The device has 2 operating modes:

1. Industrial vacuum cleaner operation (power socket not used)

2. Dust removal operation (power socket used)

1. Connect the suction hose and attach a suction nozzle or connect to the dust generating device, depending on the operating mode.

The horn sounds (intermittent tone) when the air speed drops below 20 m/s.

1. Set the turn switch to the correct hose cross-section.

The horn sounds (continuous tone) when the cooling air filter is clogged.

1. Allow the device to cool down. Clean/replace the cooling air filter.

Static charges are discharged through the earthed connection nozzles. This prevents sparking and electric shocks with electrically conducting accessories (included in the scope of delivery).

• For particularly dust-free dirt disposal when vacuuming small to medium quantities of fine dust, we recommend using a fleece filter bag with cap, order number 2.889-154.0 (5 pieces). The device is fitted with a fleece filter bag.

• For vacuuming large quantities of fine dust, we recommend using a dust bag with cable tie, order number 2.889-231.0 (10 pieces).

• We recommend switching off the "Automatic filter dedusting" function when vacuuming wet dirt with the crevice nozzle or the upholstery nozzle (optional), or when sucking mainly water out of a container.

• The device switches off automatically when the maximum fluid level is reached.

• When vacuuming non-conductive liquids (e.g. drill emulsion, oils and grease) the device does not automatically switch off when the container is full. The filling level must be continuously monitored and the container emptied on a timely basis.

• On completion of wet vacuum cleaning: Clean the main filter element using the filter cleaning. Clean the electrodes with a brush. Clean the container with a moist cloth and dry it off.

The suction hose is equipped with a clip system. All accessory parts with a nominal width of 35 mm can be connected.

1. Connect the mains plug.

2. Set the turn switch to the desired program.

1. Plug the mains plug of the power tool into the power socket on the vacuum cleaner. The vacuum cleaner is in Standby mode.

2. Switch on the device at the turn switch.

   Note

   The vacuum cleaner is automatically switched on and off with the power tool.

   Note

   The vacuum cleaner has a startup delay of up to 0.5 seconds and an after-running time of up to 15 seconds.

   Note

   See the Technical data for the permissible power rating of the power tool.

3. Remove the angle piece from the suction hose.

   ---

   

4. Install the tool adapter on the suction hose.

5. Connect the tool adapter to the power tool.

   ---

   

6. Set the minimum volume flow on the turn switch for suction hose cross section. The scale shows the suction hose suction hose cross section.

   Note

   The different suction hose cross sections are necessary in order to adapt to the different connection cross sections of the processing machines.

   Note

   For operation as a dust removal device for mobile operation (processing machine plugged into the vacuum cleaner) the integrated monitoring system must be adjusted to suit the connected processing machine (dust generator). This means that the user must be warned when the flow rate drops below the minimum value 20 m/s needed for correct vacuuming.

The device is equipped with a special filter dedusting function, which is particularly effective against fine dust. The main filter element is automatically cleaned every 7.5/15/60 seconds (depending on use) using an airflow (pulsing sound).

1. Set the turn switch to program 2 (TACT AUTO).

2. Power dedusting (for particularly severe contamination of the main filter element): Set the turn switch to program 2, seal the suction pipe or bender with your hand and wait for the automatic filter cleaning to finish (lasts 15 seconds).
