5. Operating Instructions

5.1 General Operation

• Ensure the vacuum cleaner is properly assembled with the correct filter for your task.
• Plug the power cord into a suitable electrical outlet.
• Press the ON/OFF switch located on the motor head to start or stop the vacuum cleaner.

5.2 Dry Vacuuming

For dry vacuuming, ensure the HEPA filter is installed and a dust bag is in place. This setup is ideal for collecting dust, debris, and other dry materials.

• Use the floor nozzle for large areas, the crevice tool for tight spaces, and the dust brush for delicate surfaces.
• Regularly check and empty the dust bag when it is full to maintain optimal suction power.

5.3 Wet Vacuuming

Before wet vacuuming, remove the dust bag and HEPA filter, and install the sponge filter. This prevents damage to the motor and ensures proper liquid collection.

• Use the appropriate nozzle for liquid pickup.
• The vacuum cleaner will automatically stop suction when the liquid level in the tank reaches its maximum capacity. Turn off the vacuum and empty the tank immediately.
• To empty the tank, unclip the motor head and carefully pour out the liquid, or use the drain plug located at the bottom of the container.

5.4 Blower Function

The vacuum cleaner can also function as a blower. This is useful for clearing debris from pathways, inflating air mattresses, or drying surfaces.

• To activate the blower function, detach the hose from the suction inlet and connect it to the blower outlet located on the rear of the motor head.
• Ensure the area is clear of people and loose objects before using the blower function.

5.5 Integrated Power Outlet

The LEHMANN LTOVI-1225 features an integrated 2000W power outlet, allowing you to connect power tools directly to the vacuum cleaner. This is convenient for tasks that require both cleaning and tool operation.

• Plug your power tool into the integrated socket on the vacuum cleaner's motor head.
• The vacuum cleaner will automatically start when the connected power tool is switched on, and stop shortly after the tool is switched off.
• Do not exceed the maximum power rating of 2000W for connected tools.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your vacuum cleaner.

6.1 Cleaning the Container

• After wet vacuuming, always empty and rinse the container thoroughly with water.
• Allow the container to air dry completely before reassembling or storing.

6.2 Filter Maintenance

• HEPA Filter: For dry vacuuming, the HEPA filter should be cleaned regularly by tapping it gently to remove dust or by rinsing it under cold water. Ensure it is completely dry before reinstallation. Replace the HEPA filter every 6-12 months, or sooner if suction power decreases significantly.
• Sponge Filter: After wet vacuuming, remove and rinse the sponge filter with water. Squeeze out excess water and allow it to air dry completely before storing or using again.
• Dust Bag: Replace the dust bag when it is full or when suction power noticeably drops during dry vacuuming. Do not attempt to reuse disposable dust bags.
