6 Operation
WARNING
Risk of injury. Damage to the filter system may allow harmful dust (health hazard) to escape.
▶ In an emergency (e.g. filter ruptured), switch the vacuum cleaner off, disconnect the vacuum cleaner
from all power sources (remove battery or unplug supply cord) and have the vacuum cleaner checked by
a trained and qualified person before further use.
6.1 Switching the vacuum cleaner on or off
You can prolong battery runtime by activating operation with reduced suction power.
→ To activate or deactivate, press the ECO button.
You can operate the vacuum cleaner by means of a Bluetooth module and corresponding remote
control unit (optional accessory).
→ Set the control switch to the BLUETOOTH position.
Read and observe the instructions on safety and use in the operating instructions of the accessory.
1. To switch on, turn the control switch to the ON position.
2. To switch off, set the control switch to the OFF position.
6.2 Bump-cleaning the filter
You can bump-clean the filter only when the vacuum cleaner is switched on.
1. Close off the end of the hose.
▶ This maximizes bump-cleaning power.
2. Wait until maximum vacuum has built up.
3. Press the
operating button.
6.3 Vacuuming up liquids
CAUTION
Risk of injury by dusts that are hazardous to health! Hazardous material that has been vacuumed up can
escape if a filter element is not used.

When the appliance is used to vacuum up drilling slurry and solid materials, there is a possibility of
the filter element being damaged. Take note of changes in suction power when vacuuming up these
substances.
1. Check the container level monitoring system. → page 9
2. If possible, use a separate filter element for wet applications.
