do not allow any object to enter into the openings. Do not use the machine if the openings are clogged. Always keep the openings free from dust, hairs and any other foreign material which could reduce the air flow.
  • Do not remove or modify the plates affixed to the machine.
  • This machine cannot be used on roads or public streets.
  • Pay attention during machine transportation when temperature is below freezing point. The water in the recovery tank or in the hoses could freeze and seriously damage the machine.
  • Use brushes and pads supplied with the machine or those specified in the User Manual. Using other brushes or pads could reduce safety.
  • In case of machine malfunctions, ensure that these are not due to lack of maintenance. If necessary, request assistance from the authorised personnel or from an authorised Service Center.

P100627

NILFISK SC400 - NOTE - 2

CAUTION!

In case of brush/pad-holder motor overload, due to foreign bodies which prevent them from turning, or to excessively aggressive floors/brushes, the safety system stops the brush/pad-holder after about one minute of continuous overload.

The overload is shown by the three battery LEDs (68) flashing simultaneously.

To start scrubbing again after a brush/pad-holder stop due to overload, stop the machine by turning the knob (62) to "0". Restart the machine by turning the knob to one of the working programs.

Machine speed adjustment
