Important Technical Specifications (inferred from the manual)
Usage Features
Maintenance Features

The Nilfisk SC400 is a compact and efficient walk-behind scrubber-dryer designed for cleaning various floor types. It is an ideal machine for daily cleaning tasks in small to medium-sized areas, offering both scrubbing and drying capabilities in a single pass. The device is manufactured by Nilfisk-Advance A/S, a company trusted since 1906.

Function Description:

The primary function of the Nilfisk SC400 is to clean hard floors by applying a cleaning solution, scrubbing the surface with a brush or pad, and then vacuuming up the dirty solution, leaving the floor dry and ready for use. This process is achieved through a combination of a solution tank, a brush motor, a vacuum motor, and a squeegee system. The machine is designed for ease of use, with clear operating guidelines and troubleshooting steps provided in the manual.

Important Technical Specifications (inferred from the manual):

Power Source: Battery-operated, requiring a charger cable for connection to the electrical main.
Battery Life: A full recharge takes 10-12 hours, and charging after every use is recommended to prevent damage to the batteries. The machine features a battery level indicator with a red light indicating low battery.
Solution Tank Capacity: The manual shows a transparent hose for emptying the solution tank, suggesting a reasonable capacity for typical cleaning tasks.
Recovery Tank Capacity: Similar to the solution tank, a hose is provided for emptying the recovery tank, indicating a suitable capacity for collecting dirty water.
Brush/Pad System: Accommodates various brushes or pads suitable for different floor types and cleaning requirements. The manual emphasizes using the appropriate brush/pad for the floor.
Squeegee System: Features a lever for lowering the squeegee and handwheels for fastening, ensuring effective water pick-up.
Solution Flow Control: Equipped with a switch to control the flow of cleaning solution, allowing adjustment based on the type of cleaning and preventing excessive solution application.
Maximum Solution Temperature: The cleaning solution temperature must not exceed 40°C.

Usage Features:

The Nilfisk SC400 is designed for straightforward operation, as outlined in the "Operating Guidelines":

Preparation:
- Disconnect the battery charger cable from the electrical main.
- Fill the solution tank with an appropriate cleaning solution, adhering to dilution instructions and ensuring the temperature does not exceed 40°C.
- Install the squeegee, fasten it with handwheels, and connect the vacuum hose.
- Place the correct brush or pad-holder under the deck.
Operation:
- Switch on the brush and vacuum motors.
- Press the enabling push-button along with the brush levers to start floor cleaning.
- Press the handle switch to engage the brush and run the machine.
- Use the solution flow control switch to adjust the solution flow as needed. If solution flows outside the brush housing, reduce the flow.
- Lower the squeegee with the lever during operation.
Troubleshooting (from "Troubleshooting" section):
- Machine doesn't work: Check if the power cable is correctly connected and if the battery is charged.
- Suction doesn't work: Verify the suction hose is correctly installed and cleaned, check the vacuum grid and gasket in the recovery tank, inspect squeegee blades for damage or dirt, and ensure the recovery tank cover is properly closed with a good gasket seal.
- Machine doesn't clean: Confirm correct water settings, check if the solution tap is open, and ensure the solution filter is cleaned.
- Brush doesn't work: Check if the brush is correctly installed and not worn out, look for brush motor overload (indicated by 3 battery LEDs flashing simultaneously), and remove any external materials avoiding brush rotation.

Maintenance Features:

Regular maintenance is crucial for the SC400's performance and longevity, with several steps integrated into the post-operation routine:

Post-Operation Cleaning:
- Empty the recovery tank using its hose.
- Empty the solution tank using its transparent hose.
- Wash the recovery tank and the vacuum grid with clean water.
- Clean the filter by removing the transparent cover and gasket.
- Remove and clean the brush/pad.
- Take off the squeegee and remove any debris.
- Check and clean the squeegee blades.
- Clean the machine exterior using a damp cloth, and a neutral cleaning product if necessary.
Battery Charging:
- Connect the battery charger cable to the electrical main to charge the batteries. A full recharge takes 10-12 hours.
- It is recommended to charge the batteries after every use. Failure to do so, especially after the red light illuminates, can damage the batteries.
- Ensure the red socket is left disconnected after recharge if the machine is not used daily.
Storage:
- Park the machine with the recovery tank cover open to allow for drying and prevent odors.

The Nilfisk SC400 is designed to be a reliable and user-friendly floor cleaning solution, emphasizing both operational efficiency and ease of maintenance to ensure consistent performance.
