5. Operation
5.1 Dry Vacuuming
For dry vacuuming, ensure the appropriate dry filter is installed. Connect the desired nozzle and switch on the vacuum cleaner. The 30-liter tank can be used with or without a dust bag, depending on the type of debris and user preference.
5.2 Wet Vacuuming
For wet vacuuming, ensure the washable filter elements are in place and suitable for wet use. Do not use a dust bag. The vacuum cleaner is equipped with a float valve that automatically stops suction when the tank is full to prevent overfilling. Empty the tank once the float valve activates.
5.3 Blower Function
To use the blower function, detach the suction hose from the inlet port and connect it to the exhaust port (usually located at the rear of the unit). The powerful airflow can be used for blowing leaves, debris, or inflating items.
5.4 Power Control and Tool Socket
The Multi II 30L T Inox features variable suction control, allowing you to adjust the power of the 1400 W motor as needed for different tasks. It also includes a power outlet on the unit. When a power tool is connected to this socket, the vacuum cleaner will automatically start when the tool is activated, providing efficient dust extraction during DIY projects.
6. Maintenance and Care
6.1 Filter Cleaning (Push&Clean System)
The Push&Clean filter cleaning system allows for quick and easy cleaning of the filter during operation. When the filter indicator signals reduced performance, press the Push&Clean button. This action reverses the airflow through the filter, dislodging accumulated dust and restoring suction power. Perform this regularly to maintain optimal performance.
6.2 General Cleaning
Regularly clean the exterior of the vacuum cleaner with a damp cloth. Do not use harsh detergents or solvents. Empty the tank after each wet vacuuming session and allow it to dry to prevent odors and mold growth. Clean the nozzles and hose to ensure unobstructed airflow.
6.3 Storage
Store the vacuum cleaner in a dry, protected area. Utilize the hose storage hook to keep the hose neatly organized. Ensure the tank is empty and clean before storing for extended periods.
7. Troubleshooting
If you encounter issues with your Nilfisk Multi II 30L T Inox, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Vacuum does not start | No power supply; damaged cord/plug; safety switch activated | Check power connection; inspect cord/plug; reset safety switch (if applicable) |
