• Press I: Activate machine
• Press 0: Stop machine

Auto On/Off Operation for Electrical Tools* ?

The vacuum cleaner is equipped with an earthed socket for connecting an external electrical tool. The vacuum cleaner can be switched on and off by the connected electrical tool. Material is collected directly from the dust source. To comply with regulations, only connect approved dust-producing tools. The maximum power for the connected electrical appliance is specified in the "Specifications" section. Before switching the main switch to I, ensure the tool connected to the appliance socket is switched off.

Before Collecting Liquid ?

CAUTION: The machine is equipped with a float system that interrupts airflow when the maximum liquid level is reached. You will hear a distinct change in engine sound and notice a drop in suction power. When this happens, switch off the machine and disconnect it from the power supply. Never collect liquid without the float in place.

Emptying After Collecting Liquid

Before emptying the container, unplug the vacuum cleaner. Disconnect the hose from the intake. Release the latches to free the motor top. Lift the motor top off the container. Always empty and clean the container and float system after collecting liquids. Never collect liquids without the float system and filter installed. Empty the container by tilting it backward and pouring the liquid into a floor drain or similar. Replace the motor top on the container and secure it with the latches.

Emptying After Collecting Dry Material

Unplug the vacuum cleaner before emptying after collecting dry material. Periodically check filters and the dust bag. Release the latches to free the motor top. Lift the motor top off the container.

• Filter Cartridge: To clean the filter, you can shake, brush, or wash it. Let it dry completely before reuse.
• Dust Bag: Check the bag for fullness. Replace the dust bag when necessary. Remove the old bag. Install the new bag by placing the cardboard piece with the rubber membrane through the vacuum intake. Ensure the rubber membrane passes over the raised part of the vacuum intake.

After emptying, close the motor top and secure it with the latches. Never collect dry material without the filter cartridge and dust bag installed. Suction power depends on the filter and dust bag quality. Always use original filters and dust bags.
