   • WARNING Empty the collection container of the vacuum cleaner after each use. This will also prevent spontaneous ignition of the contents of the container. After using the vacuum cleaner, the contents of the dust collection container may contain components that can pose a risk to health or the environment if disposed of incorrectly. The safe and proper disposal of these substances, as well as the disposal of the dust collection container if necessary, may only be carried out by professionals wearing suitable personal protective equipment. They must not be disposed of with household waste.
   • WARNING The unit must be decontaminated before these operations. Rooms in which these activities take place must have local filtered forced ventilation and the area must be properly cleaned afterwards.
   • ATTENTION Emptying, cleaning and filter changing may only by wearing suitable personal protective equipment. This protects the person from substances hazardous to health. Wear a dust mask (suitable for fine dust) when emptying the container of fine dust of any kind or substances hazardous to health.

Emptying dust/dirt from the collection container

• To empty dust/dirt from the collection container, remove the head of the appliance (see chapter “Safety instructions”).
• If you use a dust bag or waste bag, remove the bag and insert a new one.

Emptying liquid from the collection container

• To empty the liquid from the collection container, unscrew the drain plug and remove it.
• Now the liquid can flow out of the container. Dry the container with a clean cleaning cloth so that it is ready for the next use.

Store the vacuum cleaner accessories safely and in a space-saving way

• The accessories, hose and cable can be stored at the back of the appliance.

Storage

• To protect the unit from frost, empty the container.
• Store the vacuum cleaner in a dry place indoors.

Problem: Industrial vacuum cleaner emits dust
The industrial vacuum cleaner emits dust from the ventilation slots.
Troubleshooting:

1. If the industrial vacuum cleaner emits dust at the ventilation slots, switch off the unit immediately (to “OFF”). Ventilate the work area immediately and leave the room.
2. Check the dust bag/disposal bag for correct seating in the collection container.
3. Check the filter for perfect condition. If the filter is damaged or broken, it must be replaced.
   • ATTENTION Only operate the industrial vacuum cleaner with an inserted and undamaged filter. Make sure that the filter is in perfect condition.
   • ATTENTION When carrying out maintenance and repair work it is necessary to dispose of any contaminated objects which cannot be adequately cleaned. Such objects must be placed in impermeable bags in compliance with the relevant regulations for the disposal of such refuse. Objects that had to be disposed of have to be replaced and reinstalled.
4. Check the filter for cleanliness and correct seating in the unit. Clean the filter if necessary (see chapter “Safety instructions” in the operating manual). Allow the filter to dry before reinserting it into the unit.
   • VORSICHT Only operate the industrial vacuum cleaner with an inserted and undamaged filter. Make sure that the filter is in perfect condition.
   • VORSICHT When opening and closing the filter cover, there is a risk of crushing due to carelessness! Body parts can be crushed by the filter cover folding down quickly. Therefore, be particularly attentive, e.g. when resetting the retaining hook and then slowly lowering the filter cover. Do not allow yourself to be distracted by anything.
